    There are some homeowners who mistakenly believe that the interior of their basements are all that has to be waterproofed. When finished, they believe they will not have to worry regarding drainage or leaking if they keep the basement's walls as waterproof as feasible. The problems caused by this flawed way of thinking aren't limited to the cellar at all.

    Because it is your own property, the status of your house is very important to you. It's your home, which means it's also a substantial financial investment. When you finally got the keys to your new residence and signed the dotted line, do you remember how happy you were? I can't imagine why someone wouldn't want to make sure their home is in nearly perfect condition.

    A flooded basement is a common result of living in a region that receives a lot of precipitation or experiences frequent snowfall and melting. You've decided to get basement waterproofing because you're the type of conscientious owner of the property that other people aspire to be like.

    However, there is a dizzying array of options, and there are many different approaches to basement waterproofing. Also consider hiring a professional to do the job for you. Also, how different is inside waterproofing from external waterproofing? The question is then, shall we go into this matter further and discover out?

    Waterproofing: The Key Distinction Between Interior and Exterior


    Exterior Waterproofing

    Waterproofing the exterior of a house involves installing features like gutters and downspouts to collect rainwater and channel it away from the building. This is why it's so important to regularly clear up your gutters. The use of a waterproof membrane is also crucial for exterior waterproofing.

    Putting this membrane around your home's base can help keep water out and stop the concrete from cracking from absorbing moisture. The next thing to do is set up some sort of outdoor drainage system, like a French drain, to carry away the water. The installation of this system could be labor-intensive because it necessitates digging besides the house's foundation.

    When the drain tiles are laid in the trench around the whole perimeter of the home, the gravel surrounding them and the remainder of the system is backfilled. The water will be diverted away from the building's foundation and out of the basement thanks to the drain tiles. Using this technique will necessitate digging, but the payoff could be worthwhile.

    External structure waterproofing is more costly than interior waterproofing because it involves more work and more materials. But it succeeds admirably in keeping water far away from your home's base. Water won't be able to leak into your basement or even the rest of your house if the foundation is kept dry and doesn't get brittle and damaged or cracks. The initial investment in a high-quality external waterproofing system will be more than offset by the savings you'll enjoy over the long run.

    Interior Waterproofing

    When a home's interior is water proof, any water that finds its way into the basement is prevented from damaging the foundation. Pipes and drains are put either below the foundations to collect groundwater or inside the building to catch leaks.

    Any surplus water is sent into a sump pit, a huge basin typically installed in a basement. The sump pump, which is housed in the sump pit, is responsible for removing water from the basement and diverting it away from the foundation of the building. That was the last stage. Once the water level in the sump pit reaches a certain point, the pump will start pumping water automatically. Most modern sump pumps have a backup battery that allows them to keep working even if the power goes out, which can happen during a particularly powerful storm.

    Waterproofing the inside of a structure is possible through the usage of vapour barriers as well. These, which can be constructed of plastic or foil sheets, are hung along the walls of your basement to act as a moisture barrier. Interior waterproofing is the process of repairing and sealing foundational cracks and leaks in addition to installing an interior drainage system to divert excess water away from the basement.

    This aids in the avoidance of flooding. These can be simply sealed to prevent the buildup of excess moisture or humidity in your home. A good internal waterproofing system can do a lot to reduce the likelihood of flooding in your basement. Compared to exterior waterproofing solutions, these drainage systems are less expensive and easier to instal.

    There are benefits and drawbacks to waterproofing the inside along with the exterior. Waterproofing from the inside cannot be used to drain water that has already collected in your basement, thus it is not useful at preventing water seepage. But you can use it to get rid of the water that's already in your basement.

    Keeping water away from your home's foundation and preventing moisture from getting into your house or your basement can be accomplished through costly exterior waterproofing. What's most important is that you're doing something to keep your home at a steady, pleasant temperature and free of moisture.

    Is It Possible to Waterproof a Basement From the Inside?

    Because they sit below ground, basements must be built to handle flooding. Damage to the basement's support columns, ruined belongings, mould growth, and a drop in the home's resale value are all the results of a basement that is too damp to be used normally.

    Because it is so common and significant, water seepage into the basement can cause a lot of stress for homeowners. You might not give much thought to a tiny drip or puddle, but it could be an indicator of a much bigger problem.

    Excessive humidity in a basement, if not properly handled, can lead to expensive damages. Therefore, it is crucial to understand the various methods that can be used to keep a basement dry.

    The Term “Interior Waterproofing” Refers to What Exactly?

    Fixing the basement's drainage and ensuring the home's exterior remains watertight Everything done inside the basement is mainly for managing water that has been able to get through the foundation, thus the term "interior waterproofing" is misleading. The process of sealing the house from the outside and the basement from the inside to prevent water damage. While redirecting the water may help mitigate some of the damage, it won't fix the exterior problems that allowed water inside in the first instance.

    There should still be effective waterproofing on the inside of your basement. Maintaining a properly functioning sump pump and doing routine checks with a moisture detector can keep water from accumulating around your foundation and inflicting costly damage. The caulking from around doors and windows should be watertight, and any holes in the floor or walls should be patched. If the basement hasn't been finished and there are no immediate plans to do so, implementing an interior weeping tile solution can help channel water.

    The inside of a basement cannot be waterproofed effectively enough to provide a long-term solution. Although externally weakening the foundation may buy you some time, it will not avoid future issues. When water collects in the basement, it nearly invariably points to an issue on the outside of the foundation. If you fail to adequately waterproof the exterior, moisture and mould can swiftly creep throughout your home, posing major health risks. The basement's durability is maximised when both the inside and exterior are waterproofed.

    Waterproofing the Inside and Outside Together

    Construction of a Waterproof Stone Basement The best approach to fortify your basement is to waterproof its exterior. Stone constructions last for a very long time. While interior waterproofing helps keep water damage from spreading, exterior repairs take care of problems where they first show up. This prevents water from entering the home, safeguards your foundation's concrete or stone from erosion, and prevents the latter from crumbling.

    Exterior repairs, as opposed to merely constructing a membrane or employing a patching solution inside the basement, halt the growth of significant gaps and cracks over time. A weeping tile system and crushed roundstone barrier will divert water away from the edges of the foundation rather than letting it seep in and causing you to stop it inside the wall. The water will be directed away from the foundation's edges to achieve this.

    Internal basement leaks are something that external waterproofing won't be able to prevent, but internal waterproofing can. If you have a well-thought-out system in place for your basement, you won't have to worry about further damage in the case of a pipe burst or washing machine hose failure. Yet, if you give these factors equal importance, you can lessen the chances of serious damage to your basement and other parts of your home in the future.

    Interior Benefits

    Considering these three factors, the option of utilising the internal system may be the best one to go with:

    • The area is inaccessible from the outside due to space constraints or other barriers.
    • The source of the water is not a leak in the foundation. There is still the problem of hydrostatic pressure, which occurs as the groundwater below the concrete slab rises and falls, causing water to flow into the basement through cracks in the slab or the junction between the floor and the wall. This water below the house's foundation may possibly be an indication of an underground stream.
    • For unfinished living spaces, the Internal System offers a practical and affordable option.

    Waterproofing a Basement Is Essential for Mould Prevention and Better Indoor Air Quality

    If mould starts to spread within your home, you can have a serious problem on your hands. If mould is allowed to colonise your home, it will steadily degrade the structure and may even pose health risks to your family.

    Allergens, irritants, and even mycotoxins, which are hazardous compounds, are produced by moulds and are the cause of allergic reactions. Anyone who inhales or touches mould or mould spores is at risk of developing an allergic reaction.

    People who suffer from bronchitis are especially vulnerable to airborne irritants like mould and pollen. Microscopic spores are the first stage of mould growth; they are too tiny to be visible to the unaided eye but can be seen floating around in the air, both outside and indoors. When there is moisture on a wet interior surface, mould growth might begin. Only when there is a source of moisture, such as water, dust, or both, can mould begin to grow. When the dust settles on a wet surface, it might begin to expand and spread throughout the house. With any luck, you now have a better grasp of the dangers posed by a wet or damp basement.

    One of the most common mistakes homeowners make when dealing with basement flooding or moisture is putting off fixing the problem until it's more convenient. That's a major mistake that could have fatal consequences. Damage from water intrusion will worsen over time if not addressed, and mould development must be halted immediately. In that case, not only could you be putting your health at risk, but the removal process itself could wind up costing you more money.

    The word "mould remediation" describes the steps taken to eliminate a mould problem and is likely to come up in your search for a solution if you suspect there is mould in your house. Since mould is often not spotted until it has spread extensively, it is in your greatest advantage to have a professional inspector take a look at the situation as quickly as possible. Certified mould remediation specialists understand how to deal with mould inside the home and use cutting-edge techniques and solutions that adhere to all applicable codes and standards. They will have the resources at their disposal as well.

    However, nearly no one would argue that avoidance is your best choice when it comes to avoiding mould growth within your home. As a result, if you see any signs of water or moisture damage, you should get it fixed or checked out very away.

    Inside Water Seepage That Needs Waterproofing

    There are numerous causes and origins of water in a basement. Water in the basement has its origins in the soil outside the house.

    Almost everywhere on Earth, water can be found in the ground, however it may be buried to great depths in some areas. The "water table," the average depth to which groundwater extends below the surface, can be higher or lower during periods of severe rainfall or drought.

    Since hydrostatic pressure is created by the weight of water below the foundation, it pushes upwards against the floor of the basement. There is a force acting on the walls due to the lateral pressure created by water present in the soil from around foundation. Water seeping in through cracks in the foundation is a symptom of either hydrostatic or osmotic pressure, which both grow as more water is absorbed by the soil.

    Basement Floor Cracks

    The basement floor is merely an aesthetic feature and adds no structural value to the house's foundation; a basement with a dirt floor is as sturdy as a foundation with a poured hard slab. The majority of basement floors are made of poured concrete. This is why it's common for basement floors to have just four inches thick of poured concrete.

    Since the flooring is so thin, cracking often occurs when hydrostatic pressure rises beneath it as a result of the earth absorbing more water. This may occur in a single place or in several. Since the flooring isn't actually part of what holds the building together, these fissures won't cause any problems with the substructure. However, they are often a source of seepage, especially after severe or prolonged rainfall that raises the water table.

    Wall Cracks  

    Typically built of poured concrete, basement walls are the most likely entry point for water. Even though poured concrete foundation walls are thick (eight to ten inches), non-structural cracks can form due to lateral strain from moist soil around the foundation. Wall fractures can also be caused by foundation movement or sinking.

    These wall cracks aren't structural, as seen by their random appearance and thin width (usually less than an eighth of an inch). Structural foundation cracks, as opposed to cosmetic ones, are always more than a sixteenth of an inch broad and always appear in the same pattern. This points to a more significant problem with the base. Walls that have been structurally damaged will have a vertical crack down the centre and two diagonal cracks across the top corners. There are vertical racks at each corner of the space where the wall has started to separate from the wall facing it, but they are not visible from within the space.

    Cove Joint 

    When building a foundation, the first step is to create a footing, a wide slab of concrete that acts as a bearing surface for the structure and defines its outer edges. When the footing is set, the foundation walls can be poured in forms or built immediately on top of the footing by masons. In either case, the footing and the walls are not joined together, so a tiny gap develops between them.

    The basement floor will be poured once the foundation is complete. There will be an even tinier space between the basement floor and the walls because the floor does not bind to the walls. Water can enter the basement through this area (the cove joint) if hydrostatic pressure develops beneath the foundation.

    How to Prevent Water From Penetrating Interior Basement Walls

    Some preventative measures against water seepage into basements are outlined below.

    Keep Water Away From Your House’s Base

    Land grading is something to consider if water is seeping into your basement. If the ground slopes towards your home's foundation, water from storms or other inadvertent sources may leak into any below-grade rooms. Because of this, floods may occur in certain areas.

    If there is more than a six-inch drop in elevation every 10 feet away from your home's foundation, you may have drainage issues. This is why poor grading might threaten your home's stability.

    To avoid having water seep into the basement, you'll need to slope the yard. This will help to keep water out of the room. To keep your basement dry, it's crucial to ensure that the landscaping has a favourable grade (away from your base).

    The proper method of grading. Mounds of earth or trough-shaped depressions can be built to alter the terrain and reroute water flow.

    Fill Cracks and Gaps

    Hydraulic cement should be used to seal any gaps or crevices in the basement that have been found to be allowing water to seep in. A couple of the additives in this cement make it stick better, and the others allow it to grow without cracking.

    The sealant's quick drying period allows it to seep deeply into the cracks and crevices, sealing them off from any water infiltration. If you are unable to accomplish this on your own, it is recommended that you hire a reputable basement waterproofing service.

    Use a Waterproofing Solution on the Masonry

    The present paint on the basement walls should be stripped off if the foil test reveals water seepage (indicating an inside water source). Apply a substance formulated to prevent water from entering masonry to the inside of the walls and then seal the area. After the paint has dried completely, a watertight seal will be formed between the sealant and the surface. That's what will occur after the paint is completely dried. outs.

    Downspouts and rain gutters work together to divert water away from a structure. They help in ways that make it less of a hassle to maintain the integrity of the building's framework.

    Those who don't already have them should think about getting gutters and a sump pump. If you have previously installed gutters, don't forget to connect the downspout extensions made of metal or plastic to the gutters. It will aid in the collection of any surplus water or runoff and the subsequent draining of that water far from your base of operations.

    Build a Drainage System Within Your House

    Having a sump pump system and a French internal drain installed in your basement is the best way to keep water from getting in or accumulating there. It's the most common approach.

    Now that this difficult operation has been finished, we can fix the water problem once and for all. To instal the French drain that will lead water from your basement to the sump basin, you will have to make a trench on the flooring of your basement.

    The next stage is to add more gravel to the trench. The drain tile leads the water to a sump basin, where it is collected before being pumped out of the house using an electric pump.

    There's nothing that causes more worry for homeowners than a damp basement. Water seepage is a major problem in basements and cellars since they are constructed below ground level.

    Quickly investigating the problem and finding an all-encompassing remedy can help you preserve your property and assure the continued health and safety of its occupants.

    Waterproofing the basement's inside is a fantastic idea if you want the space to stay dry and tidy. Because it doesn't necessitate extensive excavation on the building's outside, it's a lot more appealing.

    Plus, it won't break the bank for you. In order to maintain a mold-free and dry basement, waterproofing is an absolute must. You need to take some preliminary measures before you can see the outcomes you desire.

    FAQs About Basement Waterproofing

    To protect a basement from water damage, mould, and mildew, waterproofing is a crucial step that must be taken. 

    There are many approaches to waterproofing a basement, but the particular circumstances will determine the most effective one. Installing a membrane that acts as a waterproof barrier on the basement walls and floor is a common and effective method. This membrane forms a barrier that stops water from passing through it under normal circumstances. 

    Caulking or tape that is watertight can be used to seal cracks and joints in the basement, which is yet another standard method. This helps to prevent water from getting in through cracks and crevices in the structure. 

    In addition, it is essential to clean the gutters and downspouts so that water is not directed toward the basement. This will prevent any potential flooding. You can help to keep your basement dry and free from water damage if you take these steps and follow the instructions.

    The interior basement waterproofing method is a well-liked choice because it does not require significant excavation on the exterior of the building, and it can, in some circumstances, be completed in a concise amount of time and at a low cost. 

    This also makes it a tempting opportunity for do-it-yourselfers, who, regardless of their level of skill, typically fail to stop the seepage because they either do not have access to the appropriate materials or do not have the knowledge to install permanent improvements.

    In many do-it-yourself (DIY) attempts to waterproof the interior of a basement, hydraulic cement and caulk are the materials of choice. The problem is that neither of them works; using them to stop seepage in the basement will only delay the inevitable call to a professional who can waterproof the basement.

    The process of waterproofing the exterior of your home entails excavating the soil that is around it and then using a potent sealant to repair any leaks that are found. It is generally agreed that waterproofing systems installed inside basements are superior and more effective at preventing dampness in basements.

    The following are some of the causes of basement leaks: When it rains frequently or heavily, the ground may become saturated, resulting in the formation of hydrostatic pressure, also known as water pressure. This pressure can force moisture and water through the walls and floor of your basement. The soil that is looser around your foundation has a greater propensity to take in more water.

    Inspect Your Basement Walls and Floors for Cracks

    A common cause of water in the basement after rain is a cracking foundation wall. Like a cup with a hole serves as useless for holding liquids, your foundation is futile for keeping water out of your basement if they're cracked.
