    A flooded basement cleanup and remediation process can be extremely frustrating and messy for anyone who has ever dealt with one. When you factor in the cost of repairs, you'll see why basement waterproofing is a good idea. In addition to preventing flooding and moisture damage to your basement floor and walls, basement waterproofing also keeps your home dry and mold-free.

    You have options when it comes to basement waterproofing. Both the interior and exterior of a building can be made watertight. Let's take a look at each one.

    If you're thinking about finishing your basement, or if you've had a flood, you may want to look into basement waterproofing methods. Basement waterproofing can be accomplished in two ways: externally or internally.

    At Hitch Property Constructions, we offer the best range waterproofing services to rectify your water issues.

    Waterproofing the Basement Interior

    The first step in preventing future water damage from leaks or flooding is to properly seal the interior. The first step is to dig a trench down in the basement. Next, a sump pump is installed in the trench to collect water that has accumulated. Concrete is then used to seal the trench. To prevent water from leaking into the basement, internal sealants are applied.

    Basement sump pumps are the most effective way to prevent flooding, even though sealing cracks in the walls, floors, and ceilings won't stop it from happening in the long run. In the event of a flood, the sump pump can quickly remove large amounts of water, preventing water damage and other threats.

    In basement waterproofing, concrete breakout is a common practise. Detecting leaks and potential leaks in the basement and foundation walls can be done by using this tool. This is a difficult and dangerous task for a layperson, but for a waterproofing professional, it is a simple fix that takes little time.

    In Virginia, summers can be oppressively hot and muggy, making it difficult to spend time indoors. Consider installing a dehumidifier if you notice that the air is too moist. It will reduce your basement's moisture content by about half. Your air conditioner will run less frequently if you lower the humidity levels in your home.

    Floodwaters won't enter your home if you instal a basement drain pipe with grating.

    Waterproofing the Basement Exterior

    The soil around the basement, no matter how beautiful the landscape appears, is always a potential danger. Water puddles and damp cold floors are telltale signs that your home is experiencing moisture problems from the outside. This prevents mould and mildew from taking hold of your home, as well as moisture buildup and stains, by using exterior waterproofing. You can keep water out of your home by using both interior and exterior drainage.

    Water must be diverted away from the basement and foundation walls before the exterior can be made waterproof. You'll need gutters and downspouts to accomplish this. It's a simple process that won't disrupt your yard or landscape in any significant way. Yours should be working properly and not clogged if you have one in place.

    Install drainage panels on top of a waterproofing membrane that has been installed around your foundation. Groundwater will not be able to come into contact with the basement walls, allowing it to flow down the foundation and into a drain beneath the foundation. You should make sure that the perimeter is sloped to avoid collecting water. If it helps, adjust the slope or grading of the soil around the house.

    As a driveway owner, you should install drains to divert rainwater away from your home. Make certain that yours has metal grates to prevent clogging from debris and leaves.

    Signs That You Need Basement Waterproofing

    As a homeowner, water intrusion is one of the most worrisome issues. Damage to your home's structure, health concerns, and the risk of further damage are all critical considerations when dealing with water damage.

    Depending on the extent of the damage, you may need to replace insulation, drywall, and even the framing if water gets into your home.

    To remediate mould, you'll need a lot of money and a lot of time, which isn't good for your health or wallet.

    Contact a waterproofing expert immediately if you notice any of the following signs in your home:

    • Water puddles in the basement
    • Water stains on the floor or walls
    • Leaks coming from the floor or walls
    • Condensation on basement windows or doors
    • Swelling or warped doors
    • The smell of dampness that doesn’t seem to go away
    • Visual confirmation of mould or mildew
    • Cracking on the floor or walls

    Your home's foundation may be compromised if a water leak has gone unnoticed for a long period of time or if moisture issues have not been properly addressed.

    Waterproofing is only a small part of the foundation repair process, which is overseen by structural engineers. A foundation repair specialist should be called if you notice cracks, leaks or bowing in your basement walls.

    Why Interior Repair is Usually a Better Approach

    Wet basements can be caused by a variety of issues. A leaky basement should be addressed from inside the house, according to our experience.

    It takes less time

    Extensive time and effort are required to remove and replace the soil, drainage systems outside the foundation walls, decks, fences, landscaping, and utility lines. The possibility of damaging tiles, utility lines, and root systems is also increased, necessitating more time to fix.

    It is less expensive.

    A few hundred dollars may be spent on injecting into a crack in the interior, but removing soil and landscaping and replacing it could cost several thousand. Repairing and replacing damaged tiles, utilities, fencing, decks and landscaping is less likely to result in additional costs.

    It can be done during any weather.

    When the ground is frozen or wet, no exterior work can be done. It also necessitates the scheduling of an entire crew for dry weather. Their ability to work on your project may be hampered by their other commitments. A single person can perform an interior crack injection in any weather.

    It detects the source of the leak.

    You can't be sure where the water is coming from if you can't see it on the inside walls. There could be any number of rod holes leaking from the outside. This leak can only be found by peering through a hole in the interior wall.

    It repairs voids in the wall.

    In contrast to exterior repairs, which only patch the surface, foundation walls that have cracks injected with a polymer can have their voids filled through the entirety of the wall.

    It lasts longer than concrete patches.

    The conditions in the soil will eventually cause concrete patches to crack and leak for the same reason that the foundation developed a leak in the first place: they are the same conditions. Polymers are impervious to water and respond to changes in temperature by either expanding or contracting.

    It is less dangerous.

    There is always a greater risk of the soil caving in or another type of accident occuring on the excavation site whenever crews dig a hole on the exterior of a foundation wall. This is a risk that is present whenever crews dig a hole anywhere else.

    Quality of the Repair Depends on the Person Doing It

    Injections into cracks as a method of crack repair in Virginia It makes no difference to the terms of the warranty whether the leak is repaired from the inside or the outside of the building. Both of these approaches are commonplace in the industry; however, if exterior repairs were not successful, the companies that provide them would be out of business. The quality of the work, similar to the quality of anything else, is the best indicator of whether or not a repair will be successful.

    The level of expertise and positive attitude displayed by the waterproofing professional who is working on your leaking basement is of the utmost importance. They have to be able to make a precise diagnosis of the issue and fix the leak without resorting to any alternative methods. In most cases, the best way to determine which contractor will do the best job of repairing the leak in your basement is to look at the contractor's reputation and to read personal testimonials.

    Methods for Waterproofing the Interior of Your Basement

    When it comes to waterproofing your basement from the inside, you have a variety of options to choose from (both in terms of methods and types of products). The following are the top four most common approaches:

    • Waterproof concrete coatings: Thick, cement-like coatings that permanently adhere to your walls. They’re intended for concrete or masonry, such as walls made of cinderblocks. You will apply the material by brushing it on using the type of brush that is recommended by the instructions for that brand. It is not possible to apply the vast majority of these coatings to walls that have previously been painted.
    • Sealant made of silicates used in concrete; these products are sometimes referred to as "densifiers." They can't be applied to painted walls either, just like concrete coatings can't be. They can also be used for masonry and cement walls without causing any problems. They work their way into the wall, preventing them from falling off. In most cases, once they have reached their final stage of curing, you can paint over them. If you intend to do that, you should make sure to check the label first.
    • Plastic sheets or panels combined with a drainage system are the following: This is one of the more pricey solutions; rather than attempting to stop the water from penetrating the basement walls in any way, the water is simply contained between the wall and the plastic. After that, it makes its way down the plastic and into a drainage system, which is eventually emptied by a sump pump.
    • Paint for the interior that is waterproof: The interior of the basement wall is painted with a specialised acrylic or latex paint, and the paint is applied in a layer that is very thick (or in many layers that are thin, depending on the brand).

    Avoid Flood Water and Moisture Problems

    The presence of water in the basement is the worst nightmare of any homeowner. In addition to causing the wood to rot and the metal to rust, damp basements provide ideal conditions for the growth of mould and the flourishing of pests, both of which can infest your home. The cost of removing mould and repairing damage caused by water can easily run into the thousands of dollars. Why should you wait until your basement is flooded before taking action?

    By waterproofing both the interior and exterior of your basement, you can avoid all of the problems that have been described above. DIY projects should never be attempted because you run the risk of applying the wrong solution to your basement. We strongly recommend that you use solutions for waterproofing the interior and exterior of the basement in areas where there has been leakage.

    Waterproofing the interior of a building may be sufficient, but you can never be sure what mother nature has in store for you. There is a chance that you will wake up one morning to find floodwater in your basement. For this reason, it is best to instal basement drainage systems on both the interior and exterior of the basement.

    Should I Waterproof The Inside Or Outside Of My Home?

    If you have recently experienced flooding or are thinking about finishing your basement, you may be interested in researching the various ways in which you can waterproof your space. There are two distinct approaches to waterproofing your basement, one being from the outside, and the other from the inside.

    The wall has been coated with one of a couple ‘waterproofing’ substances: pitch vinyl or with concrete.

    The covering of the wall with pitch, as is done by builders most of the time, is the most common tactic. After the wall has been cleaned, a coat of toss spray is applied to both the walls and the footer. The most significant problem with sour is that it quickly turns brittle and cracks at the point where the walls and footer meet.

    This is by far the most problematic aspect (this is a point of constant motion for a home stinks ). Because of this, the majority of people have started using vinyl sheeting in the construction scenarios that follow. Vinyl does not crack and is impervious to water in its entirety.

    After that, the vinyl is adhered to the wall all the way down to the footer. The most significant drawback of all the vinyl is that, despite the fact that it does not tear, it can never be completely attached to the concrete footer and walls, and water can flow around it and through the base. This is the most significant drawback.

    Exterior drainage.

    In addition, this tactic requires digging the external foundation all the way down to where it meets the ground and installing a drainage pipe. After that, this tube will direct the water that collects at the base to a local drainage area so that it can be removed. Because of this, there must be a runoff area in close proximity to the building that is at least one foot (and preferably more) below the basement floor. The use of systems similar to these is extremely common among contractors.

    The percentage of people who are able to survive the refilling of this base dirt is so incredibly low that it is almost inconceivable. The most significant problem associated with this particular drainage system is that the combined pressure of the sand and mud coming from above is too great for any drainpipe to be able to withstand it. The drainage pipes typically become clogged rather quickly.

    The second possibility involves waterproofing the interior, which is the option that is most likely to be chosen.

    The first step in waterproofing the interior of the cellar is to dig a trench on the inside of the base wall that surrounds the outside of the space. A pump is positioned at the bottom of the well, ready to remove the water when it is needed. In addition to this, offering support and warranties on them is a lot less difficult.

    Basement waterproofing inside or outside

    There are a lot of things to think about if you are trying to decide whether or not you should do the waterproofing of your basement inside or outside. When it rains a lot or there's a particularly strange storm, I often find that some people's basements have small leaks that only happen occasionally. According to the information provided by these individuals, it may take a very long time before the water begins to seep into the basement, and even after the storm has passed, the water may continue to seep in for a while longer. Then I have conversations with people who tell me that almost any time it rains or snow melts, they can see water coming into their basement within a few minutes.

    These two scenarios typically represent two distinct types of issues, and they can be one way to determine whether you should prioritise waterproofing the inside or the outside of your building. Surface water from precipitation and snowmelt, as well as groundwater that accumulates below, are both potential sources of water that could make its way into your basement.

    If you have a problem with surface water, you will notice that the walls of your basement are wet starting around the grade, which is the level of the dirt outside your home. Rain and snow will naturally run towards the house if the driveway, patio, sidewalk, or even sunken soil leading up to the house has a slope that is steeper than the slope leading up to the house. They can deteriorate the original seal on your basement walls, which can lead to dampness and cracks in the walls. It's possible that you've addressed each and every one of these issues, but you're still dealing with persistently damp basement walls, paint that's flaking off, mould, and a musty odour, etc.

    This indicates that the seal to the foundation on the exterior is no longer functioning properly, and that water is entering your walls as a result. In this scenario, waterproofing your basement from the outside will prevent water from reaching your foundation and will protect it from any additional damage that may occur. Although it is possible to instal an interior system that will provide you with a dry space, the condition will not be stopped in its tracks.

    Imagine that you are dealing with the opposite problem, where the water seeps in only along the floor at the base of the wall after an extended period of wet weather, but the walls themselves are mostly or completely dry. If this is the case, you are probably dealing with a buildup of groundwater under your foundation that has nowhere else to go besides the seams where the basement floor meets the walls.

    In such a scenario, an interior basement waterproofing system will drain the water away from your home, catching the water before it can accumulate in the basement. This type of system is frequently referred to as a hydrostatic relief system because it relieves the pressure that causes water to enter a building through seams in the floor and walls. In this particular scenario, waterproofing the exterior will not prevent the water from building up under your floor, and you will continue to experience seepage even under those weighty conditions.

    Your house can be repaired no matter if you require waterproofing work on the interior, the exterior, the foundation, or some combination of the three. Sometimes the problem can be solved by doing something as easy as directing water away from your house.

    In the majority of instances, the most effective way to handle a water intrusion problem is to begin by addressing the tasks that are the least difficult.

    For instance, you should first have your gutters inspected, then consult a drainage expert about the grade of your yard, and only then should you worry about the interior of the basement. If those solutions do not resolve the issue, then you will most likely have to move on to the exterior of the building.

    The use of a dehumidifier can be of tremendous assistance in preventing the growth of mould. Keeping the windows and doors of the basement open can also be of assistance because it will allow fresh air to enter and will speed up the drying process. You can do what you can to prevent problems from developing, but you can only help with the problems that you can see or smell.

    Whether you are purchasing a brand-new home, one that is under construction, or one that has been on the market for some time, it is critical to have a professional conduct an inspection so that they can evaluate the effectiveness of your waterproofing methods.
