    Concrete waterproofing – best methods and materials

    Waterproof Concrete

    Sheet membrane systems

    Membranes Cold-applied polymer-modified bitumen is a membrane made of asphalt-modified polymers and polyethylene. The polymer makes asphalt more viscous and less temperature-sensitive than asphalt alone. Self-adhering sheets eliminate asphalt adhesion toxins. They boost tensile strength, acid-resistance, resilience, self-healing, and bondability.

    Despite advances, problems remain. Membranes must be sealed, lapped, and finished at corners, edges, and between sheets. Sheet membranes must be smooth, without voids, honeycombs, or protrusions. Protection boards must be installed because the membrane can puncture and tear during backfilling.

    Despite all these drawbacks, sheet membranes have been the industry standard in waterproofing for many years. Impact resistance, toughness, and overall durability keep them in use.

    Liquid-applied membranes

    Liquid-applied membranes are applied with a brush, spray, roller, trowel, or squeegee and contain urethane or polymeric asphalt in a solvent base. Membranes with high elastomeric properties are usually applied to cured concrete. Newer technologies have negative side effects.

    Proper thickness and application are key to liquid-applied membrane waterproofing. They require skilled, experienced labor, a clean, dry substrate, a protection layer before backfilling, properly cured concrete to avoid adhesion and blistering, and a sub-slab on horizontal applications. UV radiation and foot traffic degrade liquid-applied membranes. Liquids contain toxic VOCs (VOCs).

    Liquid-applied membranes are used when prefabricated sheets won't work on projects with multiple plane transitions, intricate geometric shapes, and protrusions.


    A new type of waterproofing has been used worldwide for three decades. These integral admixtures are added at the batching plant or on-site and react in the concrete. Instead of a positive or negative side barrier, they make the concrete a water barrier. Densifiers, water repellents, or crystalline admixtures can be integral concrete waterproofing systems.

    Densifiers, water repellents, or crystalline admixtures can be integral concrete waterproofing systems. Densifiers react with calcium hydroxide formed during hydration to increase concrete density and slow water migration. They can't seal cracks and joints, so they're not waterproof or repellent. Hydrostatic pressure requires extra waterproofing to protect concrete from damage.

    Hydrophobics repel water. Liquid products include oils, hydrocarbons, stearates, and long-chain fatty acid derivatives. Hydrophobic systems work well for damp-proofing but not hydrostatic pressure. Stress-induced concrete cracking creates water passageways. Concrete affects the effectiveness of water repellents.

    Crystalline admixtures

    Crystalline-based systems are usually dry, powdered, and added to the concrete mixer. Crystalline-based systems are dry and hydrophilic. Crystalline systems use available water to grow crystals inside concrete, blocking moisture that can damage it. Concrete itself blocks water from any direction. Crystalline formula contains no VOCs and can be recycled.

    Crystalline admixtures improve installation. Crystalline admixtures can be shipped in dissolvable, palpable bags and thrown into the concrete batch during mixing, unlike traditional membrane waterproofing. Combining steps with concrete placement speeds up construction and reduces labor costs.

    Plaza decks or rooftops that move frequently should be waterproofed differently.

    Elastomeric Coating

    Elastomeric coatings are good waterproofing materials. Elastomeric coatings are safe, durable, and attractive ways to protect concrete. Painting and priming apply them. Implementation is easy. Concrete must be primed before polymer paint is applied. Polymer acrylic paint likes gaps, cracks, and surface irregularities, so two coats should be enough. Elastomer has elastic properties and reshapes itself to fit its structure. This protects concrete buildings from air and water for many years, regardless of temperature. This material is effective.

    First-class elastomeric coating is ten times thicker than paint for exterior walls or roofs. It makes a structure's exterior waterproof with a thick, flexible coating. They can seal as thin as a hair for an airtight and waterproof seal, unlike other coatings or paints. It works on plaster, concrete, and walls. Walls and roofs can have elastomeric coatings. The liquid elastomeric coating dries, hardens, and binds to the structure as it bends and rises.

    This material is flexible. It protects a structure from damage and provides a waterproof coating. The elastomeric coating can be colored several ways and retains its color. It helps maintain the exterior's attractive appearance by preventing damage, wear, and tear. People who want to buy a building for investment purposes and sell it at market value should use materials that keep the building fresh and new for a long time and save money over time.

    Silicone Sealant

    Let's discuss another waterproofing product. Silicone sealant is waterproof. Silicone sealants protect and waterproof concrete. Silicone can fill and seal cracks up to 0.6 cm thick. It's used for pearlwork and waterproofing. Silicone or polyurethane sealant works well for protecting concrete structures. So you can use a silicone filler when renovating a house or after rough construction. Sealant can be sprayed or applied with a paint roller. Silicone sealant is the most nuanced waterproofing material.

    Liquid adhesive silicone sealant. It's gel-like. It's chemically different from other organic polymer adhesives. Silicone remains flexible and balanced at high and low temperatures, unlike other adhesives. Silicone sealant resists chemicals, moisture, and weather. This reduces the chance of creating and repairing errors.

    Silicone sealants, not adhesives, are needed. Cured silicone dries. Silicon isn't hard, but requires patience. Temperature should be between 4°C and 37°C, and humidity should be between 5% and 95%. If the sealant is thick, it may take days to harden. It requires patience.

    How to Waterproof Concrete Surfaces

    Step 1: Clean and Prepare the Concrete Surface

    These essential steps get the concrete ready to accept the waterproofer; don't skip them!

    • If necessary, protect your walls with a plastic sheet. Sweep the concrete thoroughly with a push broom to get rid of dirt and debris. Then thoroughly sweep it a second time. You'll be surprised at how much dust gets left behind in the first sweeping!
    • Make sure the concrete is completely dry. Pour the cleaner/etcher into a large watering can. Sprinkle the cleaner/etcher on the surface and leave it on for 10 to 20 minutes.
    • Scrub the surface vigorously with a long-handled scrub brush. If the cleaner/etcher begins to dry as you work, mist it lightly with water to keep it wet.
    • After scrubbing, hose down the surface thoroughly to rinse it, but don't let the rinse water go down a storm drains.
    • If desired, use a squeegee to push water off the concrete, then let the surface completely dry, at least overnight (24 hours is better).

    When it has been properly prepared, the surface should have the texture of sandpaper with a medium grit. It's possible that you'll need to apply the cleaner/etcher more than once in order to get the desired effect on stained concrete or concrete with a smooth, dense finish. If you run your finger lightly over the surface of the concrete after it has dried, and it comes away with dust on it, you should rinse it again. There should be no residue or loose concrete after the surface has dried.

    Step 2: Apply Waterproofer/Sealer to the Concrete Surface

    Depending on the porosity of your concrete, a gallon of waterproofer can cover 250 square feet.

    • Pour some waterproofer into a large painter's tray. If you're sealing an indoor area, use the paintbrush to apply a sealant to the floor along the edges of the walls. That way, you'll avoid touching the walls with the roller in the next step.
    • Apply the sealant to the roller from the painter's tray, loading it fully. Roll it onto the concrete, saturating the surface completely. If the sealer puddles, spread it to drier areas.
    • Let the first coat of sealer dry.
    • If your product requires a second coat, roll it on in the opposite direction from the first coat to ensure even coverage.
    • Allow the sealer to dry and cure. Most sealers require 24 to 48 hours to cure.

    Step 3: Concrete Surface Aftercare

    In general, you should wait three days before allowing heavy foot traffic on a sealed surface and 14 days before driving on it. Wait 30 days before mopping with mild detergent.

    Heavy-traffic areas may need annual maintenance. Depending on the sealer and surface wear, you may need to reseal periodically. If water soaks into the concrete instead of beading, and if it's scratched, dull, or dirty, it's time to reseal. Acrylic waterproofing lasts 1-3 years. Epoxies, polyurethanes, and polyaspartics last 5-10 years. Penetrating sealers may never need reapplying.

    Which Waterproofing Material Should I Choose?

    Best waterproofing material is the answer. How do you pick the best construction materials? Best waterproofing materials expensive? No! Many factors must be considered when building.

    Knowing what you're waterproofing will help you choose the best materials. Waterproofing wood, concrete, and bricks requires different materials. To choose the right waterproofing chemical, you must determine the water density or water traffic on the material's surface. Climate is a major factor in water traffic. How much rain do you need to build? Is the temperature change too big from cold to cold or the same? Was the house site a riverbed or rocky area? Does the apartment have other leaks? Such questions will help you choose the best waterproofing materials.

    Waterproofing materials and methods vary by application. Annual applications may require partial, spot, or complete reapplication of the product.

    If you're waterproofing for the first time, choose a product that can be applied to multiple materials. Waterproofing helps wood, concrete, and brick. You can save time and money by using the same waterproofing materials on all home surfaces.

    When choosing a waterproofing material, consider the time needed for the best protection, the application duration, and the number of applications. Find a material that won't harm plants and animals. If you have kids, find child-safe waterproofing materials.

    To find the right waterproofing material, consult a specialist. Preliminary research is required. Learn the topic. You can also get advice from experts who use proven products.

    FAQs About Waterproofing

    Waterproofing is required at concrete structures to keep moisture out of the facility and to protect the structural components of concrete and imbedded reinforcing steel. If the integrity of the concrete is maintained, it can remain waterproof.

    The best approach is to waterproof the concrete itself, by using penetrating hydrogel treatment. This treatment is ideally applied in two forms to the slab, as an admixture, and spray-applied to the exposed face.

    We suggest you use Coo-Var Damp Shield. This is a two-part epoxy resin coating designed to prevent moisture from rising and penetrating your concrete floor. Moisture can cause you serious issues in the future so this is an important step to waterproofing a basement floor.

    Outdoor concrete sealers are not only worthwhile but necessary. Experts who recommend having a concrete surface sealed are doing their customers a big favor. Without this extra layer of protection, concrete will absorb moisture and may begin to crack, spall, flake, and discolor, among other things.

    However, if you use low quality concrete sealers, the surface may become slippery. Some sealers have high solid content which fills the pores on the concrete. In that case, a solid layer is formed on the surface of the pavement that becomes slippery when exposed to wetness.
