    A guide to different types of materials used in waterproofing



    Polyurethanes are formed by reacting a polyol with a diisocyanate or polymeric isocyanate with catalysts and additives. Polyurethane can be made with a variety of diisocyanates and polyols to meet specific application needs.

    Polyurethane (PUR and PU) consists of organic units linked by carbamate (urethane) links. There are thermoplastic polyurethanes as well as thermosetting polyurethanes. Di- or triisocyanate and polyol react to form polyurethane polymers. Polyurethanes are alternating copolymers because they contain two types of monomers. Polyurethane isocyanates and polyols contain two or more functional groups per molecule.

    Polyurethanes are used to make high-resilience foam seating, rigid foam insulation panels, microcellular foam seals and gaskets, durable elastomeric wheels and tires (like roller coaster, escalator, shopping cart, elevator, and skateboard wheels), automotive suspension bushings, electrical potting compounds, high-performance adhesives, surface coatings and sealants, synthetic fibres, carpet underlay, hard-plastic parts, etc. Di- and tri-isocyanates and polyols make polyurethane. Other materials are added to aid processing or modify polymer properties.

    Cementitious coating

    Cementitious coating is a binder-held, Portland cement-based coating. A cementitious coating protects substrates from corrosion by maintaining the pH level above 4.0 at the metal/coating interface, where steel corrodes more slowly. Two-component, thixotropic, cementitious modified polymer coat. It adheres well to concrete and steel. This coating protects concrete or other substrates from acid gases, moisture, and chlorides. This coating is elastic, hard, and alkaline. In sulphate-contaminated soil, the cementitious coating protects concrete.

    The cementitious coating waterproofs concrete and other mineral substrates internally and externally. It's good for underground structures, roofs, and decks. The cementitious coating protects highways and coastal structures from chlorides and increases reinforced concrete's durability.

    EPDM rubber

    EPDM rubber is a synthetic rubber with many uses. EPDM is an M-Class rubber under ASTM D-1418, which includes polyethylene-saturated elastomers (the M deriving from the correct term polymethylene). EPDM is made with ethylene, propylene, and a diene comonomer for sulphur vulcanization. EPR, ethylene-propylene rubber, contains no diene units and can only be crosslinked with peroxides. Ethylidene norbornene (ENB), dicyclopentadiene (DCPD), and vinyl norbornene are EPDM dienes (VNB). EPDM is copolymerized polyethylene with 45-85% propylene to reduce crystallinity.

    EPDM is a semi-crystalline material with ethylene-type crystal structures at higher ethylene contents, becoming amorphous at 50 wt %. EPDM has better heat, light, and ozone resistance than natural rubber, SBR, or polychloroprene (Neoprene). EPDM can be formulated to withstand temperatures up to 150°C and can be used outside for decades without degrading. EPDM is elastic down to -40°C, depending on grade and formulation. EPDM flashing with fleece used to waterproof roofs. EPDM is always compounded with fillers like carbon black and calcium carbonate, with plasticisers like paraffinic oils, and has rubbery properties only when crosslinked. Crosslinking is done with sulphur, peroxides (for heat resistance), or phenolic resins. Electron beams are sometimes used to make foams and wire and cable.


    Bituminous waterproofing protects homes and businesses. Bitumen (asphalt or coal-tar pitch) is a sticky, viscous, waterproof organic liquid. These systems are used to build roofs as felt or roll roofing.

    Bitumen is used as the glue or binder for asphalt concrete in road construction (70%). It's also used to make roofing felt and seal flat roofs. Bitumen properties change with temperature, so there is a specific range where viscosity allows adequate compaction by lubricating particles. Low temperature prevents aggregate particles from moving, preventing required density.

    Roofing felt

    Roofing felt is used to make shingles and roll roofing. Bitumen compositional membranes have been used for decades as residential and commercial waterproofing. The first underside polymer membrane is a solid, glass-reinforced background. The top layer is mineral granules, and a bituminous mixture encases them. Felt paper is used as an underlayment (sarking) for roofing and siding, and as a membrane in asphalt built-up roofing (BUR) systems. Purposes: "...separate roof from deck...shed water Secondary weather protection..." Rapid application of roofing underlay protects the roof deck during construction and is required for UL-rated roofs.

    Separating the roof from the deck protects it from resins in some sheathing materials and cushions unevenness, old nails, and splinters. The underlayment sheds water that penetrates the roof from a leak, wind-driven rain or snow, or ice dams. Underlays may increase roof temperature, which causes asphalt shingles to age, and wet felt paper wrinkles, which (rarely) shows through asphalt shingles. Not installing an underlay may void the roof's warranty.

    Mastic Asphalt

    Mastic asphalt (MA) is a dense mixture of coarse or fine aggregate, bitumen, and additives (for example polymers, waxes). Low-void mixture is designed. Adjusting the binder content fills voids and may cause a slight excess. Mastic asphalt can be poured and spread when warm. It's not site-compacted.

    Its durability and seamless application make it one of the few membranes that can handle heavy foot and vehicular traffic, including HGVs, while remaining waterproof. No application is too difficult, and damage is easy to repair. Mastic asphalt can be quickly laid, reducing project costs. It cools quickly, allowing foot traffic in two to three hours, depending on temperature.

    The waterproof membrane is fast becoming the material of choice for schools, offices, shopping centers, hotels, and even churches due to its excellent weather resistance and 50-year lifespan.


    Thermoplastics are plastic polymers that soften at high temperatures and harden when cooled. Most thermoplastics are heavy. Intermolecular forces between polymer chains weaken with temperature, resulting in a viscous liquid. In this state, thermoplastics can be reshaped and used for injection molding, compression molding, calendering, and extrusion. Thermoplastics don't form irreversible chemical bonds like thermosetting polymers (or "thermosets"). Thermosets don't melt when heated but decompose when cooled.

    Waterproof TPU fabrics combine a thermoplastic polyurethane membrane with a base textile, such as nylon or polyester, to create flexible, durable, waterproof materials.

    TPU has many good qualities. It's abrasion-resistant, tear-resistant, has excellent bending and tensile strength, a large elongation break, low-temperature resistance, and a low long-term deformation rate. TPU fabrics keep materials flexible and soft. These characteristics produce technical textiles that withstand extensive wear and environmental stressors. TPU-coated textiles resist UV rays, abrasions, and punctures. With glued or welded seals, these fabrics are air- and liquid-tight.

    Sheet waterproofing membrane

    As the name suggests, these are rolled membranes. Unfurl them and lay them flat. Bituminous waterproofing membranes are most common. This membrane is adhered with a hot tar-based adhesive using blowtorches.

    Hot adhesive joins adjacent membranes. The sheets are overlapped by 100mm (4"). Some membranes are melted with a hot air gun and overlapped on the previous sheet. This membrane's sheet joints must be perfect to prevent leaks.

    PVC waterproofing membrane

    The polyvinyl-chloride (PVC) waterproofing volume material is high-performance and high-quality. It joins processing assistants such as plasticiser, anti-ultraviolet ray medicinal preparation, anti-aged medicinal preparation, and stabilizer after the PVC resin to form a high polymer waterproofing volume material. Because this product uses a unique formula, its life far exceeds that of general waterproofing materials, and the entire waterproofing system has a long lifespan. The roofing lasts 30 years, and the underground lasts 50 years.

    The PVC waterproofing membrane is made of high-quality flexible polyvinyl chloride. There are reinforced and unreinforced membranes based on application. Reinforced waterproofing membrane uses polyester mesh or glass fiber to waterproof roofs. Durable reinforced membranes. Flexible, tear-resistant unreinforced membranes are used to waterproof underground structures, tunnels, and pools. PVC waterproofing membrane is vapour-permeable. This allows moisture to escape from the building's roof.

    Liquid applied membranes

    Liquid membranes are sprayed or brushed on and cure in the air to form a seamless, joint-free membrane. More liquid chemical per unit area controls thickness. Due to the quick application, a contractor will try to waterproof the entire area in one day to avoid cold joints. If a large area must be done over several days, cold joints can be easily made by overlapping the new membrane over the old. The chemical will stick to itself.

    Joint-free membranes are superior to sheet-based membranes. Applying the right thickness requires care. Too-thin membranes tear or break. Good membrane-to-concrete adhesion is required. Sand-broadcasting roughens a waterproofing membrane before applying a concrete screed. This is throwing a thin layer of sand by hand over a wet membrane (before it has set) so the sand sticks to the membrane and provides a rough surface for concrete.

    Different Waterproofing Methods

    What are the ideal waterproofing materials for a venue? To give a solid answer to this question, we need to take a closer look at the waterproofing materials.

    Cement Based Waterproofing Method

    Cement-based waterproofing is the easiest in construction. Cement-based waterproofing materials are easy to mix and apply.

    This is common in bathrooms and toilets. This method waterproofs completely or partially. It's used in dark or rainy places.

    Liquid Waterproofing Membrane Method

    Ideal water insulation materials and liquid water insulation methods are the answers. The liquid waterproofing membrane method is a thin coating applied by spray, roller, or trowel. Cement-based waterproofing is less flexible. Today, it's used more.

    How to use liquid waterproofing membrane? The coating has 2000% elongation. Liquid waterproofing's durability depends on the polymer used.

    The liquid waterproofing membrane may be polymer-modified asphalt. Manufacturers offer acrylic, hybrid, or polyurethane liquid membranes for trowel, roller, or spray.

    Bituminous Coating Waterproofing Method

    Bituminous coating is formulated and polymerized to be waterproof and flexible. Polymer class and fiber reinforcement affect its flexibility and water resistance.

    Asphalt coating is bituminous. Bituminous coatings are commonly used under screed. It protects and waterproofs concrete foundations.

    Bitumen-based coating isn't suitable for sun exposure. When exposed to sunlight for a long time, it becomes fragile unless modified with polyurethane or acrylic-based polymers.

    The finished product's flexibility depends on the polymer's solids content.

    Bitumen Membrane Waterproofing Method

    Bituminous membrane waterproofing is a popular method for low-slope roofs. Self-adhesive bituminous waterproofing membrane.

    To improve adhesion, resins and oils may be added to self-adhesive compounds, asphalt, polymer, and filler. Self-adhesive membranes lose adhesion over time, reducing their shelf life.

    Polyurethane Liquid Membrane Waterproofing Method

    Flat roofs exposed to weather are waterproofed with polyurethane liquid membrane. This waterproofing method is costly.

    Flexible Polyurethane Liquid Membrane. Polyurethane is sensitive to moisture, so it must be carefully evaluated before application. Membranes may peel or bond otherwise.

    Waterproofing materials vary. Effectiveness varies. Not all of them are equal. You must invest time and effort to determine which one suits your individual project needs. You must research these materials to determine which is best for your application. You learned more above. Find the best one for your home.

    FAQs About Waterproofing

    If the ceramic tile is already installed there is no way to fully waterproof the floor after the fact, unless you replace the tile and install a legitimate waterproof membrane during the replacement process.

    If you see any water, dribbles or leaks, or if you feel any dampness, then you need to get your basement waterproofed. Waiting will only worsen the damage and make the issues more expensive. New home ownership can be daunting, but it's important to address problems before they become catastrophes.

    If the waterproof membrane was applied using an adhesive, a blowtorch may be required to melt the adhesive enough for it to be removed. After this is done, a good scraping or blast from a compressor will remove any leftover residue.

    Floors, shower enclosures and areas around the toilet and bath need to be thoroughly sealed, but the walls and ceilings do not need to be comprehensively waterproofed. As long as you use paint that can withstand moisture and steam, you can paint your walls and install some of your fixtures.

    The length of time waterproofing lasts depends on a few different factors including the amount of waterproofing product used, climate, and the severity of the initial damage. With all the different constituents, there's no set date, but most professionals will warranty it for about ten years.
