The thin layer of watertight material that’s laid above the roofing slab and below the finish tiles is the waterproofing membrane. Look for trusted suppliers on WorldBuild365 – the online directory of waterproofing membrane manufacturers, damp proof membrane manufacturers, and PVC membrane manufacturers.
These membranes need to be:
Of high quality for flexibility and durability.
Strong enough to ensure a long service life.
Resistant to precipitation.
Membranes and Sheets
A complete range is available from the waterproofing membrane suppliers you'll find in this directory:
Waterproofing sheets are designed to have superior resistance from extremes in temperature, and against acidic and alkaline chemicals. This type of waterproofing system is very effective in preventing the passage of water and water vapor, as they’re specially reinforced with polyester spunbond and coated with polyethylene film. Sheets can be used for basement tanking, and damp proofing.
Homogeneous PVC waterproofing membrane is suitable for applying to drinking water and other water tanks as it’s vapor permeable without reinforcement. It can also be used as a top layer for water channels. The light weight makes for fast and easy installation, giving adaptability as well as the required protection.
PVC waterproofing membrane is classified into three categories: smooth, fiber fleece back, and reinforced. Only waterproofing membrane manufacturers with the latest formulation of UV-resistant polyvinyl chloride resin provide this option. It's combined with filing and auxiliary agents, molded together by high-end technology, and delivers a pliable and durable sheet. This reinforced construction enhances the tensile and tear strength.
Waterproofing layers are covers designed to create appropriate solutions for every kind of roof and walling system. The vapor permeability feature prevents air flow coming in through the walls, and allows water vapor to escape from inside. Buildings are protected from water accumulation, potential condensation, and mold formation.
Cement, Liquid Rubber and Polymers
Added extras to seal and protect.
Waterproofing cement is water resistant cement suitable for outdoor use – it’s environmentally friendly and safe. Ideal for filling potholes, cracks, and crevices, this cement mixture is ready to use. Add water, and apply to a previously prepared and cleaned surface. The texture makes it suitable for water tanks, swimming pools, and other water-related projects.
Cement-based brushable sealing slurry is ideal for flexibility when a waterproofing layer is needed, as on a roof or in the bathroom. This product is classified as a coating for the surface protection of concrete, and is a one-component, fiber-enforced, polymer-modified sealing slurry. Use for waterproofing plaster, bricks, and cement blocks. You'll also find two-component flexible brushable sealing slurry on this site.
Polymers are liquid pigmented, wear resistant, and semi-rigid components. The reaction with ground and air humidity causes them to harden. Used for roof waterproofing, balconies, terraces, and verandas, as well as for decks and walkways. Liquid applied elastic polyurethane polymers are elastic to repel the cold, and are used for long-lasting roof waterproofing.
Waterstops are used for waterproofing cold and expansion joints. They reduce the stress on the structure caused by temperature fluctuations and uneven ground subsidence. Cold and water resistance are heightened, and the appearance of the structure improved. The waterstops are manufactured in 20m rolls.
Liquid rubber is designed for waterproofing and corrosion protection of concrete, brick, and metal structures. The bitumen-polymer emulsion is hardened with a crystalline powder, giving it the ability to adhere to any base material. It forms a seamless, highly elastic, rubber-like waterproof coating, and complies with all roofing and waterproofing specifications - it’s also environmentally safe. Also available is liquid rubber single component.

Coating waterproofing is specifically for use at very low temperatures. The material doesn’t flow, and so is ideal for vertical surface work. It has a high level of adhesion to concrete, metal, and wood, and is easy to apply. Low water absorption is also another feature.
Penetrating waterproofing is used for concrete and reinforced concrete structures, and for isolating waterproofing in brickwork. The waterproofing effect is achieved by the filling of voids and pores with water insoluble compounds that are produced by the reaction of the chemical additives to the cement stone phases. Advantages include resistance to corrosion, retention of vapor and air permeability, and long lasting waterproof qualities.
Seam waterproofing is perfect for waterproofing cracks, molding joints, pipes, seams, and connections. It has high water impermeability, doesn’t shrink, and is resistant to thermal and mechanical deformations. It can be used under intensive water pressure, and complies with all dry building mixtures recommendations.
