WATERPROOFING SERVICE FOR BASEMENTS | UNDERGROUND STRUCTURES

Marvel WaterProofing Service in Chennai – Terrace is the most crucial segment of a building, and it is exposed to direct climatic variations, extremes of rainfall and structural movements caused thereby. So every effort should be taken at the design stage itself to ensure that a proper protection system has been incorporated. It has often been found that the economic solution is not always the best solution. So, the system, which assures maximum protection, should be selected even though it may cost little more.

CEMENTITIOUS WATERPROOFING SERVICE

Flexible cementitious waterproofing membranes comprise a mix of dry cement and sand, and liquid latex. The materials are mixed on construction sites resulting in a relatively thin, cementitious liquid that can be applied by brush or roller onto different substrates.
Whilst it’s down to the cementitious materials to bring tensile strength, it’s the liquid latex that provides flexibility and waterproofing in the system. Flexibility is particularly important in terms of providing bridges over cracks in the substrate. The typical ratio of polymer to cement (based on dry weight) for both products is between 40% and 100% i.e. 80% to 200% liquid latex.

LIQUID WATERPROOFING MEMBRANE

Liquid membrane is a thin coating which consists of usually a primer coat and two coats of top coats which are applied by spray, roller, or trowel. It offers more flexibility than the cementitious types of waterproofing. The liquid cures into a rubbery coating on the wall. The elongation properties of the coating can reach as high as 280%. Liquid waterproofing membrane is available in the form of liquid and is sprayed or applied by brush or roller to the concrete surface which forms a thick joint free membrane in contact with air.

BITUMINOUS COATING WATERPROOFING SERVICE

Bitumen is modified using different substances like natural rubber or styrene to make it more resistant to fatigue brought about by movement failure. Two or more bitumen solution layers can be applied for maximum effect. A bitumen liquid roof coating can serve for between 10 to 20 years. It is an excellent protective coating and waterproofing agent, especially on surfaces such as concrete foundations. Bituminous coating is made of bitumen based materials and it is not suitable for expose to sunlight. It becomes very brittle and fragile when long exposure to the sunlight unless it is modified with more flexible material such as polyurethane or acrylic based polymers.

MEMBRANE WATERPROOFING SERVICE

Membrane waterproofing is a popular method used for low-sloped roofs due to their proven performance. Waterproofing membrane have torch on membrane and self-adhesive membrane.Torch on membrane have exposed and covered types. Exposed membrane often has mineral granular aggregate to withstand the wear and tear of the weathering and the other types of membrane, contractor need to apply one protective screed to prevent the puncture of the membrane.

POLYURETHANE LIQUID MEMBRANE WATERPROOFING SERVICE

Polyurethane Liquid Membrane can offer higher flexibility. Polyurethane is very sensitive to moisture content present, therefore before application, one has to be very careful evaluating the moisture content of the concrete slab, otherwise peeling or de-bonding of membranes may happen after some time.

WATERPROOFING FIBERGLASS MESH

Waterproofing mesh is used as reinforcement for waterproofing for terrace, bathroom, Basement etc and used for Decorative tiles as support to hold the tiles. It is used after surface treatment, the fibre glass mesh have excellent properties inculding water resistance, alkali resistance, flexibility, softness and resistance to aging.
The products are widely used in wall enhancement, wall thermal insulation, waterproofing and various fiberglass wares such as polyphenyl boards, anti-corrosive boards, heated. This product is very durable, versatile and cost effective.
