ROOF WATERPROOFING

Roofs are the most exposed areas of a structure, especially in extreme weather conditions. The absence or inadequate waterproofing in these areas can lead to severe problems like leakages in cuttings and dampness in the parapet. The continuous exposure to climatic changes can cause wear and tear of the roof which in turn causes leakage and damage. Thus, it is important to avoid cracks in slab and waterproof it to prevent these problems. Furthermore, if there is a leaking tank on the top, it will be like adding salt to the wound.

Crack: RCC shrinks over a period of time causing crack in the roof. This paves a way for water infiltration into the structure.

Slope of the Roof: Leakage persists when there is not a proper slope for water drainage. A flat RCC slab laid to slope of 1 in 40 is good enough to drain the entire rainwater for regions with normal rainfall and 1 in 20 for regions with heavy rainfall.

Improper Maintenance: Improper maintenance can lead to water infiltration. Since water can’t run off, it seeps into the surface.

Cementitious

Cementitious membranes are used for waterproofing wet rooms , water tanks and for exterior surface protection. For more durability and life span, it needs a protective coating. These products are probably easiest waterproofing materials to use. These coatings have good bonding to concrete and masonry due to their cementitious nature. POLYBOND, MAGNOFIX are the main products used for coating. They can also be used as primers. Above and beyond using it as a primer, MAGNOFIX can also be used to create decorative items like pots, fish tanks, flower vases etc…

Acrylic

This one is better than cementitious water proofing. It can be used in toilets, sunken portions, roofs, swimming pools, water tanks, asbestos roofs, terraces etc. These acrylics add waterproofing characteristics and properties to in-place materials. It has excellent adhesion to plastered cement and previously painted surfaces. FLEXCOAT 2K, DAMCOAT are our main products. They can be used on surfaces where sun exposure and weathering is low.

Polyurethane

This is the most expensive and latest technique. Out of the three, polyurethane is the best option. It is a polyurethane layer applied to the surface to prevent leakage and moisture infiltration and thereby protecting the surface from corrosion, weathering and other deteriorating processes. It is a single component modified polyurethane liquid applied coating that is composed of specially developed polymers. PU has excellent flexibility and bonding with concrete, breathing properties, water resistance, crack bridging properties and weathering durability.
