Terraces and roofs are directly exposed to extreme weather conditions and can cause leaks if not protected properly. Charan Techno Chem offer waterproofing solutions for terraces, balconies and both flat and sloping roofs, to keep your factory / house safe from leaks during monsoons & also indirectly protect the reinforcement in the RCC slab from corrosion due to moisture.

Roof/Terrace Area-Waterproofing of any terrace area in general is very complex as it is exposed to variable weather conditions, foot traffic etc. It is often the leakage through the terrace that causes severe dampness in the ceilings, thus spoiling the look of expensive interiors and also leading to weakening of the roof slab and concrete. Critical parameters impacting selection of the material is based on the following:-

Recommended solution by Charan Techno Chem for under coat systems- Polyurethane coating system– There are 2 types

• Pitch modified PU –Pitch is a resin such as bitumen, coal tar etc. which when combined with PU forms such a system. These systems are used as an under coat in case of large span areas, they have high elongation and are very tough.
• Pure PU

Prior to application of these systems, the surface must be clean and sound as per checklist i.e. all joints, honeycombs and hollowness must be packed with Polymer Modified Mortar.

Top coat systems-These coating are UV Stable and can be exposed to light/mild foot traffic. In some cases, they are also used as a heat reflective coat depending on the color and SRI Value. It is further divided depending on the base material used

• Polymer based systems- Single component acrylic coating systems form a part of this category, these coating are elastomeric, flexible, tough and can be left exposed. Also they can be subjected to light foot traffic.
• Hybrid PU-These systems are a combination of PU and acrylic compounds to form a tough coating. Surface must be in SSD state.
