Rubber Waterproofing Membrane For Terrace

There are many times of waterproofing products & systems such as Sheet Applied Membranes Waterproofing, Liquid Waterproofing Membrane, crystalline systems, etc., available in the market for Terrace waterproofing. But not all are equal and it’s essential to carefully analyze the advantages and disadvantages of each product/system before it is considered to be adopted. Selection of a wrong type of waterproofing could lead to major problems.

Terrace is the last highest level of building and faces extreme heat, cold, rain and other climatic conditions. Building roof can be of either RCC slab, pre-cast panels, Metal decks, Glass fibers sheets, etc. Some Architects even go for terrace gardens for architectural views.

Structure terrace area, if it is already facing the water leakage problem because of developed cracks, then it is very difficult to treatment the problematic area, or doing rectifications. If the structure is old, then breaking, removing, cut opening the damaged or weak surface, process weaken structural integrity. In waterproofing of large structural area like, landscape-podium area or large terrace area, movement of the structure is expected. In all these scenarios, rubber membrane is best waterproofing membrane. These membranes are best membrane to precast panel building as the membrane is tough and strong to bridge and accommodate the building panel movement, without membrane tearing. Rubber membranes can also be used in lining of various artificial water bodies such as canals, reservoirs, artificial lakes, fish hatcheries, etc.,
