Waterproofing concrete with roof reinforcement is an important task on concrete structures for roof repair and preservation. Many roofs throughout the world are constructed using poured concrete. These structures are usually made with reinforced steel. They are inexpensive but require a great deal of maintenance to keep them from leaking since they shift, move, and dissolve easily. Concrete is made up from several ingredients including calcium carbonate and sand. Calcium Carbonate is a plentiful substance that comes from the dead skeletons of sea life. These plentiful substances dissolve quite easily in very wet environments unless they are protected.

Unprotected concrete cracks and dissolves in many areas where there are heavy rains. During winter, water leaks into the unprotected cracks and freezes which expand substantially further damaging your concrete building. Mandhana Polymers Pvt Ltd. Company specializes in the making of specialty plastic TPO sheet that extend the life of these concrete roofs. These TPO sheets Prevent water from seeping by forming a waterproof membrane.

Mandhana sheets are made to take care of your roof waterproofing requirements in any weather conditions. Also enlisted are the features of Mandhana sheets that clearly state the advantages over the existing methods of water proofing procedures which have a limited life period.

Surface
Preparation
Just sweeping of debries and
other removable items.
Power washing of the surface area of the roof to remove most of the loose material. Use caution, so as not to damage any interior areas due to roof leakage that are inside the building. You may need to roughen the Surface. Any large cracks and crevices needs to be filled with cement and other materials.
