Before installing, we ensure that the area where waterproofing system needs to be install shall made free from all other activities that could disrupt the installation of the system. We also inspect and ensure that the substrates are free of cracks, broken sheets, damage etc. We carry out all the necessary rectification and preparatory works before the installation of the specified waterproofing system. The methodology, which we commonly followed for doing waterproofing job are as under:
Cleaning and removing of loosely adhering particles with soft/wire brush/blower application and made free from any other contaminants (if any).
All overlapping joints, corner joints between metal to concrete structure or brick masonry shall be specially sealed with flexible and compatible systems.
Choice of waterproofing systems is depends on various aspects such as requirement of site, locations, applicability of products, flexible to movement, durability and combination of layers etc.
For better strength and reinforcement to waterproofing layers it is recommend that a suitable woven fiber mesh of 45-60 GSM shall be placed between the layers.
