Expansion joint gaps neglected during the design process, joints are not treated well, they cannot handle the thermal expansion due to the changing seasons, ultimately leaving a leak point in the structure.
A Concrete Expansion joint is a gap which allows the Concrete to expand and contract as/when the temperature changes. It forms a break between the concrete and other parts of a structure to allow movement without causing stress, which can lead to cracking.
Shourya waterproofing keeps the joints watertight to prevent moisture from seeping under concrete pads and causing them to heave or sink. The Main purpose of a concrete expansion joint treatment is to allow the pads to expand and contract (get bigger and smaller) with temperature & humidity changes.
