The March quarter shows volumes running at 917,314 m3 but this is actually the second quarter running that volumes have declined. Sand is filled at a height of 0.15m and then Sand level … An expansion joint is provided between concrete slab and wall to relieve the stress during high-temperature days. The perimeter of the Grade slab is thicker than the rest of surface, this thicker section acts as a mini footing and helps to distribute top loads more evenly across the surrounding soil. Before it is built, contractors will excavate the soil surrounding the area the foundation is to be built and make sure that the ground is stable enough to support the structure. Light loads.
