House Constuction [Merged]

That's fine if you don't need to store anything that should be kept dry under. Though they look to seek no upkeep, the sublayer concrete is hygroscopic & requires thorough watertightening/sealing(periodic)....Molds & roaches love the dark & damp spaces below those tiled counters.

Bai is there a sealant preferably in a spray can that I can use to seal this concrete? Our sink is sandwiched between a concrete slab and granite top and there seems to be a gap that lets water through from the edges.

There should be a gap between top & concrete....use nothing less than Polyurethane Seal(not silicone). Preparation is key. Area should be clean of grease/dirt & dry prior to application. Sika, Bostik, even Pioneer now have em. Cure time must properly be observed. Liquid, i.e. Thompson's, won't likely work.

How much would it cost to change a pivoting door with a sliding door? Is this allowed in condos?
