Seal Gap Between Concrete Floor And Wall
This will hopefully be the fix that keeps that wall of the sunroom nice and dry.
Seal gap between concrete floor and wall. However it s not that simple. Remove the baseboard if present to expose the gap between the subfloor and the wall face. Fill the crack with urethane caulk similar to what you would use for driveway caulk. Slide the flat end of a pry bar between the baseboard and the wall.
It works perfectly as a concrete expansion joint sealant. Even so the new concrete does not bond with the already cured footings so a tiny gap exists between the two. After the walls have cured the basement floor is poured leaving a similar tiny gap known as the cove joint between the cured walls and newly poured floor. Use a smooth even motion filling the crack flush with the surface beveling it if it s against the house.
Snip the opening of the tube at a 30 degree angle making the opening the same size as your gap. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant. Under ordinary circumstances this gap is too small to admit water. However it will eventually fail in one of two ways.
Typically this will be cracks in your foundation.
