Filling Gap Between Concrete Slab And Wall

So filling them should be a maintenance priority.

Filling gap between concrete slab and wall.

I m trying to determine whether to caulk the crack or fill it with some cement based patching. Foam backer rods act to fill in space between concrete joints so you don t need to use a ton of self leveling sealant. Gaps can occur between asphalt and concrete for many reasons including weather changes vehicle inflicted damage or improper installation of the asphalt. There s a wide ugly gap between my concrete outdoor patio slab and the slab my house is built on.

The sashco slab sealant is one of the best concrete crack repair sealants you can buy. Typically this will be cracks in your foundation. The gap in question was previously filled with either fiberboard or concrete crack sealant but enough of it has deteriorated to conceivably allow moisture in. The screed and concrete around the edge of my concrete slab where the slab meets the external cavity wall was cracked.

If water seeps between the gap in the asphalt and a house foundation water can erode the foundation and cause serious structural problems for the house. It s maybe 1 8 to 1 4 of an inch below your slabs. This will hopefully be the fix that keeps that wall of the sunroom nice and dry. Gaps in concrete whether they result from cracks in the slab or occur between the slab and an adjacent surface can serve as openings that allow dirt moisture or insects into your home.

While the sashco slab is a bit on the expensive end it s completely worth it. I poked at it with a chisel and removed the loose material. This has left a channel of about 1 wide all the way around the edge of the wall. To remedy this issue i installed backer rod in the gap that i then covered with concrete crack sealant.

The straight line gaps between the slabs has enlarged and some cracks are as wide as 2 inches. In the short term a sealant applied along this gap between your basement floor and wall may prevent leakage. The driveway slopes down from my garage to the street. It doesn t allow moisture to seep through the crack which increases the lifespan of the concrete surface.

Then you can fill in the gap using sika flex self leveling sealant. The water being blocked by the sealant will find another gap in your foundation to enter the home. It delivers high quality concrete adhesion and keeps cracks sealed. There s no need to pay a contractor however.
