Using concrete motor to fill gaps in a basement wall.
Snip the opening of the tube at a 30 degree angle making the opening the same size as your gap.

The ergonomically designed filler easily reaches into narrow cracks and saturates the space created by the crack.
This liquid cement or concrete crack filler is ideal for narrow cracks on the deck in the basement etc.
You don t have to bother about proportioning or mixing as this liquid cement crack filler is ready to use.
Fill the crack with urethane caulk similar to what you would use for driveway caulk.
Stuff the rod into the gap filling it up to about 1 4 inch from the surface of the concrete.
Use a smooth even motion filling the crack flush with the surface beveling it if it s against the house.
The water being blocked by the sealant will find another gap in your foundation to enter the home.
Even so the new concrete does not bond with the already cured footings so a tiny gap exists between the two.
Use the end of a putty knife to push the rod firmly into the gap.
In the short term a sealant applied along this gap between your basement floor and wall may prevent leakage.
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.
It works perfectly as a concrete expansion joint sealant.
