Basement Waterproofing Photo Album: Seal wall crack in caledonia, On

Lindsay & Graham in Caledonia noticed water at the base of their poured concrete wall and showing water signs on the floor. after opening up the insulation, they found that a previous repair by another waterproofing company had failed and was leaking. The previous company used the injection method and this type is prone to failure because it becomes brittle and re-cracks from the hot and cold cycles of the year. Omni basement Systems installed the patented Flexispan wall crack repair. Flexispan stays flexible for the life of the home and no amount of wall movement can make it re-leak.

Finished product

The wall membranes are in place and the floor has been restored.

previous repair

This type of repair is less expensive but it only lasts 5-10 years at the most.

remove old repair

`First step in this case is to remove the old repair by grinding down the wall.

Opening the floor

The crack does ot stop at the floor . In fact it goes all the way to the footing. We open the floor and expose the footing and the gravel bed below.

Flexible Sealant

We then put a flexible sealant into the crack. This is the first line of defense for the leaking crack.

open cell drainage foam

Over the bead of sealant, an open cell drainage foam is applied. IF any moisture ever gets past the sealant, this is used as second line of defense to direct it down to the gravel bed beneath the floor slab.
