Trench is opened

A flexible sealant is troweled over the first three layers. to the very bottom of the crack.
When the process is finished, the concrete is restored and the insulation is taped back again.
Long Wall crack
The most common area for basement wall cracks is at the corner of a window. This crack did not go straight down but it went on a 45-degree angle to the corner of the building

Omni Basement Systems uses their own Cleanspace membrane to cover the entire area. At the bottom, a drainage membrane is used to go over the footing to direct any moisture into the gravel bed.
