Gerald W. in Burlington called and said he was concerned about horizontal cracks in his block foundation walls.
The timing for his call couldn't be better because if he has left it any longer it would have gotten worse and required a lot more work with more expensive procedure. Omni Basement system with products of Supportworks designed a system to stabilize the block walls from bowing any more.
Omni Basement Systems adhered 7" wide strips of carbon fibre called Carbon Armour to the wall with Epoxy. The stprips were also attached to the rim joist using Armour locks from Supportworks. Teis system ties the wall into the floor joist system of the house for added support to the wall. The last proccess is to solidify the bottom 3 courses of block by filling the cavities with fibreglass infused grout.
