Epoxy Injection
This method of repair is often used in conjunction with other repairs. Epoxy injection will bond concrete together at a crack, but it doesn’t address problems outside of the immediate area of the crack. This method is usually used where only minor settling has occurred and future settling is not expected.
How it’s done
The crack will be thoroughly cleaned. The surface of the crack is then sealed and injection ports placed along he crack. Epoxy in then injected into the crack under pressure to ensure the entire crack is filled. The repaired area will then be ground down to a smooth surface.
Grade Beams
A grade beam is in effect a deepened foundation placed under your existing foundation. This procedure works well when a sufficiently bearing soil is not far below your existing foundation .
How it’s done
Your structure is temporarily supported to allow for excavation under your existing footing. An excavation is made with its size dependent on your structure and existing soil conditions. The new grade beam is then attached to your existing foundation creating one larger foundation.
Caissons
Caissons are large diameter holes that are dug through poor soil into inadequate bearing soil. This allows a home’s foundation to rest on the deeper soil and bypass the problem soil. This is a common repair on hillsides and cut and fill construction areas.
How it’s done
A drill rig is brought in and holes are dug to a depth as determined by engineering and soils reports. Hole depths can range from just a few feet to 20′ and beyond. Caissons are filled with concrete, attached to the grade beam which your structure is then resting on.
