Foundation Repair

Problem: Grout doesn't pump into hole, or squirts back out.

Solution: Blow out the hole with air or drill further into the sub-base.

Problem: New cracks form or old ones are enlarged.

Solution: Usually a problem with technique: pumping too much grout into one hole, using grout that is too stiff, or pumping holes in the wrong sequence. Rule of thumb: don't lift a slab more tha an inch while pumping at one hole.

Problem: Slab lifts in wrong place.

Solution: The grout may be too thin. Leave the hole for a while, and come back with a thicker grout.

Problem: Slab binds against concrete and won't rise.

Solution: Grout may be flowing beneath an adjoining slab, use a thicker grout. You can also relieve binding by chipping concrete the edge of the slab, sawing a relief slot all the way through the slab, make sure joints and cracks are clean before starting to pump grout.

Problem: Grout leaks through cracks or joints at the side of the slab.

Solution: Let it set up, then resume normal pumping. Leaks at the slab edge can be stopped by using a thicker grout.
