Grout can either be pumped through holes drilled in the concrete, or be injected by digging a small access hole adjacent to the affected area and injecting material in from the side.  The condition and size of the affected area and also of the surrounding area dictates which method works best. 

If grout is pumped through access holes, Concrete Jack will patch the holes with a color-matching grout material.  Have exposed aggregate?  Not a problem; Concrete Jack can patch exposed aggregate, too.  If grout is pumped through an access area to the side of the affected area, Concrete Jack will restore the area to its original condition, at no extra cost.

1-5/8" holes are drilled through the affected area.


Grout is pumped into the holes to fill the void and lift the concrete.


After the area has been lifted, holes are patched to match the existing concrete.
