What is slabjacking?
	Slabjacking is defined as "grout pumped under pressure through small holes (1.5 inch diameter) to raise faulty or sunken concrete". The holes are strategically placed to ensure proper lift. Our exclusive non-shrink cement grout is pumped under the sunken concrete at the rate of 1 cubic foot per minute. This completely fills any voids, and raises the concrete to it's original height. After the lifting is complete, we clean the area of excess drill tailings and grout, then re-cement the holes with our custom color matching system. Most work is completed in less than 4 hours.
