Can you raise and level your own concrete? Occasionally someone balks at our minimum job charge of three hundred dollars. I understand, particularly when the concrete slab is very small, for example a small slab just outside a garage man door. They are often just 3×3 but for some reason prone to settling. If you...
Concrete leveling, mud or foam? Whether it be called foam jacking, PolyLEVEL, polylift, or Geo-polymer, polyurethane has many advantages over mud for lifting concrete. Having experience with both Mudjacking and Geo-polymer injection Slabjacking let’s briefly compare the two. Mudjacking advantages – material is less costly, point load lifting is less complex, the equipment is simpler....
Voids, Hollows, Caverns, Dens….are you dealing with void space under your concrete? One of the advantages of using Geo-polymer for filling voids is its light weight. Various formulations can be ordered but our polymer of choice is HMI’s RR401g. For large void fill jobs lighter duty polymers can be a very cost-effective alternative to gravel...
Slab curl is something that can happen along control joints and edges as they cure. The differential in humidity and temperature causes slabs to curl up or down but generally up as the soil keeps the underside cooler and wetter. In residential concrete this isn’t as big of a concern but in warehouses where fork...

We got a call from a homeowner that their fifty year old home was experiencing some settling on a porch and some attached...
Concrete porch settling? Settled concrete porches are a fairly common thing to see but not as easy to properly repair. A simple concrete porch may weigh many tons, have unseen sub grade supports, may be the base for both decorative pillars and structural support for overhead eves and more. Because of this it is important...
What is Mudjacking? Slabjacking, foam jacking, mudjacking, Polylevel ™ sand jacking, what’s in a name? Mudjacking is a process that hydraulically raises concrete slabs. Until fairly recently, it was the only method available other than replacement. Holes ranging in size from 1 inch to 2 1/2 inches in diameter are drilled and a grout pump...
