Concrete cracks, every concrete contractor will tell you the same thing, live with it. It is frustrating, can anything be done? Concealing cracks is not always something that can be done completely. There are several materials to fill cracks both cheap and expensive. Can anything be done to better conceal cracks? We have found staining...

Heaved concrete
Some of the communities we serve have an abundance of concrete that is heaved, primarily by roots. What can be done? There are really just two approaches to this problem other than ignoring and accepting liability. -We can raise adjacent slabs to create a transition up and over the root, in effect a ramp. This...

Slabjack Geotechnical – how much can you lift?
Occasionally we’re asked how heavy of a structure we can lift. Geo-polymers Slabjacking has raised structures well over a quarter million pounds. It is actually quite surprising how much a concrete structure will weigh. Entry porches are a good example of this and can be instructive of why they settle. A six-foot deep porch...

Slabjack Geotechnical minimum job charge
How much does Slabjacking, mudjacking, Polylevel concrete leveling cost? Occasionally we are asked about doing a very small job, for example off a garage man door, often these are very small 3×3 slabs. Or we asked about our “minimum” job charge. We have a $500 minimum job charge. $500 will raise one hundred fifty square...

Slabjacking – Polymer vs Mud
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...
Leveling a settled concrete warehouse floor. We saved Bluebird packers a truckload of money on a job we did for them this last year. One of their C/A storage rooms had a section that had settled, after pulling level lines across the floor we found about two and a half inches of total settlement. Because...
Poor compaction coupled with excess water causes virtually all the settled concrete we see. Recently the drastic effect of excess water was demonstrated on a home where compaction was not an issue. 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...
