What is Geo-polymer Injection?

What's best, Geo-Polymer Injection or Mudjacking? 

While mudjacking is a perfectly acceptable method of raising concrete, it has several shortcomings. Read on for detailed information on major differences between the two......


Holes drilled are about the size of a dime, only 5/8", and are placed about three to four feet apart.

You will have far fewer holes and the size of those holes in most cases is one fourth as large. You will have a hard time even seeing where we drilled into your slab as we match color, tint and texture.

Slabjack Geotechnical uses a fully Hydrophobic Geo-Polymer, a large word meaning "not effected by water" Unlike mud, it can't wash out, rodents won't burrow in it, and here is the really cool part, it is capable of setting up in fully saturated soil.


If you have a sea wall that needs sealing, if you have slabs on saturated soils, this is the only way to solve your problem. Additionally, the polymer we use, RR401G, is twice as dense as many of the polymers on the market today which allows us to raise structures others are not capable of raising. While this polymer is very dense it weighs only four pounds per cubic foot so it doesn't further burden already overburdened soils.

Geo-Polymer Slabjacking is generally a very sanitary operation. We do work indoors at warehouses, plants, offices and residences without dust, mud or the hassles of clean up with a garden hose that mudjacking requires. Just a simple three step operation;

Drill, Inject, Patch.



The holes needed to pump a mud slurry through a hose range in size from a minimum of 1" all the way up to 2" in diameter, that's a big hole to try to conceal.

Those big holes weaken and can crack the slab if drilled to near an edge.

Mud does not flow under a slab very far which requires holes to be fairly close together, typically every two feet. If you have a large concrete slab you will have a number of patched holes detracting from the appearance of the finished product and looking a bit like Swiss cheese!

Mud or concrete slurry is heavy, between 100 and 140lbs per cubic foot. All settled concrete has one thing in common the ground cannot support the weight of the concrete already there, pumping additional weight under a slab can cause further settling.

Mudjacking is a messy operation requiring hosing off the slab when work is completed, not easy to do on interior work or garages or in warehouses or offices.

Bottom Line, Slabjack Geotechnical's Geo-Polymer Injection is far superior to traditional mudjacking.
