Polyurethane Injection Technology

What is slabjacking?



The first step in slabjacking involves drilling small diameter access holes in the concrete slab.


Once the holes are drilled, a specialty grout is injected through the concrete, ultimately lifting it from below.


The access holes are patched with a fast-setting cement once the lifting work is complete.

Slabjacking is a method of lifting settled concrete. The process is also commonly referred to as mudjacking, polyjacking, and pressure grouting. In essence, slabjacking involves drilling small holes through a concrete slab.  A specialty grout is then pumped through the concrete, effectively lifting it from below.  

Traditional concrete replacement methods consist of a 'rip and replace', which is a complete tear out and replacement of the sunken concrete slabs. Construction can greatly impact any existing operations at the job site. This is especially realized when the settling concrete is occupied by an existing business. In some cases, the business has to be relocated or shut down to accommodate a 'rip and replace'.

High density polyurethane foam is now revolutionizing the effectiveness of concrete slabjacking . It provides all the same advantages of traditional slabjacking with new and improved features.   Clients greatly benefit from the smaller injection holes, which are about the size of a common penny. 

The slabjacking process can be done for:
