Pressure Grouting



The tower foundation was severely cracked. With Hurricane Irene oncoming, emergency repairs were performed to repair the concrete foundation. Pressure grouting was utilized to repair the concrete.

Pressure grouting involves the injection of a grout into either a substrate or an existing structure.  The process is done for various results, mostly involving structural improvement of some sort. 

Pressure grouting applications include:

Concrete Crack Repair: Epoxy and polyurethane grouts are commonly injected into concrete cracks for structural repair and waterproofing applications.  Portable equipment can be utilized to pressure grout most concrete repair projects. 

Slabjacking: Pressure grouting sometimes refers to the slabjacking process.   Traditionally, concrete can be lifted through the strategic injections of a pressurized grout.   

Compaction Grouting: Cement and urethane grouts can be injected into soil deposits for structural improvement and water control applications.   Dams and levee's can also greatly benefit from permeation grouting work.

Void Filling:  Soil settlement can leave void spaces underneath concrete structures.  EFT provides specialty urethane foam injections for void filling applications. 

Slipline Grouting:  Trenchless pipe rehabilitation sometimes requires annulus/void space to be pressure grouted for structural improvement of the pipe system.
