Chemical Grout Injection

Chemical Grout Injection is a process of injecting a near water-viscosity liquid under low pressure, into cohesionless soil to create a solid stonelike mass.

When loose soils in the top 10 feet beneath your foundation need consolidation, pressure grouting with a concrete mixture cannot be used due to the high possibility of heaving your structure. A chemical injection formula would be chosen by your Geological Engineer to be pumped under low pressure into the loose soils.

This procedure is often used around pool decks and other high-pressure sensitive areas where cement based grout could be detrimental.

On projects where needed, Secure Foundation Systems, Inc. can provide support for excavated walls, prevent surface ground settlement, control erosion, reduce liquefaction potential, and create a chemical stonelike anchor for various size tie-backs and tie-downs.

Why Would I Need Chemical Grout Injection?

There may be times that your Engineer wants to follow the pressure grouting process or underpinning process with a chemical grout injection process.  The purpose of the chemical grout is to consolidate and stabilize the upper soils around the perimeter or beneath the foundation of your home. 

There are 2 types of urethane resins that are commonly used for this application. The first is a two-part resin that expands to compact the soil & provide uplifting support beneath the structure. The second is a single component resin that permeates the soil, using a catalyst to solidify and strengthen the soils.

The injection pipes used in this process are 5/8" diameter and are generally inserted 5' to 10' below grade.  This entire process generally takes 1 or 2 days to complete.

Secure Foundation Systems, Inc. performs Chemical Grout Injection with both proficiency and time consciousness using custom machinery fabricated specifically for this procedure.

"The crew, from salesman to workers, were the most courtesy people I have ever met. They went out of their way to ensure the least amount of inconvenience to my family as possible, and always with a smile. It was hot; however, they would not even accept a drink of water or use of the bathroom." James & Marguerite S. Click here to read more testimonials and customer letters.
