Chemical & Slurry Grouting
Everyone knows about tile grouting, but in the language of foundation repair and soil remediation, grouting is a process by which various chemical or cementitious mixtures are pumped into the ground.
Grouting may be used for filling voids, soil consolidation, water control, and soil compaction. Each type of grouting has a specific purpose, as well as various pros and cons.
Our engineers will help you decide upon the right chemical grouting approach for your application. We offer shallow chemical grouting, slurry grouting and compaction grouting.
Polyurethane chemical grouting is used to improve soil capacities and strengths. It can be completed using two different types of urethane resins:
Rain is a good thing. It washes away dust and pollen and nourishes all growing things. But rain can cause foundation problems.
As water washes through joints and cracks in sidewalks, patios, pool decks, and driveways, it may carry fine soil particles away with it. Leaks or breaks in underground drain pipes may do the same thing.
Erosion from excess water may go unseen for years, but once it's severe enough, structures that initially had solid support, like foundations, begin to sink, crack, and sometimes fall!
Chemical grouting can turn loose, weak soil into a solid, sandstone-like mass.
There are several benefits of chemical grouting:
Chemical grouting stops further water flow through the soil.
Chemical grouting is lightweight and it doesn't add to the soil's load-bearing burden.
Chemical grouting can be injected into the soil from the surface with small 1/4-in. to 5/8-in. diameter pipes.
Chemical grouting may also be used to solidify loose fill and soils that were inadequately compacted prior to construction. In addition, it may be used to solidify soils prior to boring or excavation.
In many cases, chemical grouting is used to re-level concrete flatwork that has settled unevenly.
Slurry grouting is done using a cementitious grout.
This grouting technique is often used to fill voids discovered below a slab or foundation. It may also be used to fill voids created when a slab has been releveled using steel piers.
The grout, a loose cement mix, may be supplied by ready-mix trucks or mixed on site.
Small perimeter holes are bored into the affected concrete slab and the grout is pumped below the slab to fill the voids.
Once the grout has set up, the holes are filled and troweled smooth with patching cement.
Slurry grouting may also be used to inject a highly-liquid grout into shallow, loose soils under various types of structures. The liquid mix actually permeates the soil and causes its particles to bind together, making the soil more stable.
To inject the slurry, steel injection pipes, called rods, are driven to depths of 10 to 15 ft. at prescribed intervals around the building perimeter. Then grout is pumped into the soil under low pressure, while the building is monitored for movement.
Slurry grouting is used to fill voids below a slab or foundation. When a void or gap below a floor slab or foundation is present, there can be stress to these areas that can cause damage and/or displacement.
