Soil Stabilization

Soil stabilization is defined as a technique to improve the compressive strength of any substrate. We at Brosco use the most technologically advanced methods available to the industry. Soil stabilization has become one of the most useful solutions to treat soft and unstable soils. Due to the scarcity of construction land available in urban areas, soil stabilization has come a long way to becoming one of the most common and useful solutions to treat unstable soils so that structures can be placed safely without the risk of large settlements. Brosco’s unique techniques for stabilizing soils is a proven, non-destructive, extremely effective solution to increase soil load bearing capacity and compact weak soil substrate without a major need for heavy equipment and a lengthy, messy work site. Our process can be applied to a number of different projects and applications. For all your soil stabilization needs, call BROSCO!

 

Definition - Chemical Grouting/ Soil Stabilization

 

·      A form of permeation grouting

 

·       Increasing in popularity as an efficient and economical grouting technique which uses chemical grout of different characteristics depending on application to fill small or large voids in the soil

 

·       Materials commonly used consist of polyurethanes, epoxies and specially formulated environmentally friendly chemical grout resins

 

 

Types of techniques – How its done

 

Soil stabilization stops leaksMost Common- Pipe Injection

 

Once loose unstable soil areas have been identified, we at Brosco employ a system where we pound threaded pipe (sizes dependent on the job application, ½- ¾ is most common) into the suspected void areas. Once pipes have been pounded to our unstable ground at designated depths (sometimes depths as deep as 25-30 feet) we then hook high pressure/ high volume resin pump lines to ends of pipe using our quick couple system and begin to inject our resin at high pressure. Once the resin begins its reaction it binds all the loose substrate in its path into an impermeable mass substance and increasing its compressive strength. As we continue our injection we use hydraulic jacking systems to pull our pipe back out while still injecting, building up the strength of all soil in the path of the pipe. For most of our applications, uses of multiple injection points are necessary to stabilize area identified.

 

There are many techniques available to enhancing the strengths and properties of the unstable soils. Please call for more details about your project.

 

 

 

 

 

Uses of Soil Stabilization

 

The soils best suited for soil stabilization are fine granular soils, with fine sand pigment. It is used to strengthen the substrate and prevent excessive movement.

 

- Improving the strength and weight bearing capacity of the ground.

- Reducing the potential for settlement

- Reducing the time during which the settlement takes place

- Removing or excluding water from the ground

- Treat weak soils to achieve required engineered characteristics

- Prevent large settlements of structure due to weak soils

 

 Chemical Characteristics

 

Polyurethane chemical grout is composed of two formulations of water-activated materials called hydrophobic and hydrophilic resins

 

Hydrophobic Resins

 

The word hydrophobic literally means "water-fearing," and it describes the segregation and apparent repulsion between water and nonpolar substances.

 

Hydrophilic Resins

 

Hydrophilic polyurethanes should always be used to stop water leaks in cracks! Hydrophilic resins seek out water in a crack. They chase the water and absorb into the tight micro-cracks and pores of the concrete. This gives hydrophilic resins a tenacious bond to the wet concrete. Hydrophobic resins repel water in a crack. They resist movement towards wet areas and will not absorb into tight micro cracks and pores in the concrete. They may be forced in under pressure, but the water will act as a bond breaker between the polyurethane foam and the concrete resulting in extremely low bond strengths.

 

 

Water Control

 

When injected into cracks, the resin grout forms a waterproof bond while expanding to fill any fractures. This procedure offers a less expensive method to seal joints and fracture. Brosco’s unique technique can be accomplished from the interior of a structure or exterior depending on accessibility constraints. In most cases the chemical resin is injected along the negative flow path, sealing and preventing flow through the crack.
