Soil Stabilization Solutions
Plan ahead. Soil stabilization will reduce your costs both now and later.
A pavement section or building structure is only as good as the soil underneath it. Stabilize now and save.
High Structural Value, Low Cost Alternatives
Low R-values. High expansiveness. Moisture. Poor workability. Lack of compressive strength. When the soil you plan to build on is found to be unsuitable, the common recommendation is to excavate, remove and replace.
There’s a better alternative. Instead of incurring high costs and lengthy delays, call in Pavement Recycling Systems (PRS). We will re-engineer your existing soil to provide a structurally superior sub-base that has the properties you need.
Is your project on solid ground? Test before you invest.
The best time to bring in our soil engineers is early on in the design engineering phase of your project. We work with your engineers to perform a battery of tests both on-site and in the lab to evaluate soil properties and condition. A recommendation is developed for a stabilization solution that includes the application of additives to permanently upgrade the structural properties of the soil.
Optimize expansion index reduction.

Plan ahead. Proactive soil stabilization will reduce your costs both now and later.
Insure against the high costs of instability.
A structure is only as stable as the soil that supports it. For example, expansive soils generate about $2 to $6 billion per year in damage to overlying structures. But that’s long term. How about now? During construction, our contractor and agency clients have saved anywhere between 30% and 60% by cutting the expense of “remove and replace”, reducing grading costs, and time savings of between 50% and 100%, depending on conditions.
PRS: Advanced chemistry and engineering.
Our PRS team has built a track record based on expertise in the latest technology. We use chemical stabilizers such as lime and cement in the right combinations to upgrade structural value and workability. Ask us for the latest engineering data.
Green and government approved.
PRS soil stabilization techniques are environmentally sound because they rehabilitate and preserve in-place soils and cut down the inherent resource-waste and air pollution of import/export alternatives. The processes are approved and specified by the FAA, FHWA, ASTM, Caltrans, and Greenbook, along with many local agencies. We work both directly and through our contractor customers who are among the top companies in the West.
Parking areas, malls and developments.
When soils are expansive, weak or otherwise unsuitable, stabilize instead of importing and exporting.
Increase bearing capacity for foundation support by reducing soil expansion and plastic indices. Stabilized soils are easier to excavate. Photo: footing excavations in stabilized pad.
From lake liners to dam facings, we reduce permeability and increase compressive strength by mixing Portland cement with on-site soil and water (“Soil cement”).
High performance, lower cost, environmentally sound.
- Structural value: Reduced expansion, higher R-value and strength, improved workability and compaction, and lower permeability.
- Economics: minimizes import-export cost and reduces structural section. Pre-planning prevents costly surprises now and later.
- Environmental: Reclaims in-place soil, conserves resources. Fewer truckloads in and out (up to 40-to-1) means less pollution and less impact on residents and businesses.
Soil cement or Bentonite for water resources and landfills.
Water resources like lakes present special challenges, as do landfills.
We reduce permeability and increase compressive strength by mixing Portland cement with on-site soil and water (“Soil concrete”). Soil cement’s comparatively low cost, ease of construction, utilization of on-site soils make it economical as well as durable. Soil-cement has served as a low permeability lining materials in water resources for over 50 years. In addition to water storage reservoirs soil cement has been used for:
- Pond and lake liners
- Channel and slope protection
- Wastewater-treatment lagoons
- Sludge-drying beds
- Solid waste landfills
Another option is soil treatment with Bentonite, which allows for maximum creative expression in artificial lakes and ponds. It uses existing soil as part of the liner system, and is the ultimate protection against landfill leakage.
Spreading and mixing bentonite into existing soils provides lower permeability for the creation of artificial lakes and ponds. Bentonite treated material is also used as an effective way to contain leachates within landfill limits.
