soil stabilization Applications

Problem: Poor load-bearing soils pose a significant problem for transportation and construction needs. Unpaved areas, such as access roads, paths, parking lots, driveways, etc can be highly vulnerable to near-surface shear failure and rutting, especially in moist conditions or areas with higher expected loads. Typically, engineers bridge over weak soils with rigid structures such as thick, reinforced concrete for roads and highways. However, such techniques are prohibitively expensive and inordinately difficult to install. The poorer the quality of the sub-base and the heavier the expected loads, the greater the amount and better the quality of support required.

In-situ geochemical fixation using a chemical reductant such as Remotox (calcium polysulfide) converts the soluble toxic metals into insoluble non-toxic compounds. Remotox has proven to be effective under a wide range of conditions. It is considered more stable and persistent than other reductants in subsurface environments, and is relatively safe to handle in the field and easy to apply.

Stream banks and shorelines can present far-reaching erosion and sediment control challenges. Variable flow conditions and shoreline shear stresses must be considered as well as the effects of flooding, runoff and topography. The need to protect water quality plus aquatic and wildlife habitats can be critical. No matter what erosion control problems and other issues are part of your project, you can be sure we have a solution that works. Whether your shoreline or stream bank project is simple or demanding, and whether it requires temporary and/or permanent erosion control solutions, you can rely on North American Green`s RollMax Rolled Erosion Control Systems and RevetMax Flexible Revetment Systems for durable protection, stabilization and reinforcement.

Pore pressure variability and control is one of the most significant aspects of Geotechnical Engineering practice related to slope stability, underground openings, foundation of heavy structures, and water retention facilities. Pore pressure effects are most often controlled by natural small-scale hydrogeologic details. Characterization and management of pore pressures requires closely-arrayed repeated measurements to determine the effects of these details for design of appropriate mitigation measures, for performance monitoring and control of the selected mitigation measure. Since the late 1970’s the Westbay System has been used on some of the largest landslide studies in the world.

GEOWEB geocells offer a better “solution set” to soil stability challenges for accessing sites over soft ground, controlling and containing stormwater, protecting geomembranes for basins, tailings, and heap leach pads, and reclaiming slopes at the time of closure. Through 3D confinement and strengthening of infill, less material—even on-site waste rock—may be used. GEOWEB solutions offer increased speed of operation, lower maintenance, safer installation, and a lower total cost of ownership.

Safe and Economical Solutions for Site Work. Presto Geosystems has a 35+ year proven track record in civil site construction and restoration solving soil stability and access challenges. Through infill confinement, Presto’s GEOWEB 3D geocells reduce cross-sectional requirements by 50% or more for tracking pads, construction staging areas, access roads and work platforms – and they perform well over soft ground. The safest and most economical portable mats, GEOTERRA, offer fast, temporary site access.

The GEOWEB system is the ‘go to’ solution for challenging soil stability problems for both new construction and repair work. The GEOWEB 3D system is a versatile solution for ballast reinforcement, yard stabilization and erosion protection of embankments and stormwater channels, offering a more economical solution than geogrids or other 2D solutions - especially in soft soil environments and in heavy, repeated loading areas.

Power companies face access challenges as they move heavy vehicles across wet, soft ground for maintenance of power lines and utilities. Access is often through environmentally-sensitive areas such as marshes and low-water crossings and undeveloped land with low soil strength. With the GEOWEB system, roads are built with 50% less cross section of aggregate, even allowing use of locally-available fill, to support heavy vehicles with minimal environmental impact. Whether for maintenance vehicle access at substations – or across land to service utility and power lines, the GEOWEB system is a surface stabilization system that is easy to deploy, easy to install, and requires virtually no maintenance.

Airport Runway, Taxiway and Shoulder Stabilization. Airport pavements designed to support heavy commercial aircraft and vehicle loads require a stable base to maintain pavement performance. This can be challenging, especially in areas with soft soils and poor soils prone to settlement. The GEOWEB system stabilizes the pavement base layer with 50% less fill, and offers a more stable base that results in longer pavement life. The GEOWEB system is an effective base stabilization system as well as surface protection for unpaved, permeable shoulders and access way.

Polymeric liners are prone to puncture by inclusions within the underlying soil. Thick, non-woven geotextile can be used to give protection to liners during installation. Often the upper slopes are exposed to damage and it is a good practice to cover these areas with a depth of soil which will sustain vegetation. Alternatively, a stone or concrete substance can be used to achieve a hard landscaped appearance. Our product will protect the liner from puncture whilst also providing a degree of slope stability.

Posi-Shell erosion control coatings are the perfect low-cost solution to protect and stabilize slopes. Our long-term coatings are spray-applied and allow engineers or operators to protect acres (hectares) of slope in a single day. The finished coating is durable and textured, reducing water energy across large areas. The final product eliminates erosion, siltation, and (as a result) expensive rework. The product can be designed to last for years and is easily tracked into slopes when intermediate protection is no longer necessary. Indeed, when integrated, Posi-Shell actually improves soil quality by conditioning it for future seeding. Posi-Shell’s simplicity and durability make it tremendously effective at controlling windblown dust, infiltration, or runoff associated with clean or contaminated stockpiles. Unlike cumbersome tarps or geo-membranes, Posi-Shell erosion control coatings are spray applied and do not require any ballast. Posi-Shell conforms and adheres to any topography and delivers 100% clean runoff. Stockpile loading or removal is accomplished by breaking into the coating where desired. Active areas may be left open or quickly resealed if required. Posi-Shell erosion control coatings are ideal for protecting expensive piles of salt, coal, or cement clinker; and are used extensively for containing hazardous or radioactive soils.
