Presto Geosystems - Mining Soil Stability Systems

Presto Geosystems supports mine consultants and their owners to solve challenging soil stabilization problems with the genuine Geoweb® cellular confinement system. The Geoweb geocell system is a trusted, quality solution for mining soil stability needs including load support, slope stabilization, channel stabilization and vegetated retaining walls.

Mine haul roads

The Geoweb soil stabilization system strengthens and stabilizes on-site infill. It is an economical solution for mine haul and access roads, base improvement, and tailings containment. Geoweb sections are easily transported, even to remote locations, and can be quickly installed with ATRA® keys.

The system:

• Creates a stable driving surface, even over soft ground.
• Greatly reduces rolling resistance; improves cycles times and fuel savings, reduces mechanical wear and tire damage to haul trucks
• Reduces road maintenance costs
• Reduces overall cross section of stone (average 50% to 85%) and may allow use of on-site fill
• Transports easily and deploys quickly with on-site crews

Slope remediation

The Geoweb 3-D structure stabilizes the upper soil layer on embankments and solves challenging erosion control and slope-surface stability problems. Its main features include:

• Confined embankment infill supports sustainable vegetation or permeable infill
• Allows slopes to be designed steeper than when infill is unconfined
• Stable embankments create safer work areas in open pit mines, potentially increasing mineable area
• Provides protection to geomembranes (armored or vegetated)

Slope stabilization systems - Geoweb slope mining applications

The Geoweb slope stabilization system stabilizes the upper soil layer and solves challenging erosion control and slope-surface stability problems. Confining embankment infill in the 3D structure supports sustainable vegetation and allows slopes to be designed steeper than when infill is unconfined. It provides:

• Slope remediation / reclamation
• Geomembrane protection
• Wastewater and stormwater lagoons
• Slope weatherproofing

Channel armoring - open-channels and hydraulic structures

Create single or multi-layered Geoweb systems for open channels and stormwater control with variable infill options, including low-cost on-site aggregate. Our systems:

• Eliminate costly rip rap in drainage ditches and stormwater swales by using a low-maintenance, vegetated Geoweb/TRM system to resist higher velocities
• Confinement allows use of smaller aggregates, even on-site waste material
• Concrete infill may be used to achieve greater stability and resistance to flows

Geoweb channel mining applications

• Surface-water diversion channels
• Surface process-water channels
• Channel remediation
• Movement of tailings materials

Retaining walls for mine slopes

Geoweb retaining walls for mine slopes offer structural stability with the distinct advantage of a sustainable, completely vegetated facia. The earth-retention system can withstand reasonable differential settlement without loss of structural integrity, can be constructed in remote areas without specialized equipment, and may allow the use of economical on-site materials.

Our retaining walls for mine slopes provide:

• Steepened embankment stabilization in areas with limited site access
• Road cut and fill through mountainous areas
• Berm protection and stabilization of tailings/waste containment lagoons
