Presto GEOWEB Slope Protection System
Slope Protection and Erosion Control with GEOWEB
GEOWEB slope systems stabilize soil, prevent erosion, and manage runoff effectively.
Nexterra's Presto GEOWEB Slope Protection System transforms vulnerable slopes into durable, high-performing surfaces that resist erosion, control runoff, and preserve the natural character of the landscape. Its three-dimensional cellular confinement structure locks infill materials in place, creating a stable and resilient surface that performs under hydraulic and gravitational stress.
Engineered Strength and Design Versatility
GEOWEB slope systems combine flexibility, confinement, and permeability to deliver reliable performance in challenging environments. The system adapts to natural contours and variable soil conditions, turning unstable slopes into stable structures that sustain both beauty and function.
- Cellular confinement distributes stress evenly across the slope, preventing rills, gullies, and surface displacement under flowing water.
- Anchored stability holds soil, stone, or vegetation firmly in place, maintaining surface integrity on steep or saturated terrain.
- The open-cell structure promotes infiltration and reduces runoff velocity, supporting sustainable stormwater management.
- Modular adaptability allows for smooth integration with drainage, retaining wall, or channel protection systems.
- Efficient installation and reduced material demand translate directly into lower project costs and smaller environmental footprints.
GEOWEB technology merges strength with environmental intelligence, creating a system that supports structural performance while enhancing the surrounding ecosystem.
Proven Results Across Applications
Across North America, GEOWEB slope protection systems have set the standard for performance, versatility, and long-term resilience. They turn steep, erosion-prone surfaces into stable, enduring landscapes that manage water with precision and preserve natural aesthetics across every project environment.
- Highway embankments and transportation slopes maintain strength and alignment through heavy rainfall, runoff, and temperature shifts.
- Vegetated installations grow into the structure, binding soil while creating living, self-healing systems that strengthen over time.
- Riverbanks, shorelines, and drainage channels retain form during high-flow events, protecting waterways and preventing material loss.
- Industrial and commercial projects benefit from reduced maintenance, improved drainage, and decades of consistent structural performance.
Each installation demonstrates the same lasting result: stability, sustainability, and confidence built into every layer of GEOWEB protection.
Upstream and Downstream Flow Balance
GEOWEB slope systems function as an integrated surface that harmonizes soil, structure, and flow. Installation begins at the downstream toe where load and drainage converge, then advances upward as panels expand and align with natural grade. This sequence ensures structural continuity, proper water conveyance, and enduring stability from base to crest.
- Interconnected cells diffuse runoff energy evenly, protecting the surface against scour and maintaining slope geometry.
- Anchoring and infill placement establish solid contact with the subgrade, preserving alignment through settlement or load shifts.
- Vegetated or aggregate finishes provide both filtration and flow control, balancing strength with environmental benefit.
- Drainage pathways guide water efficiently toward designated collection zones, reducing pressure and preventing saturation.
GEOWEB brings soil, structure, and flow into equilibrium, ensuring every slope performs with lasting strength, functional balance, and natural beauty.
