EnviroSlope Stacked Geoweb


Enviro Slope Stacked Geoweb Slope at Kressview Ontario.

The EnviroSlopeTM System with stacked (tiered) Geoweb® sections is an economical solution to create attractive vegetated reinforced soil slopes and is recommended for slopes up to 70 degrees. The facing material for this option is the Geoweb cellular confinement material typically 150 mm high at each level, and three cells wide deep, and stacked and stepped back each layer to create the slope required by the client. The front cells are filled with seeded topsoil during construction. Geogrid soil reinforcement is installed at appropriate design lengths and spacing to support the required steepened slope.

The Geoweb facing materials are delivered to site in a collapsed format. Once expanded the standard sections consist of three cells by eight cells with a face width of approximately 2.64 metres X 0.152 m high or 0.40 square metres front face area per section. The geogrid soil reinforcement is delivered to site in rolls and cut to length on site to suit the design length requirements.

Reinforced slope structures are usually constructed in areas to save space. Typically the structure delivers advantages in right of way and reduced space footprint that could not be achieved with the slope of an unreinforced embankment. Applications include highway embankment construction, landslide repair, space savings in commercial building sites, industrial applications, decreased bridge spans, vegetated low-to-intermittent flow channels, temporary road widening for detours, embankment construction with fine grained soils, permanent levees, reduced embankment footprint in sensitive areas (e.g. parks), arch culvert end treatments, and residential steepened slope structures.
