Slope Stabilization Grid - 4" - SlopeGrid
FREE SHIPPING
SlopeGrid 4" is a 3D geocell that locks soil and aggregate in place to stop erosion on slopes.
A blanket of connected 4" cells confines its fill and anchors to the hillside, holding ground together where wind, rain, and runoff would otherwise wash it away. Fill it with topsoil and seed for a vegetated finish, or with stone for hard-armor channel and shoreline protection.
The 4" depth is the everyday profile for residential and light commercial slopes — a permanent, low-maintenance alternative to erosion blankets and retaining walls, built from virgin HDPE for decades of service.
Cell Depth: 4"
Unit Dimensions: 8' x 29' (expanded)
Square Feet Per Grid: 232
***For slopes over 45 degrees, please call for a custom quote.***
Why Choose SlopeGrid?
5 reasons SlopeGrid outperforms other erosion control methods on steep slopes
Permanent Protection — Not Temporary
Made from virgin HDPE with a decades-long service life. Unlike biodegradable blankets that fail within months, SlopeGrid keeps working long after vegetation is established.
Works on Slopes Too Steep for Blankets
Effective on grades steeper than 1:2 where erosion control blankets simply wash away. The 3D cell structure physically locks soil and aggregate against hydraulic forces.
Earth-Anchoring System Prevents Downslope Sliding
SlopeGrid's anchoring system mechanically attaches to the hillside — preventing the entire mat from sliding downhill. Flat 2D blankets have no equivalent protection.
Flexible Fill — Vegetated or Hard Armor
Fill with topsoil and seed for a natural vegetated slope, or gravel for hard-armor channel protection. One product handles applications that would otherwise need separate solutions.
Far Cheaper Than a Retaining Wall
For slopes too steep for blankets but not needing full concrete retention, SlopeGrid is a fraction of the cost of masonry or concrete walls — with free shipping and simple installation.
