Learn how to build a reinforced Allan Block retaining wall. With uniaxial grid you must roll out the grid perpendicular to the wall, cut the grid to the designed length, and repeat as you move along the wall. With a biaxial grid, such as AB Grid, you can simply select a roll width that matches the design length and roll the geogrid along the retaining wall.
Geogrid is a polyester woven fabric used to reinforce the soil behind a retaining wall. This video shows how to build a reinforced Allan Block retaining wall. With uniaxial grid you must roll out the grid perpendicular to the wall, cut the grid to the designed length, and repeat as you move along the wall. With a biaxial grid, such as AB Grid, you can simply select a roll width that matches the design length and roll the geogrid along the retaining wall.
