Compaction: packing of the base and fill for retaining wall construction Setback: the distance a second row is set behind the first row Drainpipe: removes drainage water behind a wall Geogrid: mesh reinforcement extending rearward from the retaining wall into the fill Slope: the amount of fall or rise of the earth around the retaining wall Surcharge: any added pressure applied against a retaining wall Drainage Channel: a small channel located on the inside top of the retaining wall that allows surface water to drain away from the wall Convex Curve: a shape of curve that when looking at the face of the units, the curve's center is closer to you than the outer edges Concave Curve: a shape of curve that when looking at the face of the units, the curve's center is farther away from you than the outer edges Uniaxial Geogrid: geogrid that is reinforced in one direction Biaxial Geogrid: geogrid that is reinforced in two directions Geotextile (filter fabric)- fabric material which allows moisture to pass through but limits soil particles from passing through Construction Drawings: drawings which specify the requirements of the retaining wall installation. Construction Drawings: drawings which specify the requirements of the retaining wall installation. Specification Guidelines: standards specifying the requirements and installation of retaining walls and of installing geogrid within those walls. Geogrid Design Tables: tables which specify the geogrid requirements for Classic 6", Classic 8" and for ROCKWOOD Legend units when any of the ROCKWOOD units are used in a retaining wall where there is no surcharge load, where there is a surcharge load, and where the soil behind the wall is sloped. Special Installation Techniques: instructions for the installation of sharp corners, steps, inside corners and other retaining wall designs and applications. |
