Generally, most VERSA-LOK units need geogrid for walls taller than three to four feet. If there are steep slopes near the wall, loading above the wall, tiered walls or poor soils, then even shorter walls may need geogrid.
Do I need to anchor a retaining wall?
Retaining walls have to work a lot harder than freestanding walls. ... Tie-backs, also called dead-man anchors, should be installed to tie the wall into soil well behind the wall. Drains should be laid behind the foot of the wall to move water away, before pressure can build up and push against the wall.Dec 28, 2020

Why do you use geogrid?
Geogrid is a geosynthetic material used to reinforce soils and similar materials. Geogrids are commonly used to reinforce retaining walls, sub-bases or sub soils below roads or structures. Soils pull apart under tension. Compared to soil, geogrids are stronger in tension.Jan 15, 2014
How much geogrid do I need?
To determine the number of rolls needed, multiply the length of your wall (in feet) by the number of layers needed, and then divide by 50 (the length of a roll of AB Reinforcement Geogrid).
How far back should geogrid go?
For an SRW with geogrid, the rule is a minimum geogrid length of 60% wall height. So, for an 10' SRW with geogrid, you need the geogrid at least 6' back from the wall face.
Is geogrid necessary for retaining wall?
For most 6″ or 8″ wide split-face limestone retaining walls, geogrid will be something to consider when the exposed wall height exceeds 24″. ... Once the retaining wall is over 6′ in height, if it isn't being built from 24″+ wide limestone outcroppings or similarly sized, dense material, geogrid is required.Mar 8, 2013
