Installation Recommendations

· 30" maximum wall height with 3" below grade for retained situations or consult a licensed professional engineer for your particular application.

· Base should be 14"-16" wide by 6" deep and well compacted.

· For base and backfill, use multiple sized crushed stone ranging from 1/4" - 1 1/2" in size with less than 10% fines.

· Lay a flexible drain pipe the length of the wall to relive hydrostatic water pressure from building up behind a retaining wall. (see illustration above).

·  Offset vertical joints of units to maximize wall strength. (see A below)

· When stones are stacked vertically on 4" side, another stone should be placed behind it to create an 8" wall thickness. (see B below)

· Vertical stones exposing the 4�h face should protrude the full 12�h toward the bank in retaining wall situations (see C below)

· Filter fabric can be used to separate clean gravel backfill from topsoil.

· Consider using integrated columns or pilasters for strength in free-standing  and retaining walls. (see picture in lower left below)

· Use  SRW masonry adhesive or equivalent to adhere at least the top two rows.
