INSTALLATION

Determine correct GeoEdge size required.
GeoEdge size is determined by adding the depth of the bedding layer and the paver thickness, subtracting 3/4” (19mm) from the total, and then rounding to the nearest vertical wall size.

Example: 3-1/8” (79.5mm) pavers on a 3” (76.2mm) layer of bedding stone.
Bedding layer = 3” (76.2mm)
Paver height = 3-1/8” (79.5mm)
Paver height plus bedding layer = 6-1/8” minus 3/4” = 5-3/8”.
....................................................155.7mm minus 19mm = 136.7mm
Round to nearest GeoEdge vertical wall height = 5-1/2” (139.7mm)

1. Base Preparation
   Prepare sub-base and base course(s) to specification.
   
   
2. Biaxial GeoGrid - Tenax MS 220 B or Equal
   Vehicular Application: Cut to a 6 foot (1.83 meter) width. Place 6 foot width by desired length over base course along perimeter. A minimum of 5 feet (1.53 meters) under the pavers and 6”-12” (152-304mm) extending to the outside of the paver installation. (Diagram A)
   
   Pedestrian Application: Cut to a 4 foot (1.22 meter) width. Place 4 foot width by desired length over base course along perimeter. A minimum of 3 feet (0.91 meters) under the pavers and 6”-12” (152-304mm) extending to the outside of the paver installation. (Diagram A)
   
   Geogrid Overlap. It is not necessary to overlap the geogrid. For corners, a butt and pass method can be utilized attaching the geogrid to the edge restraint along both edges. For angles, cut the geogrid apron to fit within the area and attach to the GeoEdge along the edges.
   
   
3. GeoEdge Installation
   Establish specified elevation and perimeter of surface. Set GeoEdge (base away from pavers) over geogrid at desired perimeter. Fill gaps under GeoEdge with base material to provide proper support. Connect sections on base and sidewall using 1”x 2-3/4” (25.4mm x 70mm) sliding connectors. (Crimping of sidewall connectors optional using Permaloc Crimp Tool).
   
   Capture Plates. Slide capture plates under the GeoEdge base and geogrid. Align the inside edge of the capture plate approximately in line with the vetical wall of GeoEdge (Diagram B). Capture plate must overlap the base of adjacent sections of GeoEdge.
   
   Fasten GeoEdge to the capture plate using the pre-punched holes in the edging. Fasten each plate with three 1/4” - 14 x 1-1/4” (6.35mm - 14 x 31.75mm) hex washer, self tapping galvanized screws. Tighten the screws to securely compress the geogrid between the edging and capture plates.
   
   Space capture plates equidistant along the edging section using 5 plates per eight foot section of edging.
   
   Curves / Angles. The TRUTRAC base allows curves and angles to be formed by removing the twist-and-snap tabs. To form a curve, remove the appropriate tabs and form the edging to the desired radius. Form curves before attaching geogrid and capture plates.
   
   
4. Setting Course and Permeable Paver Installation
   GeoEdge is designed to retain the full depth of the setting course. Install setting course and permeable pavers per specification.
   
   
5. Perimeter Backfill
   It is critical to backfill and compact the perimeter. Backfill adjacent material 1/2”– 3/4” (12.7mm–19mm) below paver surface or as specified. Backfill should extend beyond the edge restraint a minimum of 12” (304mm).

NOTE: When installing Aluminum edging in direct contact with ACQ treated lumber we recommend installing a barrier material such as Grace Vycor® Deck Protector™.
