Anchor™ Highland Stone® 3-inch / 6-inch Combination Multiheight Retaining Wall System BASIC INSTALLATION – SEE ANCHOR ™ SEQUENT ™ PATTERN ON BACK 1. Stake Out the Wall’s Placement: Excavate for the leveling pad to the lines and grades shown on the approved plans and excavate enough soil behind the wall for the reinforcement material. The trench for the leveling pad should be a minimum of 24 inches wide and 6 inches deep. 2. Leveling Pad: An aggregate leveling pad is made of a good compactible base material of 3/4 inch minus with fines. The pad must extend 6 inches in front and behind the first course of stone and be at least 6 inches deep. Compact the aggregate and make sure it is level. 3. Base Course: Run a string line along the back of the stone to align the wall units. Use 6 inch height only stones in the lowest course in the elevation of the wall. Remove the rear lip of the stone so that the stone will lie flat on the leveling pad. Place the stones side by side, flush against each other, and in full contact with the leveling pad. Level front to back and side to side. Check the stones for proper alignment. 4. Next Lift Construction: Clean any debris off the top of the stones. Place the second course of stones, on the base course while maintaining staggered bond, and push each stone as far as possible to ensure the correct setback. Backfill with 12 inches of drainage aggregate directly behind the stone and fill in soil behind the aggregate. Fill all voids behind and between concrete wall units with drainage aggregate. Compact the backfill before the next course is laid. Avoid driving heavy equipment near the wall. Hand-operated equipment should be used within 4 feet of the wall units, or half of the wall height.
5. Drainage Design: Place the drain tile as low as possible behind the wall so water drains down and away from the wall into a storm drain, or to an area lower than the wall. 6. Compaction: Shovel the in-fill soil behind the drainage aggregate and compact the in-fill with a compacting device. Make sure the aggregate is level with or slightly below the top of the laid course. 7. Reinforcement: Check your wall construction plan for which courses will need reinforcement grid. Measure and cut the reinforcement grid to the design length in the plans. The reinforcement grid has a design strength direction, which must be laid perpendicular to the wall. Place the front edge of the material on the course, as per wall plan, 2 inches from the face of the stone. Apply the next course of stones to secure it in place. Pull the reinforcement taut and pin the back edge in place with stakes. Add drainage aggregate behind the stones, then add the in-fill soil and compact it. Place the front edge of the reinforcement on top of the stone, making sure it is within 2 inches of the face of the stone. A minimum of 6 inches of backfill is required prior to operating vehicles on the reinforcement. 8. Finish Grade and Surface Drainage: Protect the wall with a finished grade at the top and bottom. To ensure proper water drainage away from the wall, grade crest of wall to accommodate positive drainage.

Anchor™ Highland Stone® 3-inch / 6-inch Combination Multiheight Retaining Wall System Sequent™ Installation Pattern Combine the Highland Stone® 3-inch and 6-inch wall systems to construct a multiple-height wall with the easy-to-use Sequent™ panel installation pattern. This panel approach breaks up the horizontal lines of a typical single-height product. The repeating Sequent™ installation pattern is easy for contractors to install on a large scale in order to create a random, textured look. Estimating Information 1) Determine the square footage of exposed wall. a) Each panel covers 2.25 sq. ft. Divide the square footage of exposed wall by 2.25 to determine the number of panels. b) Each pallet of Highland Stone® 6-inch Combo can complete 20 panels. Divide the number of panels by 20 (rounding up) to determine the number of Highland Stone® 6-inch Combo pallets required. c) Each pallet of Highland Stone® 3-inch Combo can complete 96 panels. Divide the number of panels by 96 (rounding up) to determine the number of Highland Stone® 3-inch Combo pallets required. 2) Determine the linear footage of base course, and divide by the appropriate factor below to calculate the amount of material required. a) Highland Stone® 6 inch Combo = 60 linear feet per pallet. b) 18-inch-only blocks: 1.5 linear feet per stone. 3) Add the exposed wall and base course requirements. Don’t forget the caps!
