Anchor Colorado Stone
The beautiful rough hewn texture of the Anchor Colorado Stone™ delivers a natural, rock-like appearance. It is a popular product used in residential and commercial landscape designs. COMPOSITION AND MANUFACTURE Anchor Colorado Stone™ is made from a “no slump“ concrete mix. Made under extreme pressure and high frequency vibrations.
Depending on site conditions and or local building codes, engineering may be required. Step 1 - Site Preparation: Stake out project. Place a string line level on each string line and adjust to where all lines are level. Measure down in wall increments using the height of the wall unit to determine placement of the top of the wall courses. For small landscape walls (3 courses or less) it is required that the first course to be at least partially buried. For tall walls (4 to 8 courses) the first course should be fully buried at a minimum.

Step 2 - Excavation: All walls require excavation for a prepared base material that extends a minimum of six (6) inches in front and back of the wall. For small walls, dig this trench a minimum half the height of the wall unit deep. For tall walls, dig your trench to a minimum depth of a full wall unit height. Compact floor of this trench with a compactor or hand tamper. Step 3 - Base Preparation: For small wall base preparation, an option would be to place a mixture of dry sand and Portland cement (one shovel of Portland to four shovels of sand). Place the sand-cement mixture a minimum of four (4) inches at the bottom of the trench. For tall walls, you’ll need a more substantial base. Granular road base is preferable at a minimum four (4) inch placement. Compact the material with a compactor or hand tamper.

Step 4 - Leveling: For both small and tall walls a maximum of one-half inch of coarse sand is allowable to level the top profile of the base material. When placing wall units, level the surface of all wall units in both directions with a carpenter’s level. Replace the string-line where the top of your wall course will be and check for horizontal level prior to each course installation. Step 5 - Laying Stones: Always begin at the lowest point of the wall. Level each unit in both directions with a minimum two (2) foot carpenter’s level. Once the base course is complete, continue assembling additional courses by positioning the units in a running bond pattern relative to the course beneath, taking care not to align joints vertically. Securely engage the unit to the lower units. Backfill and compact material behind the wall in a four (4) inch to a maximum six (6) inch layer. Install a granular no fines material as a drainage zone a minimum of four (4) to six (6) inches thickness directly behind the wall. Compact materials with a compactor or hand tamper. A four (4) inch perforated plastic pipe may be required behind wall.

Step 6 - Cutting Stones: When building your wall, you may need partial stones to finish coursing. Place the to-be-cut unit at its finished position in the wall. Mark the cut line. To split a stone, use safety glasses, a hammer and a chisel. Place the unit on a hard surface. Position the chisel at the cut mark and proceed to hammer the chisel scoring the cut line. Score the unit on all sides. Once the perimeter score is complete, strike the chisel on the score line until it breaks.
