Step 1. Install and compact the base rock

Moisten and compact base rock on entire installation area to an even depth of 4-inch or 6-inch, depending on residential or commercial application.

A vibratory plate can be used to compact the base rock; it should not be used to compact the GraniteCrete.

Step 2. Place dry mixture at the installation site

Step 3. Moisten and mix simultaneously

Lightly moisten the material with a hose end trigger sprayer attachment; avoiding puddling.  Rake area lightly to evenly distribute water throughout the mix.

Install second layer as above and screed at one inch above finish grade; when doing this, make sure to pay particular attention to the edges to ensure even material height, and lightly mist to dampen mixture.

Mist until both layers are damp.  Proper moisture is achieved when clenching your fist with the mixture it stays compacted and the color can be seen on your hands.

Step 4. Initial compaction, with close attention paid to edges and corners

After optimum moisture content is achieved for compaction, initial compaction can be performed by walking on the edges and corners, and through use of a 6” wooden masonry float, a 10” hand tamp, or a 36” water-filled lawn roller.

Pay particular attention to corners and edges to ensure tight compaction.  

Make sure to keep all tools clean at all times.  

Step 5. Finish 

Remove final imperfections and/or add texture with a medium-bristled broom before final compaction with a lawn roller. If desired, lightly pass a medium-bristled broom over the  surface to remove any slight imperfections, and then roll several times with a water-filled 36” lawn roller.

With larger installations, a  36″ lawn roller less than one ton in static position can be used.

Make sure with both applications, the drums are kept clean at all times.  Be sure to remove the spoils off the finished surface.

Step 6. Mist and Cure

Using a hose end trigger sprayer attachment, moisten the entire newly-installed GraniteCrete area – avoid puddling.

To discourage cracking, moisten newly-installed GraniteCrete on a daily basis, as practical.

Slow curing of GraniteCrete is important to avoid cracking.

Make sure there is no direct application of uncontrolled water (e.g. irrigation or sprinkler water) prior to final curing.

Creating and Using Cold Joints

If the installation will take longer than one day, cold joints can be used at the end of the work day.  Examples of cold joints are shown here and here.

Cold Joint Methods

Method One:

1. “Between pours,” stop at an area that makes the joint location look intentional. Take a chalk snap line just back from loose GraniteCrete into the compacted area and create a chalk line. Use either a masonry blade – or a square-nose shovel – and cut a straight line across the installation.
2. Continue with installation: Dampen the prior installation area. Place newly mixed GraniteCrete into the area, being careful not to overlap existing compacted material. Place a three foot length of 2″x4″ carefully along the edge of the new pour and compact by hitting/tapping the board with a single jack. Then, take a medium-bristled push broom and very lightly “feather” the two pours together.

Method Two:

1. Place a 2”X4” or 2”X6” piece of wood across the installation, loosely stake it, and finish compacting the material. Leave the board in place overnight.
2. The next day, carefully lift the wood up and away from the installed GraniteCrete. Continue the installation process as per step 2 under Method One, making sure to dampen the prior installation area.

Method Three: (Suggested for large open edges at the end of the work day)

1. Install steel edging at a location that looks “intentional” and aesthetically “makes sense.” Permanently install using the stakes provided. Completely finish the first day’s work.
2. The next day, simply continue with the installation. Make sure to dampen the prior installation area first. Leave the edging in place. Again, being careful not to leave any new material on the previously installed GraniteCrete.
