Installation Instructions
When GraniteCrete is installed correctly, there is no better surfacing solution for your landscaping project. GraniteCrete excels in appearance, durability and permeability – it performs like no other paving solution! To get the best out of GraniteCrete, it is important to follow the installation instructions on this page carefully from the start – putting in the base rock – to the finish – curing GraniteCrete.
The installation of GraniteCrete is a unique process. While not difficult, it is different from installing either loose decomposed granite or concrete. This page explains the process for installing GraniteCrete. To the right is a video that will show you the steps for installing GraniteCrete, and below is a detailed set of written instructions. You can also download the instructions to print them out.
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
GraniteCrete can be ordered pre-mixed with decomposed granite (DG) or it can be mixed onsite.
Onsite mixing:
Combine the decomposed granite and GraniteCrete admixture thoroughly. Again, be sure to only mix the amount that you can use in a single day. Our website features a Job Calculator that will help you determine the amount of material required for both residential and commercial applications. www.GraniteCrete.com/calculator.
Pre-mixed GraniteCrete:
GraniteCrete can be ordered pre-mixed with decomposed granite from many of our retailers. Please refer to our website for a list of retailers who offer pre-mixing. www.GraniteCrete.com/retailers.
We strongly recommend that you only order the amount of Pre-Mix you’ll be able to finish in one day. Decomposed granite is a bulk material that contains moisture. If left unused longer than one day, the mixture will begin to harden. If for any reason the material is not used, it must be tarped, and absolutely used the beginning of the next day.
The dry GraniteCrete-DG mixture will be laid down on your path in two layers, with each layer moistened and compacted individually. It is not required to cure the initial layer before installing the second layer.
Initial Layer:
Transport the GraniteCrete-DG mixture to the installation site by wheelbarrow for the first of the two layers. Spread the mixture evenly over the area to be installed.
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 lift 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 lifts 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 roller 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.
