Installation – Mix Method
(with LSG Series® Load Support Grid)
Excavate the job site. Properly grade subgrade to allow water to flow away from any structures. Add drainage if necessary. Install moisture barrier if project meets a foundation with a basement.
Layout geotextile fabric. This creates a barrier to prevent sediments from migrating up into the system and causing future settlement. Geotextile fabric must separate aggregates from subgrade and soils on all sides of the project.
Note: We recommend DuPont geotextiles.
Install Cell-Tek LSG SERIES® Load Support Grid. This reinforces the base material to prevent lateral movement.
The cells should be infilled with a washed aggregate infill equivalent to a #57 (3/4”) stone to allow for maximum permeability. Overfill cells by 1″.
Install edging (plastic, aluminum, etc.). This creates a clean edge to define the shape of the surface’s final contours.
Wash decorative stones and allow to dry (or use triple-washed Gravel-Lok® Pebbles). Mix stones with Gravel-Lok® in a plastic bucket, cement mixer or wheelbarrow.
In most cases, mixing 20-24 oz. of liquid with a 5 gallon bucket of stones is ideal. Important: a plastic 5 gallon bucket is considered ‘full’ when the contents are filled a few inches below the top of the bucket. Do not completely fill the bucket to the top with stones.
Using a ratio of 20 oz. of liquid to a five gallon bucket of stone, the coverage rate is approx. 93 sf per five gallon container of Gravel-Lok® based on mixing with stone and troweling out at 2″ deep. (approx. 18.6 sf per gallon)

Allow 24 hours to cure. Rope off treated area to protect it from people and animals. Do not walk on the surface before it has cured. Do not cover with plastic. This will trap in moisture and cause premature curing.
