Gravel-Lok LSG Series Loud Support Grid
Read Safety Data Sheet located on our website before installing Gravel-Lok®.
It is highly recommended you make test samples before starting any job to see
the effect of the liquid on the stones. Properly grade subgrade to allow water
to flow away from any structures. Add drainage if necessary. Install a
moisture barrier if the project meets a foundation with a basement. Geotextile
fabric must separate aggregates from subgrade and soils on all sides of the
project.
- All aggregates must be very clean and free from any fine particles or dirt. The cleaner the stone, the stronger the bond.
- Store Gravel-Lok® at 68 degrees or above until ready to use.
- Do not install if rain is expected within 12 hours.
- Do not cover with plastic. This will trap in moisture and cause premature curing.
- Install when the outdoor temperature is 50 degrees or above and will not drop below 50 for at least 12 hours. Allow 24 hours to cure.
- Rope off treated area to protect it from people and animals.

STEP 1:
Excavate the job site. Properly grade subgrade to allow water to flow away from any structures. Add drainage if necessary. Install a moisture barrier if the project meets a foundation with a basement. -
STEP 2:
Layout non-woven 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.

STEP 3:
Expand and install Cell-Tek LSG SERIES® Load Support Grid. This reinforces the base material to prevent lateral movement.
LSG-3: Pedestrian Traffic, 8,000 lb load bearing capacity LSG-4: Cars & Pick- Up Trucks, H10 Loading 40,000 lb LSG-6: Fire Access & Heavy Trucks, H20 Loading 80,000 lb. We do not recommend using Gravel-Lok with this heavy load.
More details on LSG Installation can be found here.
The goal is to create a continuous matrix of cells so each grid must be connected to the other. If the project is only a couple grids, drill holes and use zip ties. Larger projects can use our hand-held stapler or pneumatic stapler.
The cells should be infilled with a washed aggregate infill equivalent to a57 (3/4”) stone to allow for maximum 
-
STEP 4:
Spread, level and compact. -
STEP 5:
Install edging (plastic, aluminum, etc.). This creates a clean edge to define the shape of the surface’s final contours.
-
STEP 6:
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.
MIXING RATIO:
In most cases, mixing 20-24 oz. of liquid with a 5-gallon bucket of stones is ideal. Important: a plastic 5-gallon
the 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.
COVERAGE RATE:
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)
NOTE: For driving surfaces please contact Cell-Tek Geosynthetics at 888-851-0051. -
STEP 7:
Pour out in one small area.
Level and trowel to finish. -
STEP 8:
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. -
STEP 9:
Apply at least one roll coat using a medium nap foam paint roller. Allow each roll coat to cure for 24 hours before applying the next.
COVERAGE RATE PER ROLL COAT:
400-500 square feet per 5 gallon container. (90 – 100 sf per gallon)
