Here are some things to consider when working with Gravel-Lok:

• Liquid should be stored prior to installation at 70 degrees and above.
• Gravel-Lok should be applied by pouring or mixing.  Call 888-851-0051 for proper guidance on installation for your application.
• No rain 24 hours before and after Installation.
• Stones should be clean and dry prior to installation.
• Gravel-Lok is available in both an amber and clear version. For the amber liquid, avoid whitish colored stones. 
( If you are using whitish colored stones we recommend using the Clear version.)
• Wear long sleeves, protective eye wear and appropriate respiratory protection when handling Gravel-Lok.
• Protect surrounding areas with plastic to avoid staining.
• Stones should be rolled and leveled before pouring on Gravel-Lok.
• Gravel-Lok can bond stones from 1/4" up to 3" in size.
• Smaller stones will require more liquid than larger stones.

AGGREGATE: A variety of materials may be used. The aggregates should be washed of dirt, fine particles, etc and needs to be dry before applying Gravel-Lok. The base coUrse should be 3/4” angular blue stone (also known as #57 stone) at a minimum of 2 ½” thick. The decorative layer stone should range in any size from 1/4” to 3” angular or round stones. Angular stones have more contact points than round stones. In using angular stone instead of round, you can achieve a stronger load capacity on driving surfaces. Round stones tend to be smoother on the feet, however both stones are adequate. Always test on an inconspicuous area or create a sample prior to installing. Gravel-Lok may have difficulty adhering to limestone based aggregates over the long term. Since original Gravel-Lok is an amber liquid, whitish colored stones are not recommended (use Gravel-Lok Clear instead).

STRENGTH: The key to any pavement surface is the foundation it is built on. Cell-Tek’s Geo-cellular confinement system constrains open graded aggregates which are used for porous pavement applications and increases load support. The passive resistance of the infilled cells prevents lateral movement and distributes the load over a wider area. The system also reduces the impact on the subgrade up to 28% while reducing the amount of base material required to support traditional pavements. Using LSG-3 with a 3” cell depth is the equivalent to having 12"-14” of unconfined base. EDGING (OPTIONAL): Edging material may be wood, masonry, metal or plastic. Excavated soil can also be used but care should be taken to obtain the full thickness and avoid the creation of feathered edges.
