Gravel-Lok Permeable Binder
Gravel-Lok is a high quality made in the USA pervious aggregate bonding system. Available in Clear which is UV stabilized for white or any color stone or Amber which is amber in color and will discolor light or white stones. As a single element moisture curing liquid there are no activators to mix prior to installation. By mixing and placing the aggregate or utilizing the pour over method, Gravel-Lok can be installed as you wish. Gravel-Lok makes an excellent binder or bonding agent suitable for Pathways, Patios, Driveways, Walkways, Parking Lots, Garden Paths, French Drains, Stone Scaping, and Tree Surrounds in residential, municipal, and commercial projects.
The Clear Formula:
The Clear Gravel-Lok is a UV treated binder and is clear in color making it ideal for white and gray and other stone colors that could be negatively affected by the yellowing affects of UV degradation.
The Amber Formula:
The Amber Gravel-Lok is a NON UV treated binder and is amber in color and will allow a slight yellowing of the aggregate due to UV rays. From an application standpoint the clear and amber binders are very similar but you should be careful about trying to pinch pennies with the amber binder if the color of your aggregate is important.
Both the Clear and Amber versions of Gravel-Lok are available in 1 Gallon, 5 Gallon, and 55 Gallon containers. Due to the awkwardness of installation with the 55 gallon drums most customers opt for the 5 gallon containers, even on very large projects.
