How strong is Gravel-Lok?

Gravel-Lok is a system. The top layer of bonded aggregates has the structural integrity of asphalt. The key to any pavement surface is the foundation it is built on. Below the bonded aggregates is Cell Tek's Geocellular Confinement System which constrains open-graded aggregates. 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.
