What type of maintenance can I expect with the Gravel-Lok pavement?

Gravel-Lok is relatively maintenance-free and no annual treatment is necessary. If the system is being used for vehicular traffic some loose stones may occur depending on the type of stone used and degree of abuse. Typically, you can expect about 1% of stones to dislodge or become loose in about a 5 year period. If desired, a disturbed area can be treated with more Gravel-Lok.
