Pathway Paving Stones Concrete Paving Systems Engineering Services Technical Bulletin Concrete pavers are strong, durable, easy to install, and provide a value added option on any project. Accessibility Concrete pavers comply with ADA requirements for slip resistance, surface level and vibration levels. Bond Patterns A wide variety of bond patterns is possible. This is just a small sample of possible bond patterns. (Note: All quantities based on a 10 x 10 sq. ft. area.) Tech_Bulletin_Concrete Paving Systems.doc 03/21/14
