Dura-Mat is an effective product for erosion control in spillways and retention pond applications. These interlocking concrete units fasten together on all sides, forming a permanent, protective carpet with a solid-to-void ratio that allows for vegetation growth when desired.
DuraMat is designed as an interlocking puzzle-like unit which locks with each neighboring stone to form a strong cohesive mat for use in erosion control applications and retention pond floors.
RECOMMENDED BASE STABILIZATION – one layer of DriveGrid™ stabilization grid between subgrade and base material. Recommended depth 8” to 10” below pavers for maximum stability and performance. Use under Standard Base only.
STANDARD BASE – Min. 6” – 8” of ¾” Crusher Run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% Standard Proctor Density (SPD). When available, use architect’s or engineer’s specific site engineering for installation.
STANDARD BEDDING COURSE – no bedding required. Install directly on base material.
JOINTING MATERIAL AND JOINT STABILIZATION - Fill all holes with free-draining aggregate or as specified by engineer.
HANDLING – This product is heavy and a two-man clamp is recommended for placement.
EDGE RESTRAINT - A concrete curb or a “sub-surface concrete wedge” can also be installed to retain the edge.
PAVER COMPACTION - For the final compaction, a “rubber roller compactor” will give you the best results without breaking the units.
CLEANERS – Not applicable
SEALERS - Not applicable
