Concrete strength shall range from 3,000-5,000 psi depending upon requirements set forth. All concrete shall be reinforced with wire mesh as required.

Concrete Pavers

Existing material is excavated 6”-8” in depth depending upon soil conditions. Install graded base aggregate to desired depth then compact. Compact aggregate with a vibratory plate compactor in lifts to achieve proper compaction rate. Install 1” of fine Long Island sand. Set new pavers in a pattern to be agreed upon prior to installation. Sweep in additional sand between all stones as needed. Compact in place using a vibratory plate compactor to set stone. Repeat until all joints are filled with sand.
