Fort Mott State Park | Historic Rehabilitation

Pennsville, New Jersey

2012 Honorable Mention | Rehabilitation and Restoration

Given the Honorable Mention in 2012, Fort Mott, once a post-Civil War outpost, now a New Jersey State Park. The Fort was constructed in 1872, and became a State Park in 1947. Situated on the Delaware River, the original walls of the fort were constructed of solid, 20-foot thick concrete walls faced with large earthen berm on the side of the River, otherwise known as a dyke.

A challenge for Cruz Concrete is always welcomed, it allows us to be innovative and to grow. This project provided a few of those.

  • As a historic landmark, Cruz had utilized a concrete mix of 3,000 psi, to match the existing concrete type and texture. A series of mock-ups were produced to reach the match.

  • Specifications called for natural cement, as was used in the 1870’s. This is no longer found in the region, it is only naturally occurring now in England. Cruz proposed a portland cement 4:1 grout mixture as an alternate to meet the LEED requirements.

  • Interior walls of the fort were severely spalled with deteriorated concrete ranging from 4 to 20-inches deep. The repair method originally called for was “form-and-pour”, Cruz proposed a dry-mix shotcrete approach which was accepted. 4 - 18-inches of shotcrete was placed over everything and restored back to the original lines.
