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.
