Testing & Proof of Concept

At Durable, we take pride in the fact that our work has been stress tested at the USDA Forest Service to validate Durable’s approach and ensure long-lasting, reliable results.

Testing produced the following:

  • Testing scenarios: Testing evaluated several different repair types compared to a virgin pile focusing on the lateral deflection limits of the pile.

  • Key finding: The point of the testing program was to determine the adequacy of the pile wrapping techniques as well as determining optimal wraps/dowel configurations. All pile wrap test specimens tested exceed capacities of the USDA splice method as well as LA DOTD allowable load values. It was also observed that the bond between the wrap materials and the timber did not fail as failure occurred between internal wood fibers.

Piling Protection

We also provide techniques to protect pilings from the elements.

Piles need to be protected from water exposure, UV rays, and potential channeling. There are various strategies that Durable implements to ensure long-term ultraviolet protection and minimal water degradation.
