First install of new tieback system goes swimmingly

June 1, 2011

Forestry projects are challenging. Their rugged, undeveloped terrain makes for difficult working conditions and the forest’s many inhabitants – whether furry, feathered or scaled – require special consideration.

Big R’s new US Patented Wire Mesh Tieback System was designed to speed the installation and reduce the cost of structural plate stream crossings by eliminating the need for concrete collars on their cut plate end sections.

The forest is no place for concrete

Many forestry site developers use buried metal structures to construct stream crossings. Their cut plate sections are modified to meet site conditions and often require additional reinforcement. Concrete collars and longitudinal reinforcement are traditionally used, but both methods are tedious and costly. So Big R's engineer team worked to develop an innovative alternative: a Wire Mesh Tieback System.

The Solution: Our patented Wire Mesh Tieback System

Wire mesh reinforcement provides an economical, easy-to-construct alternative to concrete collars. Our new system secures heavy-duty wire soil reinforcement mats to the structure, allowing for larger cut ring sections with better deflection control.

A Super•Cor Box Culvert fish passage replacement in Oregon’s Malheur National Forest was one of the first installations for this new system, and it went very well. No concrete was needed. The client saved time and money. And, with minimal site impact, the fish were swimming freely again in no time.
