PermaStruct® Trench & Lid Systems are a unique alternative to pre-cast concrete trenches and have many advantages over conventional trenching systems.
PermaStruct® FRP Trenches, also known as a FRP Duct/FRP Culvert, are designed to protect cables and pipes that are laid under the ground. Services such as gas, water, electricity, communication and signals would not be possible without a trench to protect them from damage.
Trenches are joined by means of a simple universal fibreglass flange and can be easily drilled, bonded, and/or mechanically fixed if required.
