GRP Trenches



Our GRP Trench system is an adjustable width trench box (patent application no 1401475.7) which comes in three parts; base plate and two side panels. This allows for the 350mm deep trench unit to be assembled as the desired width, up to a maximum of 1200mm, drastically reducing the space required for both transport and site storage.


Installation can be expected to be in the region of one fifth of the time needed for pre-cast concrete installations. The units can be easily cut on site and adapted in-situ to suit any specific site conditions or changes.


Our GRP Trench system is one of the strongest composite protection systems in the marketplace. Coupled with our range of open mesh and covered trench covers, FibreGrid can offer the complete package for your needs.
