Pre-formed PVC trench is available in 5 off-the-shelf standard sizes.  Internally, these are 100 x 100mm, 150 x 150mm, 200 x 200mm, 225 x 225mm and 300 x 225mm, as shown below:

All trench orders include end caps.  Please ensure to specify the length of each separate run when ordering to ensure the correct number of end caps are supplied.

Installation Guidelines

There are many ways to install R&S Grating pre-formed PVC trench system, and the best way is usually determined by the site conditions and the final intended application.

The most important part to ensure the correct operation of the trench system is that sufficient concrete is poured underneath the mild steel angle frame. The frame will transfer applied loads to the concrete, so it must be properly supported.

Below is a guide to rebate sizes and one possible installation method. As many methods of installation work for pre-formed PVC trench, if you’re unsure of the best method for your particular application, please give us a call to discuss your options.

 

Installation Guidelines

R&S Grating’s pre-formed PVC trench is an inbuilt formwork that eliminates the need for labour-intensive boxing on site. The pre-formed PVC trench is non-load bearing after installation, making it an economical alternative to traditional boxing that won’t affect the strength of the trench.

 

The typical application load path sees the grate carry the load to the mild steel frame along the edges, which in turn passes the load to the supporting concrete underneath. This is shown in the diagram below.
