Dry Risers and Wet Risers

We have the design capability and experience to carry out the installation of bespoke dry riser systems for organisations of all kinds. PTSG’s site engineers fabricate systems on site and make sure installation follows design drawings. Any alterations are dealt with as soon as they arise.

By law, dry risers must have fire engine access within 18m of the dry riser inlet box and have to be housed in a fire-resistant shaft. In commercial properties, this is usually under the staircase of a fire exit.

After the installation is complete, the riser is hydraulically pressure-tested to the British Standard BS9990 2015. A test certificate is then issued.
