Comparative Flammability Demonstration in Drainage Pipes

Posted by & filed under Case Studies, Health & Safety.

Have you ever wondered the comparative flammability of different drainage pipes?   Polypropylene pipe, reinforced concrete pipe and high density polyethylene pipe. We look which drainage pipe will be crowned champion with this unedited test conducted in October, 2015! Dry hay is ignited in three 18/18 in pipes and allowed to burn safely. What happens next? Which pipe… Read more »

The precast manhole revolution: safer, higher quality, faster, cheaper – are you missing out?

Posted by & filed under Pipes & Manholes.

Traditionally, manhole construction has required the base to be formed in-situ where building of the channel, connections and benching occurs in the trench, often in confined spaces that can present a safety hazard for operatives frequently encountering wet and unpleasant conditions. The process can take around 40 hours per manhole to complete and is not… Read more »

Overspecification of pipe bedding – the implications

Posted by & filed under Costs, Design.

Bedding is an essential component in every “open cut” pipeline installation. Its primary function is to transfer loads between the pipe and the surrounding soil.  However, the design of the bedding system can have a significant impact on the cost of an installation and also on the environmental impact of the project as a whole.   … Read more »

Hydraulic efficiency of different pipe materials

Posted by & filed under Design.


Reliable estimation of the hydraulic performance of pipeline systems is one of the most important aspects of drainage design. There are many determining factors and many debates arguing the case for different pipe materials and configurations. To achieve hydraulic analysis accuracy, it is imperative that the designer has the correct design information and makes appropriate… Read more »

Some pros and cons of the Government’s new SuDS legislation
