Concrete Pipes

Maintenance, Integrity and Durability

Integrity, durability and resistance to damage are main requirements for any pipeline system. Concrete pipes and manholes offer the most inherently strong option. Unlike vulnerable flexible pipe alternatives where the structure of the system will need to be built around the pipeline, the robustness of a precast pipe makes it less susceptible to the effects of poor bedding and installation. This is one of the main reasons why a concrete pipe and manhole can serve for well over 100 years.

However, developers are not only looking for inherent strength, they will also be looking for other advantages that can be associated with this strength. With concrete pipes this could mean a number of things: it means that the product can be less affected by damage caused by jetting (with 5,000 psi jetting resistance) or rodent attack. Concrete pipes can also withstand impact damage caused by solid objects being carried through the system during floods and normal operation.  

Other advantages include resistance to degradation from heat or normal UV light. With advances in mix design, precast pipes manufactured today have resistance to attack form aggressive chemicals in the ground. This was proven at a recent “Partners in Innovation” research project conducted by BRE where concrete pipeline systems proved to be resistant to sulphates in the vast majority of soils in the UK.
