A hidden drainage system that keeps us safe

This, combined with rising sea levels, a growing population and built environment has increased the importance of our drainage systems.

Often out of sight and mind, we are dependent on these systems working to reduce the chances of flooding and the misery, the flood water causes when flooding happens.

Precast concrete drainage is not something that springs to mind as a superhero, but with the increase of extreme weather events, our UK surface water and foul water sewers are overworked and under maintained.

Reducing surface water and allowing us to travel safely, we rely on precast concrete gullies and gully covers to collect the water from roadways, which is then conveyed along the system, to the manhole (consisting of a seating ring, cover slab and chamber ring) and into the pipeline that acts to hold and store the rainwater, until its released further into the drainage system.

Gullies and Gully Covers
Designed to aid the removal of rainwater, floodwater and debris from roadways, gullies help to keep the roads clear and safe for road users.

Used throughout the UK road network, the gully cover sits under the gully grating on top of the gully itself and is designed to discharge surface water from roads and highways, where large volumes of surface water can build-up and convey it into the system.

Seating Rings
Offering a great alternative to engineering bricks, concrete seating rings, also known as adjusting units, provide an access point into surface water drainage systems, sitting on the cover slab, they help to adjust the manhole to the desired depth.

Cover Slabs
Available with different access sizes, dependant on application, heavy-duty cover slabs sit on top of chamber rings as a lid or biscuit. Made from high-quality precast concrete ensures that they can withstand heavy loads, making them a popular choice for roads, rail, housing developments, water and infrastructure projects.

Installed quickly, precast concrete cover slabs enhance security for the manhole by preventing unauthorised access to the underground network and a long lifespan provides a reliable performance over time.

Chamber Rings
Precast concrete manhole chamber rings are used to provide ladder, step or rung access to the below ground foul and surface water management drainage system and are circular in shape.

Delivered ready to install, chamber rings are designed to withstand infiltration, attack by groundwater and corrosive environments and have a design life of 120 years, making them a real sewer superhero.

Pipes
The inherent strength of a concrete pipe ensures its shape retention, allowing for even load distribution, easy installation and can hold surface water until it conveys I into the network.

Secure drainage systems
We canÂ’t stop the rain, however stormwater management and drainage solutions are the key to reducing floodwater and flooding.
