CSR Pipe (Composite Steel Reinforced pipe) is a modern alternative to traditional concrete pipe for large-diameter drainage systems.
Composite Steel Reinforced pipes combine a steel reinforcement core with high-density polyethylene (HDPE). This provides the strength needed for infrastructure projects without the environmental impact, weight, or handling challenges of concrete.
How CSR Pipe is Made
CSR pipe is built around a steel reinforcement structure, which is then encased in HDPE.
- The steel core provides the structural strength needed to withstand ground loads and heavy traffic
- The HDPE outer layer protects against corrosion and harsh underground conditions
The pipes also feature a push-fit joint with an integral seal. This helps prevent leaks and protects the drainage network over time.
Why Consider CSR Instead of Concrete?
Strength is not the only factor when designing drainage and infrastructure projects. Installation time, site safety, and carbon impact are also important when choosing materials.
Many developers are now looking beyond concrete. CSR pipe offers a practical and more sustainable alternative.
Compared with traditional concrete pipe, CSR systems offer:
- Reduced weight, making pipes easier to transport and handle
- Faster installation, helping to reduce programme time on site
- Fewer transport movements, simplifying site logistics
- Lower embodied carbon
- A design life of 120+ years
Designed for Large Diameter Gravity Drainage
Aquaspira CSR pipes come in a range of sizes and are designed for use in a wide range of drainage projects, including:
- Water utility infrastructure
- Residential and commercial developments
- Highways and major infrastructure projects
- Battery Energy Storage Sites (BESS) and other Pollution Containment applications.
As practical alternatives to concrete become more widely available, developers are increasingly choosing Aquaspira solutions that prioritise efficiency, durability and carbon reduction. CSR pipe is a durable and efficient alternative to traditional concrete systems. It supports modern drainage infrastructure.
