Manufactured from high-quality materials, this base unit is built to withstand the challenges of underground environments, including pressure, moisture, and environmental stress. Its robust design ensures long-term reliability with minimal maintenance requirements.

Seamless Integration with FloPlast Components

Compatible with a wide range of FloPlast fittings, this base unit allows for easy integration into existing systems or new installations. Its versatility makes it an excellent choice for customised drainage solutions across different project requirements.

For a durable, efficient, and versatile solution to enhance your underground drainage system, choose the 270mm Deep Base Unit. Its superior construction and compatibility with FloPlast components ensure reliable performance and effective water management in any application.

Specifications for Underground Drainage Pipes and Fittings

Our underground drainage systems are built using tough, high-grade unplasticised polyvinyl chloride (PVC-U), a trusted material in the construction industry for its long-lasting durability and resistance to chemical and environmental stress. These systems are designed to perform reliably in both residential and commercial drainage applications, as well as in more demanding industrial installations.

Every component is manufactured to meet relevant UK and European standards, ensuring consistent product quality and dependable performance. Thanks to its non-corrosive nature and excellent structural integrity, PVC-U offers lasting protection against soil pressure, weather exposure, and internal flow abrasion—making it a solid foundation for any underground pipework system.

Why Choose Our Underground Drainage Systems?

Designed for both performance and practicality, our PVC drainage systems provide a reliable and easy-to-install solution for wastewater management. Whether you're working on a new construction site or upgrading an older system, these components simplify the installation process without compromising on strength or efficiency.

What makes our system stand out:

 

  • Precisely moulded joints and couplings for secure, tight-fit connections

  • Leak-resistant seals that support long-term water flow performance

  • Lightweight structure for easier transportation and faster installation

  • Compatible with surface and sub-surface drainage systems

  • Low-maintenance design that resists tree root intrusion and ground movement

Whether it’s a housing development or a commercial site, these systems deliver dependable performance with minimal upkeep.

Best Practices for Installing PVC Drainage Systems

Proper installation is key to a smooth-running and long-lasting drainage network. To get the most out of your system, begin by laying pipework from the lowest drainage point upward. This ensures proper alignment and flow direction throughout the run.

Clean all connecting surfaces before assembly to avoid debris interference. A silicone-based lubricant can be used during jointing to create a secure, watertight seal. Prepare the trench with a compacted granular base to provide stability and support for the pipeline. Once pipes are laid, carefully backfill with suitable material, avoiding any sharp debris that may damage the system.

Adhering to installation guidelines ensures efficient operation and compliance with current building standards.

Surface Drainage Made Easy with Channel Systems

Managing excess surface water is essential for both safety and structural protection. Our channel drainage systems are specifically designed to capture and divert surface runoff from common outdoor areas such as patios, garages, garden paths, and driveways.

Notable features include:

 

  • Slip-resistant grating for enhanced safety in wet weather

  • Removable access grates for straightforward maintenance

  • High-flow design to prevent pooling and waterlogging

  • Durable construction suitable for light traffic and domestic use

Installing a proper surface water drainage system helps protect buildings and hardscapes from water-related damage, while also creating safer walking and driving surfaces.

Built to Standard: Kitemark-Certified Components

All products in our underground drainage range carry the Kitemark certification—a recognised symbol of quality, performance, and safety in the UK. This guarantees each component has passed independent testing for factors like pressure resistance, material strength, and structural durability.

With Kitemark-certified parts, you can be confident you're using materials that meet the highest industry standards, offering peace of mind on both compliance and long-term performance.

“Very impressed this time around!!! (disappointed with communication and delivery in first lockdown) and left a negative review which I updated after delivery. I can now understand all the good reviews before the pandemic. Still the cheapest by far and the products are spot on. I've just placed another order - Thank you keep up the good work”
