FloPlast Underground 270mm 90° Inlet Chamber Base

Specifications for Underground Drainage Pipes and Fittings

Our underground drainage systems are manufactured using high-performance, unplasticised polyvinyl chloride (PVC-U), a material known for its strength, durability, and chemical resistance. These components are specifically engineered for long-term use in demanding environments such as domestic, commercial, and industrial drainage networks.

Each product is carefully produced in accordance with relevant UK and EU standards for underground pipework, providing consistent quality and performance you can trust. The robust PVC-U construction offers excellent protection against corrosion, abrasion, and environmental stress—making it an ideal choice for modern drainage systems where reliability is key.

Benefits and Features of the PVC Drainage System

Designed for efficiency and ease of use, our underground drainage system offers a wide range of practical benefits. The lightweight pipework is easy to handle and install on-site, reducing both labour time and installation costs. Ideal for new builds or renovation projects, it’s perfectly suited for confined spaces, uneven ground, and sloped installations.

Key system features include:

• Precision-engineered pipe connections and fittings

• Watertight seals for leak prevention and system longevity

• Compatibility with above-ground and below-ground systems

• Low-maintenance materials that resist root intrusion and ground movement

This all-in-one solution provides a durable and dependable approach to managing foul water and wastewater drainage, helping to meet the demands of both residential and commercial builds.

Installation Tips for Long-Lasting Drainage Performance

For optimal performance and drainage efficiency, installation should begin at the lowest point of the system and progress upward to ensure proper flow direction. Before connecting pipes and fittings, clean all contact surfaces thoroughly to remove dirt or debris.

To achieve a watertight fit, apply a suitable silicone-based lubricant when assembling joints. Trenches should be prepared to the recommended depth, with a compacted granular bed to support and protect the pipework. Ensure pipes are properly aligned and backfilled according to industry best practices and site-specific requirements.

Following correct installation guidelines helps extend the life of the system and ensures compliance with building regulations.

Surface Water Control with Channel Drainage Systems

Surface water management is essential in outdoor spaces prone to pooling, flooding, or excess runoff. Our channel drainage systems offer a reliable solution for capturing and redirecting water from patios, driveways, walkways, garages, and landscaped areas.

Key features of our channel drainage systems include:

• Anti-slip grates to prevent slips in wet conditions

• Removable covers for easy cleaning and maintenance

• Durable design suitable for light domestic and commercial use

• Open channel profiles to maximise flow efficiency and debris clearance

With these systems in place, you can maintain dry, hazard-free surfaces around your property while reducing water damage risk to foundations and paving.

Kitemark-Certified for Trusted Quality

All drainage components in our product range are Kitemark-certified, ensuring they meet the strict safety, performance, and durability standards required in the UK. This independent certification confirms that our systems have passed rigorous testing for impact resistance, joint integrity, and structural strength.

Choosing Kitemark-certified products gives peace of mind that your drainage system meets recognised national benchmarks for quality and long-term reliability.

Storage, Handling, and Safety Guidance

To protect your investment and ensure reliable installation, it’s important to store and handle PVC drainage components with care. Avoid contact with strong solvents or aggressive chemicals that may weaken the material over time. Always store pipes in a cool, dry place, out of direct sunlight, to prevent UV-related degradation.

During transport and installation, avoid dragging or dropping components, which can cause cracks or damage to jointing ends. Proper handling helps preserve the integrity of the product and ensures smooth, trouble-free assembly on site.
