When surface quality and resistance matter most, Polypipe Civils delivers engineered systems that keep sports environments performing at their peak
Our engineered systems manage water efficiently beneath pitches, tracks, and training grounds, ensuring stability, longevity, and optimal surface conditions in all weather. With proven resilience and precision-built performance, Polypipe Civils delivers the reliable underground infrastructure that helps every surface stay at its best.
Broad, Shallow Attenuation
Whether used for community fields, school grounds, or professional training pitches, Permavoid supports resilient, all‑weather sports surfaces that manage stormwater sustainably while meeting modern performance demands.
Installed beneath both natural and artificial turf, Permavoid enables rapid drainage, shallow attenuation, and reliable water movement throughout the system. These capabilities prevent waterlogging, reduce surface downtime after heavy rainfall, and support the long‑term performance of the playing surface. Its engineered structure also eliminates the need for deep excavations or heavy construction plant, making it a practical and sustainable choice for community clubs, schools, and professional sports facilities alike.
Football, Rugby and Hockey
Permavoid is an easy-to-install, sustainable and cost effective combined sports surface and water management system for the full range of football, rugby and hockey pitches with either synthetic or natural surfaces.
It delivers strong sports‑performance benefits by providing a factory‑manufactured, approved sub‑base that ensures a fully levelled pitch with excellent drainage characteristics. This unique patented system enhances consistency in ball behaviour and player‑surface interaction, helping create true all‑weather playing conditions. It also meets international sporting standards, including approval by NOC, NSF and FIFA, making it suitable for professional‑level facilities as well as community and educational pitches.
Lightweight Build For Rapid Installation
Tennis Surfaces
Tennis surfaces, whether clay, hard courts, or synthetic turf, demand absolute consistency in play, stability underfoot, and fast, effective drainage.
Permavoid’s engineered geocellular system delivers a high‑performance sub‑base that transforms the reliability and longevity of modern tennis courts.
Beneath clay or hybrid surfaces, Permavoid’s ultra-efficient capillary drainage rapidly removes excess water, reducing downtime after heavy rain and preventing surface washout. On hard or synthetic courts, the system eliminates standing water and supports a stable, smooth finish, helping maintain playability even in challenging weather conditions.
Equestrian
The Permavoid system has been used for equestrian events large and small, including the London 2012 Olympic event at Greenwich Park, where complex performance and construction criteria were achieved with great success. The Permavoid system is completely 'demountable' so ideally suited to temporary events as well as permanent installations.
The Permavoid system can be installed without excavation when required and easily adapts to uneven ground while still meeting international equestrian event tolerances. It incorporates surface‑water management and rainwater‑harvesting features, and works effectively on both ground‑level and raised‑platform installations, all while aligning with sustainable drainage best practice.
