Attenuation Crates And Soakaway Systems

About

Attenuation Crates & Soakaway Systems Attenuation crates are the cornerstone of effective Sustainable Drainage Systems (SuDS), providing a high-capacity, space-saving solution for managing surface water runoff. Also referred to as soakaway crates, infiltration tanks, or stormwater crates, these modular units are essential for preventing flooding, protecting properties, and complying with modern building regulations. What are Attenuation Crates? These heavy-duty, interlocking plastic units are designed to create a subterranean void that can temporarily store (attenuation) or infiltrate (soakaway) large volumes of rainwater. Attenuation: The crates are wrapped in an impermeable membrane (liner) to hold the water temporarily before it is slowly released into the drainage system (often via a flow control device). This reduces the burden on public sewers during peak rainfall. Soakaway/Infiltration: The crates are wrapped in a permeable geotextile fabric, allowing collected rainwater to gradually percolate or "soak away" into the surrounding ground. Key Benefits of Our Crates Exceptional Void Ratio: Our crates offer a high void ratio (often over 95%), meaning a large amount of water storage is achieved with minimal excavation, making them incredibly efficient. Heavy Load Bearing: Designed for both domestic and commercial applications, including under driveways, parking areas, and landscaped zones. Modular and Easy to Install: The lightweight, interlocking design makes them fast and simple to assemble on-site, saving time and labour costs. Sustainable Drainage Solution: Essential for meeting local planning and environmental requirements for new builds and extensions. Choose the Right Crate for Your Project Whether you are looking for a domestic soakaway system for a new extension or a large-scale commercial attenuation tank for a housing development, we offer a range of sizes, strength ratings, and accessories, including: Attenuating Crate Bundles (complete with geotex
