Depth varies by service type, but many domestic utility ducts are laid between 450–600mm below ground level. Local guidance and utility provider requirements should always be checked before installation.
Solutions for Sewer Systems, Underground Ducting and Site Drainage
Concrete reinforcement, ducting and drainage components form the core of this category, covering products used to support ground stability and manage water movement on construction sites. Items such as Land Drainage, Line Drainage and Sewer Pipe & Fittings help direct surface and subsurface water safely away from structures, reducing the risk of saturation or erosion. These products are commonly installed alongside Geotextile & Geogrid materials to improve soil separation and load distribution in both small and large groundwork projects.
This category also includes protective elements for access points, with Manhole Covers & Grates offering durable solutions for inspection chambers and utility openings. These are often used with Manhole Lifting Keys to ensure safe installation and maintenance access. Gas membranes and related accessories provide support in areas where protection against ground gases is required, while Waterproofing & Tanking products help control moisture around foundations and retaining walls.
Many of these components work in combination with other building materials, such as concrete kerbs and foundation products, supporting tasks like forming driveways, preparing footings or creating service routes. Underground Ducting systems can also be used with electrical or telecom supplies to create protected underground conduits, while reinforcement products help maintain structural strength in poured concrete applications. The broad range of materials allows flexibility across both above‑ground and below‑ground groundwork tasks.
Civils & Groundwork FAQ's
Geotextile is often placed beneath gravel to reduce mixing of soil and aggregate, helping maintain a stable surface and limiting future rutting. It also improves load separation where soft ground is present.
When a manhole is located in a trafficked area such as a driveway, a cover rated for heavier loads, typically class B125 or stronger, should be selected to support vehicle weight.
Membranes are commonly rolled or sheet applied to clean masonry or concrete surfaces. Joints are sealed, and care is taken to avoid punctures before backfilling to ensure consistent moisture protection.
A compacted granular bedding, often 10mm or similar, is commonly used to support the pipe evenly and reduce pressure points. Bedding should be level and free of sharp stones that could damage the pipe wall.
