Trenching Services in South of Wales

A properly dug trench is essential for the long-term success of any underground service. We provide expert excavation work for homeowners, builders, and commercial clients across South Wales for projects such as:

• New Drainage Installation: Laying new foul and surface water drainage pipes for property extensions, new builds, or system upgrades.
• Water Pipe Replacement and Installation: We excavate trenches to the required depth for new water main connections or to replace old, leaking lead pipes.
• Utility Cable Ducting: Creating safe, secure trenches for the installation of armoured electrical cables, fibre optic broadband, or other communication lines.
• Gas Pipe Trenching: We work alongside certified gas engineers to provide the necessary excavation work for new gas pipe installations, ensuring all safety protocols are followed.
• Soakaway and Septic Tank Groundworks: All groundwork required for the installation of septic tanks, treatment plants, and land drainage systems like soakaways.

While it might seem straightforward, digging a trench carries significant risks. The ground could be hiding live electric cables, gas pipes, or water mains. Striking one of these can be incredibly dangerous and lead to expensive repairs and utility outages. Our team uses specialist equipment to locate these services before we even break ground. We also have the right tools to work efficiently and ensure the trench is structurally sound and dug to the correct depth for the required installation.

The depth required for a trench depends entirely on what is being installed. For example, water pipes in the UK need to be laid at a minimum depth of 750mm to protect them from frost. Drainage pipes have different requirements, as they must be laid with a specific gradient or 'fall' to allow waste to flow away effectively. We carry out all excavation work in line with current building regulations and the specific needs of your project.

Absolutely. This is a non-negotiable part of our safety process. We use Cable Avoidance Tools (CAT) and signal generators to scan the proposed excavation area thoroughly. This allows us to identify and mark the location of most buried utilities, so we can work safely around them.

We understand that you want your property returned to normal. Our service includes careful reinstatement of the ground after the work is finished. This involves backfilling the trench in layers and compacting the soil correctly to prevent sinking. While some settlement can occur over time, especially with deep excavations, we take every step to leave the surface level, tidy, and ready for turf, seed, or paving to be put back.

We provide a flexible service to suit your needs. For drainage and water pipe work, we manage the entire project from excavation to installation and connection. If you need a trench for another utility, like a gas pipe or an armoured cable, we are happy to work with your chosen gas engineer or electrician. We can provide the expert excavation and backfilling service, leaving them to complete the final installation.
