Our Drainage Services
With years of experience in the industry, we use advanced techniques and top-grade materials to ensure your drainage system functions efficiently and complies with all UK building regulations.
Full & Partial Drain Excavations
If only a specific section of your drainage system is damaged, we offer partial drain excavations to replace or repair the affected area without the need for a full system overhaul.
Complete Drain Replacement – Ideal for collapsed or heavily damaged systems.
Upgrading Old Drainage Systems – Installing modern, durable pipes.
New Drainage System Installation – Custom solutions for new builds and renovations.
Severe Structural Damage Repairs – Addressing ground movement, subsidence, or heavy traffic wear.
Our Drain Excavation Process
Initial Consultation & Site Assessment
- We start by conducting a comprehensive site assessment, reviewing any existing drainage plans and understanding the history of the problem.
- Our team discusses the symptoms of the drainage issue with you to identify the extent of the problem.
- If necessary, we recommend a CCTV drain survey to pinpoint the exact location and severity of the damage before excavation.
CCTV Drain Survey & Pre-Excavation Investigation
- We use state-of-the-art CCTV drain cameras to inspect the inside of your drainage system.
- This allows us to identify collapses, cracks, misaligned joints, root intrusions, or severe blockages.
- The survey helps us determine the precise depth, location, and scope of excavation needed, reducing unnecessary disruption.
Planning & Safety Preparation
- Once we confirm the need for excavation, we create a detailed work plan, considering factors such as:
• The size and depth of the excavation
• The location of underground utilities (gas, water, electricity)
• The structural integrity of surrounding areas
- We conduct a risk assessment to ensure safe excavation practices.
- If needed, we liaise with local authorities for permits and approvals, particularly for public areas or roads.
Excavation & Drain Repair/Replacement
- Using specialist excavation equipment, we carefully dig out the affected drainage area.
- Depending on the severity of the issue, we perform either a:
• Full Drain Excavation – Removing and replacing an entire drainage system.
• Partial Drain Excavation – Replacing only the damaged or collapsed sections of pipe.
- We use high-quality, durable materials such as PVC, clay, or cast iron pipes, ensuring longevity and compliance with UK building regulations.
- We ensure proper pipe alignment and secure connections to prevent future leaks or blockages.
Reinstatement & Site Restoration
- Once the new drainage system is in place, we backfill the excavation site with appropriate materials.
- We carefully restore the surrounding area, including:
• Replacing soil and landscaping in gardens.
• Re-laying driveways, pavements, or tarmac if excavation occurred in a hard surface area.
• Repairing any disrupted structures (e.g., fences, patios, or pathways).
Final Testing & Inspection
- After installation, we carry out comprehensive drain testing to ensure proper flow and function.
- We perform CCTV drain inspections to verify that the pipes are aligned, sealed, and free from defects.
- We check for leaks, blockages, and water flow efficiency, making any final adjustments if needed.
