Expert Drain Relining & Drainage Solutions in Blandford Forum, Dorset
Elderly residents at a sheltered housing scheme in Chescombe Court, Winterborne Whitechurch near Blandford Forum were facing persistent drainage issues caused by excess groundwater from a nearby river. The additional water was overwhelming the site’s drainage system, leading to repeated blockages and disruption for residents.
Recognising the urgency of the situation, the local council called in Maintain Drains — trusted drainage specialists covering Blandford Forum and the wider Dorset area — to deliver a long-term solution without major excavation.

The Challenge: Persistent Groundwater Drainage Issues
The primary issue at the housing scheme was groundwater infiltration. Dorset’s landscape and seasonal rainfall can place significant pressure on older drainage systems, particularly in low-lying areas around Blandford Forum.
Water from the nearby river was entering the pipework through cracks and displaced joints. This caused:
- Slow draining toilets and sinks
- Recurring blockages
- Strain on the overall drainage network
- Increased risk of structural pipe failure
Residents, many with mobility challenges, were left in a distressing situation and had to rely on portable toilets during peak disruption. A rapid yet minimally invasive solution was essential.
Our Solution: No-Dig Drain Relining in Blandford Forum
Rather than carrying out a full excavation — which would have caused significant disruption to elderly residents — we proposed drain relining, a trenchless repair method that reinforces pipes internally and prevents further groundwater ingress.
Drain relining creates a new structural lining inside the existing pipe, sealing cracks and restoring strength without digging up roads, gardens, or pathways.
Project Objectives
- Provide a long-term structural repair to prevent ongoing infiltration.
- Minimise disruption for vulnerable residents.
- Restore full drainage functionality as quickly as possible.
The Process: Step-by-Step Drain Repair
1. CCTV Drain Survey in Blandford
We began with a detailed CCTV drain survey to inspect the internal condition of the pipework.
This allowed us to:
- Identify cracks and joint displacement
- Locate exact infiltration points
- Assess structural integrity
- Determine suitability for relining
If you’re based locally, see our dedicated CCTV drain surveys in Blandford Forum page.
2. Drain Clearance & Preparation
Before relining, the pipework was thoroughly cleaned using high-pressure drain jetting. This removed silt, debris and residue to ensure proper liner adhesion.
3. Installing the Drain Liner
A resin-saturated liner was inserted into the damaged section of pipe, inflated and cured in place. Once hardened, it formed a seamless structural pipe within the original pipe — creating a watertight barrier against groundwater.
This method avoids the need for excavation repairs in most cases.
4. Final Inspection & Verification
A second CCTV inspection confirmed the repair was successful and the drainage system was fully operational.
The Outcome: Restored Drainage & Peace of Mind
Thanks to our trenchless drain relining expertise, the sheltered housing scheme’s drainage system was fully restored.
Key Results:
- No More Portable Toilets – Full drainage facilities reinstated.
- Minimal Disruption – No large-scale excavation required.
- Long-Term Structural Solution – Pipes now protected against further groundwater ingress.
- Positive Resident Feedback – Fast, professional and considerate service.
