Every drainage system tells a story — especially when things go wrong. At Portsmouth Drains24, our engineers tackle everything from minor blockages to complex collapsed drains beneath driveways, gardens, and commercial sites. In this post, we share several before-and-after case studies showcasing how professional repairs transform damaged systems back to full working order.
Whether it’s blocked drains in Portsmouth, root intrusions, or Buchan trap replacements, our team uses modern, non-invasive methods that save property owners both time and money.
Case Study 1 – Collapsed Drain Repaired with CIPP Lining
A homeowner in Southsea reported repeated blockages in their kitchen drain. A drain survey in Portsmouth using CCTV revealed a collapsed clay pipe caused by ground movement.
Before: Water backing up into the kitchen with foul smells.
After: Using CIPP lining, we restored the pipe’s structure without excavation — sealing cracks and preventing further damage.
✅ Result: Zero disruption to the property and a 25-year-guaranteed repair.
Case Study 2 – Root Removal and Re-Lining in Cosham
Tree roots had infiltrated an aging drain network serving a semi-detached property. Over time, these roots created multiple fractures in the pipework.
Before: Frequent flooding and gurgling noises from the bathroom.
After: Portsmouth Drains24 engineers used high-pressure jetting to clear the roots, followed by patch lining to reinforce weak sections.
✅ Result: Fully restored flow and improved drainage performance.
Case Study 3 – Buchan Trap Removal in Fratton
Many Victorian and Edwardian homes across Portsmouth still contain old Buchan traps — an outdated feature designed to block sewer gases. Unfortunately, these traps are notorious for catching debris and causing blockages.
Before: Water pooling in the garden and slow drainage in bathrooms.
After: The Buchan trap was removed, replaced with a modern inspection chamber and PVC pipework, ensuring free-flowing drainage for decades to come.
✅ Result: Improved system access for future inspections and maintenance.
Why Professional Drain Repairs Matter
Ignoring drainage issues can lead to severe structural problems — from subsidence to internal dampness. Regular drain surveys in Portsmouth help identify hidden faults early, while professional repair methods such as patch lining or full CIPP relining offer long-term protection against repeat failures.
Common warning signs include:
- Persistent bad odours
- Slow-draining sinks or toilets
- Gurgling noises
- Localised flooding outdoors
If you notice any of these, it’s time to call in the experts.
