True Specialists in Residential Drainage

"We only do drainage and foundations – we are not general builders trying to 'have a go'. This means we see the tricky problems every week that most builders only encounter once every few years."

With over 18 years specialising in residential foul and surface-water drainage, our core groundwork team brings a combined 30+ years of technical engineering expertise to your property. Drainage requires precision, compliance, and an uncompromising approach to quality.

Your peace of mind is paramount. Every member of our dedicated drainage crew is fully certified, holding CSCS cards (minimum Skilled Worker level) and NRSWA Street Works accreditation for any works affecting public highways. Furthermore, we operate under £3 million Public & Liability insurance, with specific Contractors cover.

Professional Materials & Testing

We don't cut corners on materials or compliance. Our installations are built to last and guaranteed to pass stringent Building Control inspections:

  • Soakaway Systems: Installation of industry-leading Marsh or Klargester soakaway crates.
  • Seamless Connections: We use Hepworth or Fernco adaptors for structurally sound connections to old clay pipes.
  • Rigorous Testing: Comprehensive pressure testing, pre/post-install CCTV surveys, and air/water tests prior to handover.

Foul & Surface-Water Systems

Whether you require entirely new installations or rerouting for an extension, we expertly manage residential foul and surface-water drainage. We utilise premium 110mm and 160mm Osma/Polypipe materials to ensure a durable, compliant flow.

If your project crosses existing utility lines, we seamlessly handle the Build-Over Agreement applications, dealing with the paperwork and utility companies so you don't have to.

Soakaways & System Modernisation

Effective water management is critical to protecting your property's foundations. We specialise in the excavation and installation of high-capacity Marsh or Klargester soakaway crates wrapped in professional geotextiles.

For properties with legacy infrastructure, our engineers are adept at modernising systems. We use high-quality Hepworth or Fernco adaptors to safely and securely connect new PVC systems to older, fragile clay pipes.

Service Process

Inspection to Final Sign-Off

1. Surveys & Quotation

We conduct a free site survey and drainage appraisal (usually within 48–72 hrs of your enquiry), followed by a detailed written quotation. If dealing with existing drains, a pre-start CCTV survey and level survey will be completed.

2. Preparation & Installation

If needed, we completely handle the Build-over agreement application. Once approved, our certified engineers begin the installation, keeping you informed with daily photos and clear progress updates.

3. Testing, Sign-Off & Handover

We conduct stringent pressure testing, a CCTV post-install survey, and air/water tests to ensure absolute integrity. We arrange the Building Control inspection, ensure it is passed, and formally hand over the completed works.
