Why It Matters
Groundworks Done Right — Once
Underground drainage infrastructure is invisible once installed — which makes quality of workmanship impossible to verify after the event. Shortcuts taken during groundworks inevitably resurface: inadequate falls cause standing water, incorrect backfill leads to settlement, and non-compliant connections create problems at inspection or when properties change hands.
DrainCare Direct's groundworks division operates to the same standards on every job — regardless of size. Utility scanning before every dig. Structural backfill as standard. Full surface reinstatement to match the existing finish. Building Regulations compliance documented and signed off. These are not options — they are how we work.
From a single drainage connection for a house extension to a phased underground network replacement across a school campus, our civil engineering team brings the same rigour and accountability to every project we take on.
Our approach
Every groundworks project begins with a full site assessment — and where existing drainage is involved, a CCTV survey before any ground is broken. We do not guess at what is underground. We survey it, map it, and design around it.

Case Study Focus
New Drainage System Installations
Whether you are connecting a new residential extension, installing drainage for a commercial development or replacing an entire below-ground network, the quality of the installation determines the long-term performance of the system. DrainCare Direct designs and installs drainage systems that are built to last — compliant with Approved Document H and water authority adoption standards where applicable.
Every installation begins with a site assessment and, where existing drainage is present, a CCTV survey to confirm connection points and system condition. We design for correct falls, access requirements and connection compatibility before any ground is opened.
On completion, we backfill and compact to specification, carry out a CCTV sign-off of the installed pipework and provide as-built drainage records for your Building Control submission, insurance records or future reference.
Case Study Focus
Excavation & Underground Pipe Replacement
When CCTV survey identifies collapse, severe root intrusion or irreparable structural damage, excavation is the only route to a permanent fix. DrainCare Direct provides controlled excavation across all property types — hand-dug around utilities and foundations, mechanically assisted where access permits, and always within a clearly defined safe working zone.
We do not excavate blind. Every dig begins with a utility scan and a clear scope of the pipe runs to be accessed — informed by the CCTV condition report and any available drainage records. This approach eliminates the risk of accidental damage to live services and ensures the excavation footprint is kept to the minimum necessary.
Following replacement, we backfill in approved granular layers to prevent settlement, and fully reinstate the surface — whether that is a residential driveway, a commercial car park or a school playground — to match the original finish.
