Drainage Contractors Across Sussex, Surrey and Kent
CJ Groundworks installs, repairs and upgrades foul-water and surface-water drainage for homes, extensions, new developments, farms and commercial properties across Sussex, Surrey and Kent.
With more than 35 years of groundworks experience, our family-run team can manage excavation, pipework, chambers, gullies, soakaways, drainage repairs and associated reinstatement.
We assist with planned drainage projects and investigate problems such as standing water, damaged underground pipes, overflowing chambers and ineffective surface-water systems.
Every quotation is based on the site, access, existing drainage arrangement and agreed scope of work. Where surveys, designs, approvals or specialist equipment are required, these will be identified before work starts.
/ Our Services
Domestic and Commercial Drainage Services
We provide drainage installation, investigation and repair services for homeowners, landlords, builders, developers and commercial property owners.
The work is tailored to the site and may involve a single repair or a broader package covering excavation, new pipework, chambers, drainage connections and reinstatement.
Drain Installation
We install below-ground drainage for extensions, new homes, outbuildings, commercial premises and external improvement projects.
The work can include:
- Foul-water drainage runs
- Surface-water drainage
- Separate foul and rainwater systems
- Inspection chambers and access points
- Gullies and channel drainage
- Soil and waste connections
- Soakaways and infiltration systems where suitable
- Attenuation crates and flow-control groundwork
- Drainage beneath extensions and new buildings
- Connection preparation for approved discharge points
- Backfilling and reinstatement
Pipe diameters, gradients, chamber positions and discharge arrangements should follow the agreed drainage design and applicable project requirements.
Where a soakaway or infiltration system is proposed, the site’s suitability should be established before installation rather than assumed from the available space alone.
CCTV Drain Surveys
A CCTV drain survey allows accessible underground pipes to be inspected without immediately excavating the site.
Surveys can help identify:
- Cracked or displaced pipe joints
- Collapsed or deformed sections
- Root ingress
- Scale, debris and other obstructions
- Poor connections or changes in pipe condition
- Areas requiring further investigation or excavation
CCTV inspection may be useful when investigating repeated blockages, planning building work or reviewing drainage before a property purchase.
Where included in the service, the customer will receive recorded footage or images together with a summary of the findings and recommended next steps.
Drain Repairs
Damaged drains can cause repeated blockages, leaks, subsidence around the pipe or wastewater escaping into the surrounding ground.
Depending on the fault and access, repair work can include:
- Excavating damaged sections
- Replacing cracked, collapsed or displaced pipework
- Renewing defective joints and connections
- Rebuilding or replacing inspection chambers
- Correcting localised gradient problems
- Improving access for future maintenance
- Backfilling and reinstating the affected area
The repair method will be based on the condition and location of the pipe. Where excavation is likely to cause unnecessary disruption, we will confirm whether a specialist no-dig repair should be considered.
Drain Jetting & Cleaning
High-pressure water jetting can clear many obstructions and remove deposits from suitable drainage pipes.
It may be used to address:
- Grease and organic build-up
- Silt and loose debris
- Scale deposits
- Some root intrusion
- Recurring restrictions in accessible pipework
Jetting restores flow but does not repair structural defects. If a drain blocks repeatedly, a CCTV inspection may be recommended to check for damaged joints, poor gradients, root ingress or collapsed pipework.
We will assess the drainage arrangement and confirm whether jetting is appropriate before work begins.

When Should You Call a Drainage Contractor?
Arrange a drainage assessment if you notice:
- Water draining more slowly than usual
- Gurgling toilets, sinks or pipework
- Persistent sewage or stagnant-water smells
- Repeated blockages
- Water pooling on patios, drives or lawns
- Overflowing gullies or inspection chambers
- Damp or unusually soft ground above a drain
- Cracks or settlement around a chamber
- Wastewater backing up into the property
These symptoms can have several causes, including a local blockage, damaged pipe, ineffective soakaway, incorrect gradient or overloaded drainage system.
We will gather information about the problem, inspect the accessible drainage and explain the most appropriate next step.
