Emergency Drain Clearance
Our emergency drain clearance service rapidly addresses blockages and drainage issues, ensuring minimal disruption. Using advanced combi jetting technology, we clear obstructions caused by debris, grease, or root ingress. Clients benefit from 24/7 availability and a fleet equipped for swift response across Kent and the South East.
CCTV Surveys
CCTV surveys provide detailed visual inspections of drainage systems, identifying cracks, blockages, or structural issues. Our high-resolution cameras map pipelines accurately, generating reports with actionable recommendations. This service supports informed decision-making for repairs or renovations, ensuring compliance and long-term system reliability.
Sewer Repairs
We offer comprehensive sewer repair solutions, including pipe relining and joint sealing. Our methods minimise excavation, reducing costs and environmental impact. Repairs are executed with durable materials and advanced techniques, ensuring systems meet regulatory standards and withstand heavy usage in both urban and rural settings.
Pump Station Installation
Our pump station installation service includes design, setup, and maintenance of systems for efficient wastewater management. Tailored to client needs, installations feature robust components and smart monitoring technology. Regular maintenance ensures optimal performance, preventing failures and extending the lifespan of critical infrastructure.
Combination Jet Vac Cleaning
Combination jet vac cleaning utilises high-pressure water and vacuum systems to remove stubborn blockages and debris. This method ensures thorough cleaning of drains and sewers, preventing future issues. Ideal for commercial kitchens and industrial sites, it restores flow capacity and maintains hygiene standards efficiently.
