Our services

We offer a complete range of soakaway services, including:

• Soakaway design – tailored solutions to meet the specific drainage requirements of your property.
• Trench soakaways – gravel-filled trenches that allow water to percolate gradually into surrounding soil, ideal for smaller areas or linear drainage needs.
• Chamber soakaways – modular, high-capacity chambers for larger properties or commercial sites.
• Installation and connection – excavation, placement, backfilling, and integration with your existing drainage system.
• Maintenance and inspections – ensuring efficient operation and ongoing compliance with regulations.

All work is carried out by skilled engineers using modern equipment, delivering reliable and long-lasting surface water management.

Installation process

Our soakaway installation process is carefully managed from start to finish:

• Site survey and assessment – evaluating soil type, water flow, and drainage requirements.
• Design selection – choosing the most suitable soakaway type for your property or project.
• Excavation and installation – preparing the site, installing the soakaway structure, and connecting to existing drainage.
• Backfilling and testing – ensuring correct operation and compliance.
