Our Drainage Installation Process & FAQs
How Our Drainage Installation Works
Every drainage project is different, so we take a practical, site-specific approach to ensure the right solution is installed correctly and efficiently.
1. Initial Assessment & Site Survey
We assess the site, existing drainage (if applicable), and ground conditions to determine the most suitable drainage solution for your property or project.
2. Drainage Design & Planning
Based on the assessment, we plan the layout for foul water, surface water, or soakaway systems, ensuring correct falls, pipe sizing, and discharge points.
3. Excavation & Installation
Our team carries out the required excavation, installs drainage pipes and systems, and ensures everything is laid correctly for long-term performance.
4. Backfilling & Reinstatement
Once installed, trenches are backfilled and compacted, and surfaces are reinstated where required to leave the site safe and tidy.
5. Final Checks & Completion
All works are checked to ensure proper flow and performance before the project is signed off.
