Project Introduction
In July 2024, a new residential development of 12-13 houses in Killarney required a reliable stormwater solution with soakaway crates. The site featured a large car park at the front of the estate, necessitating a robust stormwater management system to comply with local planning regulations. A 120m³ geocellular attenuation system was installed to capture and gradually release rainwater into the drainage network. This approach ensured effective stormwater control, enhancing safety and functionality during heavy rainfall.

THE CHALLENGE
The project required a soakaway crates system capable of managing runoff from both the housing units and the sizeable car park. The solution needed to meet stringent local regulations, operate efficiently, and provide long-term reliability.
The Installation
The project was completed in three key phases:
Phase 1:
- Excavating the site to create a 30m x 5m x 2m space for the tank.
- Preparing the site with a level, compacted gravel base.
Phase 2:
- Installing a “sandwich” membrane system (geotextile, waterproof membrane, geotextile).
- Assembling soakaway crates in two rows, securing side panels with clips.
- Enclosing the crates with the same membrane system and connecting inlet/outlet pipes with a vent pipe.
Phase 3:
- Backfilling the tank with soil and gravel for stability.
