Project challenges
Heavy London clay
Ground conditions are heavy London clay. This proved challenging in times of rain, both to maintain the project programme and the high level of tidiness expected during the works.
Access to the club’s compound is a single lane track, making delivery of materials slow and a challenge to manage.

Our approach
Complete drainage solution
The scope of work comprised the following:
- Installation of 160mm perforated main drainage, to a maximum depth of 1.5 metres
- Lateral drainage within fairways was installed at 5 metre centres. These comprised 80mm perforated pipe within trenches filled with gravel and an approved sand /soil rootzone at surface level
- Secondary drainage was in the form of sand slitting, installed at 1 metre centres, to a depth of 300mm and width of 50mm. The slits were installed perpendicular to the lateral drainage, creating a grid of drainage over the area
- All trench lines were seeded with successful follow-on maintenance undertaken by the club.

Outcomes
In play all year round
Feedback from the greenkeepers and club members has been very positive. This traditionally wet fairway is now in play all year round.
