The job
Building a storm retention tank with a capacity of 15,000 cubic metres to hold water in a storm event, on Blackpool Road just north of Preston.
Our involvement
Engineering management
The challenge
The area was a flood plain so it was very soft ground making it difficult to anchor the tank and prevent it from lifting.
Our solution
We used 1900 piles driven at 16 metres depth for the intermediate piles and 21 metres depth for the pyramid piles [check]
