Piling contractor GTL used more than 150 specially adapted screw piles for the new Wipeout roller coaster at Pleasurewood Hills in East Anglia.

The firm amalgamated its screw pile technology with reinforced concrete pile caps to construct the ride's foundations. In doing so it was able to overcome running sand and liquid mud to provide a foundation solution which used 80% less concrete than traditional methods. The ride, which opened in May, stands more than 116ft high and can carry 760 passengers per hour along the 900ft of twisted steel at speeds touching almost 50mph.
