Project London, United Kingdom

Forest Road

Development of brand new 353-bed student accommodation

Sector: Buildings

Installing 900mm-1500mm diameter to depths of up to 47m 

Technical Specifications

Pile Type: Bearing

Number of Piles: 39no.

Diameter: 900/1200/1500mm

Depth: Up to 47m

The Challenge

The project required the installation of 39no. 900/1200/1500mm diameter bearing piles to depths of up to 47m to support the development of student accommodation adjacent to an existing railway. London Underground specified that 15m of casing had to be installed to mitigate the egress of Bentonite into the surrounding tunnels at Blackhorse Road Station. 

The Solution

Martello installed the piles using an RH28 piling rig which had the ability to install and extract all casing diameters whilst achieving depths of up to 47m. The use of Ultrabore Bentonite to support unstable ground allowed for Martello to dig to 47m.
