Bored Mini Pile Retaining Wall

This urban development situated in Central Edinburgh required specialist piling methods to enable the construction of a basement for the new building between existing properties.

Traditional underpinning methods were not possible as all works were to be undertaken in the Client’s own property boundary.

MG Piling proposed and designed a cantilever mini pile wall solution allowing retaining of soil beneath the neighbours properties and allowing excavation to form the basement.

Piles were socketed into rock 2.5 metres.

They are designed to resist tension and compression loads to allow steelwork frame to be constructed on this wall. Mini piles were formed using 220mm diameter permanently cased odex simultaneous drilling and casing.

The reinforcement comprised grade L80 tubular steel.
