Overburden Drilling EXentric (ODEX) piles are typically used in challenging ground conditions, where pile capacity is generated from a rock socket beneath unsuitable overlying strata.
Piles are constructed by progressing steel casing through unstable overburden soils into the head of bedrock. A rock socket is then formed using rotary percussive ‘open-hole’ drilling. Arisings are removed from the borehole through the use of compressed air flush.
Once the rock socket is formed, piles are concreted and reinforcement cage is inserted.
This method of piling can be used to manage challenging ground conditions, including mine-workings, cobbles and boulders or layered / laminated rock.
