Piling/Diaphragm Wall

Piling and ground improvement works underpin the performance of many key New Zealand structures. Firth has a long track record on major infrastructure and commercial projects in manufacturing concrete mixes suitable for a variety of pile types; including bored and tremie piles, retaining piles such as diaphragm walls and central flight auger or contiguous piling. 

Our expertise in this field allow us to deliver on both the high-quality concrete and top flight service required for this work. Our piling mixes can be tailored for extended workability and stability required for high spec piling operations.
