The cost of piling is dependent on the size of the pile, depth, and soil properties. Economies are generated when multiple piles are driven.
Common Types of Scenarios:
- New house slab
- Continuous footing added support or uplift
- Base for free standing light poles, signs etc.
- Anchoring pins/ soil nails.
- Retrofitted blade piles to support sinking foundations due to poor soil bearing capacity.
In a domestic house type scenario Ball park you would expect to pay approx $700/ underpinning pier, when driven in multipies as opposed to about $1000 /concrete pier. Add in Establishment cost on site approx $1000+gst. Remember you don’t have the issue of having to get rid of spoil which is a cost saver.
If a pier is required for jacking purposes the cost will increase as suitable brackets are required
Pier Design for structure support $500+gst
If certification required by Engineer add $500+gst
