Three recent completed projects in Margaret River Western Australia have revealed that not only good wine flows from the region. Screwpile Australia were engaged on separate occasions to provide preliminary pile probe testing to determine that 25 and 50 tonne screwpiles were required at  varying depths of up to 15 metres. The site was well known for its spring water and very loose clays.

Testing indicated that the depth of the water and clays was well beyond that which would normally be expected. The photo to the upper left graphically shows clay with the consistency of custard flowing freely up the pile after installation due to hydrostatic water pressures.  A total of 60 x 50 to 25 tonne x 15 metre deep  screwpiles were installed in just 4 days, all without intrusion or structural disturbance to adjoining businesses and residential buildings.

In the latest project  250 x 6 tonne screwpiles  up to 4.5m deep were installed for a new holiday resort.  Screwpiles were specified due to the existence of peat and organic matter at depth.  A purpose designed bobcat with an extension boom took 4.5 days to install the piles.
