Sheet Piling
Sheet piling consists of a series of panels with interlocking connections driven into the ground using impact or vibratory hammers to form an impermeable barrier. They are commonly used where high load bearing capacity is required in soft or wet ground and where there is a danger of ground subsidence. Sheets can be made from a variety of materials such as steel, vinyl, plastic, wood, precast concrete and fibreglass. Steel is the most common in New Zealand and it can be used uncoated (black), galvanized or epoxy coated.
Sheet piling has been a proven technology within the construction industry for many years. The most recent addition has been vinyl sheets and these, with impervious sealants, have made this an attractive technology for the cutoff or containment of contaminated groundwater in this environmentally conscious age.
The lateral load against sheet piles can be increased with the use of whalers and struts or tieback anchors all of which Spiral Drillers Civil can advise you on. Some of the common uses of sheet piles are:
- retaining structures – temporary or permanent
- road stabilization
- vertical seepage barriers
- levees and dams
- trench support
- shafts and pits
