Fibreglass FRP
Available for Purchase from NZ Stocks.
Fibreglass, Fibre reinforced polymer (FRP) are a medium to high strength sheet pile most suitable where corrosion resistance is required. Lighter & easier to handle than steel sheet piling. FRP offers an environmentally friendly alternative for use in marine structures, coastal protection & flood walls.

How cost effective are Fibreglass Sheet Piles when compared with Steel?
Fibreglass sheet piles will be cheaper in corrosive environments where steel needs to be coated or thicker to combat the effects of corrosion plus the interlocks/clutches of steel sheet piles cannot be coated. Another advantage of Fibreglass is, no on-going maintenance
How strong are the Fibreglass Sheet Piles when compared with Steel?
The longitudinal strength of Fibreglass is a lot less than steel due to steel being alot stiffer over its length.
However the other strength properties are often higher than a similar steel sheet pile. Eg: UC75 has similar & higher strength properties than SP3W. UC95 has similar or higher strength properties than SP4W
How are Fibreglass Sheet Piles driven?
Sheets are best driven using a guide frame for alignment. Depending on how hard the soil is, the sheets are normally driven with a crane or excavator mounted vibratory pile-driver with a ‘Piling Helmet’ which clips over the top of the pile.
In soils with large stones or solid objects near the surface, a trench can be dug, then the sheets can be installed as normal in the trench, then the trench backfilled
Can Fibreglass Sheet Piles be driven into Rock or Solid Objects?
No. The Fibreglass sheet pile will get damaged or break. Steel sheet pile will also be damaged if driven into these objects
How much does Fibreglass Sheet Pile weigh per metre?
UC75 is 610mm wide and 20kgs per lineal metre
UC95 is 762mm wide and 32 kgs per lineal metre
How hard can the ground conditions be to drive Fibreglass Sheet Pile into?
UC75 can be driven into soils with a SPT N reading of up to 40. Driving in soils harder will require pre-drilling with a CFA type auger OR using a mandrel to hold & drive the sheet pile. Mandrels can be very costly to build, the size of the project would determine if this is economic
UC95 can be driven without the need of a Mandrel or Pre-Drilling due to its strength
