Timber piles often require rehabilitation and a more recent method of rehabilitation includes the use of a Fibre Reinforced Polymer (FRP) encasement which essentially confines the deteriorated or damaged pile. A suitable filler material is required to infill the area between the FRP and timber pile and is required to transfer all vertical and lateral loads through axial compression and bending.

This paper presents the mechanical properties and behaviours of both epoxy and vinylester polymer concrete as a filler material. Different proportions of polymer resin and fly ash were mixed with 57% sand by volume and tested
under an extensive experimental testing program. At current there is no literature evident of a polymer concrete mix design of polymer resin, fly ash and sand. The results from testing were analysed and then used to determine a trend of mechanical properties and behaviours of the two concrete types.

Compression tests were undertaken at 7, 21 and 28 days to determine the compressive strength gain over a period of time. The compression tests at 7 days involved a stress-strain analysis using the platen to platen method.
Split tensile and three point bending flexural tests were undertaken at 7 days to determine split tensile strength and flexural modulus respectively.
