What is poly­con­crete?

Home (South Africa) - - GARDEN FURNITURE -

Light­weight con­crete-like prod­ucts such as resin-based poly­con­crete boast a mix­ture of poly­mer resin and a num­ber of fillers that range from coarse sand to fine pow­ders re­in­forced with glass fi­bre strands, ex­plains Britt Youens from Ig­neous which spe­cialises in this type of fur­ni­ture, pots and planters. “This mix varies ac­cord­ing to the weight and com­plex­ity of the mould­ings and can be pig­mented to any colour. Once moulded, the prod­uct is then cov­ered with a polyester top­coat that is pig­ment-matched to the core ma­te­rial.”

Each item in the resin-based poly­con­crete range is ap­prox­i­mately half the weight of a com­pa­ra­ble piece made from tra­di­tional ce­men­ti­tious con­crete,” says Britt. “Items made from glass fi­bre re­in­forced poly­con­crete are be­tween two-thirds and three-quar­ters lighter than tra­di­tional ce­men­ti­tious con­crete. This has sig­nif­i­cant im­pli­ca­tions for ap­pli­ca­tion where there are load-bear­ing struc­tures. That said, the items are still weighty and are, there­fore, also highly tol­er­ant of strong winds.”
