What is polyconcrete?
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.”
