Consultants for Construction Innovation (C4Ci) is working with materials supplier Lime Technology to develop its Tradical Hemcrete product. <br> <br> Tradical Hemcrete is a bio-composite material comprising hemp fibre mixed with a lime binder. Water is added to the mixture and the resulting material is packed into timber formwork where it cures and forms an airtight insulation layer. <br> <br> C4Ci md Luke Whale explains: “Tradical Hemcrete is an on-site product which is great for the self-builder. Our challenge is to bring Hemcrete to the volume of timber frame manufacture and we are making strides.” <br> <br> C4Ci is helping Lime Technology design a permanent formwork system using existing timber frame technology. The Tradical Hemcrete mixture is poured into the formwork, supported by lightweight timber studwork, and cures to create a “breathable” composite panel. <br> <br> Visit www.c4ci.eu or enter E0705 on the reader enquiry card
