Ruberoid Hyload Housebuilder is used for damp proofing stone, concrete and brick walls. It can be used for both solid and cavity walls. It can also be used as a cavity tray. This product is particularly suitable for the domestic house builder (hence the name) because of how cost effective it is. It can be used in buildings up to three storeys high. It is superior to traditional DPCs because it will not become brittle or tough in temperatures below freezing. It remains supple and workable and always easy to cut.
