<p>Water-activatible tapes are disclosed comprising a fibrous or foamed plastics material impregnated with a cement composition and preferably containing a natural or synthetic rubber binder. The tapes are suitable for construction or sealing purposes, e.g. sealing joints in building structures or pipe-wrapping, by wetting with water to form a pliable mass which can be deformed to the desired shape and which will subsequently harden.</p> |
