Abstract
A surface waterstop is in the form of a strip of rubber or plastics material. At least one keying formation, preferably a T-shaped formation, is provided on each side of a center line of the strip. A longitudinally-extending central section may be provided for receiving and locating stop-end shuttering. Along at least one lateral edge, and preferably along both lateral edges, the strip is adapted, for example by the provision of holes, slots or the like, to receive fixing pins or clips which, in use, extend at an acute angle to the surface on which the waterstop is laid.
