to a failure of the waterproof membrane, the stainless steel links would guarantee a
ductile failure mode.
Conventional carbon steel may be coated with epoxy resin to protect it from
corrosion. This was popular some years ago, but is falling out of favour. There are
reports that the adhesion of concrete to such coated steel may be reduced, with

delivery and installation.
Much research has been carried out on reinforcement consisting of fi breglass rods.
Conventional glass is attacked by the alkali in the cement, but special alkali-resistant
