MAS magnesite kit

The chlorides in magnesite toppings can penetrate to the underlying floor reinforcement which then corrodes causing concrete spalling and delamination. Conventional repairs can be expensive and unreliable as it is difficult to remove all the chlorides.

We have developed two low cost effective electro-chemical systems: one is to bond zinc sheet with Zinc Activator Paste (ZAP) to the concrete surface, the other is to apply Zinc Layer Anode (ZLA) to the soffit. With a connection to the reinforcement either system provides galvanic cathodic protection to the reinforcement to ensure corrosion is halted with minimal concrete and topping removal.
