Dump mixes rely on their vast specific surface area for their bond strength and rheological properties. This also results in several other significant properties; Good thermal shock resistance Very strong capillary suction. High surface tension, which makes them stick to buckets rather than falling out. They are not sucked dry by conventional materials if cast against them. Hydraulic bonded materials cast up against them are sucked dry. Therefore Dump mixes cannot be used to repair dump mixes. Interrupted castings will not bond at the joints.

A viscous phosphate bonded mix, Phospatch can be used to repair dump mixes. It is very fast setting and will bond to almost any surface. It can even bond to a surface vertically above it. It has been used to repair the inside of arc furnace roofs by pouring through electrode holes into shuttering under the roof.
