Acothane Wasteseal
Acothane Wasteseal (formally named Corroless ACO Wasteseal) is a sprayable structural composite lining for new pipes and the restoration of existing pipes. The technology has more than 40 years of field use in pipe lining and external pipeline protection.
Acothane Wasteseal is formulated as a carbon fibre reinforced, solvent free, hybrid polyurethane coating to provide the stability you require. By incorporating carbon fibre reinforcement, the coating is designed to deliver maximum strength and durability. For restoration cases, Acothane Wasteseal is designed to remain intact even after the original pipe has decayed away.
Key benefits

VOC free
-
Excellent strength, stiffness and durability
-
No timely and costly earth work
-
Minimal invasive reinforcement
-
Customized applications
-
Fast back to service , 1 hour
-

-
Feathers into outlets as it is applied à No cutting out of pipe joints required
-
Low wear rate in abrasive flows
-
No shrinkage
-
Lining lengths of up to 1km per week achievable
Application
Acothane Wasteseal is applied using a centrifugal process. The coating feathers into outlets as it is applied so cutting out joints is not required.
Suitable for iron, cement mortar lined, clay and steel pipes from 75mm to 2000mm. A continuous spray yields a leak free, corrosion resistant, seamless lining for up to 430m lengths in a single operation.
Acothane Wasteseal is a rapid ambient curing, thermos chemical coating, it requires no steam, hot water recirculation or UV to achieve a full cure, which creates an environment that facilitates quick repairs and reduced down times.
