SewperCoat® is a ready-to-use dry mortar specially designed for protecting sewage system infrastructure which is exposed to biogenic acid corrosion.
Whether for carrying out repairs on corroded structures or to protect new structures prior to their installation, the exceptional resistance of SewperCoat® to biogenic corrosion makes it possible to offer durable protection to infrastructure which is subject to the most demanding operating conditions.
SewperCoat® is also noted for its high mechanical resistance achieved even when it is still very new and an excellent resistance to abrasion which are combined to offer, in a single product, resistance to wear and corrosion as well as monitoring of leakage (in or out) and the reinforcement of aged structures.
Although SewperCoat® is a cement product, its 100% calcium aluminate content creates a “total barrier to reactions” which inhibits the activity of bacteria such as Thiobacillus which are responsible for sulphuric acid (H2SO4) build-up. The key to this exceptional stability resides in the fact that the binder and the aggregates are both composed of calcium aluminate and thus create a “seamless” surface protection. Furthermore, the perfect chemical and mineral affinity between the binder and the aggregates leads to the formation of an excellent chemical and mechanical binder when the product is hydrated, which also explains the excellent stability in thin-layer application.
SewperCoat® is used for protecting all sewage infrastructure: drainage, pumping stations, large collector ducts and other concrete infrastructure in wastewater treatment plants.
SewperCoat® may be applied by various procedures: low-pressure wet spraying, high-pressure dry spraying, or rotating distribution head.
SewperCoat® is manufactured in a quality management system environment, certified according to ISO 9001 standards.
