New kid on the block: Sewper® Liner

Sewper® Liner is our latest product innovation based on calcium aluminate that provides new-build wastewater infrastructures highest durability by protecting them from most severe H2S biogenic corrosion. 

Today, when H2S biogenic corrosion is expected, new wastewater concrete infrastructures are typically sprayed with polymer liners - like epoxy - as a form of protection, but its lack of durability means it fails too often after only a few years. Starting from the same technology as for our highly successful SewperCoat® solutions, we developed Sewper® Liner, a radically innovative formulation to achieve long-lasting protection on the dry, flat and smooth walls of new concrete assets.

Sewper® Liner is three to five times thinner than SewperCoat®, making it ideal for larger surfaces so it can be sprayed quicker speeding up the construction process which in turn keeps the costs down. All that without compromising long term H2S corrosion resistance and durability associated to calcium aluminate technology.

Sewper Liner: an Imerys Pioneer product

As a reliable protective coating solution which provides a longer service life to wastewater assets compared to high turnover epoxy resin, Sewper Liner is a certified Imerys Pioneer product. This means it provides the highest environmental contribution to the downstream value chain, whilst also demonstrating a low environmental impact in its production phase compared to its economic value. Pioneer product status is our highest rating for products and services with an outstanding sustainability performance compared to the reference on the market.
