Sewper® Liner
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 demonstrating a low environmental impact in its production phase compared to its economic value. Pioneer is our highest sustainability rating denoting products and services with an outstanding sustainability performance compared to the reference on the market.

As urbanization in India accelerates, so does the country’s construction sector and demand for locally-produced, sustainable construction practices suited to the subcontinent. Inaugurated one year ago, Imerys’ state-of-the-art calcium aluminate plant in Vizag, Andhra Pradesh, in India’s southeastern coastal region, produces new products that answer this precise need. It recently showcased its products and initiatives during a construction workshop for customers on October 16 in Mumbai.
While a building’s structure might make it a house, a building’s insulation will make it a home. And, while a builder might have many insulation options to choose from, only one can claim to be totally safe: mineral foams.
Achieving much more with less, or using less to achieve much more. That was the challenge Imerys experts set themselves in designing the next generation of specialty binders, designed for a market calling for greater performance with less product and lower environmental impact.
From energy usage to emissions and natural resources, the construction industry has a huge impact on the environment. Today, this impact translates to revisions in building regulations, leveraging of technological advances and new materials, and greater adoption of sustainable construction methods. This sustainability is what we strive for.
