NCC Waterworks, Kristianstad

Centrala Reningsverket, the central treatment plant of Kristianstad kommun, runs permanently wet concrete basins under constant chemical and biological load — the substrate stays damp, so any lining has to bond to it wet and stay vapour-permeable afterwards.

Eco All In One was applied as the basin lining and combined with Eco Sil. Both are mineral, spray-applied and cure into the concrete rather than sitting on it as a film.

A pull-off adhesion test taken on site read 2.679 N/mm² — measured on the plant's own substrate, not in a laboratory.
