Solvent-free epoxy-based systems for the waterproofing and protection of concrete and steel works
against premature degradation due to the corrosive nature of the gases emitted by domestic
and industrial waste waters, notably H2S.
Resistance to permanent or temporary contact with industrial effluents and sea water.

Our BIOPERL range is designed for the waterproofing and protection of both the interior
and the exterior components of wastewater treatment plants and of seawater desalination plants
(digesters, clarifiers, settling tanks, filters, thickeners, flocculation tanks, storage tanks, manholes,
pits, gutters, channels, catch basins, …) as well as of the interior of large-diameter pipes, in new-build
and rehabilitation projects.

Simple and quick to clean thanks to their smooth and homogeneous finishing.

Comply with all sanitary and toxicological regulations in force.
Their chemical formulation makes it possible to withstand gases (H2S, methane) and aggressive liquids
(seawater, brackish water, industrial water), thus significantly increasing the useful life of protected structures
and their performance (digesters for example).

Epoxy resin / glass fabric multi-layer lamination gives the system resistance to existing
and future cracking in a concrete substrate of up to 20/10ths of a millimeter.
