Arcon supply a range of products designed for use on building and engineering structures in the water industry that carry WRAS approval. WRAS stands for Water Regulations Advisory Scheme. Approvals can be given to products and materials that come into contact with the public mains water supply in the UK, to ensure that they comply with Water Supply (Water Fittings) Regulations or Scottish Byelaws.
WRAS approved sealants for sealing movement joints in structures such as potable water tanks, reservoirs, retaining structures, dams, culverts, waste water treatment plants etc. include: Nitoseal MS600 with MS2 Primer.
WRAS approved materials for coating concrete and steel include Nitocote EP405 a high build-epoxy resin coating and cementitious waterproof coatings, such as Nitocote CM210, for water retaining and water excluding structures. Sikagard-62 is also suitable for contact with potable water (DWI Ref Number 56.4.197). Brushbond FLXII is a WRAS approved elastomeric waterproofing coating.
Sikadur-31DW and Sikadur-31DW Rapid are thixotropic epoxy resin adhesives and repair mortars designed for use in contact with drinking water.

It has been used in water supply reservoirs, culverts, tunnels, tanks, pipes, waste water treatment plants and hydro-electric power plants to name just a few applications.
Water stops and water bars are used in in situ concrete structures to prevent water leaking through construction joints and junctions. WRAS approved rigid waterstops include Supercast PVC Waterstop Hydrofoil. WRAS approved hydrophilic swellable water bars include Supercast SW10, Supercast SW20 and Supercast SW30
Biolease Standard a biodegradable mould release agent containing vegetable oils emulsified in water for use with all types of formwork to give a high quality finish.
