DWI & WRAS
Clever Shield provide DWI and WRAS approved polyurea and cementitious waterproof coatings for water and wastewater assets including service reservoirs, water towers and water tanks.
Aside from their approved uses with water containment certified to DM 174 (water intended for human consumption) they can also be used for waterproofing and as a repair material for public, commercial and domestic water features, fish farms and ponds.
Polyurea
QuickSpray Supreme W and Industrial W Polyurea - Certified to DM 174 06/04/2004 - Regulation of materials and objects that can be used in treatment, supply and distribution of water intended for human consumption.
Supreme W is an instant curing, spray applied, seamless, and flexible protective membrane that exhibits excellent impact and tear strength. It will not crack, peel or splinter even under the harshest conditions and requires no maintenance to maintain ins integrity and physical features.
Supreme W is a specially formulated high performance lining designed for use in potable water applications. It`s unique formula guarantees the highest levels of water purity when used in human drinking water storage and transport vessels even at elevated temperatures.
Supreme W has potable water approvals from across the globe and meets the most stringent testing requirements.
Industrial W is a specially formulated cheaper alternative to QuickSpray Supreme W and is designed for use in potable water applications up to ambient temperatures.
Industrial W has various potable water approvals limited to applications between 23C and 40C.

Cementitious Waterproofing
HydraDry Tanking Slurry is a cementitious waterproofing system which creates a monolithic bond using crystalline chemicals when applied to concrete and masonry structures. When mixed with clean water and applied correctly, this forms a permanent waterproof coating to the substrate and is easily applied by brush, trowel or spray.
HydraDry Tanking Slurry waterproofs against both positive and negative hydrostatic heads of water, and is suitable for use internally, externally, above and below ground.
HydraDry Tanking Slurry is also ideal for use as part of a damp-proofing course (DPC).
NOTE: When applying HydraDry Tanking Slurry to a structure housing aquatic life, overcoating with Wykamol Technoseal DPM in line with the relevant data sheet is necessary, which is available upon request or can be downloaded from our website.
- BBA Approved
- Permanent waterproofing for concrete & masonry
- Resists positive and negative water pressure
- Superior bond strength due to crystalline technology
- Prevents migration of hygroscopic salts
- Suitable for use above & below ground
- Suitable for internal & external use
- Safe to use in contact with potable water (WRAS APPROVED)
Fish Farms and Pond Coatings
Aside from the above polyurea and cementitious coating products SilaCote ST polymer coatings can be used to seal ponds, fountains and water features.
SilaCote is a premium, liquid applied, permanent elastic, cold applied and cold curing, moisture triggered, silane, aliphatic membrane used for long-lasting waterproofing.
SilaCote Liquid silicone Waterproofing System is completely isocyanate free, single liquid component roofing system, containing no solvents, no volatile organic compounds (VOC's) and does not require classification or marking as a hazardous substance.
- Fully reinforced with an air mesh membrane when required and has a moisture trigger curing process.
- SilaCote is mostly independent from the weather it can be applied under almost any conditions, even on cold, damp days.
- SilaCote Polymer modified waterproofing membranes can bridge cracks caused by movement of the substrate. Liquid waterproofing membranes can be applied easily, even on damp substrates and dry very quickly.
- Silacote Systems comply with the BBA and European Technical Approval Guidelines (ETAG) for liquid applied roof waterproofing for all listed use categories.
