About us Vardy Mining & Waterproofing was established in 2009. After 7 years of intense research and development of Nu. ROCK, with our focus on the mining industry. Nu. ROCK has been specifically manufactured to enhance safety, prevention of rock falls in mines. From Nu. Rock the Nu. Seal Waterproofing product was developed due to popular demand for a good quality, long lasting, easy application and economical waterproofing product. v. Rock support underground v Gold Mines, Platinum, Chrome, Coal, Iron Ore

PORTFOLIO Nu. SEAL WATERPROOF & Damp seal; Nu. SEAL was developed as a one pack application coating which is membrane structured and is completely water resistant and non toxic when dry. The product carries strength of 3 MPA bonding on cement and is UV resistant. Because of its composition it is hard wearing and has excellent weather capabilities. It remains flexible and can be used on most substrates e. g. Steel, concrete, expansion joints, sealing of dams, Stainless Steel, Wood, Floors, Walls, and cement Ceilings and has excellent resistance to acid and alkaline Nu. Sea. L is easily applied by compressed air at 6 bar pressure. A 0. 5 to 2 mm thickness as waterproofing or rubber coating. It can be sprayed into the smallest cracks, corners and can also be brushed on small areas. Easily repaired by just brushing over or just spraying over damaged or warn areas but no need to remove damaged Nu. Sea. L seal: Roofs, Slabs, Dams (Sink, Concrete), Basements, Man Holes, Sewerage Dams, Ponds, Building Maintenance and Construction. Insulation: Nu. Seal has a very good insulation property. On a 26°C day the temperature on a sink roof was 44°C but on the roof that had Nu. Seal applied, the temperature was only 22°C. A reduction of 50%. , Nu. Sea. L has NO JOINTS, therefore water can run easily to the draining points. Nu. Roc. K For underground Rock support and Safety 0. 5 to 2. 5 mm thick application layer Up to a 5 mpa bonding strength Up to a 13 mpa tensile strength Can spray close on face Fire retardant 100% UV resistant Reduces oxidation Non toxic Environmentally friendly 5 -200% elastic Maintenance - none Up to 400 m² per day application rate Nu. DUST Dust reduction, roads, conveyers, crushers, dump bins Up to 5 days dust control on roads Cost effective Fuel saving Reduces maintenance costs Nu. RUSTCON is a single pack product that is easily applied by brush, roller or dipping. It converts unstable iron oxide to iron phosphate, thus providing a sound substrate for factory maintenance purposes especially where blast cleaning and other methods of surface preparation are impracticable. On “Pitted” steelwork even if re brushed you will still leave rust behind but an application of Rustcon will transform the rust to iron Phosphate thus alleviating the problem that the rust creeps.

Application Process Nu. Roc. K and Nu. Sea. L is applied with air @ 6 bar pressure. The work surface is cleaned by just blowing it with air or washed with high pressure washer, followed by an application of primer which will absorb any small particles of dust. Primer is also the bonding agent on the different surfaces and requires approximately 15 -20 minutes drying time - only if required. Nu. Sea. L / Nu. Rea. K Nu. Dus. T standard application of 1 -3 layers depending of surface may require a 2 to 2. 5 mm thickness i. e. Mining Sector. is added into a tanker and sprayed on road surface Primer Primary Layer Finished Product Kindly note that water is required on site for cleaning equipment during and after application.
