Nanotechnology based Elastomeric Hydrophobic Powder (EHP) compatible with cement concrete and is highly stretchable, durable and hydrophobic. It contains Nano-Ca (30-100 nm), Nano carbon (10 to 20 nm) and Nano Al- silicate (40-50 nm) The material is hydrophobic/waterproofing concrete/Plaster. It increases the strength of the concrete and will provide high thermal insulation. It is also corrosion resistance to the concrete/plaster. It reducing the curing by 20% depends on weathering condition.
