GRASi® WB100 is nano dry powder waterproof agent developed for concrete and cement. After mixing with construction aggregate, waterproof dry powder construction material or waterproof cement-based products can be obtained. Besides, excellent waterproof effect can be achieved completely from inside the substrate.
For use on cementitous substrates production process such as concrete, aerated concrete, mortar and other composite material that require water repellency. Such as bridge structures, harbor, parking decks, Highways and warehouse; protect the in-side and out-side wall, roof and floor of the buildings, underground engineering.

GRASi® WB100 nano powder is a kind of dry powder material, which is added into construction aggregate.
The best adding volume should be determined by laboratory evaluation.
The highest adding volume can reach the 2.5% ratio of construction aggregate weight. However, in most applications, WB100 nano powder added into aggregate, adding volume is 0.2%-2.5% of the weight ratio.
The final proportion of water should be determined according to the desired hardness of the formula.
