Donplast® W55
Integral waterproofing concrete admixture
Donplast W55 is a liquid concrete admixture formulated from selected organic materials specially designed to produce hydrophobic properties when mixed with concrete.
These hydrophobic materials will repel external water and reduce the permeability of concrete.
- Produces more durable concrete, lower in permeability.
- Provides concrete protection throughout the concrete depth.
- Chloride and bitumen-free.
- Tunnels, subways and manholes.
- Water retaining structures.
- Underground concrete constructions.
- Parking structures.
- Concrete floors.
Donplast W55 is available in 5 gal (19 litre) containers as well as 275 gal (1,041 litre) IBC totes. Bulk supply in tanker trucks is also available upon request.
Donplast W55 has a shelf life of 12 months from date of manufacture if stored at temperatures between 35˚F and 122˚F (2°C and 50°C).
The recommended dosage of Donplast W55 is 4 to 10 fl oz/100 Ib (260 - 650 ml/100 kg) of cement or cementitious materials in the mix including GGBFS, PFA or micro-silica.
Representative trials should first be conducted to determine the optimum dosage of Donplast W55 to meet the performance requirements by using the materials and conditions in actual use.
Donplast W55 complies with the requirements of Specification for Chemical Admixture for Concrete ASTM C494 as a Type A admixture.
