Nexseal Waterproofing Admixture is a next generation, crystalline, waterproofing admix. It has been designed to waterproof and improve the durability of concrete using hydrophilic, hydration enhancing, crystalline technology. Nexseal Waterproofing Admixture is added to fresh concrete easily at the batch plant or directly into ready mix trucks. It works to continuously prevent moisture from penetrating through the Concrete by creating a catalytic reaction within the pores and capillaries to enhance the hydration process of the cement component within the concrete. The enhanced hydration process not only provides waterproofing characteristics to the concrete, it also allows for an increased ability to self-heal micro cracking upon the presence of moisture.
Recommended for
- Swimming pools
- Tunnels and subway systems
- Parking garages
- All below grade concrete foundations
- Rooftops
- Dry vaults
- Sewage and water treatment plants
- Water towers and water reservoirs
- Marine structures
- Pipes
- Bridge decks
- Concrete walls and floor
APPLICATION
Nexseal Waterproofing Admixture is a dry powder that is added directly to the concrete during mixing. The dosage rate is 1 kg per m3 of concrete (see Dosage). Reduce the water component by 2 to 5% to achieve equal slumps on most mix designs (subject to mix design and raw material components). Even though the concrete will look less wet than most concrete mixes, it will provide an increased workability resulting in increased productivity.
Advantages
As a one time only application for the life of the concrete, Nexseal Waterproofing Admixture is user friendly and easy to apply.
- Will reduce shrinkage cracks by up to 60%
- Will reduce water demand by up to 5%
- Will eliminate the use of a waterproofing sub-trade
- Will continually improve impermeability benefits with time
· Will protect against water penetration through micro-cracks by autogenously healing future micro-cracking
· Will reactivate the waterproofing mechanism should water be present in the future
- Will increase the durability of the concrete
- Will protect against cracking and spalling
- Will stop water penetration into the concrete
- Will eliminate the need for any other waterproofing system
