DryCrete Hydraulic WaterStop • Concrete Water Tank • D.I.Y. Repair Kit.


Surface Preparation
To repair concrete water tanks surface, they must be free from grease, oil, efflorescence and other surface contaminants.
Take care NOT to polish the surface such as with a wire wheel.
You can use a scraper or a chipping hammer, angle grinder/jackhammer or pressure cleaner. With a grinder/jackhammer, remember, you are not trying to cut concrete, just bullying the contaminants off the surface. Structure to be repaired and must have the basic structural integrity. Wet down thoroughly the surface to be coated immediately prior to application.


Temperature
For easiest results, apply when temperature is between 15C to 24C.

Mixing
Mix only the amount that can be used in a very short space of time. Mix with a small amount of water. The ratio should be about 4:1/2 parts powder to 1 part water. This can vary widely with your conditions & situation, so always mix a small test batch first.

Application
Apply putty ( The Putty Will Heat Up ) into the void/crack and hold, pressing the putty well in, and applying pressure. Dont be alarmed if a little washes off.


Where to Apply DryCrete Hydraulic WaterStop
Concrete Water Tank Repair

DryCrete Hydraulic WaterStop can be applied over or adjacent to cracks, suspected weak points, cold joints, porous surfaces, around fittings and can be applied to either side of the face of the concrete.

DryCrete Hydraulic WaterStop migrates through the voids in the concrete and will migrate up to 400mm from the point of application. The raw product itself is not waterproof ( in fact, it is highly water absorptive by design ).

When applying DryCrete Hydraulic WaterStop where there is flowing water, remember not to be too concerned that some product may wash off. It is important to focus on the intact material ( that hasnt washed off ) to ensure that it is correctly applied, cured and stimulated. Allow some time, then apply some more if needed.

Tip ....
If water is running down a vertical crack and washing the material off. Find the exact point of the leak and apply a blow with an hammer/chisel. This will compress material into the leak and temporarily reduce the flow during application. Even a sideways ( 45deg. ) scratch will take the water to one side.

Curing
Protect the surface from rain or frost during initial cure. ( Aprox 5 hours )








DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kits


Hydraulic WaterStop crystalline growth systems are proven on concrete mega structures world wide and are now available as a D.I.Y. kit.

DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kit helps waterproof your tank in compliance with AS 3735 Concrete Structures for retaining liquids.

DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kits are easy to use and offers superior and ongoing results as it continues to repair, seal and protect your concrete structure.

Your concrete structures can easily last a lifetime with little maintenance. DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kit helps you achieve this.

DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kits are sold across Australia & New Zealand. It comes packaged in 1kg/4kg containers, and will fix approximately ( 1kg = Aprox 2 linear meters of crack repair ).

DryCrete Hydraulic WaterStop - Concrete Water Tank - D.I.Y. Repair Kits continually repair cracks in concrete tanks up to .5mm as they continue to move within normal structural limits.

As the structure continues to move from ground movement, temperature fluctuation and load fluctuation the crystals regenerate, grow and repair the crack.

They can continue to do this for the life cycle of the structure.

Whilst we can quantify exactly how this product will perform, your results may depend on some other factors beyond our control such as:

• The Age of the Water Tank/Foundations and soil conditions
• Tank location eg. sun/shade/trees
• Original cement content thats is left & placement methods
• Reinforcement content, location and degradation
• Your preparation and application techniques


This product is well proven as the easiest and most cost effective way of making your concrete structures are fit for purpose. Incidental cracking small water loss from time to time is a normal part of concrete structures for the retention of liquids (AS3735).
