Powder crystallizer penetrator

Powder crystallizer penetrator

CRYSTAK is a powder crystallizer penetrator that can crystalize inside concrete capillary pipes, thus making them resistant to the penetration of water and a wide range of chemicals. This product provides the most effective method of sealing and chemical and permanent protection of concrete, which only needs to be mixed with water for consumption.


“CRYSTAK as a penetrating powder crystallizing product has the following applications: ” Sealing elevator shafts Insulation of ponds and water features Sealing tunnels, dams and water reservoirs Sealing pools and sewage septics Fix leakage of executive seams and cold seams Sealing tunnels, piers and water transfer canals Repairing structures with dampness and permeability Sealing and insulation of water and wastewater treatment plants


facility in operation self-repairing ability of cracks resistant aginst alkaline and acidic materials Protect concrete and reinforcement against corrosion Impermeability and sealing in the used sections Resistance to the invasion of chemical agents and corrosive salts Ability to seal and make the sections impermeable High penetration into the concrete and formation of a uniform texture with it Occlusion of capillary holes and cracks due to shrinkage


This product is supplied in 25 kg bags.

Typical properties

physical state powder color grey density ۱.۸ – ۲.۰ kg/L * The mentioned data are obtained based on the latest controlled laboratory tests.


This product can be evaluated according to the following standard: CRD-C48-92

application guidline

The mixing water ratio required for this product is 10 kg per 25 kg bag. It is better to complete the entire surface repair operation within 30 minutes after adding water to the mixture. Consumption amount of this material, depending on the porosity and permeability of the substrate, is about 800 to 1200 grams per square meter. It is recommended to use this product at an ambient temperature of 10 to 35 degrees Celsius and the temperature of the mixture during the using should not exceed 30 degrees.


first pour required water in mixing bowl and then add the powder slowly. Turn on the mixing instrument and continue the mixing process with slow speed (lower than 500 round per minutes) for one minutes. Try to finish the process whithin 30 minutes. Cover the prepared cement surface with the prepared mortar with brush in two steps. In a way that, during operation after drying the first layer, apply the second layer. At least for three days spray the surface with water. All parts in contact with the repair mortar should be free of any dirt, grease, dust, etc. and it is better to moisten with a little water.
