Waterproofing Admixture Help In Minimizing The Permeability Of Concrete By Creating A Water Resistant Layer And Also Enhance The Ability To Withstand Moisture

 

Waterproofing Admixture

Waterproofing Admixture is a type of admixture used to improve the water-resistance of concrete structures. The admixture can be added to the cement mix during mixing to enhance the resistance to water penetration and to reduce the likelihood of damage by rainwater, groundwater or other sources of water.

There are a number of different types of Waterproofing Admixture available that claim to improve the durability of concrete. They offer attractive claims, technical back-up warranties and, in many cases, can be a critical component of the design of a concrete structure that is exposed to water.

Crystalline waterproofing admixtures react with unhydrated cement particles and form crystals that fill capillary pores and micro-cracks and block the pathways for water penetration. They also help to reduce corrosion and add longevity to reinforced concrete.

These crystalline Waterproofing Admixture are typically offered in pourable liquid form, as well as powders that can be mixed on site or at the plant. They can be sized to fit five-pound bags or 50-pound sacks for use in the mixer, or can be stored in six-gallon pails or 250-gallon totes on the jobsite.

The effectiveness of crystalline Waterproofing Admixture depends on a number of factors, including the amount of water in the concrete and the temperature at which it is poured. Crystalline admixtures are most effective when they are applied at temperatures below 70 degrees F and below 25 degrees C.

They can be used on new or old concrete, in both interior and exterior applications. They can be applied in a range of methods, including spray-applied, roll-applied and trowel-applied.

The use of a robust, waterproof tanking membrane can be particularly important in the case of water treatment plants and other facilities that are subjected to harsh chemical environments. The admixture manufacturer may offer a warranty on labor and material for a set number of years.

Waterproofing Admixture commonly include anti-shrinkage additives that reduce the shrinkage of concrete and pore-blocking materials that are designed to seal small, porous areas in concrete such as voids or micro-cracks. These admixtures are also available for shotcrete and can be used in combination with other types of crystalline waterproofing admixtures to achieve the most comprehensive, long-term waterproofing system possible.
