With durability being a necessity in today’s construction industry, it is no wonder people are shifting to practices and products that better the strength of the structure and more importantly it’s most essential part; concrete. As opposed to external protection or strengthening, having concrete that protects itself and can resist environmental attacks (such as sulphate, chloride, alkali) are the way forward. For concrete, the best and most efficient method in ensuring this is to create sustainable structures by using the most durable concrete possibly. In most cases, the reason behind concrete deterioration is the ingress of water. Water breaks into the concrete moisture through cracks and pores, infiltrating the matrix and effectively limiting the durability of the structure. When concrete durability is compromised, the sustainability and resilience of the structure is also compromised.

Methods to protect concrete from water are many. Setting up surface applied or external barriers, for the concrete is the traditional, most widely accepted and used methodolgy with which water is blocked from entering concrete, which, by nature is porous. However, there are inherent risks to a construction project in using this method. Traditional surface applied membranes can be unreliable and easily punctured during a time consuming and costly installation process. Not to mention the fact that a puncture in an externally applied membrane can be impossible to fix, leaving the viability of a project vulnerable.

The right solution must be to protect from inside, and that’s where crystalline system works. A true crystalline system will decrease permeability of the concrete adding years to the structure while saving on time and eliminating all the problems faced while setting an external barrier system such as membranes etc. Crystalline system is a reactive technology and it makes concrete structure self-resistant to water without any coating or membrane. Crystalline is also, the only system which is applicable from the negative side and works under a high water pressure of head resistance up to 160m.

Working with crystalline is easy, convenient and the product is performance oriented.  You save on time and money which doesn’t just add technical but also monetary value to the building. The add on is that crystalline waterproofing material also fills cracks of 0.5mm, which generally develop due to temperature fluctuation and heat of hydration.

In fact, more and more specifiers and builders are putting their trust in crystalline to make their concrete more durable and add protection from within. These products are available for both new and old structures and can be applied in the form of admixtures or surface applied systems.
