WaterProofing System

Radcon and Radmyx provides non-toxic waterproofing systems and its durability where no re-application or future maintenance is required! It is safe, convenient and efficient, with no protection required.


Radcon formula #7


Radcon Formula #7 is a biochemically modified silicate solution that provides long-term waterproofing and durability benefits to concrete. It penetrates into concrete and reacts with free calcium and water to form a non-water soluble calcium silicate hydrate gel complex in cracks, pores and capillaries. This gel creates a sub-surface barrier against the ingress of water and contaminants such as chloride ions.

Radcon Formula #7 will seal existing leaking cracks up to 2.00mm. In the matrix the product remains reactive when in contact with water to provide autogenous healing properties to future hairline cracks.

The unique features of Radon Formula #7 relate to it’s silicate composition which has been biochemically modified. Firstly, the product will permanently waterproof existing leaking cracks in concrete up to 2.00mm, even when exposed to typical high thermal stresses on rooftops. Secondly, the product that has absorbed into the concrete matrix remains active to seal new hairline cracks on contact with water. This phenomemom has been confirmed on applications in areas of earthquake actitivty,

The application rate with one motorised spray unit ranges up to 800 sqm per hour. This enables relatively quick product application to fast-track projects.


Ease of Application

Although the product requires a level of technical competence, it is easy to apply. At the end of the application this can easily be tested by ponding the treated area.


Trafficable (After 1st Watering)

After the first watering is completed, at approximately 6 hours after product application, the site becomes completely trafficable. This increases site time efficiency and reduces risk of damage from other trades during construction.



In humid environments trapped moisture in concrete often leads to premature delamination of membranes. Alternatively, Radcon Formula #7 still enables the concrete to out-gas moisture eliminating this problem.

In freeze/thaw environments, Radcon Formula #7 significantly reduces moisture absorption into the matrix and seals cracks increasing the concrete’s durability in this harsh environment. The out-gassing also allows moisture to evaporate out of the concrete reducing freeze-thaw damage.


Radcon Formula #7 is water-based. Equipment can easily be cleaned and the product can be safely handled on-site.


Complete Waterproofing

Radcon Formula #7 is a complete replacement for a membrane as it is waterproofs both the concrete matrix, and cracks even when exposed to high thermal stresses. The penetrated product remains reactive in the presence of water to provide autogenous healing capabilities to future hairline cracking.


Risk Management

Radcon Formula #7 is applied directly to structural concrete with no requirement for a protective screed – one waterproofing variable. Thus, if, at any stage of the building’s life, a leakage occurs it can be repaired quickly and easily with no tracking beneath a membrane or screed. This approach drastically reduces the cost of ongoing maintenance with no removal of membranes or toppings.


Proven Performance

With product applications dating back to 1975, Radcon Formula #7 has developed an enviable track record, based on successful long term performance. Radcon Formula #7 is available across some 25+ countries and now waterproofing sites of global recognition.
