Yes, but only providing the area to be treated is totally dry upon application to allow capillary absorption and then necessary waterings to take place on the negative side prior to water moving back from the positive side. This is generally why crystal growth are preferred negative pressure side applications, as crystals will migrate against the positive side water pressure.

Crystal growths offer sulphate resistance as the active ingredients utilise dissolvable calcium to form dentridic crystals making the concrete more stable to attack but not totally resistant over the long term.
Radcon also offers greater sulphate protection by utilising free calcium to form its glass hard gel.
As neither crystal growths nor Radcon can offer total long term protection in these applications Radcon has not been tested to show its level of improved performance.

he Radcon bond wrench test shows a 27% plus bond increase between cementitious materials. (Columbia University – Tensile strength test)

The listed materials are unable to penetrate into Radcon Formula # 7® treated concrete.

For example, grease will always leave a permanent stain on untreated concrete. Radcon treated concrete cannot be permanently stained with grease, the concrete will clean up as the grease and other materials listed will lack penetration which would create permanent discolouration to the effected areas.

Furthermore these materials cannot adversely effect the Radcon product performance. Therefore Radcon product performance will be fully maintained.

No, Radcon is a breathing system which allows for moisture vapour outgassing whilst preventing both the ingress of water molecules and pollutants from reaching any steel reinforcement.

Radcon will waterproof all cementitious concretes for the life of the structure.

Premature Radcon failures will occur if Radcon waterproofing is applied to pozzolanic concrete mix designs.

The other tangible benefits utilising Radcon can be both significant and varied.
a)Low cost application – Radcon can be applied very fast when compared to traditional membrane detailing work.
b)Fast Track Construction – Often in wet climates the need to have all moisture removed from the concrete prior to placing a non-breathing material over the top can add significant time delays. By comparison Radcon can be applied as soon as the concrete surface is visually dry.

Yes! But quite often the "form release agents" used by the pre-cast manufacturers may be of a wax or oil base. Before treating pre-cast elements with Radcon waterproofing one must ensure no residual form release agent is present as this would repel Radcon penetration. Furthermore any residual release agent may cause "white stains" in patchy areas. If in doubt a trial application prior to a fully committed application may be an appropriate first step.

Let us dwell on certified materials. A product which prevents both water and salt ingress into the concrete matrix and cracks present thus meeting Clause 4.3.1© of AS3600Code with regard to chloride and water permeability.
On this basis Radcon represents the lowest cost concrete waterproofing approach available in the global marketplace.

It is the highly alkali nature of cementitious concretes which delivers passivity to the steel preventing rust. Again the high pH of Radcon acts in exactly the same protective way.
In fact “University of New South Wales tests” confirm Radcon in itself can reinstate alkalinity into Alkali depleted concretes.
