Generally all crystalline products, including Radmyx, cause some retardation of the set. For this reason we recommend that consideration be given to the use of an accelerator when using Radmyx.  Radmyx used with an accelerator complies with AS 1478.

Radmyx causes an increase in compressive strength of the concrete.  CSIRO testing in Australia showed that Radmyx caused an increase in compressive strength of between 15% and 20%.   The temperature of the concrete is not affected.

Radmyx is best added to the dry mix at the time of batching, however, it can be added to the mixer on site.  When added directly to the concrete truck it is essential to rotate the mix for ten minutes prior to pouring.

The general dosage as an admixture is 0.78kg per cubic metre of concrete.   Under special circumstances it may be necessary to vary this amount according to site conditions or design mix requirements. 

The crystalline growth technology of Radmyx provides many advantages over traditional membranes:

Radmyx, through its unique crystalline growth technology, can be used as an admixture (added at the time of concrete batching), as a coating (for new or existing structures), or as a dry shake mixture (for fresh horizontal surfaces).  

The environmentally sustainable crystal growth technology of Radmyx brings significant efficiencies and differences to the capability of concrete waterproofing.  This technology ensures Radmyx has greater capability than traditional membranes and cementitious coatings.

Radmyx is traditionally used on below grade structures such as basements as well as reservoirs, tunnels, foundations, underground vaults, water tanks, sewage and water treatment tanks, car parks, swimming pools and foundations.  It is also suitable for use on pre-stressed decks. 

Yes.  Radmyx is an excellent remedial waterproofing agent.  Radmyx’s crystalline growth will operate as a specific repair system to stop the ingress of water through most cracks and other defects to ensure a complete waterproof seal.  However, Radmyx is not suitable for waterproofing dynamic cracks or movement joints. An elastomeric joint sealant will need to be used for these conditions.  

Radmyx is suitable for all types of concrete surfaces including poured in place, pre-cast, or block concrete. It is not suitable for non-concrete building materials.
