Radmyx\u2122 reacts with the hydration products of cement and creates an internal membrane in the form of insoluble crystals in the cracks, pores and capillaries of concrete \u2013 effectively blocking water penetration while allowing the structure to breathe.<\/p>\n\n\n\n

<\/figure>\n<\/div>\n<\/div>\n<\/div>\n\n\n\nIn contact with water, the crystals \u201cgrow\u201d, forming a waterproof layer that acts like a protective membrane to prevent water from penetrating the concrete. Each subsequent contact of Radmyx\u2122 particles with water stimulates crystallization again.<\/p>\n\n\n\n
Radmyx\u2122 is equally effective against positive and negative water pressure.<\/p>\n\n\n\n
Radmyx\u2122 can be used as:<\/p>\n\n\n\n
- \n
- additive<\/strong> which is added during the concrete mixing phase (in new construction).<\/li>\n\n\n\n
- coating or plaster<\/strong> which is used in the repair of old concrete.<\/li>\n\n\n\n
- dusting powder<\/strong> on fresh concrete in order to strengthen the concrete surface.<\/li>\n<\/ul>\n\n\n\n
Dosage<\/h2>\n\n\n\n
It is added to a dry or fresh concrete mix 0.78 kg of Radmyx\u2122 additive for 1 m\u00b3 of concrete<\/strong> . Since it is used as a concentrated admixture, it contains a much larger number of active particles within the concrete structure itself and therefore has a greater ability to continuously produce crystals in the future.<\/p>\n\n\n\n

<\/figure>\n<\/div>\n<\/div>\n\n\n\nKey advantages <\/h2>\n\n\n\n
- \n
- Concentrate<\/strong>\u2013 since Radmyx\u2122 is added to concrete as a concentrate, its \u201cactive ingredient\u201d is not diluted with sand and cement, unlike other crystal products, and its ability to continue to produce crystals in the future will be superior compared to other crystal growth-based products.<\/li>\n\n\n\n
- Easy<\/strong> \u2013 since a small amount is required, 800gr \/m3, installation is simple and efficient, saving time and money. No additional waterproofing is required. Shortens the time of work.<\/li>\n\n\n\n
- Low risk<\/strong> \u2013 unlike membranes that can be damaged, delaminate, etc., concrete protection is not required when backfilling foundation walls.<\/li>\n\n\n\n
- Reactive <\/strong>\u2013 remains dormant in the concrete until it comes into contact with water, when it is reactivated each time and closes cracks. It closes small microcracks up to 0.4 mm.<\/li>\n\n\n\n
- Lasting <\/strong>- permanently remains an integral part of the concrete. It is not subject to aging and deterioration. It is not necessary to renew it in the future, nor any other waterproofing.<\/li>\n\n\n\n
- Sure <\/strong>\u2013 Radmyx \u2122 is non-toxic and safe even for use in drinking water tanks. Prevents the penetration of harmful substances into concrete (water, chlorides, sulfur). Resistant to positive and negative hydrostatic pressure. The crystals act deep within the concrete structure, not just on the surface.<\/li>\n<\/ul>\n\n\n\n

Radmyx\u2122 as a coating or plaster<\/h2>\n\n\n\n
PRODUCT DESCRIPTION<\/strong><\/p>\n\n\n\n
Radmyx\u2122 coating is a ready-made mixture composed of Radmyx\u2122 concentrate, cement and sand. <\/p>\n\n\n\n
When used as a coating, the finished powder mixture is mixed with water in the ratio: 1 liter of water to 2.25 to 2.5 kg of powder mixture. Mixed in the form of a cement coating, it is applied with a brush to the concrete wall in two layers. <\/p>\n\n\n\n
When used as a plaster, only the amount of water is reduced compared to the coating. <\/p>\n\n\n\n
Radmyx\u2122 coating is an effective water\/moisture protection that can be applied on both the positive and negative sides of water pressure and is intended for underground parts of a building protected from thermal loads.<\/p>\n\n\n\n
After crystallization, the Radmyx\u2122 particles remain at rest in the concrete until they are activated by contact with water again, and they start the sealing process - crystallization again.<\/p>\n\n\n\n
CONSUMPTION<\/h4>\n\n\n\n
1 kg of Radmyx\u2122 coating is required for 1 m\u00b2 of surface for 1 coat (2 coats must be applied).<\/p>\n\n\n\n
KEY ADVANTAGES<\/h4>\n\n\n\n
- \n
- Easy <\/strong>\u2013 installation is simple and efficient, saving time and money.<\/li>\n\n\n\n
- Reactive <\/strong>\u2013 once applied, Radmyx\u2122 continues to react in the concrete for as long as the concrete itself lasts.<\/li>\n\n\n\n
- Multilateral <\/strong>\u2013 can be applied on both the positive and negative sides of water pressure.<\/li>\n\n\n\n
- Sure <\/strong>\u2013 Radmyx\u2122 is non-toxic, safe for use in drinking water tanks as well as in ponds.<\/li>\n<\/ul>\n\n\n\n
HOW DOES RADMYX\u2122 COATING WORK?<\/h4>\n\n\n\n
Radmyx\u2122 coating applied to a damp wall binds with water (moisture) that fills the pores and capillaries of the concrete. Through the process of osmosis, the active particles of Radmyx\u2122 coating move from areas of high concentration (from the application site) to areas of lower concentration (pores and capillaries filled with water). In contact with water, they form insoluble fibrous crystals that prevent further water penetration through the concrete.<\/p>\n\n\n\n
