Radcon uses water to waterproof in the same way Volclay (volcanic bentonite clay) reacts.
Only instead of being on the surface Radcon is creating the same barrier within the first few millimeters of Radcon penetrated concrete.
Given that tests confirm 14mm to 17 mm product penetration in 40 m.p.a. concrete, any water or salts penetrating the first 2-3 mm is of no concern to the structures lifetime durability given any reinforcement maintains 20mm + concrete top cover.
