Upon application, DIS enters the surface porosity and follows the capillary system in search of unused calcium hydroxide, (CH). DIS uses the CH as a catalyst and forms calcium silicate hydrate. This process continues for 30 to 45 days and can reach 4 to 6 inches in the concrete. Once the calcium hydroxide is converted, it becomes a permanent part of the concrete and will never break down or exit the concrete. This process will also fill the porosity and the capillary system making it virtually impermeable, permanently. The alkali is stabilized and locked into place, and even moisture vapor is reduced to acceptable levels. This insoluble gel that the DIS forms becomes a very unique colloidal barrier that will halt, or minimize some of the concrete’s challenges like ASR, efflorescence, plaster dust, silting, calcium nodules, and excessive water migration. DIS is an excellent product for water proofing concrete pool shells, existing pool finishes, new finishes, concrete or shotcrete water features.
