In this episode of the Concrete Logic podcast, we brought on Brent Rollins and Scott DiLoreto from Spray-Lock to discuss colloidal silica. If you are like most folks, you probably never heard of colloidal silica (CS). It is a product that can be sprayed on concrete during concrete placement or long after the concrete is cured. It can even be used as an additive to ready-mix concrete.

Once CS is applied to the concrete, it penetrates and fills up the microscopic (nano) voids it finds in the concrete and essentially makes the concrete waterproof! Although CS keeps water from penetrating the concrete, it still allows water in the concrete mix to escape just like it normally would in the curing process.

After this interview with Brent and Scott, your head will start spinning on how you can use colloidal silica in your future projects.
