How Drymix and Drymix Ultra Work
Drymix and Drymix Ultra additives transform concrete into a self-healing, waterproof barrier.
When added to the mix during production, these additives trigger a chemical reaction that seals the capillaries and micro-cracks within the concrete.
The result? A structure resistant to water, chemical attack, and the effects of time, capable of self-healing micro-cracks up to 400 microns.

The Heart of the System: DRYBOXSYSTEM®
DRYBOXSYSTEM® is an integrated approach that covers every aspect of concrete waterproofing. It includes:
- Design
- Drymix and Drymix Ultra additives.
- Solutions for joints, construction joints and critical details.
- Technical support during the construction phase.
- Ten-year post-construction warranty
This combination guarantees the client total waterproofing of the structure for 10 years, also reducing future maintenance costs.
