Krystol Broadcast is a crystalline waterproofing treatment for concrete flatwork. Krystol Broadcast is applied as a dry-shake to the fresh concrete surface and trowelled into the concrete during the final finishing. The dry broadcast method produces a smooth finished floor suitable for typical traffic or application of common floor finishes. Krystol Broadcast replaces the need for conventional membrane waterproofing systems, and is best suited for thick concrete slabs that will be power-trowelled during finishing.

When combined with fresh concrete, Kryton’s unique and proven Krystol® technology reacts with un-hydrated cement particles to form millions of needle-like crystals. Over a period of weeks and months, these crystals grow, filling the naturally occurring pores and voids in concrete, and permanently blocking the pathways for water and waterborne contaminants. Later, if cracks form due to settling or shrinkage, incoming water triggers the crystallization process and additional crystals begin to grow, filling cracks and ensuring that the structure’s waterproofing barrier is maintained and protected.
