We offer a terrific waterproof sealer for all concrete surfaces.

Our Hydroblock is ideal for new and/or existing concrete surfaces.

If you have concrete facades, parapet walls or any type of masonry surface damaged by water leaks - Hydroblock is your answer.

  • Refreshes concrete surfaces
  • Improves and draws out original colour
