Mapeproof Granules

Sodium Bentonite Granules

Mapeproof Granules are sodium bentonite clay granules used as a detailing accessory material in conjunction with Mapeproof HW and Mapeproof SW waterproofing membranes. When Mapeproof Granules come into contact with moisture, they form into a dense, low-permeable gel that produces a seamless waterproofing system when combined with Mapeproof HW or Mapeproof SW waterproofing membrane.
