Bone Dry Structural Admix

Bone Dry Structural Admix is a low VOC porosity reducing admix (PRAH) which eliminates the path of moisture vapor transmission (MVER). Extend concrete service life by up to 80% with this structural admix. Our product prevents concrete degradation caused by salt and chloride ingress found in coastal, marine and salted road environments. Protect finished flooring, roofing and resinous material from moisture vapor transmission and bonding-related issues with our structural admix. Our product contains no silicates or alkalis and is suitable for normal or lightweight concrete. 

How to Apply Bone Dry Structural Admix

  1. Apply separately from other admix
  2. Mix at a 10 oz per 100lbs cwt. 
  3. Add as a 1-1 replacement to water

Additional Benefits

On-Site Mixing Add admix to batch. Allow 7 minutes before pouring
Plant Mixing Add structural admix to tailwater


  • Concrete must contain a water-to-cement ratio between 0.31 - 0.53
  • Admix ratio has a dosage range of +/-3%
  • Do not use shrinkage-reducing admixtures, crystalline growth admixtures or retarding admixtures containing Beta-naphthalene sulfonate with Bone Dry Structural Admix
  • Bone Dry Structural FX is compatible with curing compounds. ACI 302.2R-06 or dissipating curing compounds are recommended. Permanent cure and seal products are not recommended when installing moisture-sensitive flooring.
  • Use the manufacturer's specified adhesives for finished flooring installation.
  • Bone Dry Structural Admix is compatible with resinous coatings but slabs must be mechanically profiled to CSP 3 prior.
