Biokil Crown Integral Waterproofer - Concentrated Liquid Waterproofing & Plasticising AdmixtureBiokil Crown Integral Waterproofer

Concentrated Liquid Waterproofing & Plasticising Admixture for Mortar, Render & Concrete

A highly concentrated integral waterproofer and plasticiser for use in cementitious mixes. It enhances workability, reduces water permeability, and provides long-term resistance to water ingress—even under freeze/thaw cycles—while maintaining breathability.

Key Benefits

• Waterproofs & plasticises mortar, render, screed & concrete
• Reduces shrinkage, cracking & bleeding in fresh mixes
• Improves freeze/thaw resistance with stable air entrainment :contentReference[oaicite:1]{index=1}
• Reduces water absorption & permeability, including under hydrostatic pressure :contentReference[oaicite:2]{index=2}
• Air entraining, non-corrosive additive—won’t affect steel reinforcement :contentReference[oaicite:3]{index=3}

Product Details & Coverage

• Form: Concentrated liquid admixture
• Pack Sizes: 5 L and 25 L
• Coverage: Dilute at 1:40 (0.6 L concentrate to 24.4 L water); approx. 2 L gauging solution per 50 kg cement :contentReference[oaicite:4]{index=4}
