SUPER-CRETE™
Duraflex Ultra
Ultra-flexible, 2-component, polymer-modified, waterproofing cement-based slurry. Ideal for waterproofing of surfaces formed by concrete, render, gypsum board, masonry, cement blocks, metal, etc., that show or are expected to show hairline cracks due to expansion-contraction or vibration, such as flat roofs, balconies, swimming pools, above ground tanks, inverted roofs, etc.
What is Duraflex Ultra?
Duraflex Ultra is Supercrete's most advanced flexible waterproofing slurry — engineered for structures that experience movement, vibration and thermal cycling, where a rigid system would crack and fail.
Unlike standard cementitious waterproofing systems, Duraflex Ultra incorporates titanium modification and polymer enhancement that gives the cured membrane exceptional flexibility — allowing it to bridge hairline cracks that form after application due to structural movement or thermal expansion and contraction.
The 2-component formulation — liquid polymer component mixed with the powder base — creates a cement-based slurry that bonds tenaciously to a wide range of substrates including concrete, render, gypsum board, masonry, cement blocks and metal. Once cured, it forms a seamless, fully bonded waterproof membrane that cannot delaminate or shift.
As the winner of the Product Excellence Award at Architect 2025 — Sri Lanka's most prestigious construction exhibition — Duraflex Ultra is recognised as the best-performing waterproofing system in its category in the Sri Lankan market.
