Self Waterproof Concrete

Self Waterproof Concrete

Technical Information

Low permeability concrete (ASTM C – 1202)

Reinforced Concrete Class 1:

  • • Volumetric Weight higher to 2.2 tons/m³
  • • Elastic Modulus min.  14000 √ƒ´c kg/cm²
  • • ƒ´c min. 250 kg/cm² or more
  • • Max. Drying Contraction 0.001
  • • Complying age: normal to 28 days, quick to 14 days ART to 7 days, 72 hours and 24 hours

Reinforced Concrete Class 2:

  • • Volumetric Weight of 1.9 to 2.2 ton/m³
  • • Elastic Modulus min.  8000 √ƒ´c kg/cm²
  • • ƒ´c min. 250 kg/cm² or more
  • • Max. Drying Contraction 0.002
  • • Complying age: normal to 28 days, quick to 14 days ART to 7 days, 72 hours and 24 hours
  • • The structure must be saturated for 7 days to generate crystals

Advantages

  • • Water proof concrete from the moment the elements are mixed
  • • Medium-term savings (avoids the use of surface under sealers that are applied every 2-4 years)
  • • Its water proof qualities are not affected by erosion or abrasion
  • • There is no need of any other type of  water proof method
  • • It permanently protects the reinforcement steel against corrosion
  • • There is no need to apply crude membranes
  • • Cracks of up to 0.7 mm are self sealed
  • • It reduces contraction cracks
  • • Concrete resists hydrostatic pressure
  • • Ideal for applications with water table
  • • It stops the penetration of water (positively or negatively)
  • • It resists the attack of chlorides and sulfates
  • • It reduces building times of projects
  • • It does not need further maintenance
  • • Concrete is hydrated faster
  • • NSF approved for contact with drinking water
  • • It protects reinforced steel

Uses

  • • Flooring systems like solid floor slabs  and terrace gradients, steel slab, joist and top slab, and other pre manufactured systems
  • • Walls and gables
  • • Building restructuring
