Weather Pro+250 Integral waterproofing liquid admixture for concrete and mortar which is used to minimise permeability and increase the waterproofing properties of concrete and cement sand mortars for critical applications like roof slabs and screeds, basements, external plastering, bathroom floors, water tanks, sumps, drains etc.

Usages and Advantage

Liquid admixture:
  • Instant and complete dispersion throughout the mix.
  • Uniform waterproofing throughout concrete matrix.
  • High efficiency: Dramatic reduction in permeability of concrete/ mortar Improved
  • workability: Improves compaction of concrete and mortar, even where harsh sands or aggregates are used.
  • Improved concrete quality: Minimises porosity and honey combing. Produces dense homogenous concrete.

Standard Compliance

Weather Pro+250 complies with IS:2645-2003.

Features & Benefits

  • Better Dampness Prevention
  • Enhance concrete strength
  • Denser concrete
  • Better prevention from rusting
  • Reduces water cement ration
  • Easy-to-mix
  • Higher durability

Weather Pro+250 is a dark brown liquid based on lignosulphonates which mixes readily with water and therefore disperses evenly. Weather Pro+250 waterproofs by improving the quality of the concrete or mortar. It reduces the water demand for required workability and minimises segregation and bleeding. Thus, it is more efficient compared to traditional powder water proofers as its use results in two-fold improvement of concrete or mortar.

The optimum dosage of Weather Pro+250 to meet specific requirements is 200 Ml for 50 kg of cementitious material in the concrete mortar mix. WP +250 is mixed into the gauging water required to prepare concrete or mortar. Maintain water cement ration less than (<0.5).

Over Dosages

Dosage outside the normal range quoted above can be used to meet particular mix requirements. Over dosage may cause delay in the setting time and segregation. Contact Brij Additives for advice in these cases
