Quality control

During manufacturing only high-quality aggregates are used, which meet the strictest requirements. During the production process as well as during the final stages these materials are extensively tested for quality, not only in our own laboratory, but also in independent acknowledged institutes.

Application areas Advantages
  • As an overlay of 2-20 mm thick
  • Reprofiling damaged concrete
  • Filling hollow spaces
  • Filling air pores
  • Product ready for use, which is easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • No plastic shrinkage
  • Resistant to frost and gritting materials, like salt
  • Free of chlorides and other corrosive aggregates
  • Contains no aluminous cement
  • Complies with the requirements drawn up for prestressed concrete
  • Very good adhesion to concrete and steel
  • Highly resistant to oil and grease
Packaging and storage
20 kg bags and 10 kg plastic buckets for the 302 WHITE. Dry and frostproof, storage life 12 months in the original and closed packaging.
