RHEOWITT Cable Grout


RHEOWITT CABLE GROUT is a so-called non- (wet) shrinking injecting mortar based on portland cement, but it can also be injected and moulded because of its excellent fluidity. RHEOWITT CABLE GROUT has been specially developed by Wittekind and Deys Betontechniek BV and tested according DIN EN 445:2008-01 and DIN EN 447:2008-01 to inject prestressing concrete.

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
  • Injecting mortar for channels for prestressing steel (piles for example)
  • Injecting mortar for anchorages
  • Injecting mortar for severall concrete connections
  • Product ready for use, which is easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • Geen bleeding, after pressing not necessary anymore
  • No plastic shrinkage
  • High early and final strengths, therefore loading is possible soon after application
  • Can be used both for horizontal as well for vertical injections
  • High fluidity
  • 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
  • Can be pumped, vibrated or poured without any danger of de-mixing
Packaging and storage
2 x 25 kg kg bags plus 500 gr additives.Dry and frostproof, storage life 6 months in the original and closed packaging.
