BETEC 1005 is a cement-bound synthetic modified (PCC) repair mortar which has been especially developed for repairs occurring usually under water. BETEC 1005 BETOSEA provides excellent adhesion to existing concrete constructions and does not wash out.

TypeGrain structure 
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
  • BETEC 1005 is suited for all the usual under-water repairs, such as damages to concrete in the broadest sense, for example gravel pockets, broken edges, repair of joints in brickwork etc.
  • Product ready for use, which is easy to process and environment-friendly
  • Chromate reduced
  • Checked volume increase
  • No plastic shrinkage
  • Free of chlorides and other corrosive aggregates
  • Contains no aluminous cement
  • Very good adhesion to concrete and steel
  • Because the product is cement-bound, it causes the recovery of the alkaline environment, so it will constitute the passive protection of the reinforcing steel
Packaging and storage
20 kg bags. Dry and frostproof, storage life 12 months in the original and closed packaging.
Refer to safety sheets.
Preliminary treatment of the ground
The ground should be free of contaminants such as oil, cement skin, grease, corroded concrete, loose parts etc. Remove water-bloom before application, and apply BETEC 1005 BETOSEA immediately afterwards. It should be taken into account that the material applied must be protected against flow and wave action.
