Dämmer specialism

Dämmer is a special mixture of clayey lime marl with high-quality cement class B. This mixture is dry and hydraulically binding. Adding water in the correct proportions at the project location creates a liquid mass that can be pumped. After a curing time of 28 days, a compressive strength is created that depends on the type of dämmer and the mixing ratio.

About Dämmer

Dämmer is frequently used for filling underground cavities, for example dilapidated pipes or casing pipes that are partially filled with medium-carrying pipes or cables. Dämmer is also applied to prevent subsidence of buildings and roads.

The main features of dämmer are:

  • Impermeable to water
  • Good thermal conductivity coefficient
  • Non-corrosive to metals except lead
  • Environmentally friendly
  • Non-shrink up to W/B 0,60
