In 1983 Densit A/S was founded as an independent company in FLS Industries, which is one of the largest industrial groups in Denmark. The main activities of FLS Industries include cement-manufacturing machinery, building materials and aerospace, employing over 14,000 people worldwide.
For 20 years Densit A/S has specialised in developing cement-based materials with Ultra-high strength and durability, for industrial strengthening and repair. Its purpose was to exploit DSP (Densified Systems with Ultrafine Particles) technology.
DSP technology makes it possible to manufacture cement-based materials with strength and durability five to ten times greater than that for mortar and concrete. In addition, DSP materials have especially good anti-corrosion qualities and can be used without risk to the environment.
The binding material in conventional concrete and mortar consists of cement with a relatively large amount of water and is therefore rather porous. In Densit® materials, the use of DSP technology, with its ultra-fine powders, reduces the waster content of the binding material to an absolute minimum. The result is a high level of density, quite unusual in cement-based materials.
