The sturdy natural stone mixture.
The BISOTOP® Bio leveling fill is made of a natural expanded silicate perlite mixture, is not bituminized and contains no resins or plastics.
The natural stone mixture interlocks under pressure resulting in a homogenous insulating layer with a hard surface. BISOTOP® Bio leveling fill has a much higher stability (compressive stress) compared to a pure perlite fill.
