Vulkamineral LB 0/12

Blowable - certified per RAL-GZ 253

Product specifications   Applications
Das Bild
  • Open-pored granular mixture with homogeneous grain size, contains natural pumice and light lava stone; resistant to wind erosion.
  • The particles have a roughed surface, with open pores, are load-bearing, structurally stable, resistant to dislocation and are frost-resistant per DIN 52104.
  • Vulkamineral has a high water retention capacity, which is only exceeded by that of pure pumice, and good water permeability with a high air volume.

Product uses  Das Bild

  • Water-retaining drainage layers, monolayer systems,
    e.g. for injection sowing, enlargement of rooting
    space with use of a Vulkanmineral drainage layer, prevention of waterlogging, densification of soil and improvement of gas exchange in poorly ventilated soil.
  • Basis for high quality substrates
  • Urban tree renewal and planting
  • For internal space planting in layers of 2 – 12 mm
