Building Industry

YALI® is a light, pozzolanic natural product with an excellent CO² balance and an ideal additive for cement- and lime-bonded products. YALI® is also used in the form of naturally pure granules in mortars and plasters and in road construction.

In Europe, the United States of America and the Arab States, the outstanding properties of YALI® are used to manufacture high-quality building products that meet international standards and the requirements of modern construction.

YALI® is a pure natural product without organic and inorganic contamination.

YALI® insulates, is heat and frost resistant, does not burn or carbonise and can also be used in exposed masonry due to its white colour.

YALI® does not emit any hazardous emissions, is fully recyclable and does not pose a water hazard.

In the Industry

YALI® can be used for finishing textiles, polishing stone products and metal, and in the chemical and pharmaceutical industries.

YALI® in everyday life

Jeans and fabrics of all kinds can be washed with YALI® to make them supple; marble and granite can be surface treated with YALI® and cosmetics and toothpastes can contain YALI® to achieve the greatest possible care effect.


YALI® is a chemically inactive material, has a neutral pH value and low electrical conductivity. This makes YALI® the ideal inorganic component for base layers and can optimise your production. For this reason YALI® is successfully used, for example, in plant cultivation. In agriculture YALI® is particularly suitable because of its following properties:

  •     free from inorganic and organic contaminants,
  •     constant grain fractions,
  •     Long-term properties,
  •     low costs and
  •     great availability.


YALI® is used in garden and landscape design as a base layer, for example in

  •     hydroponic vegetable plantations, such as tomatoes, aubergines, cucumbers, melons, etc.
  •     hydroponic flower plantings, such as roses, daisies, etc.
  •     plantations for potted plants.
  •     plant nurseries for raising seedlings for plants.

YALI® is a pure natural product without organic or inorganic impurities, which, if the appropriate irrigation procedures are followed, ensures adequate aeration and water supply for the root system of plants.

Roof Greening

YALI® is very well suited as an aggregate for green roofs due to its low raw grain density, uniform grain size distribution, chemical purity and stability, especially in frost and high external pressure.

Geotechnical engineering

Lightweight Filling Material

YALI® is a purely natural product whose physical, chemical and mechanical properties make it an ideal and lightweight filling material for numerous geotechnical applications.

Characteristics of Yali®:

  • Bulk density, grain density and grain strength
    The bulk density of YALI® is between 650 kg/m3 and 830 kg/m3 for the dry product (105° /24 hours), the average raw grain density is between 0.98 and 1.01 and the average grain strength is 21.2 kN. These properties reduce loads and lateral stresses, minimize transport costs and facilitate handling. Thanks to its excellent thermal insulation properties, YALI® offers protection against extreme temperature fluctuations.
  • High internal friction angle
    YALI® is available with a uniform particle size distribution, a property which, together with the high internal friction angle, increases the cohesion and stability of the product without the use of minerals.
  • Chemical Inactivity
    YALI® is frost and heat resistant, does not corrode and is not chemically attacked. It also has pozzolanic properties.


These excellent properties of YALI® are used in the United States, Europe, the Mediterranean region and on the Arabian Peninsula as a lightweight filling material for a wide range of different geotechnical applications, e.g:

  • for road paving,
  • in road and path construction,
  • for harbour construction work,
  • for bridge construction and
  • in dam construction.

YALI® has proven to be a highly versatile and competitive material - it offers solutions for difficult land filling and embankment situations.

The properties of YALI® become particularly important in soft or unstable ground, e.g. in road and waterway construction, in order to reduce loads and prevent landslides. YALI® is therefore particularly suitable in road construction for the production of surfaces with high load-bearing capacity for roads and building plots on soft and wet subsoil.
