1. Soil Stabilisation Characteristics

The CONSOLID soil stabilisation / soil consoldation system was expressly developed for soil stabilisation. Every cohesive soil possesses the characteristic to petrify again. It requires a very long time and high pressure.

Through the addition of catalysts can we speed up this process. The CONSOLID soil stabilisation system does not react as binder or oxidant. The CONSOLID soil stabilization system speeds up the natural process of solidification of all kinds of cohesive soil. It improves and consolidates the soil.

2. Basis Components

The CONSOLID SYSTEM for soil stabilisation is always effected by two products, which are used together.

It is either CONSOLID 444 and SOLIDRY or CONSOLID 444 and CONSERVEX. CONSOLID and CONSERVEX are liquid components and SOLIDRY is a powder like component.

The two components are mixed with the soil. Afterwards the soil is completely compacted. The CONSOLID soil stabilisation System can be used by almost every kind of soil.

3. Suitable Soils for the CONSOLID Soil Stabilisation System

In principle all cohesive or semi-cohesive soils or soils with a certain amount of silt (0.002 – 0.1 mm) lead to a permanent soil stabilisation.

The optimal soil mixture is 1/3 clay and silt, 1/3 sand (0.2 – 2 mm), and gravel and stones (2 – 200 mm)

Missing fractions are easily mixed in from nearby soils.

4. Frost Resistance 

According the present knowledge and the research of the University of Karlsruhe (1996), Dresden (1997), and other universities, we presume that the effect of CONSOLID soil stabilisation system and the frost resistance is given in long terms.

Through the limited water permeability, the water can only limited soaked in to build ice lenses. In this range, the CONSOLID soil stabilisation system is on the same level as concrete. The thermal conductivity of the embankment treated with the CONSOLID soil stabilisation system is much lower and therefore the time to freeze the subgrade too.

5. Environment

The CONSOLID SYSTEM stays in harmony with the nature.

The Swiss Federal Office of health attested the environmental compatibility of the CONSOLID soil stabilisation system in July 1987.

The verification was produced with the Eluat-Test. Non of the substances was washed out.

Since then, many other states have tested the CONSOLID additives too.

5. Road Construction

Advantage of CONSOLID soil stabilisation system in relation to Concrete for road construction

  • Mixed soil can be stored for unlimited time

  • No slab effect

  • Environment compatible

  • Easy to apply in the field

  • Longtime effect

  • Large tolerance in the variation of soil

  • No problems in the dosage of additives



CONSOLID 444 is a chemical substance, which breaks up the adhering water film and leads to an irreversible agglomeration of fines, reducing the capillary rise of water substantially.

The high effectiveness of CONSOLID 444 protects the soil, especially against the soaking in of water. It allows better compaction of the treated soil and increases desired density during the time and under traffic.

In comparison with untreated soil, CONSOLID 444 has the following characteristics:

  •  Better compactibility through changing the water characteristic in the soil

  •  Strong reduction of water absorption through reducing the capillary activity

  •  Reduced water permeability

  •  The Proctor Optimum of treated soil is lower and the density is higher

  •  Strong reduction of water sensibility

  •  Strong reduced swelling and shrinking behaviour


SOLIDRY is a dry, chemical/organic substance, which preserves the treated soil and increases the soil specific bonding characteristics.

SOLIDRY prevents the treated soil from water soaking in by closing the capillary. The capacity of water absorption is drastically reduced, which stops the swelling behaviour of the soil.
