Quantum Ground Stabilisation

The Quantum Ground Stabilisation was expressly developed for soil stabilisation.

Every cohesive soil possesses the characteristic to re-petrify naturally but for that to happen, it takes a very long time under high pressure. Through the addition of catalysts, the Quantum Ground Stabilisation speeds up this process dramatically.

The Quantum Ground Stabilisation does not react as a binder or an oxidant; It speeds up the natural process to solidify all types of cohesive and semi cohesive soils, permitting an improvement of the load bearing strength by figures up to, 5 - 10 fold relative to untreated material. Using the cohesive nature to naturally bind materials together, making all particles a solid immovable base layer.

The Quantum Ground Stabilisation is a two part process Quantum Emulsion (QE) and Quantum Powder Formulation (QPF).

QE is a chemical substance that 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 QE protects the soil, especially against the soaking in of water. The ionic exchange in clay and other soils repels water instead of attracting it, allowing for better compaction of the treated soil and increases desired density during time and under traffic, never degrading always improving the strength of the base.

QPF is a powder substance that does not absorb water but binds with soil particles, this prevents the treated material from water soaking in by closing the capillary. The capacity of water absorption is drastically reduced; which stops the swelling behaviour of the soil, allowing the natural plasticity of the material to bind everything together.

The Quantum Ground Stabilisation (QGS) System is a two part system that beneficiates the load bearing capacity of natural gravels and soils for road making purposes:

• One part lubricates the particles enabling greater compaction and moisture impermability
• The other, a powder, fills capillary voids mitigating against soil moisture movement
• The nett result is significantly improved shear strength of the natural material

The QGS System is not a cementing agent:

• Is therefore not prone to the shrinkage problems associated with cement
• It can be reworked in service without loss of integrity
• For repair use, treated material can be stockpiled for unlimited time prior to compaction

The QGS System improves the bearing capacity of natural gravels and soils by:

• Enhancing compaction through reduction in the capillaries between soil particles
• Mitigating soil moisture increase thus maintaining the integrity of the natural cohesion and inter-particle friction

The QGS System demonstrates these benefits through:

• Substantially improves CBR's
• Increased Unconfined Compressive Strength
• Improved shear strength
• Virtual elimination of permeability to ground water and rainfall

The QGS System is a chemical substance which breaks up the adhering water film leading to an irreversible agglomeration of fines thus substantially reducing the capillary rise of water and allowing better compaction of the treated soil and increases required density under traffic.

In comparison with untreated soil, QGS 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 Density Optimum Moisture Content of treated soil is lower and the density is higher
• Shrink and swell behaviour significantly improved with a malleable remediation of the treated material

QGS inorganic powder prevents the treated soil from water ingression by closing the
capillary. Water absorption is drastically reduced, preventing swelling of the soil.

1. How to define SOIL STABILISATION?

"Soil stabilisation" is achieved if an in-situ Soil has been rendered usable for risk free application in any earthwork.

2. How to achieve SOIL STABILISATION?

In the past 50 years many attempts at improving the behaviour of soils have been undertaken with the aim to avoid the substitution of conventional construction material for unsuitable in-situ soil, i.e. soil of lower quality. The products chosen for this purpose can be divided into the following groups:
Products gluing together the soil particles, such as binding agents, and Products gluing at a change of the chemical composition of the soil, thus reacting with the soil, and improving its properties.

Some products out of these two groups show both effects, e.g. hydraulic binders. What all these products have in common is the fact that they can be used only under certain conditions, i.e. with certain soil types and certain granulations of the soil. They often fail to yield satisfactory results because soils rarely have a homogeneous composition, and this makes it impossible to anticipate the effect.

3. What are the advantages of the Quantum Ground Stabilization System?

The Quantum Ground Stabilization System (QGS), comprising the combinations a liquid formulation and powder formulationm was developed and devised specifically for the purpose of soil stabilisation avoiding the paths other products (binders and chemical reactants) had gone with questionable outcomes.

Any cohesive soil has a tendency to petrify again; all it needs to achieve this goal is a very, very long time span and very high pressure. It is possible, however, to accelerate this procedure by catalytic processes. If the soil can be activated by catalysts or pseudo-catalysts and influenced in complex processes in its undesired behaviour, a considerable improvement can be achieved with nearly all kinds of soil and with the same quantities of additives.

This is what QGS does:

The use of the liquid formulation results in an irreversible agglomeration of the fine particles of the clay and in this way, a reduction of the active soil surface. The adhering water film is destroyed to a very high extent, thus activating the inherent binding power of the soil and the water content in the soil, especially its capillary saturation, is virtually diminished. An additional treatment of the soil with the powder formulation enables a 'tailored' degree of stabilisation in accordance with the requirements of each particular construction site.
