THE CHALLENGE OF SOIL STABILISATION
Soil stabilisation is fundamental to the performance and durability of roads, pavements, foundations and earthworks. Many construction projects encounter problematic soils such as expansive clays, sulfate-bearing soils or weak granular materials, which can exhibit low bearing capacity, excessive deformation, shrink–swell behaviour and long-term durability issues.
Traditional stabilisation methods using cement or lime can improve strength, but they often require high material dosages, may be chemically incompatible with certain soils, and carry a significant environmental and carbon cost. There is therefore a clear need for more efficient, durable and sustainable soil stabilisation solutions.
QUANTCRETE® TECHNOLOGY IN SOIL STABILISATION
QUANTCRETE® TECHNOLOGY IN SOIL STABILISATION
QUANTCRETE® is a nano-engineered additive designed to enhance soil performance through microstructural modification rather than bulk material replacement. When used in soil stabilisation applications, it acts at particle level to improve density, bonding and overall engineering behaviour.
MECHANISM OF ACTION
MECHANISM OF ACTION
NANO-SCALE DENSIFICATION
QUANTCRETE® contains ultra-fine nanoparticles with a very high specific surface area. These particles penetrate the soil matrix and occupy micro-voids between soil grains, resulting in:
Reduced porosity and permeability
Improved particle interlock
A denser, more stable soil structure
This densification leads directly to improved strength and stiffness.
ENHANCED INTER-PARTICLE BONDING
The nano-additives promote stronger bonding between soil particles and any cementitious components present, improving load transfer and resistance to deformation under applied stresses.
IMPROVEMENT IN ENGINEERING PROPERTIES
IMPROVEMENT IN ENGINEERING PROPERTIES
QUANTCRETE® soil stabilisation provides measurable improvements in key geotechnical parameters, including:
Increased California Bearing Ratio (CBR), enhancing load-bearing capacity
Reduced swelling potential in expansive and sulfate-bearing soils
Improved compressive and tensile strength of stabilised soil layers
These improvements enable soils to meet performance requirements that might otherwise necessitate soil replacement or thicker pavement and foundation designs.
CHEMICAL COMPATIBILITY AND DURABILITY
CHEMICAL COMPATIBILITY AND DURABILITY
One of the limitations of traditional cement and lime stabilisation is their susceptibility to adverse chemical reactions in sulphate-rich or highly reactive soils, potentially leading to expansion, cracking and long-term degradation.
QUANTCRETE® is more chemically compatible with a wide range of problematic soils, helping to:
Minimise harmful secondary reactions
Improve long-term durability
Reduce the risk of premature failure
This makes it particularly suitable for challenging ground conditions where conventional stabilisers may be unsuitable or unreliable.
SUSTAINABILITY AND ENVIRONMENTAL BENEFITS
SUSTAINABILITY AND ENVIRONMENTAL BENEFITS
QUANTCRETE® is effective at very low dosages compared with traditional stabilisers. This offers several sustainability advantages:
Reduced use of cementitious materials and associated embodied carbon
Lower transport and handling requirements
Improved ability to stabilise in-situ soils, reducing the need for excavation and disposal
From a life-cycle perspective, improved durability and reduced maintenance requirements further enhance environmental and economic performance.
PRACTICAL CONSTRUCTION BENEFITS
PRACTICAL CONSTRUCTION BENEFITS
The use of QUANTCRETE® in soil stabilisation delivers tangible project benefits, including:
Reduced pavement and foundation thickness due to improved subgrade performance
Faster construction by enabling the use of existing soils
Lower whole-life costs through improved durability and reduced maintenance
These advantages are particularly relevant to road construction, industrial pavements, housing developments and infrastructure projects built on marginal or problematic soils.
CORE INSIGHT
CORE INSIGHT
QUANTCRETE® is a compelling alternative to conventional soil stabilisation methods. It addresses soil performance at a sub-microstructural level. Through nano-scale densification and enhanced bonding, it improves strength, reduces swelling, enhances durability and offers a more sustainable approach to ground improvement.
QUANTCRETE® hence enables more efficient designs, reduced environmental impact and improved long-term performance in a wide range of soil stabilisation applications.

QUANTCRETETM EARTH
QUANTCRETETM EARTH
APPLICATIONS : In Adobe, Rammed-Earth and Road Construction, this system serves as an environmentally-friendly soil, cement & concrete nanoadditive to mitigate sulphate attack. It increases the California Bearing Ratio (CBR) value of the treated sublayer soil in particular, acid sulphate soils. It minimises the swelling ratio of soil and initiates essential chemical reactions creating compounds that form strong bonding forces between soil particles, hence reducing soil porosity which consequently improves its engineering properties and durability.
It serves as an expansive agent to reduce autogenous-shrinkage, Increases Compressive & Tensile Strength, Corrosion Inhibitor (Mitigate sulphate attack) & pH Elevator, Mold and Mildew Resistance, Low Air Permeability, Abrasion Resistance, Antistatic Agent, Halogen-Free Flame Retardant.
