Soil Stabilization Solutions
Superior soil stabilization performance
Global Road Technology (GRT) is a recognised leader in the field of polymer soil stabilization around the world. Extensive investment in research and our international experience has helped us formulate some of the most effective and advanced soil stabilization agents available.
Our advanced soil stabilisation products are ideal for a variety of applications, from public road pavements to hardstands and lay-down areas, right through to unsealed haul, rural and service roads.
GRT PCM is designed to provide greater resistance to tensile failure, increase overall strength and prevent cracking. This is a revolutionary polymer stabilisation technology specifically developed for use with either pozzolanic agents such as cement or lime.
By offering a greater resistance to tensile failure GRT PCM can provide savings, by enabling significantly reduced pavement thickness.

Are environmental regulations, health and safety concerns or potential profit loss a concern right now?
Soil Stabilisation with GRT PCM
There are significant, long-term benefits that come from the application of GRT's revolutionary polymer stabilisation technology solutions.
- Fatigue crack reduction
- Induced crack reduction
- Shrinkage crack reduction
- Water proofing
- Increase compressive strength
- Increased tensile strength
- Increased resilient modulus
- Reduced pavement thickness
PCM significantly improves soil stabilization by enhancing resilience against cracking caused by shrinkage and flexing. High internal stresses, which typically arise during the hardening process, are mitigated through the crosslinking process between long-chain polymers, pozzolanic cements, and water. This results in hydration products that are less brittle as they form around the soil particles, ensuring superior soil stabilization performance.
Resilience to failure from external forces such as; settling, heaving subgrades, and high traffic volumes is greatly enhanced. More cost effective designs are now possible where a stabilised base layer can be constructed to full pavement thickness without the concerns of reflective cracking.

GRT stabilization products transform end of life, out of spec roads and pavements into safe, durable infrastructure, in a cost effective manner.
All roads and pavements age and are compromised over time or by increased traffic volumes, resulting in a range of symptoms including dust, potholes, rutting, corrugation or total pavement failure. This can also result in vehicle accidents, can cut off communities, and impact on the flow of goods people.
With GRT’s polymer soil stabilization technologies, you can alleviate these very real social, environmental, and economic concerns.
GRT stabilization products can either be in-situ blended into the existing road material or added into new materials through a pugmill at a quarry or stockpile site.

Materials are then spread, compacted and trimmed to required design specification. With a skilled crew able to lay an impressive 7,000m2 per shift, it can offer significant savings that range between 4 and 10 times cheaper when compared to traditional bound pavements such as asphalt and concrete.
