HYPERSOIL®
Stronger roads start with the soil on site.
A soil optimiser used with cement or lime to turn the ground already on site into a durable, load-bearing base.
German technology, distributed in Australia by TIME Technologia.
Build from the ground you have
A conventional road base is dug out, hauled away and rebuilt in imported layers. HYPERSOIL treats the soil already there, mixed in place to a depth of about 40 cm, with no excavation and no haulage of soil.

Bound at the particle
Milled into the ground with water on the first pass, HYPERSOIL, a water-based and solvent-free wax emulsion, binds the soil’s microscopic particles at the nano level.
An illustrative specimen. It follows the sequence GAT describes; it does not show the chemistry.
Encapsulated in cement or lime
On the second pass a hydraulic binder is milled in and encapsulates the bound particles. HYPERSOIL is always used with cement and/or lime: GAT states it enhances their effect, reduces the quantity needed and accelerates curing.
Compacted, then closed to water
Final compaction pushes residual moisture out of the structure, and the stabilised layer becomes hydrophobic. GAT reports full protection against frost and far fewer micropores, essentially eliminating cracks and drastically reducing maintenance.
Stable in wet and flood-prone ground, provided the bearing capacity of the soil beneath is sound and the site was prepared to the correct standard.
Strength you can test
Initial strength after 12 hours, with full performance often measurable within three days.

Five machines. Six passes.
The mix-in-place method works the soil where it lies, with a recycler, a water truck, a binder spreader, a grader and a roller compactor.
- 1
First recycling pass
The HYPERSOIL–water mixture is milled into the existing soil, to a depth of about 40 cm.
Recycler, water truck
- 2
First compaction
The treated soil is pre-compacted for passability and initial particle encapsulation, then rests.
Roller compactor
- 3
Spreading binder
A hydraulic binder, such as cement, is spread over the treated soil.
Binder spreader
- 4
Second recycling pass
The binder is milled into the treated soil, which is compacted once more.
Recycler, roller compactor
- 5
Grading
The surface is levelled to the design gradient.
Grader
- 6
Final compaction
The layer is compacted a last time, pushing residual moisture out of the structure.

GAT reports up to 80% shorter construction time, 20–50% lower project costs, the most on larger projects, and up to 90% less CO₂.
In each square metre
- HYPERSOIL
- about 300 ml per m²
- Cement
- about 25 kg per m²
- Water
- about 30 L per m²
- Coverage
- about 3 m² per litre of HYPERSOIL
- Output
- about 4,000 m² a day per work column
GAT’s indicative quantities and published comparisons, not a mix design: a construction manual with the method and material ratios is supplied, and results depend on the soil, the design, the logistics and the scale of the project. GAT’s information(opens in a new tab).

Before you break ground
Where is HYPERSOIL made?
It has been developed and manufactured in Germany since 1995, using renewable energy and sustainably sourced organic raw materials, with ISO 9001:2015 manufacturing. GAT reports more than 30 projects worldwide. TIME Technologia is the Australian distributor.
What comes with the product?
GAT provides a comprehensive construction manual, with its construction method and the calculations for the material ratios. The treatment depth, soil, water and binder requirements are established for the actual site.
What is the environmental impact?
GAT reports CO₂ reductions of up to 90%, from using the soil in place and fewer machines on site. It states that HYPERSOIL is non-toxic and does not leach into the surrounding environment once installed.
How do I assess it for an Australian project?
Start with the site’s location, its intended use, the approximate area and any soil information you have. TIME can discuss your enquiry and the product information needed to consider HYPERSOIL for the project.
