HOW OUR ROAD SOIL STABILIZATION WORKS

Unlike mechanical compaction alone, our process triggers an ionic interaction with clay particles present in suitable soils.

At a molecular level:

Clay particles naturally carry surface moisture
The stabilizer alters electrical charges
Particles bind more tightly together
Voids are reduced and density increases

The treated soil behaves as an engineered road base, not loose earth.

THE ROAD CONSTRUCTION CHALLENGE

Road failure typically begins below the surface. Weak subgrades absorb moisture, lose density, and deform under load — leading to rutting, potholes, and premature failure.

Replacing soil is expensive, slow, and environmentally disruptive.

Building Stronger, Better Roads!

Technical Requirements for road stabilization

For optimal performance:

◈ Soil should contain approximately 10–15% clay
◈ Excessively sandy soils may require blending
◈ Moisture control and compaction are critical
◈ This ensures predictable, repeatable outcomes across projects.

How does it benefits your projects?

◈ Improved load‑bearing capacity
◈ Reduced permeability and water damage
◈ Lower reliance on imported aggregates
◈ Reduced maintenance cycles

What Our Clients Say

“Using stabilised earth bricks allowed us to reduce material and transport costs while still achieving solid structural results. The build process was efficient and predictable.”

Stephen Flores — Property Developer

“The soil stabilization approach reduced our need for imported material and simplified construction. The road base performed exactly as specified, even under heavy traffic.”

Marissa Young — Municipal Infrastructure Manager

“From an engineering perspective, the stabilized soil showed improved density and load-bearing capacity. The process was straightforward and repeatable across the site.”

Whitney Romero Consulting Civil Engineer

“Construction moved faster because we weren’t waiting on aggregate deliveries. Compaction was consistent, and the base layer met our requirements without overdesign.”

Jabulani Ncobo Roadworks Contractor

“Cost predictability was a major advantage. By using local soil, we avoided unexpected material price increases and logistics delays.”

Julian Sithole Private Development Director

“The housing units constructed with stabilised soil met our durability expectations and helped us stay within budget. This approach is well suited to scaled housing delivery.”

Ismail Dawood PPublic Housing Project Coordinator

FAQ

Everything You Should Know About Marewe Soil Stabilizers

Housing Stabilization

ROAD STABILIZATION

What is soil stabilization in road construction?

Soil stabilization improves the strength and performance of the road subgrade by modifying the soil’s structure. This creates a denser, more moisture-resistant base layer beneath the road surface.

What type of soil is suitable for road stabilization?

Soils with moderate clay content typically respond best to stabilization. Very sandy soils may require blending or additional treatment to achieve the required performance.

How does soil stabilization improve road lifespan?

By increasing bearing capacity and reducing moisture penetration, stabilized soil is less prone to rutting, deformation, and early failure. This results in reduced maintenance over time.

Is soil stabilization a replacement for imported aggregates?

In many cases, yes. Where soil conditions are suitable, stabilization reduces or eliminates the need for imported base materials.

How do we determine if our road project is suitable?

Suitability is confirmed through soil testing, including clay content, moisture behavior, and compaction characteristics prior to construction.

Housing Stabilization

What is soil stabilization for housing construction?

Soil stabilization strengthens native soil for use in housing foundations, platforms, and stabilised earth brick production. This improves structural reliability and durability.

Can stabilized soil be used for building houses?

Yes. When correctly engineered and compacted, stabilized soil is suitable for housing foundations and stabilised earth brick construction.

What are stabilised earth bricks (SEBs)?

SEBs are compressed bricks made from stabilized clay-rich soil. They offer high strength, durability, and improved thermal performance compared to conventional materials.

Do stabilized earth bricks require mortar?

Interlocking stabilised earth bricks can be dry-stacked or require minimal mortar. This allows for faster construction and reduced skilled labour requirements.

How do we know if our site soil is suitable for housing?

Soil suitability is determined through testing for clay content, moisture behavior, and compaction potential before construction begins.
