About Us

Specialists in Soil Stabilization for Roads and Housing

Marewe Investments is a specialist infrastructure solutions company focused on soil stabilization for road construction and housing development. We work with engineers, developers, contractors, and public-sector bodies to transform locally available soil into reliable, engineered construction material.

Our approach is grounded in soil science, civil engineering principles, and real-world site conditions — ensuring solutions are practical, repeatable, and suitable for long-term infrastructure performance.

What We Do

We provide technical support and implementation guidance for:

Road soil stabilization and subgrade improvement
Housing foundations and platforms using stabilised soil
Stabilised earth brick (SEB) production and construction systems

Every project begins with soil evaluation. Clay content, moisture behavior, and compaction potential are assessed to determine suitability and performance expectations.

Our Approach

We believe effective soil stabilization must be:

Technically sound — based on proven soil behavior
Transparent — with clear requirements and limitations
Repeatable — delivering consistent results across projects
Scalable — suitable for both small and large developments

Why Soil Stabilization Matters

In many regions, construction costs are driven by imported aggregates, long transport distances, and unnecessary excavation.

Soil stabilization offers a smarter alternative by:

Reducing reliance on imported materials
Lowering transport and logistics costs
Improving durability and lifespan of roads and housing
Supporting sustainable use of local resources

Stabilised Soil Is the Foundation of Everything We Build

Strong roads and durable housing don’t start with imported materials — they start with properly stabilised soil. When native soil contains sufficient clay, our electro-chemical stabilization process restructures it into a dense, moisture-resistant foundation suitable for roads, housing platforms, and stabilised earth bricks. This reduces reliance on aggregates, lowers construction costs, and improves long-term performance. Instead of guessing, we test — and instead of replacing soil, we upgrade it.

FAQ

Everything You Should Know About Marewe Soil Stabilizers

ROAD STABILIZATION
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.
