Soil Stabilisation and CBR Testing

Explore our comprehensive range of expert groundwork and civils services

Improving Ground Conditions for Safe Construction

At United Civils, we provide soil stabilisation and CBR testing services to ensure your site has the strength and consistency required for safe development. Whether preparing roads, yards, or building plots, we treat and test the subgrade for long-term performance.

 

Ground Strength You Can Build On

Operating throughout Nottinghamshire, Yorkshire, Lincolnshire, and Derbyshire — and nationwide for large projects — we help contractors manage poor or variable ground with stabilisation techniques and accurate testing. From lime/cement treatment to in-situ testing, we ensure every formation is construction-ready.

Key Features of Our Stabilisation and Testing Services

What Is Soil Stabilisation?

Soil stabilisation improves weak or moisture-sensitive soils by adding binders (typically lime or cement) to increase strength, reduce plasticity, and support loading. It is commonly used to:

  • Strengthen formation layers

  • Improve workability of wet or clay-heavy soils

  • Reduce the need for spoil removal and import

  • Achieve consistent compaction and CBR values

  • Prepare ground for roads, slabs, and hardstanding

We assess ground conditions, recommend a treatment mix, and apply binders mechanically using stabilising machines or excavators — then rotovate, level, and compact the material.

 

Lime and Cement Stabilisation Services

We carry out full in-situ stabilisation across sites of all sizes. Our services include:

  • Site investigation and ground review

  • Supply and mixing of lime, cement, or hybrid binders

  • Mechanical blending with rotovators or bucket mixing

  • Moisture control and re-compaction

  • Level trimming and tolerances

  • Follow-on CBR testing to verify strength

Stabilised layers can then support Type 1, concrete, or surfacing — reducing long-term settlement risk and improving durability.

 

CBR Testing for Subgrade Validation

California Bearing Ratio (CBR) testing is used to assess the load-bearing strength of soil. At United Civils, we carry out both:

  • In-situ CBR tests – with immediate results on prepared ground

  • Laboratory CBR tests – for bulk samples if required

These tests are often required by engineers, clients, or warranty providers (e.g. NHBC) to confirm readiness before placing roads, slabs, or other load-bearing features.

 

When Stabilisation and Testing Are Needed

These services are typically required on:

  • Sites with clay-heavy or wet subgrades

  • Roads and car parks requiring high formation strength

  • Poor fill areas or made ground

  • Projects seeking to reduce dig-and-cart-away

  • Fast-track schemes with ground condition risk

We offer standalone testing, full stabilisation, or both as part of an integrated groundwork package.
