Explore our comprehensive range of expert groundwork and civils services
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.
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.
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.
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.
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.
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.
We provide a full range of professional groundwork and civils services tailored to meet the unique needs of commercial, residential, and public sector projects. Operating across Nottinghamshire, Yorkshire, Lincolnshire, Sheffield, Derbyshire, and offering nationwide coverage for larger commercial projects, our team delivers exceptional results every time. From kerb installation and bulk earthworks to drainage solutions and car park groundworks, we’re committed to precision, quality, and reliability on every site.
