Is Your Concrete Up to Scratch?
Whether you’re pouring for a brand-new build, assessing an existing structure, or confirming compliance with BS EN and European standards, you need to know your concrete’s actual properties, not just assume them. Concrete testing, from slump tests on fresh concrete through to cube testing of hardened samples, gives you that certainty before it becomes a problem.
At STS (National) Ltd, our team specialises in concrete testing and concrete cube testing across every stage of a project, from fresh concrete on site to laboratory analysis of hardened structures. We assess compliance, flag defects such as reinforcement corrosion, and give you data you can act on before it costs you time or money.
We also test for cement content, air content, and density, covering the full range of physical and mechanical properties your building control team or consultant will ask for.
Our Concrete Testing Services
We carry out testing at every stage, from casting and sampling of fresh concrete to laboratory assessment of hardened structures, supporting compliance with BS EN 12390 and your project’s own requirements.
1. Fresh Concrete Testing
Before concrete cures, it’s critical to assess its workability and consistency.
Concrete Slump Testing: We carry out slump tests on site as each batch arrives, checking consistency so you know immediately if the mix is too dry or too wet, and can adjust the cement, water, or aggregate content before it’s too late.
Air Content & Temperature: We measure air voids and temperature, both of which affect the durability and performance of the finished structure under varying exposure and curing conditions.
2. Strength & Compression Testing
Evaluating hardened concrete is central to safety, durability, and project compliance.
Concrete Cube Testing: The industry standard for measuring compressive strength. We cast, cure, and crush cubes on calibrated compression machines to BS EN 12390, giving you results your building control team will accept without question.
Concrete Compression Testing: For structural elements or pavements, our UKAS-accredited results confirm your concrete meets the required mechanical properties.
Concrete Break Testing: Carried out in a controlled environment to determine the point of failure for cubes or other specimens, validating the safety margin of your materials.
3. In-Situ & Structural Investigations
Existing concrete in structures often needs specialised methods to assess integrity, depth, and defects.
Concrete Core Testing: We extract cores at the required depth for precise laboratory analysis of an installed structure, determining density, cement content, and contaminants, useful for assessing service life in aggressive ground conditions.
Concrete Hammer Testing: A non-destructive method (Schmidt hammer) for estimating surface compressive strength, supporting quality assurance across a wide range of structures.
Concrete Pull Testing: Assesses the bond strength of screeds, coatings, or repairs, confirming the strength matches project specification at each stage.
Reinforced Concrete Testing: We locate rebar, determine depth of cover, and inspect for reinforcement corrosion, essential for structural assessment and long-term risk reduction from exposure or aggressive soil.
4. Moisture, Durability & Laboratory Analysis
Concrete Moisture Testing: We assess slabs for excess moisture, which can cause flooring defects or reduce service life, before further construction proceeds.
Cement Content & Contaminant Testing: Confirming cement content and checking for contaminants supports long-term durability and quality control across all construction materials.

Concrete Testing Frequently Asked Questions
What is concrete testing? Concrete testing covers the on-site and laboratory methods used to check the workability, strength, and durability of concrete, from slump tests on fresh concrete through to cube testing and core testing of hardened structures.
What standard does concrete cube testing follow? Concrete cube testing is carried out to BS EN 12390, the British and European standard covering cube preparation, curing, and compressive strength testing.
How long does concrete testing take? Standard cube tests and laboratory analysis are typically returned within 24 hours, so results are available fast enough to keep your project on schedule.
How much does concrete testing cost? Costs depend on the number of samples, the specific tests required, and site access. Get in touch for a free, fixed-rate quote.
