Concrete & Materials Testing Services

Assess the strength of a concrete floor or wall section safely and efficiently, in accordance with British Standards.

The Omega Group has the expertise and equipment to handle a wide range of drilling projects, including cutting through the toughest reinforced concrete and rebar with precision. We use diamond-tipped core drill bits paired with state-of-the-art rotary drilling technology. Our team can create accurate holes in various diameters and depths using high-quality diamond-tipped core barrels, ensuring a clean void without cracks or jagged edges.

Safety Is Paramount

Reasons to test and validate the strength of the concrete

A building may be undergoing repurposing, or a newly installed concrete slab may have failed after 28 days. In such scenarios, it is not uncommon for a mezzanine floor, heavy factory machinery, or racking systems to be scheduled for installation. Once the strength is known, a structural engineer assesses whether the concrete is suitable.

Advantages to Diamond Drilling

  • Cost-effective when compared to other forms of site investigation.

  • Create clean and accurate holes thanks to sharp diamond drill bits

  • Minimal dust and heat output due to water cooling the core bit.

  • Cut through the strongest reinforced concrete and materials.

Free Schmidt Rebound Hammer Survey Included

As part of our diamond-drilling and coring service, we provide complimentary Schmidt rebound testing before drilling. The Schmidt rebound hammer is a non-destructive testing method that allows quick, easy assessment of concrete surface strength. By using this tool, we can provide an immediate estimate of concrete compressive strength, supporting quality assurance and informed decision-making on site.

Important: Schmidt rebound hammer testing offers a quick, non-destructive estimate of concrete strength. While convenient and non-destructive, it does NOT replace the accuracy and reliability of compressive testing performed on concrete core samples, which remains the universally accepted industry standard for determining concrete strength.

Ensure Project Success

We can cut a variety of dimensions and lengths to suit your project needs

We can cut down and into depths to suit you, utilising extension rods to enable deeper penetration and cutting of sub-layers and beyond, dependent on slab depth.

Important: For compressive strength testing, the core sample must have a minimum length of 100 millimetres or 1:1 ratiio to ensure accurate results.

Core diameters we commonly cut

  • 50.0 mm

  • 70.0 mm

  • 100.0 mm (most common)

  • 150.0 mm
