Abrasion Testing


Abrasion resistance is an important concert requirement in warehouse and industrial floors. Floors can be exposed to quite belligerent actions from trucks and other equipment, particularly in factory environment. The depth of wear is used to assess the quality of the floor and classifies it in accordance with BS 8204-2:2003+A2:2011. Each test is accompanied by a Face Consultants report. Where the categorization is lower than required, Face can investigate and advise on the significance of the results, and on any remediation steps that should be taken.

Cover Meter Testing

A cover meter is an instrument to locate rebars and measure the exact concrete cover. Rebar detectors are less complicated devices that can only locate metallic objects below the surface. Due to the cost-effective design, the pulse-induction method is one of the most regularly used solutions.

Drop Testing

Dense floor screed on visual inspection may appear to be able to withstand imposed loads of traffic, but in reality may in fact be sub-standard.

When laying sand cement screed, specifications state that the consistency should be semi dry. However, when the screed is manually packed in it may result in the lower layers being insufficiently compacted. This may cause the screed to fail under the impact of heavy traffic or future movement, and could require following remedial work on the screed which is often costly and time consuming.

Slip & Skid Resistance Testing

The Munro Stanley Portable Skid Resistance Tester (also known as the British Pendulum Tester) is a scientific instrument for assessing the slip or skid risk posed by any surface.
Floor and paving material must comply with slip and skid resistance criteria in both dry and wet conditions. The Ethical Stone Company is able to provide a fully compliant slip and skid testing service; either for in-house tested samples or on-site interior and exterior situations.

Surface Regularity Testing

Surface Regularity or flatness of screeds is an important aspect that determines the serviceability of a floor. When it is practically impossible to achieve screeds or flooring that are absolutely flat or true to datum, it is important to prevent excessive deviation as it can affect the serviceability of the floor both directly and indirectly.

Surface Roughness Testing

Surface roughness testers consist of a stylus which is instinctively drawn across the surface recording an ‘image’ of the surface roughness across a pre-defined sample length. The dimension technique provides a number of measurement parameters including:
Rmax: The greatest distance between the highest peak and lowest valley over the sampling length.
Ra: The average surface roughness over the sampling length.
Rt: The distance between the highest peak and the lowest valley within any given sampling length.
Rz: The average distance between the highest peak and the lowest valley over a number of sampling lengths.

Pull Off Adhesion Testing

Pull Off Adhesios is very simple to use, quantitative range giving a definitive adhesion value, ideal for the laboratory or field on flat or curved substrate applications. Tensile Dollies (or stubs) are glued to the coating and, when the adhesive has cured, the force mandatory to pull the coating off the surface is measured.

Relative Humidity Testing

The newest concrete test method in recent years for floor products is in-situ (in-concrete) relative humidity testing. The relative humidity meter is versatile in that it can take measurements, store them to memory and then transfer data to a computer for further detailed analysis. There is also the calibration standard for the relative humidity meter which makes it easy to ensure that measurements are accurate.
