Сòòò½APP

Aggregates are a fundamental resource to the built environment and are a significant  constituent in widely used construction materials such as concrete and asphalt. Aggregate properties heavily influence material properties during the construction and in-service performance. Understanding aggregate properties by testing plays a vital role in the construction industry by providing owners, designers, and contractors with valuable information throughout a project’s progress. Сòòò½APP offers physical, mechanical, and chemical aggregate testing services to ensure that your building materials perform as expected, are safe and fit for purpose. 

Сòòò½APP combines an unrivaled track record in materials testing with the ability to produce precise and accurate tests to make critical determinations about construction materials selection, engineering performance, and compliance with compulsory regulations and quality standards. 

We have skilled engineers with in-depth knowledge of the properties and composition of the different types of construction materials who provide professional advice and technical support to ensure complete satisfaction in your finished construction project.

Сòòò½APP provides a full range of concrete and aggregate testing services on-site and in our well-equipped, fully accredited laboratories. Our comprehensive package of physical, mechanical, and chemical aggregate testing helps determine the properties of aggregates and confirm compliance with your project or current standards.

With the experience of testing aggregate consignments from a few tones to many millions of tones in specialist quarry export facilities, you can be assured that customer testing is being carried out to the highest level upon which you can take informed factual decisions with certainty.
