Hixtra Ltd 
Construction & Geotechnical Testing 
If you need to assess aggregates, stone or crushed concrete for use as capping, sub base, Type 1 or working platform material then we can help. We undertake a broad range of classification tests to asses whether material complies to a variety of specifications inducing, the 6F classes, MOT sub bases and aggregates used for other purposes such as in concrete. 
 
Take a look below at the types of tests we offer from our central laboratory and on your site to help with aggregates assessment.
