At TESELA, we offer analysis and characterisation services for building materials used in new-build projects, refurbishment and heritage conservation. Our laboratory analyses mortars, concrete, aggregates, binders, stone, paint and timber using physical, chemical, mineralogical and microstructural techniques. The results enable us to diagnose defects, select appropriate treatments and verify the quality and durability of materials and products. <\/p>\n\n
Our multidisciplinary team, comprising professionals in the fields of chemistry, engineering, geology, conservation and restoration, and art history, tailors each study to the technical requirements of each project.<\/p>\n\n
Our commitment to quality and innovation<\/h2>\n\n
Our laboratory combines analysis, testing and technical support to develop new products and evaluate existing materials, processes and solutions. We work using procedures focused on quality, traceability and compliance with the technical requirements applicable to each project. <\/p>\n\n
In addition, we assist companies and technical teams with the validation of performance and, where applicable, with the technical preparations required for the CE marking of construction products.<\/p>\n\n
Materials analysis and testing services<\/h2>\n\n
We carry out laboratory analyses and on-site tests to characterise materials, identify damage, assess their physical and mechanical properties, and evaluate their performance and durability. The scope of each study is tailored to the material, its state of preservation and the technical objectives of the project. <\/p>\n\n
