New Concrete Laboratory

Equipment and staff moved in to the new concrete laboratory facility at Trefelin in September 2014. The new location and building offers much improved facilities for both staff and services, as opposed to the former buildings at Cyttir. The new building is part of our long-term goal to gather everyone from the two sites (Cyttir and Trefelin) together at the Trefelin site. The new laboratories make for easier movement and testing of supplies, along with providing more space for both equipment and staff. In addition, the new facility allows for an increased range of tests, which can be completed more efficiently with the new equipment. Due to increased scope of testing, and the need for additional floor space, the concrete laboratory will be extended in 2015.

Please see our summary of available concrete tests below. Testing not listed below may be available upon request. To discuss further, please contact us.
