For the last five decades WDM USA's parent company has specialized in designing equipment for road condition monitoring and assessing road maintenance needs. Today the Company is widely recognized as a world leader in road condition surveying and enhancing road safety.


WDM USA’s Parent Company, W.D.M. Limited, was founded in 1945 by the late Chairman, Mr. L.A.J. Gardiner, MBE, to provide engineering support for industry and government.

It expanded rapidly in the 1950s and 1960s, designing, manufacturing and installing high-energy physics, high vacuum, remote and mechanical handling, hypersonic wind tunnel and gas purification equipment.

WDM®’s innovative development and manufacture of the SCRIM® road survey vehicle, for the Transport and Road Research Laboratory, proved to be a watershed in the Company’s development.

Since 1972, its research and development team has used its unrivalled experience and technical expertise to increase the range of advanced technology equipment, software and road surveying services.

The 1970s saw the growth of a Survey Services Department, using the Company’s equipment to provide high quality road condition assessments. Additional expertise was developed in manual inventory, road condition and road safety surveys using hand-held computers.

During the 1980s and 1990s, the Company introduced a Consultancy Service to provide a complete road monitoring and road maintenance management service for UK and international clients.

The development of the international role of the Company continued during the 1990s and 2000s. In 2017, the SCRIM® road survey vehicle successfully completed a trial in five US states and has been rated “exceptional” in quality by the US Federal Highways Administration.

The Computer Services Department has expanded to include the provision of comprehensive computerized road maintenance and integrated asset management systems.

WDM USA was set up in 2018 and will offer survey services to US highway authorities from 2019.
