Developing the Xbloc in the past led to extensive research within DMC on single layer armour unit behaviour under different circumstances and with different design concepts. Research has also generated new design options as Eco Xbloc and Xbase.
Since July 2008 DMC also executes research in its own 2D wave flume.
Other institutes which have been performing model tests on Xbloc are:
- Deltares, Delft, The Netherlands
- TU Delft, The Netherlands,
- DHI, Denmark
- University of Edingburgh, Scotland
- CSIR, Stellenbosch, South Africa
- Queens University, Belfast, Northern Ireland
- Water Research Laboratory University of New South Wales, Sydney, Australia
- Aalborg University, Denmark.
- Manly Hydraulics, Sydney, Australia
- HR Wallingford, United Kingdom
- Indian Institute of Technology, Madras, Chennai, (ITT Madras) India
- Lanka Hydraulic Institute, Colombo, Sri Lanka
