Marmox Thermoblocks are central to the success of a modular housing project in Selby.

A groundworks and civil engineering specialist is innovatively using Marmox Thermoblocks to construct the oversites for a development of more than 100 affordable, prefabricated modular homes in Selby, North Yorkshire. Alfa Site Services is experienced in working with all the UK’s major housebuilders, as well as infrastructure specialists like Kier.
The company purchased 720 of the 600x100x65mm Thermoblocks from Encon Insulation of Leeds, with the merchant also supplying 50 cartons of Marmox’s versatile high-performance 360 adhesive used to bed the blocks and bond their overlapping joints. This well proven installation method achieves the accurate alignment and stability necessary for the house modules to be craned into position.
Alfa’s Senior Manager Site Services, Rick Harrison, commented, “The site was originally a railway siding, with the made-up ground requiring 2.5-metre-deep foundations, plus levels built up by a metre to deal with flood risk. This required us to lay three courses of blocks. Installing the Thermoblocks using the 360 adhesive is quite time consuming, but it’s a very good product and there have been no issues.
Once the course of Thermoblocks is complete we hand over to the developer’s site management team to install the modules. This is a significant project involving a number of technical aspects which were new to us, but I think this could represent the way ahead for construction, and we have been proud to be involved as the principal contractor.”
Marmox Thermoblocks are available in widths of 100, 140 or 215mm, and are formed from sections of XPS (extruded polystyrene) encapsulating two rows of high-strength, epoxy concrete mini-columns. These are attached at either end to the top and bottom layers of glass-fibre reinforced polymer concrete to ensure a good bond with the rest of the structure.
As well as combatting cold-bridging where the inner leaf of masonry walls abut the floor zone, Thermoblocks are also often utilised at vulnerable upper floor junctions, including beneath parapet walls, or to support timber frame construction.
