Profile: H+H UK Limited is a manufacturer of aircrete systems. Our product line includes standard grade, solar grade, hi strength grade, plus blocks, foundation blocks, floorblocks, multi-plates, jumbo blocks, vertical elements, and other accessories. Our standard grade is extremely versatile, and can be used below DPC as infill for beam and block flooring systems. Our standard grade blocks are available in thicknesses from 75 mm up to 215 mm. Our hi-strength grades are used principally where higher compressive strengths are required, such as in foundations & lower storeys of three storey buildings, piers under high vertical loads, and in multi-storey buildings.
