Masonry construction or concrete blockwork is a traditional form of basement construction in the UK.
It can be used with Type A waterproofing protection, for cases in which it is recommended that render or a similar smooth, continuous layer is applied to the blockwork face to provide continuous support to the waterproof membrane. Walls are typically reinforced and particular care is required at corner details and the wall slab junctions to cope with ground pressure.
Masonry walls can also be effective as internal lining to create a drained cavity basement wall (Type C).
Please refer to Part A (Structure - Walls and foundations) of our building regulations guide for further information. All information correct as of 2013 amendments.
