Description
Medium density lightweight aggregate foundation block.
Features and benefits:
- Manufactured to BS EN 771-3.
- Range of strengths available to suit low rise and high rise buildings.
- Consists of up to 40% high quality recycled and reclaimed aggregates.
- Foundation blocks are available in a range of width and length combinations.
- Solid Armstart walls are safer, easier and more cost-effective then cavity walls.
- Solid foundation walls from 250–350 mm thick to suit cavity wall widths of 75–150 mm.
- All blocks are below 20 kg and as such comply with HSE and CDM guidelines for single unit repetitive manual handling.
- Simple and safe alternative to cavity foundation walls, no wall ties required, cavity filling or danger of collapsed cavities, faster build rates, less mortar and labour required.
