Hemelite Foundation blocks
Hemelite Foundation blocks are produced specifically for use below DPC in solid walls. They can be used to support cavity, solid or frame construction.
Hemelite Foundation benefits
- Save time and money
No wall ties or concrete cavity fill, speedy construction, no risk of collapsed cavities.
- Strong enough
Strengths of 7.3N/mm² can satisfy low and high rise building requirements.
- Safe handling
Meets manual handling guidelines for the repetitive lifting of masonry units. End grooves in block aid handling.
