Product Features

The STELLAR FOUNDATION 350 block is specifically designed to reduce weight and still achieve the technical requirements of a 350mm load-bearing masonry cavity wall construction. This unique design has a cellular element at its core that only runs through 90% of the length of the block. This means the block has a hole on one side, but has a solid face on the opposite end and also includes finger grips running along the edges for ease of handling.


The STELLAR FOUNDATION 350 block is suitable for a minimum 125mm to a maximum 150mm wide cavity construction. When undertaking a cavity construction between 125mm & 140mm the inner and outer leaf are to be equally brought in from the outer edges.
