SureCav, a cavity wall spacer system, has been designed to take the place of a backing block when building stone walls and is BBA approved 04/4154.
Made from 100% recycled plastic, the system guarantees absolute integrity of the cavity, says the company, and will keep all cavities moisture-free including water penetration from wind-driven rain.
The system ensures a minimum cavity width of 50mm and reduces the width of foundations by 100mm allowing an extra 5% floor space when original external dimensions are used.
Plus, being 80 times lighter than 100mm concrete backing blocks, it is easy to transport, store and move on site, and install.
