Product Description ● Environmentally friendly
● Maintains integrity of building envelope
Cavity Protection System
● Suitable for any external masonry leaf

Reasons to choose SureCav for your construction project
SureCav is a polypropylene panel that sits in the cavity and allows a stone, slate, brick or flint
outer skin to be built without the need of an additional block leaf.
NEW: SureCav25 forms a 25mm residual cavity, accepted by LABC!
Environmentally friendly:
● Made from 100% fully recycled plastic
● Light weight easy to transport - 100 times lighter than 100mm concrete backing blocks
● Incorporates a new fold line that makes it easy to construct corners
● Will save you money, guarantee clean and moisture free cavities and create up to 6% extra internal
floor space with narrower footings, when original external dimensions used
● It significantly reduces labour and material costs and gives a faster cleaner build
● SureCav guarantees absolute integrity of the cavity by providing clean moisture free cavities that also
stop water penetration from wind driven rain
● It is durable and remains effective for the life of the building

Gone are the days when builders had to use
concrete blocks or even a messy system of
temporary shuttering or plywood that often
weakened the wall when removed, as well as
allowing mortar to fill the cavity.

Construction materials
The SureCav Cavity Wall Spacer System is designed for use in new, external cavity wall construction. The
system ensures a minimum residual cavity width of 25mm when using natural or reconstituted stone outer
leaf in conjunction with:
● Conventional masonry inner leaf, with or without partial fill cavity wall insulation
(masonry includes clay, calcium silicate, concrete and stone units)
● Timber-frame, SIPS or ICF inner leaf or Steel Frame construction
The system may also be used with conventional clay and calcium silicate brick and concrete block outer
leafs. The system can be used in any exposure zone in buildings with a 25mm cavity instead of the usually
required 50mm or 75mm.

Testimonial
“SureCav is a fantastic product and as we said in the CPD it has very much become standard
detail for stonework within the office. Perhaps now with knowledge of the further advantages
of waterproofing and stability it may become more widely specified for other cavity wall types
also. Many thanks for all your help and we hope that our support of your product will continue
to push SureCav as a recognised standard for cavity wall construction within the industry.”
