System
Where the natural stone on the lower
part of the outer leaf continues with an upper
contrast of block and render (or other finish), a
cavity tray should be installed at the head of the natural stone.
Trim the SureCav sheet to the tray in the usual way.

Testimonial
We are a small design and build company living and working in the Yorkshire Dales National
Park where the use of random limestone is obligatory and planning consent for extensions
etc. is difficult to obtain and usually granted only for very small projects. I had already
specified SureCav on building regulations applications after the product had been
recommended to me by the Local Authority Building Inspector and was interested to try it on
my own extension.
I found the product to be perfect for creating a random limestone facade which abuts the
traditional rubble filled construction seamlessly yet overcomes the inherent problems of
water ingress through the limestone fissures. Additionally the reduction in depth of wall
gives space for appropriate levels of insulation whilst achieving maximum internal space.

I will continue to specify the product as the benefits far outweigh the costs and it is a breeze
to install.
