Testimonials See how one contractor found using SureCav to protect from wind driven rain Love this product, my local building control officer recommended it for my stone built project. The product was easy to install and made the building of the stone walls quick and easy. I’m now using it on all projects. Nice to see a product that does what it says! Glen Davison SureCav is a fantastic product and as we said in the CPD it has very much become a 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. Louisa Meek, CSA architects I have 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. Jonathan Athay, JMA Design, North Yorkshire We have just built a new build using SureCav25 and found it superb to use, allowing us to increase insulation thicknesses within the build, enabling us to achieved a great EPC (energy performance) result. We also found it very easy to use as it guaranteed a clear cavity throughout the build and it also saved us using a backing block for the stone façade, actually increasing the internal rooms sizes by at least 200mm. Overall, we found the SureCav a fantastic system – thanks SureCav! Tony Iles, Director, Tonic Construction Limited SureCav is a fantastic product and would use it on all jobs. Ross Parkyn, Director, Duchy Brickworks I really can’t recommend the SureCav product enough! Our self build project has been stressful to say the least with the rising costs of labour and materials, we’ve had to do whatever we can to save where we can. I thought a good way to do this would be installing the SureCav myself, however with never using the product before I was unsure of how straight forward this would be. I am happy to say it was an absolute breeze! The stonefacing looks great against it and the stone lads said it gave them a great flat structure to work against. This really is a 10/10 A*** product that we couldn’t be happier with and recommend enough. Andy Holcroft, self-builder in Cumbria I am so impressed with this product I would be happy for you to bring any of your prospective customers to my site at Wool, Dorset, and I will be pleased to show them your system. Chris Allworthy, Barratt Homes Site Agent We have used SureCav on a new stone house which was shortlisted for an RIBA Award. SureCav is a very good way, without the need for all of the additional foundations, and loss of floor space in the building associated with a blockwork backing to the external masonry. This saves time, space and money plus it gives the additional layer of weather protection provided by the SureCav sheets. We are currently using SureCav. We are very pleased with the high quality stonework. SureCav makes it easier to achieve the effect we want.
