Some highlights are Planet Mark, for our commitment to sustainability and The National Building and Construction Awards. Awards About us Our Story SureCav’s story starts in 2000, when Charlie came up with the idea of a process to simplify the building of natural stone walls. Building with natural stone required a backing wall of heavy concrete blocks or the removal of temporary shuttering. This often damages the newly-constructed stonework, resulting in mortar contaminating the cavity, as well as water penetration. Our patented design 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. It is designed to form a lightweight alternative to backing blocks that also acts as a barrier to wind-driven rain, effectively providing a consistent, mortar and moisture-free, clear cavity. SureCav is made from 100% recycled polypropylene, designed to last the lifetime of the building and is BBA certified. SureCav is the only approved method for constructing an NHBC accepted a 25mm residual cavity. SureCav Product Range SureCav 50 The 50mm cavity spacer system.

Scroll through to discover what they have had to say about the product, benefits, service and more. My opinion is that SureCav is the way forward and is a great product and great solution. I can see this completely doing away with outdated backing block design. I have been personally really impressed with the overall SureCav system and have happily shown some of your prospective customers around. I talked to your prospective customers about the many benefits of SureCav, including it being simple and easy to erect and also, with the advantage on a tight site it taking up less valuable storage space and can be moved and handled with ease. The biggest advantage, of course, is that you can increase the overall floor area by using SureCav. Daniel Cox, Site Agent 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 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 One of the best products in the construction industry! Dan, Greenhill Construction SW Ltd 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. Phil Easton, Founding Director at Western Design 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 The speed of build, easy storage and handling make SureCav an ideal system. We have found this especially to be the case where storage and working space on site is at a premium. Ray Holmes, Hopkins Developments Having used SureCav on at least 6 contracts we will never use backing blocks or shutter boards again. Richard, EMM-LEC Ltd 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 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 We have supplied the SureCav system for several years to bricklayers across the Southwest. Not only do we find the team at SureCav highly knowledgeable and helpful, but the SureCav system gets great reviews from all our customers who install it. Customers who use SureCav will continue to use it on future projects as it is a quick, easy and professional system to instal. The service is second to none and I really can’t find a fault. Suitable for both timber frame and masonry, it really is a fantastic system. Eric Sutherland, Branch manager SureCav is a fantastic product and would use it on all jobs. Ross Parkyn, Director, Duchy Brickworks 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.
