Waterproof Tape

 Secure and effective waterproof tape sealant solutions

In addition to providing our clients with industry leading void creation solutions, we’ve also developed a weatherproof tape. Not only does this effectively join the Commercial and Residential Clayboard® panels together, but it also seals the polythene wrapping.

The waterproof tape is 50mm in width, provides 66m of tape per roll and can be readily supplied alongside any Clayboard order.

I used Clayboard for the first time on a residential site last month. After ordering with Trisha from Travis Perkins, I was very impressed as the void former was on site in a few days. I have used other ground heave solutions before but none of them had delivered a true void, so I wanted to make sure I installed the product correctly. I had a quick look over the installation guidelines over a cuppa and I discovered the product was very easy to install. The product is lightweight and the fact it comes on weatherproofed pallets, makes my job easier when it arrives on site.

We like to deal with the market leading product manufacturers and the fact that we have been stocking and distributing Clayboard for as long as we have is testament to our relationship with Dufaylite. We always maintain healthy stocks of Clayboard, but there will be times when we need support from Dufaylite with a speedy replenishment. They are also quick to respond to quotation requests or questions about the product from our groundworks customers.

I started to work with Clayboard on a number of sites about five years ago. I had been aware of other ground heave solutions previously, however after reading about the benefits of Clayboard on the website and getting to know Nigel at Clayboard, I realised Clayboard delivered numerous life cycle benefits to a project, plus it is technically a true void former.

I am often in contact with Nigel. He is reliable and extremely knowledgable of the product and the industry. Clayboard is competitively priced allowing the site to retain the cost benefits from less land excavation and ground prep, the level of service I receive from the team at Clayboard, the technical support of the product and the fast delivery times to site, help to ensure the site maintains its tight schedule.
