Wrapping Solutions

Keeping Clayboard secure

As Clayboard is designed to lose its compressive strength when it comes into contact with water, it’s essential that it is kept dry if it’s going to perform correctly once installed.

We appreciate that construction sites are busy, exposed areas and are often at the mercy of the weather, and have developed a bespoke wrapping solution to protect our panels.

We use lay flat tubing to pre-wrap boards in our custom built factory. Boards are inserted into a long, robust 500 gauge polythene container with the ends securely sealed. Our wrapping system has enough slack to allow for the packaged to be ‘z’ folded onto the transit pad. We can handle three panels at a time as each one is lightweight and easy to handle.

When delivered to site, any excess slack can be trimmed and resealed. If the panel is too long, the package can be opened and the end panel cut to length. The lay flat tubing can be suitably resealed with waterproof tape.

Our wrapping solution effectively prevents the exposure of large areas of Clayboard, reducing the sealing to a confined area at any one time. The lay flat tubing can accommodate the full width of a 1m wide panel for laying under slabs, but can also be used under narrow sections and beams.

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.
