When you live in a clay soil area, some unique challenges present themselves during construction projects. In particular, the pressure exerted by concrete on those clay soil can create a process known as clay heave during the life of the building.
The solution is to use a clay heave board and one of the best known is Claymaster. Let’s look at what it is, how it works and how you install the products.
What is Claymaster?
Claymaster is a clay heave protection product that is used to prevent issues with a building’s foundations when they have been built into clay soils, especially those with a high ratio of mineral particles. This movement happens due to the pressure of the concrete and the moisture that is naturally present and can cause real structural problems to the building if left unchecked.
The products tend to be used where there are shrinkable clays. These are soils that have a large proportion of mineral particles but that is also less than 0.002mm in diameter. This soil is very solid when it is wet but the problem comes when it dries out, leaving a crumbly structure that isn’t great for foundations.
The solution is to use a Claymaster product to reduce the pressure from the concrete. 75mm Claymaster Board is the most popular while the 50mm Claymaster and 100mm Claymaster boards can be used in different situations.
Benefits of Claymaster boards
Claymaster boards are a popular way to deal with this problem because they offer a permanent solution to the issue of clay heave. The boards are easy to install and there’s very little compression due to concrete casting.
Furthermore, there’s no specialist equipment or even knowledge needed to install them. The boards are moisture resistant and lightweight as well as being very durable so they make for a cost-effective solution to the issue. They are also A+ rated in the BRE Green Guide to Specification.
How to install Claymaster
Claymaster boards are a pink colour to make them easy to spot and have enough compressive strength to withstand up to 600mm of wet concrete being placed directly onto them.
To install them around piled ground beams, trenches should be excavated as normal accommodating the thickness of Claymaster being used. The trench needs to have a flat bottom and granular fill or even concrete added to the bottom to achieve this.
Boards are laid at the bottom of the length, making sure that the full width is lined and the boards butt tightly together. The ground beam should then be placed with the right side, normally an inside face, lined with Claymaster to the required depth.
Supports and restraints are used to then keep everything in position during the placement of the concrete and spacer blocks can be used at the sides or vertical Claymaster boards positioned after the ground beam is cast.

FAQ
All of our C16 and C24 graded timber is regularised
Regularised timber is timber that has been processed to have a uniform shape and size. This means that the wood has been sawn and planed to remove any irregularities and ensure that each piece of wood has consistent dimensions. Regularised timber is often used in construction, particularly in the framing of buildings, as it is easier to work with and can be more efficiently installed than irregularly shaped timber.
We have one of the largest ranges of timber lengths, dimensions and grades available to buy online.
The variation you require will determine the exact lead time and delivery method.
