Shale Testing

Shale heave or sulphate attack can occur when the fill material beneath a hard floor contains sulphates and these migrate into the concrete. The sulphates react with the concrete, causing it to expand and this results in heave of the slab and structural damage to the external walls as the slab pushes them out.

If you have a property where potential shale heave or sulphate attack has been identified, we can help guide you through the process to rectify the problem. This would usually involve a survey and samples being taken of the floor. We would then send them for analysis before determining what, if any, treatment is required.
