Sulphate Testing in Concrete Floors
Sulphate attack on ground floor slabs is a critical problem which can lead to serious structural damage in the main walls of a building. The problem is caused when the fill material (hardcore) beneath the slab contains sulphates and these migrate into the concrete. The sulphates react with the concrete causing it to expand resulting in a "heave effect" in the slab and structural damage to the external walls as the slab pushes them out. Eventually the concrete may disintegrate. When the slab heaves, any internal walls built off the slab will be lifted and may cause damage to the structure above.
Our report thoroughly examines the evidence and explains the exact impacts within a building.
This is a cost effective examination which can mitigate serious structural problems in the future.
