Laboratory Services

The quality of the soil on your construction sites plays a key role of your projects. Therefore identification of the soil characteristics determines the ability to support your structure. Our soil testing laboratory enables you to assess the suitability of the soil, providing you with vital data for informed decision making and planning.
