The Moisture Level System was developed in 2004 by inventor Mr. Bob Brown to control expansive soil heave under concrete slabs. The system uses a variation of sub-slab depressurization to induce superficial drying in expansive clay soils under slabs. The development, design and multi-year testing results of the Moisture Level System are presented in this White Paper.
