Technical Paper: "Re-thinking Use of a Soil Cap."

Below is a technical paper re why using a cap of good soils placed on expansive soils does not always work -- structurally and/or economically.

The paper has a definite bit of ground-breaking research and presentation of facts combined with a little smoking gun. It includes several diagrams showing the effects of heaving soils on a variety of slab designs -- a first in the many papers of this type we’ve seen, and a feature that really adds to the ability to visualize and comprehend a very technical topic. It also includes great info regarding Wafflemat, and how the System performs in these conditions.
