Models at an exhibition

This model was produced to demonstrate the uses of a waterproof membrane. The material is represented by the blue layer.  The Sketchup model was first prepared in order to discuss the design and specifications for the physical model which followed.

The following models were also prepared for display on a trade stand. The ground was "cut away" to reveal sub-surface use of the materials.  Again, a sketchup model was valuable in planning and scaling the physical model.
