The Madeira School

Highlights of our work include the following:

Main Terrace.  With its cascading view of the Potomac River and surrounding national parks, the terrace is a central point for academic ceremonies and school events.  SGH performed water testing to identify leakage paths, observed the condition of the existing waterproofing and concrete terrace slab at exploratory openings, conducted microscopic examination of extracted concrete core samples to evaluate durability characteristics, and performed non-destructive, half-cell potential testing to determine the likelihood of corrosion of embedded reinforcement in the existing concrete slab.

We developed several repair concepts for the main terrace and worked with a local contractor to prepare cost estimates for each concept.  As part of the concept development, SGH retained an architectural consultant and evaluated concepts for modifying the interior space below the terrace to make it more usable for the school.  We also retained an arborist to evaluate the impact of the repair concepts on the mature trees surrounding the terrace.

Horse Stable.  SGH invested reported masonry distress and concrete deterioration at the horse stable.  We performed non-destructive and destructive testing to gather information about the existing structure.  We analyzed the existing structural slab and supporting structure and developed conceptual options for the repair.
