In-House Laboratory Facilities
Building Science Laboratories is a division of RDH focusing on research and development, building science communication, and training. Our in-house laboratory testing facilities include a climate chamber, various building monitoring sites, and a full-scale test wall facility, all designed to help us test and evaluate building materials and construction methods.
RDH’s expertise and equipment has enabled us to take on projects investigating masonry wall deterioration on many historic buildings throughout North America. Careful assessment at the materials and assembly level can help to manage risk and make informed decisions about how to incorporate conservation treatments and performance upgrades into older buildings.
Masonry Durability / Freeze-Thaw Testing
When planning an interior insulation retrofit for an existing masonry building, it is important to analyze the freeze/thaw durability of the masonry units. The critical freeze/thaw saturation value is an important measure of durability, and frost dilatometry is an effective method of determining this value. The typical frost dilatometry process involves a site review and material sample collection, testing of masonry units, hygrothermal analysis, and communication to inform project teams of the opportunity risks associated with various thermal insulation and other related retrofit measures.
