EXPERT WITNESS & LITIGATION SUPPORT
Defensible Analysis & Testimony for Complex Construction Defect Claims
Waterproofing and drainage systems typically account for less than 5% of a total project’s cost, yet over 95% of all construction litigation is driven by water intrusion. When a building envelope fails, the resulting structural damage, high-cost remediation, and health hazards demand objective, science-backed investigation.
Terra-Petra’s Waterproofing Division provides premier expert witness and litigation support for complex construction defect cases. Recognized as industry authorities on the entire building envelope—from sub-slab vapor barriers and podiums to exterior fenestrations and roofing systems—our team consults with attorneys, developers, and contractors to deliver clear, defensible insights into why systems fail and who is responsible.
