A standard architectural expansion joint cover bridges structural gaps and accommodates movement — it does not provide waterproofing by default. When a joint is exposed to rainwater, groundwater, or wet-service conditions, waterproofing must be specified as a separate function. This article explains the essential components of a waterproof expansion joint: a continuous elastomeric water barrier, a controlled drainage path, and the often-overlooked yet critical end dam. It also covers key material properties — continuous contact pressure, chemical compatibility, and maintenance limitations — and clarifies the design boundaries of seal systems in standing water. Only correct selection and installation can truly stop water at the source. Read More
