Genotek Blog: technical guides to expansion joint covers
Practical guides for architects, consultants and contractors who specify and install expansion joint covers. Each article answers a question our engineers are asked on projects, explains the engineering in plain terms and links to the Genotek systems and documents it refers to. The Genotek facts in every article come from our product pages and documents, and each article lists its sources at the end.

Find a system or ask an engineer
To narrow the range by gap size, load, movement, surface, fixing and watertightness, use the Product Finder or browse the full product range. Datasheets, installation instructions, drawings, MSDS and specification text for every model are indexed on the Downloads page, and our support services are on the Resources page.
For a project, send your joint schedule or drawings through the contact page or to support@genotek.global, and our engineers will propose a system for each joint.
