WEBSpring joints are panel joints where we intentionally create a slight hollow in the middle of the glue joint. This hollow is slight enough that under clamping pressure the gap between the boards is closed. This puts the ends of the panel joint in compression which will resist the greater movement cause by loss and gain of moisture at the end grain.
