Polyurethane (PU) waterproof coating is a liquid-applied, highly elastic membrane used to create a seamless, watertight seal over surfaces. Because it transitions from a liquid to a durable, rubber-like solid, it is often preferred over traditional "sheet" membranes (like bituthene or DPC strips) for complex areas where leaks are common.
