Bostik BLOCK C902 (previously Sovereign Hey’di Powder X) is a rapid-setting plugging compound with almost instant curing. It is used to stop water ingress through concrete and masonry, prior to tanking with the Sovereign Hey’di K11 Tanking System. Bostik BLOCK C902 can be applied as a dry powder or mixed with water into a wet paste and used as a plug. It sets in seconds of contact with water, forming a waterproof plug preventing water ingress.
