Sealing system for sealing expansion joints and method for placing the same

摘要

The present invention relates to a sealing system provided with a self-expanding seal for sealing expansion joints in buildings, said seal consisting of a first body 11 and a second body 12 which are elongated and arranged opposite one another, connected by means of a waterproof flexible body 30 and by means of expanders 20 that produce an elastic thrust for separating said first and second bodies which are thus trapped inside the expansion joint to be sealed. Said seal includes retainers 40 which keep it in a pre-compressed position, allowing easy placement within the joint to be sealed, and which may be released producing the instantaneous expansion of the self-expanding seal.
