Concrete structures are only as watertight as the waterstops that join them. In most concrete structures and elements, a particular type of joint (construction, contraction, control, expansion or isolation) will be designed in them for a number of varied structural design reasons, and due to this joint, it may need to be water stopped as the structure is water retaining or water excluding.
Waterstops are very important and are usually required for most projects. There are many types of waterstop systems to be considered for use, and a very specific type may need to be used for the joint that has to be water stopped.
Beijing Langwei is a waterstop specialist and has a wide and varied number of waterstop systems available for use, for many different types of construction segments.
