ABA WATERSTOP

WATERSTOP SELECTION
The selection of a appropriate water-stop is governed by the type of joint, location of water-stop,
concrete thickness, type of concrete, reinforcement position, expected movement
(expansion/shear) as well as water-head/pressure to which it is to be exposed to. It is supplied in four types of D, A, DA & AA.
-Sunken sealing strip for expansion joints (Type D)
-Sunken sealing strip for construction joints (Type A)
-Surfaces sealing strip for expansion joints (Type DA)
-Surfaces sealing strip for construction joints (Type AA)

INSTALLATION
ABA WATERSTOP must be installed so that they are securely held in their correct position while the concrete is being poured.
 The concrete must be fully compacted around the ABA WATERSTOP to ensure that no air holes or porous areas remain.
 Where reinforcement is present, an adequate clearance must be left to permit correct compaction.
Welding and installation of ABA WATERSTOP shall always be coordinated with mould setting and laying of reinforcing bars for the best results.
