Combined waterstop KAB-125 mm, 25 lm Forbuild
Hydraulic shponka KAV 125 for use in working and structural joints. KAB125 key is a key for sealing and waterproofing structural joints of concrete structures. Even at high water pressure, the combined KAB key provides waterproofing due to the expanding rubber cord and the ribbed part of the key itself. KAB key is an effective system against water penetration, and also easy to install.
- there is no need to make a suture protrusion or change the reinforcement system
- simple installation in a concrete structure with low labor costs
- stability during installation due to mounting brackets
- end heat welding joint to joint
- small bending radius
- reliable sealing and waterproofing are provided due to the ribbed part of the key and the expanding cord round in cross section
The products of the KAV series are designed for sealing and waterproofing technological joints in concrete structures of buildings and structures.
KAB hydraulic key is a key with an expanding bentonite–rubber cord for sealing structural joints in concrete structures.

Where is the KAV-125 waterstop used?
KAV tapes are successfully used in sewage treatment plants, swimming pools, reservoirs, residential buildings, etc. KAV tapes effectively seal construction seams under hydrostatic pressure up to 0.2 MPa, below the ground water level with a variable level, for example, in basements or tunnels. The tape is not sensitive to water pollution - alkaline and acidic.
How is the waterstop KAV-125 used?
In the case of installing the key before pouring the concrete of the lower KAV plate, the key is installed directly on the reinforcing bars and secured with clips with an interval between clips of 0.5 m.
In the case of installing a key during or immediately after pouring concrete, the key should only be inserted into the freshly laid concrete, after which the concrete mixture can be compacted by vibrating in the usual mode.
The marking strip located at a height of 3.0 cm from the edge of the key serves as a depth control of the installation.
The maximum depth of immersion in concrete of the lower part of the key with an expanding profile is 4.0 cm.
