Details

The CEMflex VB elements are coated with special protection on both sides.

The CEMflex VB is an active steel waterstop joint!
The sealing function is based on the active crystallization process, as well as the natural sintering process of concrete.
CEMflex VB Features:

The extremely adherent behavior to concrete is responsible for the excellent waterproofing property.
CEMflex VB supports the natural sintering / crystallization of the joint, as well as cracks.

Installation of the CEMflex VB joint:

  • The CEMflex VB with coating on both sides must be installed directly on top of the reinforcement.
    The CEMflex VB must be fixed with the omegas of the steel plate support system.
    The amendments are made by overlapping, which must be at least 5 cm.

The adherence of the special coating to the concrete prevents any flow of water through the concrete construction joint. In addition to the total adhesion to the steel sheet of the special coating and to the surrounding concrete, there are other chemical reactions, such as expansion, crystallization, self-sealing of concrete cracks and natural sintering / crystallization (natural limestone formation) of concrete cracks.

Only 3 cm of concrete overlay on both sides is required to seal the joint and guarantee up to 5 bar (50 m of water pressure)

The elements are 2000 mm long, 150 mm high and about 1.25 mm thick. The special coating is not sticky and therefore no protective foil is required.

Composition of the CEMflex VB joint

Galvanized steel sheet metal (b = 0.75 mm / l = 2000 mm / h = 150 mm) provided on both sides with a special coating 0.5 mm thick that chemically adheres to the concrete and permanently seals the joint.

Installation examples:

  • Labyrinth sealing
  • Crystallization sealing
  • Active support of natural sintering / crystallization, as well as limestone formation
  • Extreme single connection when incorporated into concrete
  • General test certificate according to the building code (abP)

CEMflex VB

The CEMflex VB steel plate reacts because of its various components encapsulated in the patented coating (direct contact with the surrounding concrete components).
In addition to the excellent bonding of the special coated steel sheet to the concrete, there are some chemical reactions initiated as expansion, crystallization, self-correction of concrete cracks and the natural sintering / crystallization (natural limestone formation) of concrete joints, as well as, as of cracks.
The components of the special coating need water or water-based liquids to automatically initiate the chemical reaction; This natural crystallization process is an active process of self-healing!

CEMflex VB is a waterstop joint made up of an “active” steel plate, which reacts with water!
This active self-sealing process starts automatically by contact with water. The function of this sealing process is guaranteed even after decades of installation.
With the use of CEMflex VB, there will always be a reaction / waterproofing process (active) automatically. Crystallization, self-healing of concrete cracks will penetrate more and more deeply into the concrete structure.
The waterproofing reaction of the CEMflex VB steel waterstop joint was tested at the independent / public institution and is confirmed with an abP (Certificate / Approval of the General Construction Certificate)
