Features & Benefits

• A highly flexible waterstop made from high-quality thermo-plastic vinyl resins, which form a product with good resistance to mechanical stresses, the aggressive action of chemical products in alkaline environments, sea-water and acids
• Used within concrete structures and is highly resistant to perishing caused by sunlight, ozone and other aggressive agents present in the atmosphere and water table
• The dimensions and type of Idrostop PVC used for each application generally depends on the following parameters:
• Type of structure
• Amount and type of movements predicted (no movement, axial movement, a combination of axial and transversal movements, etc.)
• Thickness of the cast concrete

Application

Idrostop PVC BI/RI - embedded in the concrete

This type of joint is positioned at half thickness of the foundations or wall and must be stretched and held in position with wire. One end of the wire is attached to the reinforcement rods while the other end is attached to the waterstop using the specific Idrostop PVC Clip fastening clip.

In case of expansion joints, so when Idrostop PVC BI is used, insert a suitable type of compressible material between the first and second cast of concrete to form the joint and and to avoid that this one is clogged by a rigid material.

For expansion joints on vertical walls only, we remind you that the joint must be embedded in the foundation pad to a depth of at least 10 cm.

Idrostop PVC BE/RE - to be secured to the bottom of the formwork

This type of profile is fastened in place by nailing it directly to the formwork or the layer of lean concrete.

The fixing lugs must face towards the next layer of cast concrete so that it forms a perfect bond. In case of expansion joints, to be treated with Idrostop PVC BE, as with embedded joints, insert a suitable type of compressible material between the first and second cast of concrete to form the joint and to avoid that this one is clogged by a rigid material.

In the area immediately around the waterstop, vibrate the concrete so that it is perfectly compacted. When vibrating the concrete, care must be taken to avoid damaging or moving the Idrostop PVC.

Idrostop PVC KK/KR

This type of waterstop is used to waterproof structural joints between existing structures and new buildings.

For the installation of IDROSTOP PVC KK and KR, IDROSTOP RJ-STRIP must be applied on the existing portion of concrete, then the portion of waterstop without stalks must be positioned and mechanically fixed using IDROSTOP KA ALU as a template for anchoring. The waterstop portion with IDROSTOP PVC KK stalks must be embedded in the casting, while the IDROSTOP PVC KR waterstop must be fixed on the cleaning lean.

Place a suitable compressible material between the existing structure and the new concrete casting to create the joint and to prevent it from being blocked by rigid material.

Hot-welding The Ends Of The Joint On Site

The procedure to join the Idrostop PVC and create a perfect bond is by heating the adjacent pieces with a Leister electronic hot air blower. The ends of the parts to be joined must be cut straight and perfectly aligned. Set the Leister to the following temperatures to join the waterstop: +280°C in the bulb area and +320°C for the other areas.
