Preshaped trapezoidal steel mesh cage for CLAYSEAL 25.20

Code: PRS.0139

Components: 1

Appearance: Steel mesh

Trapezoid preshaped steel square mesh cage open only on one side, to be used to encourage correct positioning of the CLAYSEAL 25.20 sodium bentonite waterstops, and to prevent the displacement from the seat provided, especially in complex situations or on surfaces which are not perfectly prepared. Once the joint is inserted, BENTONET will have to be fixed to the concrete support using steel nails and washers every 20-25 cm.

Use fields

Rigid construction joints (non-expanding) and connections with safe and permanent hydraulic seal.

Preparation of supports

Prepare the smoothest and most planar laying surface, using REPAR TIX to compensate for any inhomogeneity, and accurately remove crumbling, non-adhering, powdery parts.

Use method

Spread the sodium bentonite waterstop CLAYSEAL 25.20 in the designated position. Install the BENTONET joint locking cage above the CLAYSEAL 25.20 hydro-expansive kerb. Fix it to the support by nailing: a steel nail every 20-25 cm approximately. The joints between the waterstop kerbs are sealed by simply flanking them by at least 10 cm and not by overlapping the ends.
The positioning of the CLAYSEAL 25.20 hydro-expansive kerb must ensure a concrete covering of 10-12 cm in order to contain the expansive action caused by hydration.
