Sika Waterbar: Advanced Sealing Solutions for Concrete Joints

Technical Overview: Sika Waterbar is a high performance PVC "Polyvinyl Chloride" waterstop designed by Sika to secure construction and expansion joints.

These profiles are typically supplied in rolls of 30 linear meters, with widths ranging from 20 cm to 30 cm, engineered to provide a flexible yet impenetrable barrier against pressurized water.

Core Objective & Efficiency

The primary function of the Sika Waterbar is to eliminate potential leakage paths at structural joints.

It is an essential and highly effective component in hydraulic structures and infrastructure projects, where the integrity of concrete water retaining elements is paramount.

The Engineering Logic of Waterstops

The efficiency of the Sika Waterbar lies in its multi ribbed design.

These ribs "fins" create a sophisticated interlocking mechanism with the concrete matrix. By embedding these ribs into the concrete, any attempting water ingress is forced into an extremely tortuous and complex path, effectively neutralizing the hydrostatic pressure and preventing seepage.

Strategic Applications & Installation

Sika Waterbars are indispensable for any joint within the floors or walls of water tanks and swimming pools:

• Foundation & Wall Integration: During the casting of reinforced concrete for water tank floors, approximately 12 cm of the waterbar is embedded within the floor slab near the wall perimeter, secured firmly with stirrups.

• The remaining portion remains upright to be integrated into the wall during the subsequent concrete pour.

• Sequential Casting: It is also utilized when walls are cast in multiple stages, acting as a bridge between the previous and subsequent concrete pours to ensure a watertight transition.
