WALLZIP Used at the Southern Bypass of Warsaw Construction Site

The southern Warsaw bypass (S2) is the road which is being built from Puławska hub to Lubelska hub. The road will be 18.5 km long and will be commissioned in H2 2020.

The investment was divided into three stages.

Stage A: from Puławska hub to Przyczółkowska hub, 4.6 km;

Stage B: from Przyczółkowska hub to Wał Miedzeszyński hub, 6.5 km;

Stage C: from Wał Miedzeszyński hub to Lubelska hub, 7.5 km. The contractor of the last stage is Warbud S.A. copartnership, which once again used TLC’s WALLZIP diaphragm wall system. The system advantages were also recognized by other company’s clients.

• Ergonomic seal groove prevents from sliding out the seal,
• Possibility of creating second seal groove if required,
• The first and middle elements are made of 25mm thick highly wear-resistant steel sheet,
• The strapping end is cut at 40 degrees angle which allows for easy placement at the bottom of the excavation,
