Materials used in the project for the construction of the underground parking:

• WPM® Metal Sheet Waterstop 80R / 125R: To waterproof construction joints up to 2.4 bar positive water pressure.
  
• WPM® Crack Inducing Waterstop: For controlling and waterproofing concrete shrinkage cracks
  
• WPM® Formwork Waterstop: Used for various technological reasons to ensure a watertight connection in the construction joint.
• Concrete volume with admixture: Gives concrete "self-healing" ability for cracks up to 0.4 mm.
