Concrete Waterproofing Watertight Concrete Concrete Admixture

Waterproof concrete is an impermeable concrete used for long-lasting, durable watertight construction. To improve the impermeability of the concrete, water-resisting admixtures can be added. Nevertheless, design and construction of a watertight concrete structure is a system approach, and waterproof concrete is only one element of it. Water impermeability is determined by fulfilling requirements to limit water permeability through the concrete itself, the joints, installation parts and cracks.

Key Advantages of Sika? Watertight Concrete System

  • Time saved at design and construction stages, as the need for complex detailing and installation is eliminated
  • Cost effective in comparison with other systems
  • Delivers maximum usable area to the occupier
  • Peace of mind for the owner, designer, contractor, and end user of the building
