Sika-4A Waterstop 5L

Sika-4A Waterstop 5l is a ready-to-use, quick setting liquid used to stop leaks against high water pressure. Mix with water and ordinary Portland cement to produce a paste and apply to basements, pits, and pools, concrete, rock, and masonry to prevent leakage.

Sika-4a is used as preliminary waterproofing work on wet surfaces or where there is general infiltration of water, prior to the application of subsequent cementitious render or gunite. Typical applications are tunnels and culverts, mine galleries, water reservoirs, concrete pipes and manholes.

It can also be used in quick setting mortar for assembly work, e.g. for fixing anchors, bolts and other fitting subject to early loading in rock or concrete.

The benefits of Sika-4a include, but are not limited to the following:

  • Rapid setting for rapid leak plugging and/or fixing
  • Ready to use, just add clean water and ordinary Portland cement
  • Does not contain chlorides
  • Solvent free
