Sika®-1 S Plus


Sika®-1 S Plus is a 2 component waterproofing admixture for mortar and concrete.  It is a special mix of pore-blocking hydrophobic admixture and chemicals that can form crystalline structures within the pores and capillary tracts of the concrete. It effectively waterproofs the concrete against groundwater penetration from any direction, protecting against waterborne salts and eliminating concrete decay.

Sika®-1 S Plus has the following properties:
  • Very low water absorption providing watertightness and increased durability
  • Chloride free
  • Ammonia free
  • Compatible with other Sika admixtures
  • Compatible with most finishes
