SikaTop Seal 107 is a two-component, polymer-modified, cementitious waterproofing and protective slurry mortar for concrete.


It is slightly flexible to tolerate fine cracks and suitable in both interior and exterior applications.


SikaTop Seal 107 provides the following beneficial properties:

  • Improves the watertightness of water-containing concrete tanks, reservoirs, and clearwells.
  • Protects against water penetration, yet water vapor permeable (breathable).
  • Excellent freeze/thaw resistance.
  • Good adhesion to sound, prepared substrates.
  • Easy and fast mixing and application.
  • Good abrasion resistance.
  • Protects against concrete carbonation (80 mils SikaTop® Seal 107 is equivalent to 6 inches of concrete).
  • Can be mixed to slurry or trowelable consistency.
  • Improves concrete/masonry appearance.
  • Available in concrete gray and off-white.
  • Approved for potable water contact.

Where to use

  • Horizontal surfaces subjected to light foot traffic (balconies).
  • For waterproofing of drinking water, tanks, reservoirs, and clear wells.
  • For internal and external waterproofing and damp-proofing concrete, mortar blockwork and brickwork.
  • For protection of concrete structures against the deleterious effects of deicing salts and freeze/thaw cycles.
  • For sealing “hairline” cracks in concrete structures not subject to movement surfaces.
  • For interior and exterior waterproofing of basements.
  • Vertical surfaces. 


  • For damp-proofing: apply one coat at 40 mils.
  • For waterproofing: apply two coats at 40 mils per coat. Theoretical thickness (wet film) on smooth substrates: 40 ft.2 /gal. = 40 mils (2 kg./m2 = 1 mm). The above figures are theoretical and do not allow for substrate profile and wastage. Three coats may be required in areas of extremely high water infiltration. Packaging 44 lb. unit - when mixed yields 2.65 gallons (10 l) Component ‘A’ - 1 gal. plastic jug; 4/carton. Component ‘B’ - 35.5 lb. multi-wall bag.
Typical Clean Water Tank Problems
Inside the tank:
  • Surface Erosion
  • Water Seepage
  • Porous Surfaces
  • Difficult to Clean
  • Poor Appearance
  • Leaching
Outside the tank:
  • Ground Water Infiltration and Seepage
  • Efflorescence sPorous Surfaces
  • Poor Appearance
  • Chloride Ingress
  • CO2 Ingress
SikaTop Seal 107
  • Seals and protects porous concrete surfaces sProduces a watertight concrete surface
  • Tolerates fine cracks in concrete substrate
  • Produces a dense, easy-to-clean surface
  • Stops water seepage
  • Fills concrete pores and levels all surface irregularities sResists water, chloride,
  •  CO2 ingress and extends the service life of the water tank…
