This layout groups the uses by application type, making it easy for engineers and contractors to scan.

General Waterproofing & Damp-proofing

• Interior and exterior waterproofing of concrete, cementitious rendering, brickwork, and blockwork.

• Rigid waterproofing of basement walls (new construction and refurbishment).

• Sealing internal basement walls against dampness.

Water Retaining Structures & Wet Areas

• Waterproofing systems for swimming pools, wet rooms, and water tanks.

• Approved for use with potable (drinking) water containment.

Concrete Protection & Repair

• Protection against de-icing salts and freeze-thaw cycles.

• Sealing fine “hairline” cracks in concrete structures (not subject to movement).

• Pore/blowhole filling and leveling mortar for concrete repair works.

Product Profile: SikaTop® Seal-107 IN

Two-Part Polymer-Modified Cementitious Waterproofing Slurry

Product Description

SikaTop® Seal-107 IN is a two-part, polymer-modified cementitious waterproofing mortar slurry comprising a liquid polymer and a cement-based mix with special admixtures. It is designed to prevent water infiltration across a wide range of concrete and masonry structures.

Key Features & Benefits

• Superior Waterproofing: Effectively seals against water penetration under pressure.

• Potable Water Safe: Non-toxic and suitable for use in drinking water tanks and reservoirs.

• Crack Bridging: Semi-flexible properties allow it to accommodate fine “hairline” cracks in concrete.

• High Adhesion: Bonds excellently to damp substrates without requiring a primer.

• Dual Application: Versatile consistency allows application as a slurry (brush) or mortar (trowel).

• Durability: Resistant to freeze-thaw cycles, carbonation, and chloride ingress.

• Non-Corrosive: Safe for use in contact with steel and iron reinforcements.

• User Friendly: Pre-batched components ensure consistent quality and easy mixing.

Main Areas of Application

SikaTop® Seal-107 IN is versatile and suitable for both interior and exterior use in new construction and refurbishment projects:

Water Retaining Structures:

• Swimming pools, fountains, and water features.

• RCC gutters, drains, and planter boxes.

Structural Waterproofing:

• Basement walls (internal and external) and retaining walls.

• Lift pits and sump areas.

• Protection of concrete against de-icing salts and freeze-thaw attacks.

Wet Areas & Surfaces:

• Bathrooms, kitchens, and washrooms.

• Balconies, terraces, and flat roofs.

Repair & Finishing:

• Sealing fine hairline cracks in static concrete structures.

• Pore/blowhole filling.

• Leveling mortar for concrete repair works.
