Sika Top Seal 107 – Cementitious Waterproofing Solution
Waterproofing is an essential part of protecting concrete and masonry structures from water infiltration, dampness, and long-term deterioration. Among the commonly used solutions for construction and repair applications, Sika Top Seal 107 is a two-component, polymer-modified cementitious waterproofing system designed to provide an effective barrier against water penetration. It can be used on a wide range of surfaces and is suitable for both indoor and outdoor applications.
Sika Top Seal 107 combines a liquid acrylic polymer with a cement-based component containing selected aggregates and special admixtures. Once the two components are mixed, they form a cement-grey waterproofing slurry that can be applied to prepared concrete, mortar, masonry, and other suitable substrates. The product is particularly useful for areas such as terraces, roofs, basements, water tanks, sunken slabs, retaining walls, and other structures exposed to moisture.
What Is Sika Top Seal 107?

... coating. The system consists of Part A, a liquid polymer, and Part B, a cement-based powder containing aggregates and additives. The components are supplied in pre-batched quantities, helping provide consistent mixing and application.
One of the key advantages of this system is that no additional water is required during mixing. The components are combined in the specified ratio to produce the required waterproofing slurry. The product is designed to adhere well to properly prepared concrete, mortar, and masonry surfaces. It can also be applied to damp substrates, making it useful for many refurbishment and waterproofing situations where completely dry surfaces may be difficult to achieve.
Major Applications of Sika Top Seal 107
Sika Top Seal 107 is suitable for a variety of residential, commercial, and infrastructure waterproofing requirements. Common applications include:
Waterproofing of roof slabs and flat roofs
Terrace waterproofing
Sunken slab waterproofing
Basement waterproofing
Water tanks and water-retaining structures
Toilets and wet areas
Balconies and sunshades
Retaining walls and sea walls
Waterproofing concrete and masonry surfaces
Treatment of dampness, leaching, and saltpetre action
Repair and plastering applications where a suitable bonding agent is required
The product can be used for both internal and external waterproofing and is designed to reduce water penetration into concrete and masonry. Sika's product information also identifies applications involving protection of concrete against carbonation and chloride penetration.
Key Benefits
One of the reasons cementitious waterproofing systems are popular in construction is their relatively straightforward application. Sika Top Seal 107 offers several features that make it suitable for waterproofing and refurbishment projects.
Easy application: The mixed material can be applied using suitable brushes, a squeegee, spray equipment, or a flat trowel, depending on the application and desired consistency.
Strong adhesion: When applied to sound and properly prepared substrates, the coating provides good adhesion to concrete, mortar, and masonry.
Water resistance: The coating helps prevent water infiltration and improves the watertightness of treated surfaces.
Flexible waterproofing layer: The system has some flexibility and can help bridge minor hairline cracks in suitable, non-moving surfaces. It should not, however, be considered a solution for active structural movement or significant cracks.
Suitable for damp substrates: Properly prepared damp surfaces can be coated, which can be advantageous during renovation and repair work.
Protection of concrete: The system helps protect concrete against water penetration and can provide protection against carbonation and chloride penetration.
Potable-water applications: The current Sika India product information states that the product is approved for potable-water contact, subject to the applicable system requirements and project specifications.
Why Choose Sika Top Seal 107 for Waterproofing?
Choosing the right waterproofing material depends on the substrate, water exposure, application area, and project requirements. Sika Top Seal 107 provides a practical cementitious waterproofing option for concrete and masonry because it combines polymer modification with cement-based waterproofing technology.
Its pre-batched components, relatively simple mixing process, good adhesion, water resistance, and suitability for a range of construction applications make it useful for both new construction and refurbishment work. It is particularly valuable in areas where protection against moisture and water ingress is required without relying on a complex multi-product system.
For best results, however, waterproofing should not be treated as simply applying a coating. Proper substrate preparation, detailing around joints and pipe penetrations, correct mixing, appropriate coating thickness, curing, and protection of the finished system are all important.
