Proper waterproofing is crucial for protecting the property from water damage. Water intrusion can lead to structural issues, costly repairs, and even health hazards like mold and mildew growth. Wet area like bathroom, toilet and kitchen, semi-exposed area like balcony and air-cond ledge, need effective waterproofing solutions.
Wet Area That Need Waterproofing
Indoor Wet Area
- Toilet
- Shower area / Bathroom
- Changing room
- Ablution
- Kitchen
- Pantry
Semi Exposed Wet Area
- Balcony
- Verandah
- Yard
- Air-conditioner ledge
The above are just some examples, and wet areas can vary depending on the design and the purpose of the building or area. It is important to identify all the potential wet areas in a building and implement appropriate waterproofing solutions to prevent water damage and avoid costly repairs in the future.

FAQ
Cementitious waterproofing mortar is a ready-mixed waterproofing compound used to protect structures against water infiltration. They are supplied as ready-to-use solutions either in one single component or two-component packs to seal against damp soil, seepage and percolating water. In addition, cementitious waterproofing mortar can also be used for the protection of concrete structures. Waterproofing mortars are often applied in water reservoirs, water retaining structures, basements, and other engineering structures as well as beneath tiling for swimming pools, balconies, bathrooms, and kitchens.
In general, any cementitious based mortar and liquid applied bituminous coating are suitable be used for these areas.
Sika recommends a consumption rate of 1.0 kg per m² per coat and a minimum of two coats are required for bathroom, toilets, and kitchen.
Typical bond strength of cementitious waterproofing mortar ranges from 0.5–1.0 N/mm², depending on the type and grade of the products.
An angle fillet is incorporated at the base angle to round off the 90° right angle at the wall to floor joint to form a 45° angle. A typical angle fillet is formed using cementitious based material. Thus, it is hard and non-deformable. An edge tape is a thermoplastic elastomer (TPE) that is elastic in nature. The edge tape is an elastic system component that is used in combination with Sika waterproofing mortar to form a high elastic and crack bridging sealing tape around the edge and corners. Cement sand with latex (or SikaGrout®) angle-fillet is sufficient when a concrete kicker is provided. An edge tape is recommended for drywall or precast systems and also when a concrete kicker is not provided.
