Do you have bathroom mold on your ceiling? If you’ve never experienced bathroom mold, perhaps you aren’t looking deep enough into the corners of your bathroom. It’s one of the most common problems in any house; it’s also one of the easiest to prevent. Lack of air, leaky toilets, sinks, and plumbing pipes or damp materials such as rugs, wood, wallpaper, grout, drywall, and fabric are often the reasons for the hassle of mold. And what about drinking water reservoirs? The hygienically pure water has to stay in the interior of the tank without leakage, while outer dirt must be kept 100% outside. These are only two examples why waterproofing is essential.

 

Cementitious waterproofing

One solution that Sika offers is cementitious waterproofing, which has many advantages. Waterproofing mortars make a structure impermeable to liquid water, but allow water vapor to permeate. Plus, they are relatively easy to apply and very cost-effective.

 

Wide application fields

The wide range of potential applications for waterproofing mortars include waterproofing of water tanks, drinking water reservoirs, water channels and basements, as well as waterproofing below the tiling in swimming pools and wet rooms or on balconies. Cementitious waterproofing is suitable for new and refurbishment projects.

 

What is important about waterproofing?

While there are many advantages to these products, what is it that makes a cementitious waterproofing product exceptional? Is it its reliable usage paired with outstanding properties, its broad area of application or its ease of handling?

 

A birthday to celebrate

In this connection, we have a birthday to celebrate. Back in 1981, a product was launched that fulfils precisely these attributes: The cementitious waterproofing mortar SikaTop® Seal-107 was brought to market in Switzerland and has since become a byword for reliability and user-friendliness.

 

Positive or negative-side waterproofing

This two-component, polymer-modified cementitious product is perfectly suited for a wide range of waterproofing applications: keeping water in or out of a structure – whether below the tiling in wet rooms, for tanks and reservoirs, for positive or negative-side waterproofing in basements, or as a protection coating to increase the durability of concrete structures such as bridges or facades.

 

Experience in waterproofing goes back to tunneling

Sika’s vast experience with waterproofing and waterproofing mortars in particular
goes back to the beginning of the 20th century, when the railway tunnels in the Swiss Alps had to be prepared for the electrification of trains. Sika was able to offer the appropriate admixtures for preparing mortars to waterproof the tunnels.

 

Applied in more than 50 countries

This knowledge was used to develop and improve the waterproofing mortar ranges over the years, and in 1981 the first version of SikaTop® Seal-107 was launched in Switzerland. Nowadays, this product is applied all over the world and sold in more than 50 countries. The experience acquired in the course of these years is immense: customer advice and continuous improvement are the basis of this product’s dependability today.

 

Sealing of hairline cracks

SikaTop® Seal-107 is delivered in a two-component kit including the cementitious powder and the polymer dispersion. The polymer improves the waterproofing properties, increases adhesion to the substrate and enhances the crack-bridging characteristics. The product permits the sealing of hairline cracks and reduces permeability to liquid water.

 

Adjustable consistency and excellent workability

A key feature of the product is its adjustable consistency and excellent workability: depending on the customer’s needs and preferences, the product can be applied either by trowel or by brush as a slurry. Additionally, the product
comes delivered ready to use, meaning no additional water needs to be added.

 

Reduction of the ingress of other substances as well

The dense structure of the mortar reduces not only the transmission of free water, but also the ingress of substances such as chlorides or sulfates that can attack the concrete substrate or even the reinforcement bars.

 

Reliably tight waterproof structures

All that remains for us to do is wish SikaTop® Seal-107 Happy Birthday. The millions of people worldwide who have built and are benefiting from tight waterproof structures will doubtless want to add their congratulations too.
