Waterproofing and waterproofing tape: How to protect your home from moisture

Waterproofing and Waterproofing Tape: How to Protect Your Home from Moisture

Moisture is one of the primary enemies of any building structure. It gradually destroys concrete, brick, and plaster, and provokes the appearance of mold and cracks. Waterproofing solves this problem: it creates a continuous seamless coating that does not allow water to pass through regardless of its source — whether it is splashes in a shower, atmospheric precipitation on a terrace, or groundwater near the foundation.

In this article, we will examine the main types of waterproofing materials, their technical characteristics, and the rules for choosing them for a specific task. Waterproofing materials are divided into several main types depending on the principle of action and method of application: film (roll and membrane), coating (mastics), injection, and penetrating. Each of these options has its own application features, advantages, and limitations. In this article, we will focus specifically on coating waterproofing materials as one of the most convenient and common solutions in private and professional construction.

Some Options for Coating Waterproofing

All coating waterproofings are divided into several types depending on their composition and scope of application.

Acrylic Water-Dispersion Mastics

The most common option for interior work. The base consists of an acrylic copolymer dispersion. After drying, an elastic rough film is formed, which does not allow water to pass through and simultaneously ensures good adhesion of tile adhesive. Such mastics are non-toxic, odorless, and are diluted with water. They are suitable for bathrooms, showers, restrooms, and kitchens under tile cladding. Materials such as Aquastop Hydro and Grover MW 301 belong to this group.

Two-Component Waterproofing

This is a separate class of materials with increased reliability. Unlike one-component ones, these mastics contain a second active component — powdered modified cement, which is mixed with a liquid acrylic base immediately before application. Due to this, the finished coating acquires significantly higher strength and wear resistance: it is capable of withstanding constant hydrostatic water pressure acting not only on the bottom but also on the walls of the structure (for example, in swimming pools or reservoirs). This is why two-component waterproofing is the optimal solution for objects where water influences continuously and under pressure.

In our assortment, this class is represented by the material Eskaro Aquastop Hydro 2K. It consists of a liquid acrylic component A and a powder component B, which are mixed in a 1:3 ratio by weight. The ready solution must be used within 60 minutes. The coating withstands water pressure up to 0.7 MPa, is resistant to chlorinated water and ultraviolet light, and does not cause steel corrosion. It withstands substrate cracking up to 2.5 mm at temperatures down to −20 °C.

It is used for swimming pools, drinking water reservoirs, fountains, artificial ponds, exterior walls of basements and foundations, balconies, and terraces. Tiles can be glued as early as 24 hours after applying the last layer.

Bitumen-Rubber Mastics

These are materials based on modified bitumen intended primarily for outdoor work. They are resistant to atmospheric influences and temperature fluctuations and provide reliable seamless waterproofing on complex surfaces. Depending on the composition, such mastics can be SBS-modified (with increased elasticity) or with the addition of synthetic polymers that improve the adhesion and durability of the coating.

Two products of this group are presented in our assortment. Grover Dysperbit DB+ is a water-dispersion SBS-modified mastic for flat roofs and seamless roof coatings. The material is applied to wet surfaces and becomes resistant to precipitation in just 5 hours. It withstands substrate cracking up to 1 mm at a temperature of −25 °C and does not melt even at a temperature of +100 °C. It is used for seamless roof coatings with fiberglass reinforcement and for the restoration of old roll coverings. The second product — Grover Dysperbit — is designed specifically for the waterproofing of the plinth and underground parts of buildings where protection from groundwater and capillary moisture is required. Inside residential premises with the constant presence of people, materials of this group are not used.

Why Reinforcing Tape is Needed for Waterproofing

Reinforcing tape is an obligatory part of any correctly executed waterproofing. It is embedded into a fresh layer of mastic and strengthens the most vulnerable places: internal corners, seams between slabs, joints of surfaces made of different materials, zones around plumbing fixtures, and floor drains. Without tape, even high-quality mastic in corners eventually becomes covered with micro-cracks due to thermal deformations of the structure.

In our assortment, the Eskaro Hydro Tape line is presented in several versions. Standard reinforcing tape in rolls of 25 meters is intended for corners and joints under ordinary coating waterproofing. Hydro Tape 2K waterproofing tape is available in rolls of 10 and 50 meters. It was developed specifically for use with two-component materials to protect critical connection nodes.

The installation technology for the tape is the same for all versions: the tape is laid into a fresh layer of mastic and pressed firmly with a plastic or rubber spatula so that it is completely saturated with the material. After drying, an additional layer of waterproofing is applied on top. The tape is always embedded in two layers of mastic — this is a mandatory condition for a reliable connection.

How to Choose the Required Material

The choice depends on the specific task.

Bathroom, shower, toilet, kitchen — under tile

Any of the acrylic mastics will work: Aquastop Hydro or Grover MW 301. Be sure to use Eskaro Hydro Tape reinforcing tape in corners, seams, and around drains. For non-standard or highly absorbent substrates (drywall, aerated concrete), apply Eskaro Aquastop Hydro Primer or Aquastop Strong adhesion primer before the mastic. You can see what the complete process of waterproofing a bathroom looks like in practice in the video "Waterproofing a Bathroom with Eskaro Aquastop Hydro".

Swimming pool, fountain, water reservoir, foundation against groundwater

Exclusively Aquastop Hydro 2K. This is the only material in this category capable of withstanding constant water pressure and external loads. Use it together with Eskaro Hydro Tape 2K in connection nodes. For non-standard or highly absorbent substrates, apply Eskaro Aquastop Hydro Primer or Aquastop Strong primer beforehand.

Flat roof, restoration of old coating

Grover Dysperbit DB+. It is applied with fiberglass reinforcement in two layers. If the substrate is prone to the appearance of mold or algae, additionally treat it with Biotol biocidal agent before applying the mastic.

Plinth, underground parts of the building

Grover Dysperbit — for protection against groundwater and capillary moisture. If biological contamination of the surface is present, treatment with Biotol is recommended before application.

Conclusion

Waterproofing is not the stage of renovation where it is worth saving money or rushing. An error in material choice or a violation of application technology does not manifest itself immediately: water finds a path gradually, and when the problem becomes obvious, it is no longer possible to eliminate it without dismantling the base.

The main thing to remember: acrylic mastics handle bathrooms and kitchens perfectly but are not intended for swimming pools and basements. For a serious water load — only two-component Aquastop Hydro 2K. For the roof — bitumen-rubber Dysperbit DB+. For the plinth — Dysperbit. And in each of these cases, reinforcing tape in corners and seams is a mandatory, not a desirable, detail.

If the material is selected correctly, the substrate is prepared according to the instructions, and the reinforcement of the nodes is not neglected — the waterproofing system will last as long as the cladding itself, without leaks. With Eskaro waterproofing materials, you create a reliable barrier against moisture.

Use it together with Eskaro Hydro Tape 2K in connection nodes. For non-standard or highly absorbent substrates, apply Eskaro Aquastop Hydro Primer or Aquastop Strong primer beforehand.

Flat roof, restoration of old coating

Grover Dysperbit DB+. It is applied with fiberglass reinforcement in two layers. If the substrate is prone to the appearance of mold or algae, additionally treat it with Biotol biocidal agent before applying the mastic.

Plinth, underground parts of the building

Grover Dysperbit — for protection against groundwater and capillary moisture. If biological contamination of the surface is present, treatment with Biotol is recommended before application.

Conclusion

Waterproofing is not the stage of renovation where it is worth saving money or rushing. An error in material choice or a violation of application technology does not manifest itself immediately: water finds a path gradually, and when the problem becomes obvious, it is no longer possible to eliminate it without dismantling the base.

The main thing to remember: acrylic mastics handle bathrooms and kitchens perfectly but are not intended for swimming pools and basements. For a serious water load — only two-component Aquastop Hydro 2K. For the roof — bitumen-rubber Dysperbit DB+. For the plinth — Dysperbit. And in each of these cases, reinforcing tape in corners and seams is a mandatory, not a desirable, detail.

If the material is selected correctly, the substrate is prepared according to the instructions, and the reinforcement of the nodes is not neglected — the waterproofing system will last as long as the cladding itself, without leaks. With Eskaro waterproofing materials, you create a reliable barrier against moisture.
