Waterproofing is an important stage in protecting buildings and structural surfaces. A properly selected waterproofing system helps protect a surface from water, moisture, and environmental exposure.
The same product is not suitable for every project. A roof, swimming pool, floor, basement, and concrete structure operate under different conditions. Several important factors should therefore be considered before selecting a waterproofing product.
1. Identify the Surface Type
First, determine the type of surface on which the work will be performed.
This may include:
- Concrete;
- Cement screed;
- Ceramic surfaces;
- Metal;
- Brick or blockwork;
- An existing waterproofing layer.
Check the product’s technical information to confirm that it is suitable for the intended surface.
Some applications may require preliminary cleaning, repair of damaged areas, or the use of an appropriate primer.
2. Consider the Type of Water Exposure
Different areas are exposed to different levels and forms of water and moisture.
- A roof is exposed to rain, sunlight, and temperature changes;
- A swimming pool remains in continuous contact with water;
- Bathroom and wet-area floors experience periodic water exposure;
- Basements and foundations may be affected by groundwater and soil moisture.
The selected product must be suitable for the specific application environment and the intensity of water exposure.
3. Evaluate Movement and Cracking Risks
Some surfaces expand, contract, or develop cracks because of temperature changes, structural movement, or applied loads.
In such cases, a flexible waterproofing material may be required to accommodate limited movement and cracking.
Corners, joints, pipe penetrations, and other complex areas may also require:
- A flexible waterproofing coating;
- Self-adhesive insulation tape;
- Joint sealant;
- A polyurethane or polyurea system;
- A cement-based waterproofing material.
4. Select the Product According to the Application
Roofs and External Terraces
Products used on roofs and exposed terraces must be suitable for outdoor conditions.
Pay particular attention to:
- Temperature changes;
- Sun exposure;
- Rain and other precipitation;
- The possibility of standing water;
- The flexibility of the coating.
Swimming Pools and Water Tanks
Products used for swimming pools and reservoirs must be suitable for continuous contact with water.
It is also important to consider:
- Correct surface preparation;
- Treatment of corners and joints;
- Compatibility with the final finishing material;
- Compliance with application instructions;
- The required drying and curing time.
Floors and Wet Areas
In bathrooms, kitchens, balconies, and other wet areas, waterproofing is commonly installed beneath the finishing material.
Pay particular attention to:
- Wall-to-floor junctions;
- Pipe penetrations;
- Areas surrounding drainage systems;
- Corners and movement joints.
5. Review the Technical Information
A product should not be selected only according to its name, image, or price.
When selecting a product, review:
- Its intended application;
- Surface compatibility;
- Product consumption;
- The recommended number of layers;
- The recommended layer thickness;
- Drying and curing time;
- Application temperature;
- Package size;
- The technical data sheet;
- The manufacturer’s application instructions.
6. Examples from Our Product Catalogue

Each product is intended for a particular purpose. The final choice should be based on the product’s technical documentation and the actual conditions of the project.
7. Follow the Application Instructions
Even a high-quality product may not achieve the desired result when the surface is improperly prepared or the application instructions are not followed.
Before starting work, it is important to:
- Clean the surface thoroughly;
- Repair damaged areas;
- Treat cracks and joints;
- Apply the required primer;
- Follow the recommended layer thickness;
- Allow sufficient drying and curing time.
For larger or more complex projects, the product choice and application method should be reviewed with a specialist.
Conclusion
Choosing the correct waterproofing product begins with an assessment of the working surface and environmental conditions, rather than only the product’s price or brand.
Before making a decision, determine:
- Where the product will be used;
- What type of surface will be treated;
- How severe the water exposure will be;
- Whether a flexible system is required;
- Which supporting materials will be needed.
