Waterproofing is the basis of the construction industry and the safe use of any property. Without it, foundations, walls or floors quickly deteriorate, and interiors can become a breeding ground for mold. Properly selected materials, careful execution of vertical and horizontal insulation and knowledge of various types of protection allow to avoid costly repairs, protect the foundations, prevent moisture penetration (and the harmful effects of water) and, consequently, provide peace of mind for years.
The most important properties of waterproofing
When choosing waterproofing, first of all, attention should be paid to its durability. After all, it should remain tight even on uneven substrate, be resistant to difficult conditions, variable temperatures and work with other layers, e.g. thermal insulation. Investment in proven materials – bituminous emulsions, films, elastomeric membranes or polymer membranes – will certainly pay off.
Types of waterproofing and their application
The method of protection against moisture should be adapted to specific conditions. Different solutions will work for foundations that come into direct contact with damp soil, and others in bathrooms or on terraces. The choice of the right type of waterproofing is influenced by the analysis of the building’s location, the type of substrate, the level of groundwater and the moisture load.
Damp proofing
Damp proofing is the so-called light waterproofing, used in permeable soils without np hydrostatic pressure. It is often used, for example, to protect foundations on sands. This type of waterproofing includes asphalt films and emulsions on foundation walls that protect the house from moisture penetrating into the walls of higher floors.
Waterproofing
Waterproofing (moderate or severe) is applicable where the soil has poor water drainage or the groundwater level is high. In such situations, torch-on membranes, rubber-bitumen membranes, bentonite or two-component compounds are used. This type of protection is worth using, for example, in basements located in clayey soils, exposed to long-term presence of water.
Where is waterproofing necessary?
Not every part of the building is equally at risk of moisture contamination. There are places that almost daily have contact with water or moisture – both outside and inside the building. Knowing the specifics of these places and potential threats allows for better adaptation of insulation methods and materials. For example, if we put polystyrene waterproofing on an unprotected substrate, problems with moisture penetration may occur higher up.
Bathrooms and kitchens
These are rooms exposed to flooding, splashing and regular high humidity. It is worth using materials that protect the substrate under the tiles – liquid films, sealing tapes, etc. Thanks to them, surfaces remain dry and water does not penetrate deep into the structure, preventing the formation of mold and damage to the cladding.
Foundations and basement waterproofing
Underground parts of the building are exposed to moisture throughout the year. Proper vertical and horizontal insulation of foundations and basement walls prevents water from being drawn up, the growth of fungi and the cracking of plasters. The use of waterproofing felts, membranes or bituminous compounds creates a tight barrier against the onslaught of moisture.
What is important – they should also be used in the case of the so-called “white bathtub” technology which is based on the use of watertight concrete.
Balconies, terraces and external stairs
External elements are exposed to rain, snow, frost and UV radiation. Waterproofing in these places must be flexible and resistant to weather changes. Liquid films, bituminous-polymer compounds or membranes applied under ceramic cladding are an effective way to avoid leaks, cracks and further damage.

How to choose the right waterproofing?
It is best to make a decision after analysis of soil and water conditions, the building’s intended use and the degree of exposure to moisture. On permeable soils, light waterproofing is sufficient, while on difficult, clayey areas, heavy, heavy waterproofing is required. In bathrooms, liquid films are ideal, while in basements, two-component compounds are recommended. It is worth consulting a specialist who will take into account the specifics of the building.
Effective waterproofing requires not only the selection of appropriate materials, but also the use of proper techniques. Attention to detail at every stage of the work allows you to avoid costly repairs in the future. To properly protect a building from moisture, it is worth following the tips below.
- Invest in quality – good quality materials guarantee durability and effectiveness.
- Follow the manufacturer’s recommendations – each waterproofing requires proper preparation and application.
- Choose system solutions – sealing tapes and liquid films provide comprehensive protection.
- Regularly check the condition of the waterproofing – minor repairs can prevent more serious damage.
- Remember that insulation should only be applied after the technological moisture has dried on the walls.

Waterproofing in practice. Summary
Waterproofing is an investment in the durability and longevity of the building. Properly selected and professionally executed, it protects against dampness, mold and costly renovations. Therefore, the use of
waterproofing and maintenance of roofing is so important, and a well-thought-out selection of materials – from simple films to advanced membranes – ensures savings in time and money.
