Methods and Solutions to Waterproof Concrete
Concrete is a strong and versatile material, but by its nature, it is porous and subject to water absorption.
Without adequate waterproofing, humidity and atmospheric agents can cause structural damage, compromising its durability over time. In this article, we will explore the best techniques for making concrete waterproof, with particular attention to the solutions offered by DRYKOS.

Why Waterproof Concrete?
Water can penetrate concrete through pores and micro-cracks, causing:
- Deterioration of the structure due to freeze-thaw cycles.
- Corrosion of internal metal reinforcements, reducing mechanical strength.
- Formation of mold and humidity, with aesthetic and hygienic consequences.
- Reduction of the overall durability of the structure.
To prevent these problems, it is essential to adopt an effective waterproofing system.
Methods to Waterproof Concrete
Various techniques exist for waterproofing concrete, depending on the requirements and type of structure.
1. Crystalline Admixtures: Protection from Within
One of the most innovative methods is the use of crystalline admixtures, such as DRYMIX ULTRA by DRYKOS. These products are added to fresh concrete or applied to the surface, penetrating the capillaries and reacting with moisture to form insoluble crystals that permanently seal the pores.
- Active and permanent waterproofing.
- Self-sealing of micro-cracks up to 0.4 mm.
- Protection against aggressive chemical agents such as chlorides and sulfates.
- Increased durability of the structure.
2. Waterproofing Coatings: Surface Protection
Another solution is the application of waterproofing coatings, such as polyurethane, epoxy, or cementitious resins, which create a protective barrier on the concrete surface. This method is ideal for terraces, paving, and roofing exposed to atmospheric agents.
- Effective against direct infiltration.
- Available in various formulations for specific needs.
- Easy to apply on existing surfaces.
3. Waterproofing Membranes: Structural Protection
Bituminous or synthetic membranes represent a further alternative for waterproofing horizontal or vertical surfaces. They can be applied cold or hot and offer effective protection, but require careful installation to avoid weak points.
- Ideal for foundations, roofs, and terraces.
- Good mechanical and weather resistance.
- Require periodic maintenance.
Which solution to choose?
The choice of waterproofing system depends on the type of structure and its exposure to water.
For effective and lasting waterproofing, crystallizing admixtures like DRYMIX ULTRA offer the best integrated protection in the concrete, without the need for future interventions or frequent maintenance.
Conclusion
Making concrete waterproof is essential to ensure the longevity and safety of structures. With DRYKOS' advanced technologies, such as DRYMIX ULTRA crystalline admixtures, permanent and reliable waterproofing can be achieved.
