Methods and Solutions for Making Concrete Waterproof

Concrete is a durable and versatile material, but by its nature it is porous and prone to water absorption. Without proper waterproofing, moisture and weathering can cause structural damage, compromising its durability. In this article we will explore the best techniques for making concrete waterproof, with a focus on the innovative solutions offered by DRYKOS.

Why waterproof concrete?

Water can seep into concrete through pores and micro-cracks, causing:

  • Deterioration of the structure due to freeze-thaw cycles.
  • Corrosion of internal metal reinforcement, reducing mechanical strength.
  • Mold and moisture formation, with aesthetic and hygienic consequences.
  • Reduction in the overall durability of the work.

To prevent these problems, it is essential to adopt an effective waterproofing system.

Methods to make concrete waterproof

There are different techniques for waterproofing concrete, depending on the needs and type of structure.

1. Crystallizing additives: protection from within.

One of the most innovative methods is the use of crystallizing admixtures, such as DRYMIX ULTRA from DRYKOS. These products are added to fresh concrete or applied to the surface and penetrate capillaries, reacting with moisture to form insoluble crystals that permanently seal porosity.

  • Active and permanent waterproofing.
  • Self-contained sealing of microcracks up to 0.4 mm.
  • Protection against aggressive chemicals 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, pavements and roofs exposed to the elements.

  • Effective against direct infiltration.
  • Available in different formulations for specific needs.
  • Easy to apply to existing surfaces.

3. Waterproofing membranes: structural protection

Bituminous or synthetic membranes are another alternative for waterproofing horizontal or vertical surfaces. They can be cold or hot applied and offer effective protection, but require careful installation to avoid weak spots.

  • Ideal for foundations, roofs and terraces.
  • Good mechanical and weathering resistance.
  • They require periodic maintenance.

Which solution to choose?

The choice of waterproofing system depends on the type of structure and exposure to water. For effective and long-lasting waterproofing, crystallizing admixtures such as DRYMIX ULTRA offer the best protection built into the concrete, without the need for future work or frequent maintenance.
