Concrete impregnation is a treatment where a protective liquid is applied to the concrete surface. This liquid penetrates deeply into the concrete and creates an invisible barrier that repels water, chemicals, and other harmful substances. This process differs from other treatments, where concrete coating and sealers form the protective layer on the surface.
The technique is applied in the following situations, among others:
- In commercial construction, for protecting parking garages against oil, fuel, and wear from vehicles.
- In infrastructure for protecting bridges and viaducts against corrosion and weather influences.
- For private homes and commercial buildings where aesthetics and protection of structural elements are improved.
Impregnation in 3 Phases
The impregnation of concrete involves several phases that must be carefully executed to achieve optimal results. These phases typically look as follows:
- Surface preparation: the concrete surface must be thoroughly cleaned to remove dirt, dust, and any old coatings. This allows the impregnating agent to penetrate effectively.
- Application of the impregnating agent: the impregnating agent is sprayed or rolled evenly onto the surface. The liquid penetrates the concrete and forms a protective layer inside the material.
- Curing and post-treatment: after application, the impregnating agent must be given time to fully penetrate and cure. This depends on the product used and the ambient temperature.
The chemical action of impregnating agents is based on a reaction with the porous structure of concrete, creating a hydrophobic effect that repels liquids.
