Application

Bayris Hydrophobic Additive for Concrete and Mortars is designed for all ready-to-use types of concrete and mortar where additional waterproofing is required, particularly in demanding climatic conditions and areas with high groundwater levels. It is used for building foundations, hydraulic concrete, swimming pool shells, retaining walls, water treatment facilities, locks, paving slabs, fences, small concrete products and decorative concrete elements. The Bayris additive is also suitable for open terraces and balconies, concrete drainage and water disposal systems, as well as for preparing surfaces and screeds before fixing tiles and facing stone on exposed horizontal surfaces. Can be added to all cement-based adhesives.

Characteristics

Promotes accelerated self-sealing of concrete pores, reducing water absorption of finished concrete products by two times or more. Prevents efflorescence during service life while maintaining vapour permeability. Improves frost resistance, abrasion resistance and resistance to aggressive environmental conditions. Extends the service life of concrete structures. Enhances the colour intensity of coloured concrete products. Does not cause corrosion of steel reinforcement or cement stone.

Application Instructions

Apply at substrate and ambient temperatures between +5 °C and +30 °C. Add to the concrete mix simultaneously with the mixing water. Ensure even distribution of the additive by thorough mixing.

Consumption

(0.5–0.8) L per 50 kg of cement depending on the mineral composition of the cement, filler characteristics and intended application.

Used for building foundations, hydraulic concrete, swimming pool shells, retaining walls, water treatment facilities, шлюзів, paving slabs, fences, small concrete products and decorative concrete elements.

FAQ
What Is a Hydrophobic Admixture Used For?
  • Provides additional waterproofing protection for concrete and cement mortars, particularly in demanding climatic conditions and areas with high groundwater levels.
  • Suitable for foundations, hydraulic concrete structures, swimming pool shells, terraces, livestock enclosures, drainage systems, screeds, and similar applications.
Where Can a Hydrophobic Admixture Be Used?

The hydrophobic admixture is suitable for:

  • swimming pools;
  • foundations;
  • retaining walls;
  • paving slabs and decorative concrete;
  • balconies, pathways, terraces, and drainage systems.
How Does a Hydrophobic Admixture Work in Concrete?
  • Its action is based on cell-by-cell pore sealing (“self-colmation”) rather than crystal formation.
  • The admixture does not block vapour permeability and does not form a continuous surface film.
How Does It Affect Concrete Strength and Frost Resistance?
  • Forms a chemical barrier within the pores of the concrete, reducing water absorption by half or more without reducing strength and without restricting vapour permeability.
  • Increases frost resistance and abrasion resistance, while helping to prevent reinforcement corrosion and efflorescence.
How Should the Hydrophobic Admixture Be Used?
  • Application temperature range: +5 to +30°C.
  • Add simultaneously with the mixing water and mix thoroughly until a uniform consistency is achieved.
  • Dosage: 0.5–0.8 L per 50 kg of cement. Optimise the dosage based on trial mixes and test samples.
Can I Mix Hydrophobic Admixture with Other Admixtures?
  • Compatible with BAYRIS plasticisers, cement-based adhesives, screeds, and similar products.
  • It is recommended to carry out a trial mix to achieve optimum results.
Can the Effect of the Hydrophobic Admixture Be Enhanced?

Yes, the effectiveness of the hydrophobic admixture can be significantly enhanced by combining it with polypropylene fibres or FIBER-PLUS microfibre by BAYRIS.

Dispersed reinforcement using polypropylene fibres improves the internal structure of concrete, reduces the risk of cracking, and further increases water resistance and frost resistance. The combined use of hydrophobic admixtures and polypropylene fibres is an optimal solution for external applications, foundations, terraces, swimming pools, and underground structures.

Is Additional Waterproofing Required After Use?

The hydrophobic admixture is integrated directly into the concrete, providing permanent waterproofing protection without the need for membranes. However, for complete protection of foundations and underground structures, a comprehensive waterproofing system is recommended.
