1. International Practice
Silane impregnation technology is globally recognized for enhancing concrete durability. Unlike surface coatings, silane molecules react chemically with the concrete’s pore walls, forming a hydrophobic layer inside the matrix. This invisible protection prevents water and chloride penetration while maintaining vapor permeability. As a result, structures treated with silane sealers remain dry, corrosion-free, and serviceable for decades — a standard method for bridge decks, coastal piers, and tunnel linings.

2. Application Challenges
Concrete exposed to rain, deicing salts, and marine environments faces progressive deterioration. Traditional surface coatings can peel, trap moisture, and require frequent reapplication. Durable protection demands:

• Deep penetration even in dense, aged concrete;

• Resistance to UV exposure, traffic wear, and alkaline environments;

• Permeability to vapor but impermeability to liquid water;

• Long service life with simple on-site application.
  ZRETE’s silane systems meet these demands with optimized molecular weight and purity for deeper absorption and longer-lasting hydrophobicity.

3. Product Performance
ZRETE’s T80 and T99 silane impregnating agents are reactive organosilane sealers designed to ensure enduring waterproofing and chloride resistance:

• High Active Content (≥80–99%) — ensures penetration depth up to 8 mm into concrete pores.

• Water Repellency ≥90% — minimizes water absorption and chloride ingress.

• Breathable, Non-Film-Forming Protection — preserves natural surface appearance and prevents blistering.

• UV & Chemical Resistance — stable against sunlight, alkali, and freeze–thaw cycles.

• Long-Term Durability — over 10 years of maintenance-free performance in exposed environments.
  Easy to apply by roller, brush, or spray, ZRETE silane systems are suitable for bridges, coastal structures, tunnels, and industrial floors requiring enhanced durability and corrosion protection.
