Logic UH FLEX

Flexible Epoxy System for Structural Repair, Strengthening, Waterproofing and Protection

Logic UH FLEX is a flexible epoxy-based system developed for the structural repair, strengthening, waterproofing, and protection of concrete and mineral substrates exposed to movement and dynamic loading. Unlike rigid repair materials, it accommodates vibration, thermal expansion, settlement, and structural movement while maintaining strong adhesion and long-term waterproofing performance. After curing, it forms a durable, flexible, and water-resistant polymer matrix that helps protect repaired areas against cracking, moisture ingress, and environmental stress. Ideal for professional construction, infrastructure, and rehabilitation projects, Logic UH FLEX is backed by a 20-Year Performance Guarantee when applied according to Logic Chemie guidelines.

Flexible Waterproofing for Dynamic Structures

Logic UH FLEX helps protect concrete structures against water ingress in areas exposed to movement, vibration, and changing service conditions. The flexible polymer matrix remains bonded to the substrate while maintaining a durable waterproof barrier. Its ability to accommodate movement makes it suitable for applications where conventional rigid repair materials may be susceptible to cracking or loss of performance over time.

Helps prevent water penetration through cracks and joints
Suitable for movement-prone structural areas
Supports waterproofing of foundations, basements, tunnels, and underground structures
Contributes to long-term moisture protection
Maintains performance under vibration and structural movement

Structural Bonding and Load Transfer

Logic UH FLEX provides strong adhesion between repair materials and existing substrates, helping restore structural continuity in damaged concrete elements. The system supports effective stress distribution within repaired areas while maintaining the flexibility required for structures exposed to movement and dynamic loading.

Strong adhesion to concrete and masonry
Supports structural continuity
Improves load transfer across repaired areas
Suitable for vibration-prone structures
Contributes to long-term structural reliability

Durable Repair of Cracks and Structural Defects

Logic UH FLEX is designed for the repair of cracks, joints, voids, and damaged concrete elements where both durability and flexibility are required. Following curing, the material becomes an integral part of the structure, providing reliable repair performance while accommodating movement that may occur during service life.

Structural Protection and Long-Term Durability

Logic UH FLEX combines structural repair, strengthening, waterproofing, and protection within a single flexible epoxy system.

Following curing, the material develops a durable polymer structure with strong resistance to moisture, weathering, and environmental exposure. Its flexible characteristics help maintain the integrity of repaired areas while reducing the risk of premature deterioration.

The system is suitable for both new construction and rehabilitation projects where long-term reliability and reduced maintenance requirements are important.

Backed by a 20-Year Performance Guarantee, Logic UH FLEX provides dependable protection for demanding structural repair and waterproofing applications.
