HITEXBAU Achieves European Technical Assessment (ETA) for HTC Carbon Grids
April 2023 – Prague
HITEXBAU announces the successful award of European Technical Assessment ETA-23/0269 for its HTC carbon fibre reinforcement grids, issued by the Technical and Test Institute for Construction Prague, member of the European Organisation for Technical Assessment (EOTA).
Issued under Regulation (EU) No. 305/2011 (Construction Products Regulation) and based on EAD 260057-00-0303, the ETA establishes harmonized, independently verified performance for HITEXBAU carbon grids throughout the European Union.
This milestone enables CE marking and confirms compliance with European essential requirements for construction products.
Certified Product Portfolio
The ETA covers the following HTC product types:
- HTC 18/18-40 (24K)
- HTC 25/25-80 (24K)
- HTC 21/21-40 (48K)
- HTC 21/21-80 (48K)
- HTC 34/34-40 (48K)
These high-performance carbon fibre grids are designed for reinforcement of cement-, anhydrite-, and resin-based screeds, particularly in aggressive, corrosive, and chemically exposed environments.
Verified Structural Performance
Independent assessment under EAD 260057-00-0303 confirms:
- Tensile strength up to 211.3 kN/m (warp direction, HTC 21/21-80 48K)
- Low elongation (~1.0–1.2%), ensuring crack control efficiency
- Stable mechanical behaviour after alkali conditioning
- Stable performance after acid conditioning
- Verified residual tensile strength values exceeding 100% in several cases
- Defined grid geometry, coverage ratios, and mass per unit area
The ETA establishes a declared working life of 25 years under intended conditions of use.
This performance profile positions HTC grids as a technically robust alternative to conventional steel reinforcement in screed systems.
Regulatory Strength and Market Access
The assessment was carried out under:
- Construction Products Regulation (EU) No. 305/2011
- AVCP System 2+
- Continuous Factory Production Control
- Third-party oversight by a Technical Assessment Body
The ETA provides harmonized technical documentation supporting CE marking and specification across EU Member States.
Strategic Impact
The award of ETA-23/0269 marks a significant advancement in HITEXBAU's European expansion strategy.
Carbon reinforcement enables:
- Corrosion-free reinforcement systems
- Extended durability in aggressive environments
- Material-efficient screed reinforcement
- Lightweight, high-strength performance
- Reduced maintenance and lifecycle costs
By securing harmonized European approval, HITEXBAU reinforces its position at the forefront of advanced carbon-based reinforcement technologies.
