Successful Application of High-Performance Chemical Anchor in Large-Scale Building Renovation
High Performance Epoxy Chemical Anchor For Structural Strengthening
In urban renewal and building renovation projects, it is common to encounter the need for structural strengthening, equipment relocation, or installation of new support systems. For aging concrete structures, especially when installing threaded rods or rebars into load-bearing elements, ensuring anchoring strength and long-term durability is critical to overall structural safety. Chemical anchors, as high-performance bonding solutions, play a key role in modern construction due to their superior adhesion, high load capacity, and installation flexibility.
How High-Performance Chemical Anchors Improve Structural Safety and Efficiency in Building Renovation Projects
This case study presents how a Good Use customer successfully improved structural safety and optimized construction efficiency by adopting a high-performance chemical anchoring solution in a large-scale commercial building renovation project.

Challenges: Structural Upgrade Under Time and Site Constraints
The client was undertaking a major commercial building renovation project and required a reliable anchoring solution that could meet both structural and construction demands. The project presented three main challenges:
➤ Structural Load Requirements
New curtain wall supports and heavy equipment installations required secure anchoring into the existing concrete structure, involving the installation of threaded rods and rebars.
➤ Existing Concrete Conditions
The existing structure had been in service for many years, increasing uncertainty in anchoring performance and requiring a more reliable solution than traditional mechanical anchors.
➤ Tight Construction Schedule
The work had to be carried out within an operational commercial environment, requiring minimal disruption and efficient construction workflow.

Solution: GU-500SD High-Performance Epoxy Chemical Anchor
To meet both structural safety and construction efficiency requirements, the project team selected - GU-500SD Epoxy Chemical Anchor
Key benefits include:
• High bonding strength for heavy-duty anchoring
• Non-shrink formulation for long-term stability
• Suitable for general existing concrete conditions
• Low odor, ideal for indoor and operational environments
• Non-sag properties, suitable for overhead and vertical applications
To ensure compliance with engineering standards and project approval requirements, GU-500SD provides:
• ETA-24/0928 certification
• CE marking (European standard)
• Assessed according to EAD 330087-01-0601
• Suitable for use in non-cracked concrete conditions

Installation Process
1. Drilling and Hole Cleaning
Drill according to specified diameter and depth, and thoroughly clean the hole to remove dust.
2. Injection from Bottom Up
Inject adhesive using a mixing nozzle, filling from the bottom to avoid air voids.
3. Rod/Rebar Installation
Insert threaded rods or rebars with a twisting motion to ensure full bonding.
4. Curing and Testing
Allow proper curing time before conducting pull-out tests for verification.
GU-500SD epoxy anchor is safe and effective in improving construction efficiency
Results & Performance
The use of GU-500SD delivered significant improvements:
✔ Enhanced Load Performance - Up to 30–80% higher load capacity compared to traditional mechanical anchors
✔ Improved Construction Efficiency - Streamlined installation process reduced overall project duration by approximately 20–25%
✔ Increased Structural Reliability - Non-shrink properties reduce long-term loosening risks
✔ Higher Project Confidence - ETA and CE certifications increased trust from consultants and stakeholders
✔ Reduced Impact on Operations - Low-odor formulation minimized disruption in occupied spaces
GU-500SD is not only a high-performance chemical anchor, but also a reliable and engineer-approved anchoring solution designed for structural safety.
In this project, it successfully enabled the construction team to complete high-quality structural strengthening under existing building constraints and tight timelines, demonstrating its value in modern building renovation and heavy-duty anchoring applications.
