CTI Inspection provides façade inspection and quality control services—in compliance with international standards—for high-rise structures, commercial buildings, and sophisticated architectural projects, covering GFRC (Glass Fiber Reinforced Concrete), aluminum composite, glass curtain walls, natural stone, marble cladding, and exterior composite systems. We oversee the entire process—from production and installation to material quality, anchorage strength, and water-tightness testing—through an independent, objective lens.

Our Scope of Façade Inspection and Oversight

GFRC / GRC Panel Production and Installation Inspection

Our expert engineers conduct inspections of GFRC (Glass Fiber Reinforced Concrete) panels, including checks on structural frame welding, concrete strength, surface quality, and on-site installation anchorages.

Curtain Wall, Structural Glass, and Aluminum Façade Inspections

We verify the technical compliance of laminated and tempered exterior glass, structural silicone and gasket applications, façade connection details, thermal insulation, wind load resistance, and the optical/safety properties of the glass, all in accordance with international specifications.

Natural Stone, Marble, and Composite Façade Cladding Inspections

We inspect natural stone, marble, granite, and honeycomb stone panels used in façades, ensuring their compatibility with mechanical support systems, verifying concealed anchorage installations, and checking for proper stone thickness and the absence of cracks or defects, in line with project specifications.

Façade Insulation and Water-Tightness Testing

Through on-site spray and water-tightness testing, we assess the quality of façade insulation and waterproofing. All critical connection points—including joints between glass or stone panels—are subjected to third-party inspection to identify and mitigate any risks of water leakage.

Torque/Pull-Out Testing for Anchorages and Fasteners

Torque and pull-out tests are conducted on-site—and subsequently documented in reports—for the anchor brackets, welds, and fasteners that secure facade panels, glass cassettes, and stone-supporting structures to a building’s primary load-bearing framework.

Frequently Asked Questions (FAQ)

1. What is GFRC (GRC), and why should it be inspected when used on building facades?
GFRC (Glass Fiber Reinforced Concrete) is a concrete cladding material reinforced with alkali-resistant glass fibers. Because it is subjected to wind loads and seismic movements on high-rise buildings, it is critical that the structural welds, anchorage points, and the quality of panel production are inspected by an independent Type A Inspection Body.

2. What aspects are examined during the inspection of natural stone and marble facades?
For natural stone and marble facade installations, inspections cover stone thickness, compatibility with the supporting sub-frame, the strength of mechanical (clip-based) or concealed anchorage connections, and the compliance of joint insulation with relevant standards.

3. What checks are performed during the inspection of glass curtain wall facades?
Inspections for glass facades include verifying glass panel thickness, confirming tempering/lamination processes, conducting structural silicone adhesion tests, checking installation tolerances for aluminum cassettes, and assessing resistance against wind loads.

4. What Stages Does a Façade Inspection Include?
The façade inspection process encompasses the verification of materials and approved details prior to fabrication, oversight during the factory production phase, checks on the installation of anchors and structural framing on-site, and water-tightness testing before final handover.
