Professional Office Raised Access Floor Solution: HUIYA GRC800 Inorganic Cement Raised Access Floor

The HUIYA brand GRC800 Inorganic Cement Raised Access Floor (LIGHT-800LBS) is a next-generation green and eco-friendly network floor systematically improved and developed upon the traditional LIGHT SC800 steel raised access floor. The product is manufactured from natural inorganic materials including silicate, inorganic fiber, mineral fiber, and quartz sand, with an embedded 20×20 welded steel wire reinforcement mesh (wire diameter Φ2.2mm), formed through a high-pressure single-press molding process. The finished product contains no volatile toxic substances or radioactive materials, is fully biodegradable, and has a service life equivalent to that of the building itself – making it a truly eco-friendly inorganic raised access floor.

Each floor panel comes with built-in cable routing holes.

Support System

The pedestal system used in this project consists of H60–150mm standard galvanized steel pedestals in two types: center pedestals and border flat pedestals. Each pedestal is precision-assembled from an M8 bolt, circular steel cover plate, black PVC vibration-dampening pad, steel top plate (80mm × 80mm × 3.0mm), M18 threaded rod, locking nut, and steel base plate (95mm × 2mm). The nominal pedestal height ranges from 60mm to 150mm, with ±25mm fine adjustment via the threaded rod to accommodate floor-level deviations and ensure final surface-level accuracy.

The four corners of each floor panel are secured to the pedestal top plates via a corner-locking mechanism. The entire system requires no cross-beams, making installation quick and efficient.

It is one of Japan’s oldest manufacturers of adhesives and sealants and is listed on the Tokyo Stock Exchange. Headquartered in Osaka, Japan, its renowned brand “BOND” (ボンド) commands an exceptionally high market share and industry reputation in Japan’s construction, industrial, and consumer adhesive sectors. Konishi’s products are widely used in building structures, interior finishing, civil engineering, electronic manufacturing, and other fields, and are recognized for their outstanding product quality and rigorous environmental standards.

KU928C-X Product Technical Characteristics

BOND KU928C-X is a high-performance, single-component, moisture-curing polyurethane resin adhesive (Main Ingredients: Solvent-free Polyurethane Resin) specifically designed for bonding and fixing steel and plastic raised access floor pedestals to the subfloor. The product is a pale yellowish-white paste, packaged in a 760ml aluminum foil pack (2way Pack), equipped with a simple slot system and conical nozzle for direct use with a standard caulking gun.

The key technical specifications and characteristics of this product are as follows:

Environmental Rating: Compliant with JIS A 5536 F☆☆☆☆ (F-4 Star) standard — the highest environmental grade for formaldehyde emission under Japanese Industrial Standards.

VOC Control: Free of 13 harmful indoor chemical substances, with no added volatile organic compounds (VOCs) and virtually no odor.

Bonding Strength: 24-hour bonding strength of 2,750N and 7-day bonding strength of 3,483N (pedestal base plate to concrete substrate bonding test), ensuring long-term secure and reliable pedestal fixation.

Moderate Elasticity: The cured adhesive film retains moderate elasticity, effectively absorbing micro-vibrations generated during use of the raised access floor system and preventing friction noise between the floor panels and pedestals.

Weather Resistance: Excellent water, fire, and oil resistance, suitable for humid areas.

Safety: Contains no harmful solvents, is classified as a non-hazardous material, and features high flame retardancy.

Patented Applicator Design: Comes with a disposable patented adhesive spreading container with a built-in scraper function. After squeezing KU928 adhesive into the container, it can be evenly applied to the pedestal base plate. The container capacity precisely matches the volume of one KU928 cartridge, purpose-designed for large-area raised access floor installation scenarios to boost construction efficiency.

Application of KU928 Adhesive in This Project

During installation, operators apply KU928C-X adhesive via a dedicated caulking gun to the contact surface between the steel pedestal base plate (95mm × 95mm × 2mm) and the concrete subfloor, utilizing a moisture-curing reaction to achieve a strong chemical bond between the pedestal and the floor surface. This anchor-free bonding method completely eliminates the need to drill holes into the structural slab, effectively preserving the building’s structural integrity — making it especially suitable for leased commercial office spaces where damage-free removal may be required upon lease expiration.

In the office environments of semiconductor equipment companies, indoor air quality requirements are extremely stringent. By selecting KONISHI KU928 adhesive meeting the F-4 Star standard, harmful gas emissions are eliminated at the source, ensuring the health and safety of the office space.

Precision Craftsmanship: Full Construction Documentation of the 650-Square-Meter Project

In accordance with the HUIYA GRC800 raised access floor standard installation specifications, the construction process proceeds as follows: First, the room’s length and width dimensions are measured, and the number of full panels and edge-cut panel sizes are calculated. For this project, installation began with the first center pedestal placed 300mm from the wall along the length direction, with full panels laid outward in sequence. Once all full panels in the central area were installed, the actual dimensions of the remaining edge zones on both sides were measured, and panels were precision-cut using a dedicated cutting machine before being installed as edge panels to complete the full coverage. The same principle applies along the width direction. Edge areas are supported and fixed using border flat pedestals to ensure a tight finish against the walls.

Step 1: Raised Access Floor Base Layer Installation

The construction team first bonded the galvanized steel pedestal base plates firmly to the concrete subfloor on the original 14th floor of Huahong Tower using KONISHI KU928 adhesive. Each pedestal’s height was adjusted via the threaded rod to achieve a uniform level surface. The GRC800 inorganic cement raised access floor panels were then laid one by one, with each panel’s four corners precisely seated into the corner-locking mechanisms on the pedestal top plates, ensuring overall stability and consistency across the entire floor surface.

Across the 650-square-meter open office area, the raised access floor system is uniformly and precisely aligned, with tight and even gaps between panels and a stable, reliable pedestal system. The 60mm to 150mm void beneath the raised access floor provides ample routing space for subsequent network, power, and low-voltage cabling, allowing workstation wiring to be adjusted at any time according to actual needs — completely eliminating the exposed cables and safety hazards associated with traditional floor-level wiring. Each panel weighs only 13.5kg and can be easily lifted by a single person during subsequent maintenance, facilitating convenient inspection and servicing of cable infrastructure within the void.

Step 2: Surface Layer Installation and Finishing

After the raised access floor base layer installation was completed and overall levelness was verified, vibrant carpet tiles were laid on the surface. The carpet features a predominantly gray base tone accented with geometric color-block patterns in green, blue, and yellow. While maintaining the dignified professionalism of an office environment, the design incorporates an energetic and contemporary design language. The carpet tiles complement the GRC800 panels’ excellent surface flatness (±0.5mm) perfectly – after installation, the floor surface is highly level with no arching, no edge lifting, and outstanding visual consistency.

The completed office space is bright and open, with no noise, looseness, or soft spots when walking across the floor. The GRC800 panel’s uniform load capacity of 18.0 kN/m² and safety factor of 3.0 provide ample load-bearing margin for everyday office furniture, equipment, and foot traffic. Meanwhile, the sound-insulating design of the black PVC vibration-dampening pads atop the pedestals renders the entire floor system virtually silent during foot traffic, creating a quiet working environment for the semiconductor technology team that demands high levels of concentration.
