Installation of concrete HDB wall panel service Singapore

Concrete HDB wall panels refer to precast concrete wall components used in the construction of Housing & Development Board (HDB) flats in Singapore. These panels are part of the prefabricated building system, which allows for faster, more efficient, and higher-quality construction of public housing.

Installation of concrete HDB wall panels involves lifting precast panels into position using a crane, aligning them accurately on marked locations, securing them with temporary supports, and fixing them with grout and mechanical connections. The joints are sealed, surfaces are finished, and all works comply with safety and HDB standards.

Concrete HDB wall panel used in several area as like Exterior façade walls, Party walls (between units), Shear walls (resist lateral loads), Bathroom/kitchen enclosures etc.

• Precast structural or non-structural walls, manufactured off-site in a controlled factory environment.
• Delivered to the construction site and installed using cranes.
• Common in Prefab Prefinished Volumetric Construction (PPVC) and Precast Concrete Construction (PCC).

• Structural Wall Panels : Load-Bearing Wall Panels Carry structural loads (e.g., floor slabs above). Typically used for internal partition walls and external facades. Often have embedded reinforcement and openings for doors/windows. Typically used in prefabricated HDB flats (precast concrete construction). Cannot be hacked, removed, or altered without HDB and PE approval.

• Non-Structural Wall Panels : Act as partitions or external façade walls. May still be concrete, but not load-bearing. More flexibility for minor modifications (with HDB permission).

• Precast Concrete Panels : Factory-made and transported to the site for installation. Faster to install and commonly used in newer HDB construction. Includes hollow-core, solid, or sandwich panels (with insulation).
• Cast-in-Situ Panels : Poured and cured directly at the construction site. Common in older HDB flats (e.g. slab block or point block designs).

• Material : Reinforced concrete (with steel bars inside)
• Function : Load-bearing or partition wall
• Thickness : Typically 150–200 mm for structural walls
• Finish : May be bare concrete, plastered, or painted
• Fire-Rated : Usually fire-rated to meet building code requirements

• Material : Reinforced concrete (with steel bars inside)

• Thickness : Typically 150–200 mm for structural walls
• Finish : May be bare concrete, plastered, or painted
• Fire-Rated : Usually fire-rated to meet building code requirements

• Planning & Approval : All structural changes, including concrete panel installation, must be approved by HDB. Hire a PE (Professional Engineer) For load-bearing walls or structural works, a PE must assess the design and submit calculations. Obtain renovation permit Work must only commence after approval.
• Site Preparation : Clear the area where the wall panel will be installed. Verify alignment and wall layout using laser level or string lines. Install guide markings on floor and ceiling to guide panel placement.
• Material Handling : Use lifting equipment (e.g., chain blocks, small cranes) if panels are heavy. Panels should be handled with care to avoid chipping or cracking.
• Positioning the Wall Panel : Place a neoprene pad or damp-proof membrane on the base where the panel will sit. Lift and position the precast concrete panel into place. Use temporary supports or braces to hold the panel upright and aligned.
• Anchoring / Fixing : Drill holes into the slab or existing walls for mechanical anchors. Use chemical anchors or expansion bolts for secure fixing. Tie in reinforcement bars if the wall is structural and part of the load-bearing system.
• Sealing Joints : Apply non-shrink grout or concrete mortar at the base and sides. Use PU foam, silicone, or joint sealant for any gaps depending on whether it's interior or exterior.
• Finishing : Apply skim coat or plaster to create a smooth finish. Paint or apply wall finish as needed.
• Inspection : Final inspection by HDB (or supervising PE) to ensure safety and compliance. Remove temporary bracing only after approval.
