Can your factory noise barrier walls be installed on existing concrete slabs without deep foundations?

Yes — we offer two surface-mounted options: (1) Base plate connection: H-beam posts welded to 400mm×400mm×20mm steel base plates, bolted to the existing concrete slab with 8× M24 chemical anchor bolts (HILTI HIT-HY 200 or equivalent). This requires a minimum slab thickness of 200mm with reinforcement. Suitable for wall heights up to 4.0m under 0.75 kN/m² wind load. (2) Concrete ballast blocks: precast concrete blocks (1,000mm×500mm×500mm, ~600kg each) placed behind each post and connected with steel brackets. No drilling required — suitable for leased facilities where slab modifications are prohibited. For walls exceeding 4.0m or high-wind zones (>1.0 kN/m²), deep foundations remain necessary. We can arrange structural assessment of your existing slab based on reinforcement drawings and concrete core samples.

How do you handle thermal expansion and panel joints in long noise barrier walls?

For long barrier walls (100m+), we incorporate expansion joints at 30m intervals maximum. Each expansion joint consists of: (1) A double-post arrangement (two H-beams side by side with 10mm gap), (2) Panels on each side independently fixed to their respective posts, (3) EPDM rubber expansion joint filler strip between adjacent panels (compressible to 50% of original thickness), (4) Aluminum cover flashing over the joint to maintain acoustic seal while allowing movement. The galvanized steel panels have a thermal expansion coefficient of 12 × 10⁻⁶/°C — for a 30m section with 50°C temperature swing, thermal movement is approximately 18mm, which the expansion joint accommodates. Panel-to-panel horizontal joints are sealed with closed-cell EPDM gaskets (compressed 30% at installation) that maintain acoustic seal for 15+ years. All fasteners are stainless steel to prevent galvanic corrosion.
