Question 1

What is the cost of a gabion wall in Malaysia?

Accepted Answer

Indicative cost per m cubed of wall volume (supply and install, 2026 Malaysian projects): galvanised box wall RM 380-520, Galfan zinc-aluminium alloy RM 450-600, PVC-coated over galvanised RM 520-720. Gabion mattress per m squared of mattress area at 300 mm thickness: RM 180-260 galvanised, RM 230-340 PVC-coated. Welded mesh gabion: 20-40 percent premium over equivalent woven hexagonal mesh. Project-specific pricing depends on site access, mesh and stone delivery distance, wall geometry complexity, and any face-finish requirements.

Question 2

How is gabion wall cost calculated?

Accepted Answer

Box wall: cost per m cubed of wall volume. Calculate wall volume (length x height x base width). Typical gabion wall base width is 0.5-0.7 times the wall height for self-stable design. Example: 100 m long, 4 m height, 0.6H base width (2.4 m) = 960 m cubed wall volume. At RM 450 per m cubed galvanised = RM 432,000 indicative budget. Mattress: cost per m squared of mattress area. Example: 200 m riverbank, 5 m bank width = 1,000 m squared. At RM 220 per m squared galvanised mattress = RM 220,000. Add 10-15 percent for site preparation, geotextile underlay, and edge anchoring.

Question 3

PVC-coated vs galvanised gabion, which is more cost-effective?

Accepted Answer

Per unit cost: galvanised cheapest, PVC-coated 25-50 percent premium. Per year of design life: PVC-coated typically cheaper. Galvanised gabion design life 25-50 years inland in neutral residual soil. PVC-coated design life 50-100 years (mandatory for coastal Pasir Gudang, Port Klang, Penang Port, brackish water, polluted urban streams, chloride-rich groundwater). For inland residential or commercial projects: galvanised wins on initial cost. For coastal, river training (long-term hydraulic exposure), or critical infrastructure: PVC-coated wins on lifecycle cost.

Question 4

How does gabion cost compare to other retaining wall types?

Accepted Answer

For heights 1-8 m, gabion at RM 380-720 per m cubed is typically cheaper than equivalent RC cantilever (RM 600-1200 per m squared) and competitive with modular block SRW (RM 380-700 per m squared). MSE wall (RM 450-900 per m squared) wins on heights above 8 m. Gabion advantages over alternatives: permeable (no drainage system needed), flexible (tolerates differential settlement), vegetated-face option, fast construction. Gabion disadvantages: wider base footprint (0.5-0.7H vs RC cantilever 0.4-0.5H), face requires hand-packing for aesthetic finish.

Question 5

What is the cost of gabion mattress for scour protection?

Accepted Answer

Gabion mattress (low-profile, 150-300 mm thickness) for riverbank scour protection, bridge-pier protection, drainage chute armoring: RM 180-260 per m squared galvanised, RM 230-340 per m squared PVC-coated. Plus geotextile underlay (nonwoven PP filter) typical RM 8-15 per m squared. Plus edge anchoring (trench anchor at upstream and downstream extents): typical lump sum RM 30,000-80,000 per project. Total project cost for typical 1,000 m squared riverbank application: RM 230,000-380,000 indicative.

Question 6

What's included in a gabion wall quote?

Accepted Answer

Standard scope: gabion mesh supply (per BS EN 10223-3 or BS EN 10223-8 coating per BS EN 10244-2 or BS EN 10245), hard angular stone fill 100-200 mm (typical igneous rock granite or basalt), geotextile underlay where required, basket assembly + lacing, foundation preparation, hand-packing of face stones, machine-tip of interior, lid closure, course-by-course construction, QA records (stone source certificate, mesh certificate of conformance, lacing wire batch). Typically excluded: ground investigation, geotechnical design (if separately engaged consultant), authority fees, GST, contingency, performance guarantee, CAR insurance.

Mesh coating	Indicative cost per m³	Design life	Where to use
Heavy galvanised (Class A, zinc 245-300 g/m²)	RM 380-520	25-50 years	Inland sites, neutral residual soil, freshwater. Base option for most Malaysian projects
Galfan (Zn-Al 95/5 or 90/10)	RM 450-600	50-75 years	Mild to moderate aggressivity. Compromise between galvanised cost and PVC durability
PVC-coated over galvanised	RM 520-720	50-100 years	Coastal (Pasir Gudang, Port Klang, Penang Port, Kuantan Port), brackish, urban polluted streams, chloride-rich groundwater
Welded mesh gabion (any coating)	+20-40% on equivalent woven hexagonal	per coating class	Architectural urban walls, sound barriers, commercial development walls with face-line precision requirement

Mattress type	Thickness	Indicative cost per m²	Application
