Guniting & shotcrete in Malaysia.
High-velocity sprayed concrete on slope faces, rock faces, tunnels, and structural repairs. Wet-mix and dry-mix delivered by Infraconcrete's in-house crews to ACI 506, EN 14487, and JKR specifications. CIDB G7. ISO 9001:2015. Trusted by property developers, consulting engineers, C&S and geotechnical consultants, quantity surveyors, main contractors, and government agencies.
Sprayed concrete on slope and rock faces.
Guniting originally meant the dry-mix process, dry cement and aggregate conveyed in compressed air, water added at the nozzle. Shotcrete is the modern umbrella term that covers both dry-mix and wet-mix processes. In Malaysia and JKR specifications, both terms are used; the technique is the same, concrete fired at high velocity onto a prepared surface, where it consolidates on impact into a dense, durable layer.
The result is a structural skin that resists tropical rainfall, surface erosion, and weathering. Combined with welded mesh and bearing plates onto soil nails or rock bolts, it forms the structural face of a reinforced slope. Standalone, it protects a competent face from progressive ravelling.
Four scenarios where shotcrete delivers.
Soil-nailed slope facing
The structural face on a soil-nailed slope. Mesh fixed across, bearing plates onto each nail, shotcrete sprayed in lifts to design thickness.
Rock-bolted face protection
Combined with rock bolts on cut rock faces, the bolts anchor blocks, the shotcrete encapsulates the face and prevents ravelling.
Tunnel and portal lining
Initial support on tunnel excavation and stabilization at portals. Often fibre-reinforced for ductility.
Structural repair and re-profiling
Repair of damaged concrete structures, re-profiling of weathered surfaces, and pool/water-retaining linings.
Five stages, delivered in-house.
Surface preparation
Clean the receiving surface, remove loose material, install drainage and weep pipes. Confirm receiving surface meets the spec.
Mesh and bearing-plate fixing
Welded BRC mesh (typically A98) fixed across the face with mesh tying. Bearing plates onto each nail/bolt head with the correct standoff.
Mix design and equipment qualification
Mix design submitted and approved per spec. Trial panels per ACI 506 / EN 14487. Nozzleman certified per the standard.
High-velocity application
Wet-mix or dry-mix per the spec. Sprayed in lifts to design thickness. Accelerator dose for overhead and high-rebound conditions. Rebound managed and disposed per environmental controls.
Curing and acceptance testing
Curing per spec. Cube/core compressive strength tests, thickness verification by depth probes or coring, visual inspection for voids/laminations. Reports submitted to the consultant.
Technical envelope, at a glance.
Indicative ranges. Final values are always design-led and verified against the consultant's specification.
| Parameter | Typical range | Notes |
|---|---|---|
| Process | Wet-mix or dry-mix | Wet for high-volume; dry for tight access and low-volume |
| Compressive strength | 30 - 40 N/mm² @ 28 days | Higher grades available per design |
| Thickness | 75 - 150 mm in lifts | Per design and exposure class |
| Reinforcement | BRC A98 mesh or fibres | Synthetic or steel fibres for FRS |
| Accelerator | Per design and orientation | Higher dose for overhead / vertical |
| Drainage details | Weep pipes through mesh, chute drains down face | Per drainage scheme |
| Standards | ACI 506, EN 14487, BS EN 14487-1, JKR | Project spec governs |
