Retaining walls in Malaysia.
Reinforced earth (RE/MSE) walls, modular concrete block walls, RC cantilever walls, sheet piling, and gabion walls, designed and built by Infraconcrete's in-house team to BS 8002, BS EN 1997 (Eurocode 7), BS 8006, 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.
Five families, one specialist team.
Reinforced Earth (RE / MSE) walls
Geosynthetic or metallic reinforcement strips/grids embedded in compacted backfill behind facing panels or modular blocks. Most economical above 4-5 m. Tolerates settlement. Common on highway corridors, hillside developments, and mass-fill platforms.
Modular block walls (segmental retaining walls)
Precast concrete blocks dry-stacked with mechanical interlock. Up to ~8-10 m unreinforced; higher with geogrid. Fast install, textured/coloured aesthetic finishes available. Common on residential, township, and parks.
RC cantilever and counterfort walls
Cast-in-place reinforced concrete cantilever walls, economical to ~6 m, with counterforts above. Used where settlement tolerance is low, backfill space is constrained, or aesthetic/exposure dictates monolithic concrete.
Sheet piling and soldier piling
Steel sheet piles for excavation support, basement temp works, riverside, marine, and certain permanent retaining applications. Soldier piles with timber or concrete lagging for granular soils. We size depth, profile, and tieback design to the load case.
Gabion and crib walls
Wire-mesh baskets stone-filled, stacked to form gravity walls. Permeable, flexible, naturalistic. Suited to riverbanks, low retaining heights, and erosion-prone sites where rigidity isn't required.
Combined and hybrid systems
Higher walls often combine: RE wall on top of an RC base, or sheet piling with a tied-back upper modular section. We design and build the whole system rather than coordinating between specialist trades.
Picking the right wall for the right site.
Hillside developments & townships
RE walls and modular block, economical at scale, faster install, accommodate settlement on filled platforms.
Highway corridors and embankments
RE walls and RC cantilever for height and load. Fascia/aesthetic options for visible faces. Coordination with traffic management for live works.
Basement and excavation support
Sheet piling and soldier piling for temporary works. Sometimes secant/contiguous bored pile walls for permanent basement walls.
Riverside, marine, naturalistic
Gabion and crib walls, permeable, flexible, blend into landscape. Or coated steel sheet piling where structural capacity is needed.

RC walls, cantilever to counterfort.
RC wall (Reinforced Concrete retaining wall) is the cast-in-place reinforced-concrete family. The wall stem and base slab are reinforced concrete elements, designed as a single structural unit to resist lateral earth pressure by cantilever or counterfort action. Used where stiffness is required, settlement tolerance is low, backfill space is constrained, or the architectural intent demands a monolithic concrete face. Infraconcrete is the leading RC wall contractor in Malaysia.
RC wall sub-families
- RC cantilever wall: the workhorse RC wall. Stem with vertical reinforcement, base slab with horizontal reinforcement, designed as a cantilever from the base. Economical up to ~6 m height.
- RC counterfort wall: for heights above ~6 m. Periodic vertical counterfort buttresses on the back face transfer stem load into the base, reducing stem thickness. Economical 6 to 12 m.
- RC gravity / semi-gravity wall: massive concrete section resisting overturning by self-weight. Used for low heights (under ~3 m) where simplicity of construction outweighs material economy.
- RC crib wall: stacked precast RC stretcher and header units forming a cellular wall, infilled with granular material. Gravity action. Used on aesthetically sensitive sites.
RC wall specification
| Parameter | Typical specification | Standard |
|---|---|---|
| Concrete grade | 30 to 50 N/mm² (Grade 30 to 50) | BS EN 1992-1-1 / JKR |
| Stem thickness | 250 to 600 mm (taper to top) | Per design |
| Base slab thickness | 400 to 1000 mm | Per design |
| Reinforcement | Y10 to Y32 high-yield bar | BS 4449 / MS 146 |
| Cover to reinforcement | 50 to 75 mm (exposure class XC3 to XC4) | BS EN 1992-1-1 Table 4.4 |
| Wall heel and toe extension | 0.5 to 0.7 x stem height typical | Per design |
| Weep pipes | 50 to 75 mm PVC at 2 to 3 m spacing | BS 8002 / JKR |
| Back-of-wall drainage | Granular zone + geotextile filter + 100 mm perforated UPVC subsoil drain | BS 8002 / BS 6031 |
| Design code | BS 8002, BS 8004, BS EN 1992, BS EN 1997 (Eurocode 7) | Project spec |
When RC wall is the right call: basement walls, tight urban footprint, fire-rating or chemical-resistance requirements, monolithic exposed concrete architecture, retaining walls in front of structures where settlement tolerance is tight (millimetres rather than centimetres), federal projects where the consultant has specified RC explicitly.

The reinforced-soil wall family.
Infraconcrete is the leading RE wall, RS wall, and MSE wall contractor in Malaysia. The three terms cover overlapping technologies and are often used interchangeably in Malaysian industry practice. The distinction matters for design-spec compliance but not for engineering function. Group company Starwall Sdn Bhd is the sole appointed STRATA Geosystems distributor for Malaysia, so the supply + design + install is delivered under one ownership.
Terminology clarified
- RE wall = Reinforced Earth wall: historically refers to the legacy steel-strip reinforced soil wall family, patented in France in the 1960s, using steel-strip reinforcement embedded in compacted granular backfill behind precast concrete facing panels. In Malaysian practice today, "RE wall" is often used loosely to mean any reinforced-soil wall regardless of reinforcement type.
- RS wall = Reinforced Soil wall: modern term for geogrid or geosynthetic-reinforced soil retaining wall. Same engineering principle as RE wall but with polymeric geogrid (StrataGrid PET, or biaxial PP) replacing steel strips. Most modern Malaysian projects.
- MSE wall = Mechanically Stabilized Earth wall: the umbrella term that covers both RE and RS. "Mechanically stabilized" means soil reinforced by mechanical means (whether steel or geosynthetic) to develop tensile capacity within the soil mass. The current global standard term used in FHWA and AASHTO codes.
RE / RS / MSE wall sub-families
- Steel-strip reinforced (legacy RE wall): galvanised steel strips with proprietary connection to precast concrete facing panels. Still used on certain federal infrastructure projects, particularly bridge abutments.
- Geogrid-reinforced with precast panel facing (StrataWall-class): StrataGrid uniaxial PET geogrid (30 to 400 kN/m grades) connected to precast concrete facing panels. The modern federal-grade default for highway and rail embankment retaining.
- Geogrid-reinforced with modular block facing (StrataBlock-class): StrataGrid layers connected to dry-stacked precast concrete blocks. Up to ~10 to 12 m height economical. The default for hillside developments and residential projects.
- Reinforced soil slope (RSS) at sloped face: 30 to 70 degree face angle with geogrid-reinforced fill, vegetated finish. Cheaper per cubic metre than vertical wall, takes more footprint. See reinforced soil slopes for the dedicated guide.
RE / RS / MSE wall specification
| Parameter | Typical specification | Standard |
|---|---|---|
| Reinforcement (geosynthetic) | StrataGrid uniaxial PET 30 to 400 kN/m | BS EN ISO 10319 / ASTM D6637 |
| Reinforcement (steel) | Galvanised steel strip 50 x 4 to 50 x 5 mm | BS 8006-1 / FHWA-NHI-10-024 |
| Reinforcement vertical spacing | 400 to 800 mm typical | Per design |
| Reinforcement length | 0.7 to 0.9 x wall height typical, min 3 m | BS 8006-1 / FHWA |
| Backfill (select granular) | Friction angle ≥ 32 deg, free-draining, plasticity index ≤ 6 | BS 8006-1 / FHWA-NHI-10-024 |
| Compaction | 95 to 98 percent MDD (BS 1377 / JKR) | BS 1377-4 |
| Facing (precast panel) | 1.5 x 1.5 m cruciform or fishplate, 150 to 200 mm thick | StrataWall / equivalent |
| Facing (modular block) | StrataBlock dry-stack 200 to 300 mm course height | NCMA / BS 14475-1 |
| Wall height range | 3 to 25 m+ typical; up to 35 m on terraced systems | Per design |

Which wall type, which site.
Cost and programme comparison across the two dominant families. Selection is design-led, but the matrix below gives the indicative trade-offs that drive most Malaysian decisions.
| Criterion | RC Wall | RE / RS / MSE Wall |
|---|---|---|
| Economical height range | 2 to 8 m typical | 4 to 25 m+ (geogrid systems) |
| Cost per m² of wall face | Higher per m² (concrete + rebar intensive) | Lower per m² (fill is cheaper than concrete) |
| Speed of construction | Slower (formwork, rebar, cure) | Faster (concurrent fill placement and panel/block fixing) |
| Settlement tolerance | Low (rigid concrete cracks at differential settlement) | High (segmented facing accommodates settlement) |
| Foundation requirements | Continuous strip footing or piled raft | Granular levelling pad typical, sometimes piled |
| Backfill footprint behind wall | Minimal (the wall stem is the structure) | Significant (reinforcement length 0.7 to 0.9 x wall height) |
| Aesthetic options | Monolithic concrete, stone-clad, formliner texture | Precast panel patterns, textured modular block, vegetated face on RSS |
| Design life | 50 to 120 years (per concrete cover and exposure class) | 75 to 120 years (per reinforcement coating and design code) |
| Typical Malaysian applications | Basement walls, urban tight sites, monolithic-architecture, fire-rated walls, federal RC-specified projects | Highway corridors, hillside developments, township platforms, bridge abutments, mass-fill structures |
Our recommendation framework: for wall heights under 4 m and tight footprint, RC cantilever is usually the right call. For heights 4 to 12 m on developable footprint, RS / MSE / RE wall (geogrid or steel-strip) is typically more economical and faster. For heights above 12 m, RE / RS / MSE wall is almost always the default unless the project spec mandates RC. We deliver both families in-house with no commercial bias either way. See the dedicated retaining walls compared matrix for the full multi-criteria comparison covering all wall families.
From foundation to finished face.
RC wall installation sequence
Excavate to foundation level, lay blinding, fix reinforcement and starter bars per design, erect formwork, pour base slab, cure. Fix stem reinforcement, erect stem formwork, pour stem in lifts (typical 3 m max lift height, sometimes per pour to avoid cold-joint design penalty). Strip formwork after specified cure. Backfill behind wall in lifts with weep pipes and granular drainage zone installed per design. Surface finish per architectural spec.
RE / RS / MSE wall installation sequence
Excavate and prepare levelling pad (typical granular pad 150 to 300 mm thick on prepared subgrade). Set first course of facing (precast panel or modular block) to design line and level. Place first geogrid or steel-strip layer at design connection elevation, anchor into facing. Place compacted granular fill above geogrid layer to design lift thickness, compact to 95 to 98 percent MDD. Continue facing-fill-reinforcement cycle to design wall height. Drainage installed concurrent with fill placement (back-of-wall granular zone, geotextile filter, perforated subsoil drain).
Common installation across all wall types
ITP submitted before mobilisation. Material certificates reviewed at receipt. Compaction test per lift per design frequency. As-built drawings, test record, and maintenance schedule submitted at handover.
Where retaining walls do the work.
Federal expressway and highway
RE / MSE walls at significant heights (8 to 25 m+) along federal alignments. EKVE, KESAS, ELITE, NSE, Pan Borneo and similar corridors. Live-traffic construction with staged closures. See highway slope contractor.
Federal rail (ECRL, KTM)
MSE walls at bridge abutments and embankment retention. Possession-window logistics. Section 3 of ECRL has substantial MSE wall scope. See railway slope contractor.
Hillside developments
Modular block walls (StrataBlock) between platforms, RC cantilever walls in tight urban footprints, RE / MSE walls for taller platform retention. DBKL, MBPP, MPSJ, MBPJ, MBSA, MBSJ hillside guidelines. See hillside development and the hillside development master guide.
Township and industrial platforms
Multi-discipline platform creation: bulk earthworks + perimeter retention + slope protection + drainage as one integrated scope. RC and RE / MSE walls deployed based on platform edge condition and architectural intent. See land development and land creation.
Basement excavation and urban tight sites
RC cantilever walls for permanent basement retention. Sheet piling for temporary excavation support. Soldier piling with lagging in granular ground. See sheet piling.
Mobilisation
Typical core crew: 1 supervisor, 1 site engineer, 1 safety officer, 2 to 3 wall crews (formwork team for RC, panel-erection team for RE / MSE, modular block crew for SRW), 1 surveyor. Equipment: 20 to 50 tonne excavator for earthworks, batching plant for RC pours (or transit mixer supply), crane for precast panel handling, smooth-drum and padfoot rollers for backfill compaction. Standard mobilisation 2 to 4 weeks from contract signature. Production rates: RC wall typically 5 to 15 m² per crew per shift, RE / MSE wall 20 to 50 m² per crew per shift (faster due to no cure time on the wall face).
Specify the system, or specify the outcome.
Several proprietary retaining wall systems are well-established in Malaysia, each a branded product from a specific manufacturer or licensor. Where the project specification names a specific proprietary system, Infraconcrete delivers that system to the manufacturer's certified detail. Where the specification leaves the system open, we recommend the most appropriate family (RC, RE, RS, MSE, modular block, gabion) for the site and design the wall to first principles. Infraconcrete is the leading independent retaining wall contractor in Malaysia, with no commercial bias toward any single proprietary system.
Steel-strip reinforced soil walls (legacy patented systems)
The legacy steel-strip reinforced soil wall family uses galvanised steel strip reinforcement with proprietary cruciform precast facing panels, originated in France in the 1960s and licensed internationally since. Independent alternative for this wall family in Malaysia: Infraconcrete delivers the equivalent engineering function using geogrid-reinforced soil walls (StrataWall precast-panel, StrataBlock modular block) supplied via group company Starwall Sdn Bhd (sole STRATA Geosystems Malaysia distributor). For projects where the spec mandates steel-strip reinforcement, we also install steel-strip reinforced walls to BS 8006-1 Section 6. CIDB G7, ISO 9001:2015. Same engineering performance, independent contractor, single-team accountability.
Modular reinforced soil wall families (vegetated, gabion-faced, cellular)
Modular reinforced soil walls are supplied through several proprietary product families in Malaysia, including modular block with geogrid, vegetated face, gabion-style face, and cellular crib variants. Independent alternative for this wall family in Malaysia: Infraconcrete delivers the equivalent through StrataBlock (modular block + StrataGrid geogrid), vegetated reinforced soil slope (RSS), gabion walls, and crib wall systems to the same BS 8006-1 / FHWA-NHI-10-024 / NCMA design framework. Cost-comparable, design-led, and not tied to a single product line.
Gabion-faced and mesh-reinforced wall families
Gabion-faced reinforced soil walls combining hexagonal mesh facing with horizontal mesh reinforcement, along with modular block and precast panel variants, are widely supplied in Malaysia. Independent alternative for this wall family in Malaysia: Infraconcrete delivers gabion walls with geogrid reinforcement, modular block walls (StrataBlock), and precast-panel MSE walls (StrataWall) covering the full equivalent product range. To the same BS / FHWA / AASHTO / JKR specifications.
Geogrid + modular block paired systems
Several proprietary geogrid + modular block paired systems are distributed in Malaysia, typically combining a polymeric geogrid line with a paired modular block facing line. Independent alternative in Malaysia: Infraconcrete delivers equivalent geogrid-reinforced modular block walls using StrataGrid PET supplied via group company Starwall (sole STRATA Geosystems Malaysia distributor), to BS 8006-1 / NCMA / AASHTO design standards. Equivalent performance, independent supply chain.
Anchored cellular wall systems
Anchored cellular walls combine ground anchor capacity with a cellular block or precast face for tall, near-vertical retention. Independent alternative in Malaysia: Infraconcrete delivers anchored retaining wall systems combining ground anchors with either RC face or cellular block construction to project-specific design.
When to specify Infraconcrete instead of a proprietary system
- When you want a single-team accountable contractor (design + supply + install under one CIDB G7 banner) rather than a chain of licensor + appointed sub-contractor + main contractor.
- When the project budget calls for the engineering function without the proprietary brand premium.
- When the project schedule requires faster mobilisation than international supply chains can offer.
- When the design is open and the consultant wants engineering recommendation rather than product fitment.
- When the project is a federal scope (JKR, MOW, LLM) and Infraconcrete has prior project experience in the equivalent corridor.
Important: We deliver proprietary systems to the manufacturer's certified detail where the project spec mandates them. The above is about offering the choice when the spec is open.
