Soil nail contractor in Malaysia.
Infraconcrete Construction Sdn Bhd is a specialist soil nail installation contractor across Malaysia. CIDB Grade G7 (highest contractor grade), ISO 9001:2015 certified. 23 client projects delivered 2022 to 2026 including federal corridor scope: EKVE 450,000 m squared protected, ECRL Section 3 along 42 km and 64 km of alignment, Lingkaran Tengah Utama Kelantan. Five soil nail applications: hillside cut slopes, distressed slope remediation, top-down basement excavation, road widening at toe of cut, bridge abutment soil nail walls. All five BS 8081 tests delivered in-house with calibrated load cells. Coverage all 13 states plus Labuan.
Five soil nail installation applications.
Hillside cut slope soil nailing
Standard hillside township and commercial development cut. Nail length 8-15 m typical, spacing 1.5-2.5 m grid, inclination 10-15 degrees below horizontal. Drilled-and-grouted Y20 to Y32 high-yield steel or self-drilling hollow bar (R32-R76) for collapsing-ground conditions. Shotcrete and welded mesh facing.
Distressed slope remediation
Existing slope showing visible movement, cracks, post-monsoon distress. 24-48 hour emergency mobilisation Klang Valley. Investigation tests + interim stabilisation + permanent works execution. Pairs with horizontal drains where groundwater is the failure driver.
Top-down basement excavation
Commercial basements, MRT and LRT cut-and-cover stations, dense urban hillside basements. Basement perimeter cut in 1.5-2 m lifts top-down with nails and shotcrete before each lift below. Avoids sheet pile vibration that damages neighbours.
Road widening at toe of cut
Federal road or expressway lane addition adjacent to existing cut slope. Sequential staged works with traffic management coordination, staged closures, night-shift mobilisation. Live-traffic working method, concrete barrier and hoarding deployment.
Bridge abutment soil nail wall
Permanent bridge abutment retention or toe stabilisation for highway and rail corridor widening. Higher working load (200-400 kN per nail), permanent DCP corrosion protection (double corrosion protection per BS 8006-2 Annex C), concrete panel facing for aesthetic.
