Work on Malaysia's soft ground.

KM 48.7–48.85 eastbound, Pahang

Pavement defects: shallow PU injection

Geotechnical assessment and injection works for a depressed pavement section. Probe tests before and after injection showed the sub-grade re-strengthened.

Pulau Indah Expressway (Phase 2), Selangor

Bridge abutment rehabilitation

Void filling under the approach slab, PU injection beneath the piled embankment slab, and ground stabilisation at the transition zone, with settlement monitoring afterwards.

Kuantan, Pahang

Soil settlement: engineering, procurement and construction

Soil settlement remediation at a plant area on very soft sandy silt. Laboratory tests on treated samples showed higher undrained shear strength and stiffness.

Johor

Void and cavity stabilisation at a transition zone

Stabilisation of voids between a piled embankment slab and the embankment fill. Plate loading tests after injection recorded bearing pressures above the design criteria.

South Klang Valley Expressway, Selangor

Bridge abutment rehabilitation

Inspection below the abutment, PU void filling and plugging, and injection works, with settlement monitoring.

Bridge approach and Sg Gulang-Gulang culvert approach, Selangor

Ground rehabilitation research works

Alternative ground rehabilitation using PU foam injection at a bridge approach and a culvert approach, carried out as research with JKR, with settlement monitoring.
