Residential Development In Gamuda Land, Kundang

An accelerated ground consolidation initiative ensuring long-term structural stability and expedited construction timelines for master-planned residential infrastructure over challenging soft clay subgrades.

Location

Kundang, Selangor, Malaysia

Product Grade

NovaDrain ND403 Prefabricated Vertical Drains (PVD)

Quantity Supplied

30,000 m (linear meters)

Primary Application

Accelerated Soft Foundation Consolidation

The Challenges Faced

The residential site in Kundang was located on low-permeability, saturated soft clay layers, presenting critical soil consolidation challenges prior to building works:

Slow Natural Consolidation

Natural drainage through dense clay strata would take years or decades under surcharge loads, causing severe delays to the master development program.

Risk of Post-Construction Settlement

Building permanent residential foundations and access roads directly over un-consolidated clay risks long-term settlement, pavement cracking, and structural instability.

High Pore Water Pressure

Surcharge placement without rapid water dissipation risks triggering shear failure in soft clay layers due to elevated excess pore water pressure.

The Solution

To drastically shorten soil consolidation time across the project area, NovaDrain ND403 prefabricated vertical drains (PVD) were installed vertically into the soft clay subgrade using specialized stitcher rigs.

Shortened Drainage Paths

1

NovaDrain ND403 creates vertical high-permeability escape channels, transforming long vertical water drainage paths through thick clay into short horizontal distances toward the nearest drain.

Efficient Hydraulic Core & Non-Woven Filter

2

Formed with a corrugated polypropylene core surrounded by a non-woven geotextile filter jacket, NovaDrain ND403 rapidly discharges water while filtering out fine clay particles to prevent clogging.

Accelerated Settlement

3

Working in combination with surcharge fill, the PVD system allowed controlled, rapid release of pore water, achieving primary soil settlement within months instead of years.
