Air Selangor<\/div> <\/div>
<\/i><\/div><\/div>

Location<\/h3><\/div>
Selangor, Malaysia<\/div> <\/div>
<\/i><\/div><\/div>

Product Grade<\/h3><\/div>
NovaTex NW10 Non-Woven Geotextile<\/div> <\/div>
<\/i><\/div><\/div>

Quantity Supplied<\/h3><\/div>
250,000 m2<\/sup><\/div> <\/div>
<\/i><\/div><\/div>

Primary Application<\/h3><\/div>
Non-woven geotextile as separator for drainage blanket<\/div> <\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

The Challenges Provided<\/h2>\r\n\t
\r\n\t\t
\r\n\t\t\t

The development of the Sg. Rasau Water Treatment Plant and intake infrastructure required extensive earthworks and ground treatment over soft subgrade conditions typical of alluvial floodplains.<\/p>\n

During the installation of drainage blankets across large footprint areas:<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

<\/i><\/div><\/div>

Intermixing of Aggregates<\/h3><\/div>
Heavy construction equipment and earthmoving machinery risks driving the structural granular drainage aggregate into the underlying soft subgrade soil, causing contamination and loss of sub-base thickness.<\/div> <\/div><\/div><\/div><\/div><\/div>
<\/i><\/div><\/div>

Loss of Hydraulic Efficiency<\/h3><\/div>
Migration of fine soil particles into the aggregate drainage layer threatens to clog flow paths, disrupting pore water pressure dissipation and weakening long-term subgrade stability.<\/div> <\/div><\/div><\/div><\/div><\/div>
<\/i><\/div><\/div>

Large Surface Coverage<\/h3><\/div>
The massive scale of earthworks required a reliable, cost-effective, high-volume geotextile solution that could withstand high installation stress without tearing.<\/div> <\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>

The Solution<\/h2>\r\n\t
\r\n\t\t
\r\n\t\t\t

To maintain the structural and hydraulic integrity of the drainage blanket across 250,000 m2<\/sup>, NovaTex NW10 non-woven geotextile<\/strong> was selected as the separator layer.<\/p>\n\r\n\t\t<\/div>\r\n\t<\/div>\r\n

Effective Separation Layer<\/h3>

1<\/p><\/div>

NovaTex NW10 was laid directly over the prepared subgrade prior to aggregate placement, creating a high-strength physical barrier that prevents the intermixing of fine subgrade soil and coarse drainage stone.<\/div> <\/div><\/div>

Optimal Permeability & Filtration<\/h3>

2<\/p><\/div>

Engineered with needle-punched synthetic fibers, NovaTex NW10 maintains continuous three-dimensional water flow into the drainage blanket while retaining soil fines, keeping the drainage layer clean and unclogged.<\/div> <\/div><\/div>

Robust Mechanical Strength<\/h3>

3<\/p><\/div>

The high tensile strength and puncture resistance of NovaTex NW10 provided superior cushioning against heavy machinery traffic (such as tractors and bulldozers) during backfilling and compaction.<\/div> <\/div><\/div><\/div><\/div><\/div><\/div>
\r\n\t
\r\n\t\t\t\r\n\t\t\t
\"\"<\/div>\r\n\t\t<\/div>\r\n\t<\/div>\r\n<\/div><\/div><\/div><\/div><\/div>

The Result<\/h2>
<\/i><\/div><\/div>

Preserved Layer Integrity<\/h3><\/div>
Successfully prevented subgrade intermixing, ensuring 100% efficiency of the drainage blanket layer across the entire construction site.<\/div> <\/div><\/div><\/div><\/div><\/div>
<\/i><\/div><\/div>

Optimized Construction Efficiency<\/h3><\/div>
High material flexibility and ease of roll placement allowed rapid site installation, keeping the large-scale earthworks on schedule.<\/div> <\/div><\/div><\/div><\/div><\/div>
<\/i><\/div><\/div>

Long-Term Performance<\/h3><\/div>
Ensured long-term pore pressure reduction and ground stabilization beneath key water treatment plant infrastructure.<\/div> <\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>
