Roofing Knowledge for Bandar Sunway
Bandar Sunway mixes high-density residential condos, commercial shoplots along PJS 9 and PJS 11, and university campuses near Monash University Malaysia and Sunway Medical Centre. The dominant roofing challenge here is flat-slab waterproofing — concrete roofs on shoplots and condo blocks that pond water during heavy rain.
Flat-roof ponding is a slow, damaging problem. Water sits and seeps through micro-cracks in the slab, often taking months before the first stain appears on the ceiling below. Our no-hack PU injection approach seals these cracks from within, without demolishing tiles or screeding.
We reach Bandar Sunway from Kota Damansara via LDP. Commercial shoplot inspections are scheduled around your business hours; residential condo work is arranged with building management in advance.

Sunway's commercial and condo roofs
Sunway's shoplots, condo blocks, and education buildings often have flat or low-slope concrete-slab roofs that pond water during heavy rain. PU injection grouting and liquid-applied membranes are the cleanest waterproofing answers here.
What Bandar Sunway customers say
"Our shoplot roof had been ponding for years. They applied a membrane system, fixed the falls, and finally the slab stays dry."
