Car porch slab, torch-on membrane.Our own work.

We seal rooftop slabs, car porch slabs, balconies and terraces with torch-on membrane — heat-fused sheet by sheet into one continuous surface, made to take the Malaysian sun as well as the rain. The inspection is free. The quotation is free.

What we fix

What we waterproof

Roofing and waterproofing for rooftop slabs and car porch slabs is what we do most. We also waterproof balconies, terraces and foundations, and for commercial buildings, basements, roofs and exterior walls.

  • A finished dark membrane roof deck on a house, bounded by a low parapet, with neighbouring tiled roofs behind.

    Rooftop slab

    Flat concrete roofs on houses, apartments and commercial buildings. Torch-on membrane laid across the whole slab as one continuous surface.

  • A lit gas torch heating a roll of membrane on a roof.

    Car porch slab

    The slab over the car porch takes sun all day and rain all year. We waterproof it with the same torch-on system.

  • A finished dark membrane balcony beside a metal railing.

    Balcony and terrace

    Balconies, terraces and upper-floor walkways kept leak-free with the same durable membrane.

  • A dark membrane deck meeting a red clay tiled roof.

    Roof leak repair

    A leak that returns every rainy season. We solve it long term rather than patching it for the next one.

  • Foundation

    Foundations secured against water infiltration, for long-term stability.

  • Basement and exterior wall

    For commercial properties: basements, roofs and exterior walls protected from leaks, seepage and structural damage.

Residential: landed houses, apartments and condominiums. Commercial: shopping malls, airport retail units, schools, offices and institutional buildings.

How it works

Heat-fused sheet by sheet. One surface, no joints for water to find.

Torch-on bituminous membrane is the system we use most. Each sheet is heated with a gas torch and fused to the surface and to the sheet before it, so the finished roof is one continuous layer with a strong bond. It has high resistance to heat and ageing, which is why it is used on flat roofs and areas exposed to direct sunlight.

    Membrane is delivered in rolls

    The rolls are staged across the slab before the first sheet is laid.

  2. Torched and fused

Questions we're asked

What waterproofing system do you use?

Torch-on bituminous membrane. Each sheet is heated with a gas torch and fused to the surface and to the sheet before it, so the finished roof is one continuous layer. It has high resistance to UV, heat and ageing, which is why it is used on flat roofs and areas exposed to direct sunlight.

Which parts of a building do you waterproof?

Rooftop slabs, car porch slabs, balconies and terraces, and foundations. For commercial buildings we also waterproof basements, roofs and exterior walls.

Do you work on houses as well as commercial buildings?

Both. Residential work runs from landed houses to apartments and condominiums. Commercial work includes shopping malls, airport retail units, schools and offices.
