How Do You Fix a Leaking Concrete Floor?

If the leak is caused by a small fracture or minor crack, it can be cured with a membrane or epoxy resin applied to the outside of the foundation into the cracks. The waterproofing operation will then precisely target the area to be treated. If the foundation walls have more serious flaws or flaws, the whole waterproofing may need to be reviewed and possibly replaced.

How To Handle Leakage From Upper Floor

If your flooring is damaged, you may need to replace your flooring tiles. You have to also ensure that waterproofing be done with the flooring tiles installation. If you notice a damp spot that persists off and on on the ceiling, there's a 99 percent chance the drain pipe is leaking. You may need to get your pipe checked and repaired. If your neighbour's flooring is the issue and is affecting your ceiling, then other than checking on your ceiling, your neighbour may need to get their flooring fixed as well.

About Torch-On Membrane Waterproofing

Torch-on membrane waterproofing remains one of the most reliable and long-lasting systems for exposed and concealed areas. At Waffen Waterproofing, we provide professional torch-on membrane installation using high-quality bituminous sheets designed for Singapore’s weather and building conditions.

Torch-on waterproofing uses bituminous membrane sheets that are heated with a torch to form a heat-fused, fully bonded waterproof layer. The high temperature melts the underside of the membrane, allowing it to bond tightly to the substrate, creating a tough, durable barrier against water infiltration.

Why Torch-On Membrane is Popular in Singapore

Highly durable in hot and wet climates
Excellent UV and weather resistance (especially APP membranes)
Can be applied on large roof surfaces
Mechanical strength to withstand foot traffic (for thicker membranes)
Suitable for both new construction and re-roofing works

Types of Torch-On Membrane

SBS Modified Bitumen Membrane – flexible, great for concealed areas and surfaces with movement
APP Modified Bitumen Membrane – UV-resistant, ideal for exposed roofs and terraces
Single-layer or double-layer systems depending on project requirements

Frequently Asked Questions (FAQs)
Torch-On Membrane Waterproofing in Singapore

How long does torch-on membrane last?

Typically, a torch-on membrane system can be expected to last between 10 to 20 years.

The precise lifespan is influenced by several factors, including the level of environmental exposure it faces, such as harsh weather conditions or prolonged UV radiation, and the diligence of its ongoing maintenance.

Can I walk on the membrane?

Yes, but only after the surface has fully cooled to avoid any potential damage or uneven wear. For areas with regular foot traffic, it’s highly advisable to apply a protective screed.

Is it suitable for metal roofs?

Torch-on membranes are typically used on concrete substrates.

For metal roofs, alternative waterproofing systems are preferred because metal expands and contracts with temperature changes. These moveme

Can torch-on membrane be applied over tiles?

No, you cannot apply a torch-on membrane directly over tiles.

For the membrane to bond correctly and create an effective waterproof seal, the tiles must be removed first. The underlying surface needs to be completely flat, smooth, and clean to ensure proper adhesion.
