Common Areas for Water Leakage


As the waterproofing membrane and screed in your floor slab undergo the natural wear and tear journey, they might pave the way for an unwelcome guest – cracks.


And when these uninvited cracks make room for water from above to sneak into your ceiling, you’ve got yourself a leakage problem.


Now, a water leak on the ceiling is not just a minor inconvenience; it’s a double trouble package – a threat to both your well-being and safety.

Imagine this: mould creeping in, causing not just respiratory issues but turning your space into a health hazard zone. But that’s not all; water mingling with electrical fittings is a safety tango you definitely want to avoid!

Water Leakage Repair by Allstar Waterproofing & Services

If you overlook the signs, water seepage and leakage on your walls can wreak havoc on your prized possessions – from foundation walls to plasterboard walls and even the flooring.

Left unattended, this stealthy intruder, hidden within your walls, creates a damp haven that not only fosters mould but also poses a serious health and safety threat to you and your loved ones.But fear not, here are 10 clues to stay one step ahead and spot the sneaky water trouble behind your walls:
  • Unpleasant Odors
  • Mould Growth
  • Stains
  • Peeling or Bubbling Surfaces
  • Warping
  • Buckled Flooring
  • Damp or Wet Spots
  • Discolouration
  • Wet Floors
  • Mysterious Dripping Sounds


Swift action is crucial when you spot a stain on your ceiling or witness water dripping from a bulge. Addressing these issues promptly can prevent a manageable concern from escalating into a costly and extensive repair.


Beyond the immediate inconvenience, water leakage on the roof might be an indication of a more significant problem, potentially leading to danger and increased structural erosion if left unattended.


To stay ahead of potential issues, we strongly recommend conducting a roof inspection at least twice a year.

You can perform a self-check, keeping an eye out for any visible signs of damage, or opt for the expertise of a professional roof contractor to ensure a thorough and reliable inspection.

The Allstar Promise: Wall Leakage Solutions Tailored to Your Needs

Embrace the Allstar Waterproofing difference, where our unwavering precision in water leakage repair ensures only the correct roof, interior and exterior wall waterproofing techniques and materials will be used for the specific problem at hand.


Here are some of the methods we use to address your water leakage problems:

PU Injection by Allstar Waterproofing & Services

Polyurethane (PU) Injection

Commonly known as Grouting, PU Injection is an effective method for repairing water seepage and leakage. This technique involves pressuring a chemical into the affected areas and is widely used for addressing cracks in concrete and honeycombed concrete.

Upon contact with water, the polyurethane (PU) chemical reacts and expands, foaming up to seal concrete pores and cracks. Notably, PU’s expansion capability can be up to 20 times the injected volume.

Flood Infusion Treatment by Allstar Waterproofing & Services

Flood Infusion Treatment (Crystallisation Waterproofing Treatment)

This unique treatment offers superior waterproofing without the need for disruptive hacking or intrusive procedures. Utilising a crystalline waterproofing technology, the flood infusion technique enables concrete to self-seal through the development of needle-like crystals.

These crystals penetrate concrete pores and capillaries, effectively sealing and blocking water penetration, resulting in watertight concrete structures.

Nano Coating by Allstar Waterproofing & Services

Nano Technology Coating

Utilising a liquid-applied coating, Nano Technology Coating imparts water-repellent properties to almost any substrate surface. Operating on a nanoscale, the technology allows nanoparticles to deeply penetrate pores or capillaries without obstructing the substrate.


The results? Treated surfaces remain breathable while benefiting from enhanced water repellency.

Water Seepage

Waterproofing Coating

For refurbishing roof and external wall surfaces, the waterproofing coating process ensures thorough patching and sealing of all cracks.


A protective waterproof coating is also applied to existing roofs and external walls, serving as a safeguard against the detrimental effects of water damage and moisture buildup.
