Wet Area Waterproofing

Water Leakage Repair Pros at Your Service

Dealing with constant water leakages in common wet areas in your home?


The constant use of water in these spaces, with moisture penetrating through floors or walls, can make them prone to vulnerabilities, especially at weak points like wall joints, cistern and pipe connections, and corroded piping materials.


What’s worse, water damage doesn’t only stop with peeling paint or a leaking toilet, but it can also creep to adjacent rooms and cause toxic mould to develop.


Prevent these issues with Allstar Waterproofing’s specialised waterproofing systems!


From swimming pools to balconies, toilets, bathrooms, and kitchens, we can address all your water leakages and effectively safeguard your spaces.

As Featured In

Common Causes of Wet Area Waterproofing Failures

ceiling drop off due to wet cement

Water leakage at pipe penetration and joints

Insufficient sealing at structural joints allows water seepage, jeopardising the overall integrity of the waterproofing system.

Cracks in tiles

Cracks in tiles, whether from structural movement or installation issues, serve as entry points for water and pose a threat to the effectiveness of the waterproofing system.

Water leakage through porous concrete

Concrete is inherently porous. Without proper waterproofing, concrete surfaces become vulnerable to water infiltration, posing a risk to the overall effectiveness of the system.

Tile de-bonding

When tiles aren’t adequately bonded to the substrate, de-bonding occurs, facilitating water penetration beneath the surface and undermining the effectiveness of the waterproofing.

Rust staining

Rust staining is indicative of water leakage and corrosion of metal components.

Poor workmanship

Poor preparation

Inadequate surface preparation, such as insufficient surface cleaning or improper priming, can hinder the proper adhesion of the waterproofing membrane, making it susceptible to tears, cracks, and water penetration.


Poor application of waterproofing membrane

Failure to apply the waterproofing membrane according to manufacturer recommendations or by extending it beyond the wet area requirements can compromise its effectiveness.


Use of cheap waterproofing products

Opting for low-quality waterproofing materials may cost less initially but can result in premature failure and lead to more expensive damages down the road.

The Allstar Promise: Wet Area Waterproofing Solutions Tailored to Your Needs

Embrace the Allstar Waterproofing difference, where our unwavering precision in wet area waterproofing ensures only the correct waterproofing techniques and materials will be used for the specific problem at hand.


Here are some of the methods we use to address your wet area waterproofing issues:

Complete NON-HACKING Wet Area Waterproofing Treatment

Flood Infusion Treatment (Crystallisation Waterproofing Treatment)

Our flood infusion method offers a unique approach to waterproofing, harnessing crystalline waterproofing technology.

This technique utilises the power of crystalline compounds or needle-like crystals within the concrete to effectively penetrate concrete pores and capillaries, forming a self-sealing barrier against water penetration.

The outcome is watertight concrete structures without the need for invasive construction work.

Nano Coating by Allstar Waterproofing & Services

Nano Technology Coating

Nano Technology Coating works by making almost any substrate surface water-repellent.

By leveraging nanoparticles, this liquid-applied coating deeply penetrates pores and capillaries without causing blockages. Treated surfaces maintain breathability, ensuring a lasting and effective water-repellent barrier.

Installation of a NEW Waterproofing System

If your water leakage problem cannot be managed with waterproofing membrane coatings, you may need to strip out a whole wet area and install a new waterproofing system.

Commonly used when waterproofing toilets and bathroom floor tiles, this method involves applying a physical barrier to the floors and walls to prevent water penetration and protect the walls and subfloor.


Here’s a brief overview of our process:


Surface Preparation: Strip and clean, returning the area to its original state, free of debris.


Priming: Prime rough surfaces, creating an ideal foundation for waterproofing.


Fillets and Bond Breakers: Seal junctions and edges for enhanced protection against water.


Application: Apply a flexible cementitious membrane with a hydrophobic screed layer to prevent water, vapour, and moisture penetration into concrete surfaces.


Inspection: Conduct thorough inspections during all application phases for quality assurance.


Waterproofing Ponding Test: Check how well the waterproofing method works through the ponding test.


This involves applying water to a surface to see if the waterproofing can effectively prevent water penetration and successfully keep things dry, especially in places where water might collect.
