How Much Does Waterproofing Membrane Removal Cost?
The cost to remove a waterproofing membrane typically ranges from $10 to $60 per square metre, depending on the membrane type, the level of preparation required, and the finish you want achieved once the coating is removed. Every project is unique, and pricing can vary based on several key factors.
Below is a clearer breakdown of what can influence the final cost:
TYPE OF COATING OR MEMBRANE:
Different waterproofing systems require different removal methods. Some coatings, such as epoxy or polyurethane, are extremely hard-bonded and take significantly more time and labour to remove than lighter acrylic or rubber membranes.
SIZE OF THE AREA:
Smaller jobs often carry a higher per-square-metre rate because setup, protection, and dust-control requirements remain the same regardless of area size. Larger projects benefit from reduced pricing due to efficiency.
CONDITION OF THE EXISITING SURFACE:
If the concrete is damaged, uneven, or contaminated with adhesives, paint, or multiple membrane layers, additional preparation will be required—impacting the overall cost.
REQUIRED SURFACE FINISH:
If the membrane needs to be removed in a way that prepares the slab for a specific finish (such as polished concrete, exposed aggregate, honed concrete, or a high-bond waterproofing re-application), the process becomes more meticulous and may increase pricing.
ACCESSABILITY OF THE WORK AREA:
Tight, restricted, or elevated spaces often require specialised equipment, additional labour, or slower removal processes—contributing to higher costs.
How Long Does Waterproofing Membrane Installation Take?
Installing a high-quality waterproofing membrane generally takes anywhere from 4 hours to 2 days, depending on the size of the area, the level of preparation required, and the number of coats needed to meet Australian standards.
Liquid-applied membranes must be applied methodically and allowed to cure between stages to ensure long-lasting waterproof protection. Below is a clear and practical breakdown of typical installation timeframes:
Small Areas: 4 – 12 Hours:
Perfect for bathrooms, balconies, laundries, ensuites, and other internal wet areas. These spaces typically require light surface preparation, followed by a primer coat and two layers of liquid waterproofing membrane. Adequate curing time between each coat is essential to achieve a seamless and durable finish.
Medium Areas: Approximately 1 Day:
This category includes planter boxes, rooftop sections, podiums, and medium-sized commercial surfaces. These areas usually require additional preparation work and a more robust membrane application. The larger surface area and increased drying time naturally extend the overall installation period.
Large or Complex Areas: 1 – 2 Days:
Bigger projects—such as full rooftops, retaining walls, external facades, or multi-level structures—often require more extensive preparation, high-build membrane systems, and multiple coats. Longer curing times are essential to ensure the membrane forms a strong, flexible, and watertight barrier capable of withstanding long-term exposure.
Can Waterproofing Membranes Really Be Removed Dust-Free?
Yes, they absolutely can. Our team uses advanced HEPA-rated dust extraction systems capable of capturing up to 99.99% of fine concrete dust particles* during membrane removal. This ensures a significantly cleaner, safer, and healthier work environment for both our clients and our technicians.
Unlike many contractors who rely on basic or outdated dust-control methods, we use industrial-grade, fully integrated vacuum systems that connect directly to our grinding and stripping equipment. This allows us to remove even the most stubborn waterproofing membranes while keeping airborne dust to an absolute minimum.
If you want a clean, efficient, dust-controlled membrane removal service, we deliver industry-leading results every time.
Different Types Of Waterproofing Membranes That We Can Remove
We specialise in the safe, efficient, and professional removal of all major waterproofing membrane systems used across residential, commercial, and industrial properties. Our team is equipped with advanced tools and industry-leading techniques to ensure every membrane is removed cleanly, allowing your surface to be fully prepared for new waterproofing, repairs, or renovation work.
Below are the common membrane types we expertly remove:
– Epoxy Membranes
– Hybrid Membranes
– Acrylic Membranes
– Rubber Membranes
– Bituminous Membranes
– Cementitious Membranes
– Polyurethane Membranes
– Liquid-Applied Membranes
– Synthetic Sheet Membranes
– Bituminous (Asphalt-Based) Sheet Membranes
We are also fully capable of removing any other waterproofing membrane type, regardless of how old, degraded, or heavily bonded it may be. Every membrane requires its own method of extraction, and our experienced technicians understand exactly how to carry out each removal with precision, safety, and minimal disruption.
Why Timely Waterproofing Membrane Removal Is Essential
Putting off the removal of a failing or deteriorated waterproofing membrane can lead to serious, costly, and often irreversible damage. Once a membrane stops performing as designed, moisture can begin penetrating the structure—triggering a range of issues that escalate quickly.
Here’s why prompt removal is critical:
Water Damage & Structural Deterioration:
A compromised membrane allows water to seep into the concrete, creating the perfect conditions for Concrete Cancer, corrosion, and internal structural breakdown. The longer the moisture remains, the more extensive the damage becomes.
Mould & Bacterial Growth:
Moisture trapped beneath a failing membrane encourages rapid mould development, which can spread through surrounding areas and pose significant health risks to occupants.
Higher Repair & Restoration Costs:
Delaying membrane removal often results in far more expensive repairs. Water damage compounds over time—meaning what could have been a simple replacement can eventually require major structural remediation.
Taking action early protects your building, minimises downtime, reduces long-term costs, and ensures the safety and durability of your property.
Do We Remove Rooftop Waterproofing Membranes Also?
Yes, we absolutely do. Our team is fully equipped to safely remove rooftop waterproofing membranes on residential, commercial, and industrial buildings. Whether the membrane is peeling, failing, holds trapped moisture, or needs to be replaced for a new roofing system, we can complete the removal efficiently and with full dust-control measures in place.
Rooftop membrane removal often requires specialised equipment, height-safe systems, and precise handling to avoid damaging the underlying structure. Our technicians follow strict safety protocols and industry standards to ensure the process is completed cleanly, safely, and without disruption to your property.
If your rooftop waterproofing system is deteriorating or due for replacement, we can prepare the surface properly so new waterproofing can be installed to the highest standard.
