Although concrete is strong, it is not completely waterproof. Moisture can enter through pores, cracks, joints and other vulnerable areas. Over time, water penetration may contribute to deterioration and corrosion of embedded steel reinforcement. Waterproof concrete surfaces can help reduce water ingress when the appropriate system is selected and installed correctly. Concrete waterproofing is particularly important for exposed areas that regularly experience rain, washing or other water exposure. Before selecting a waterproofing solution, assess the concrete for cracks, damaged joints, surface deterioration and drainage problems. These issues should be addressed according to the relevant repair and installation requirements before applying a membrane.
A concrete waterproofing membrane creates a protective layer over a suitable prepared surface. Remedial Membranes’ Clear Waterproofing Membrane is designed to help protect concrete while retaining its natural visual appearance. Unlike an opaque coating, a clear waterproofing membrane allows the underlying concrete finish to remain visible. Available finish options include gloss, satin and matte, subject to the product and application requirements.
The membrane may be suitable for selected concrete surfaces exposed to rain, shower water or water from a hose. Suitability depends on the substrate, surface preparation, application method and product specifications. A clear membrane is not a universal solution for every concrete waterproofing problem. It should not be used as a substitute for repairing serious structural defects or addressing rising damp and persistent ponding water.
Different concrete surfaces have different waterproofing requirements. Choosing a suitable solution starts with understanding where the water comes from and how the surface is constructed.
Waterproofing concrete floors can help protect suitable surfaces exposed to routine water contact and make them easier to maintain. For polished concrete or other decorative finishes, check compatibility before applying a waterproofing product, as the treatment may affect the appearance, texture or slip resistance.
When considering waterproofing an existing concrete slab, inspect the surface for cracks, movement, deterioration and moisture issues. A surface-applied membrane may be suitable for certain exposed slabs, but it is not the same as an under-slab waterproofing membrane installed beneath concrete before construction. If your project requires under-slab waterproofing, below-ground protection or resistance to water pressure from behind the membrane, obtain advice on a system designed specifically for those conditions.
Concrete balconies, patios and exposed concrete roof surfaces can experience repeated exposure to rain and changing weather conditions. A compatible membrane may help protect suitable surfaces from water ingress while preserving the appearance of the concrete. Correct drainage and surface falls are essential. The Clear Waterproofing Membrane is not intended for areas where water remains ponded, so confirm suitability before using it on a roof slab or other exposed horizontal surface.
Successful concrete waterproofing depends on proper preparation and application. The general process for a suitable surface includes:
Concrete is often porous, so the preparation and sealing process may differ from that used on tiles or other substrates. Always follow the current product-specific installation guide rather than assuming that one application method suits every surface.
Remedial Membranes specialises in clear waterproofing membrane solutions for suitable existing surfaces. The system is designed for applications where retaining the appearance of concrete is important. Product resources include installation guidance, application videos and technical support to help customers understand the correct preparation and application process. Customers who prefer professional assistance can also explore the available accredited installer options. Whether you are considering waterproofing concrete floors, protecting a concrete balcony or treating an exposed concrete facade, review the product specifications and installation requirements before deciding on the appropriate system.
No. Concrete can resist water to some extent, but its porous structure may allow moisture to penetrate through the surface, cracks and joints.
The appropriate method depends on the application. Some exposed concrete surfaces may be suitable for a surface-applied waterproofing membrane, while below-ground structures and under-slab applications may require different systems.
Some polished concrete surfaces may be suitable for compatible protective treatments. Check the product specifications and test the proposed finish, as the application may change the surface appearance or slip characteristics.
Yes, some existing slabs may be suitable for surface-applied waterproofing. The condition, moisture level, drainage and intended use must be assessed first.
Like 95% of other waterproof membrane Clear Waterproofing Membrane is a positive membrane which protect the surface from the rain and the hose but not from rising damp. Rising damp is usually a requirement of preventing water sitting against porous building materials. In areas where that is not possible you should be looking for using epoxy
No, Clear Waterproofing Membrane will blush or appear milky in ponding water over time so we recommend that it is only installed on surfaces with fall.
External areas are generally subject to UV and as such are not really subject to too many issues with mold.
There are reduced pores for dirt to sit in so it will be easier to clean a clean once a week with white vinegar will be sufficient.

“Thank you to Jasmine of Remedial Membranes for her work in rectifying the leak caused by the gradual wearing of the waterproofing in our bathroom. The application of the membrane has saved us a huge headache and thousands of dollars! We highly recommend this form of waterproofing.”
“I recently had a failed waterproofing membrane under a tiled balcony. This resulted in substantial leakage and major damage to my ceiling…A clear waterproofing membrane from Remedial membranes was applied over the existing tiles. I found them professional, on time, and did an excellent job. Our balcony has not leaked despite substantial rain since the repair.”
“Great Business to deal with. Keep you updated and in the picture. Had no issues at all. Great product – does the job and finish is good. We had our steps and front Patio done. Impressive ! Would recommend product & Supplier with no hesitation.”
“I contacted Remedial Membranes after we sold our house but one of the conditions of the sale was the showers to be repaired. We didn’t have any spare tiles and the new owners did not want the look to change so the idea of putting a clear membrane over the surface was a perfect solution to everyone involved. The job was done in 1 morning and the sale went through. Highly recommend Remedial Membranes. Their ability to work to a deadline was fundamental for the success!”
Why do balconies start to leak?
Most leaks develop, when the substrate moves. Initially, most balconies are built using a foil membrane under their tile or concrete surface, and it is not possible to access it for repair without removing the surface material.
Especially timber frame constructions, but other substrates too, are subject to small movements due to temperate, moisture or soil changes around your house. Flexible membranes are able to withstand these movements.
With a clear membrane installed on top, it’s easier to identify leaks and to patch repair. It’s estimated that the cost of DIY installation of our Clear Waterproofing Membrane costs LESS THAN 10% of what it would cost to replace a damaged membrane under tiles!
