Protect Your Investment with Ireland's Leading Liquid Waterproofing Solutions
When it comes to safeguarding your building against Ireland's unpredictable weather, liquid waterproofing systems deliver unmatched protection and longevity. At QBM, we supply premium liquid-applied membranes that form seamless, durable barriers across flat roofs, balconies, walkways, and gutters. Unlike traditional sheet membranes, liquid systems eliminate joints and seams where water typically finds its way through, creating a completely watertight envelope that moves with your structure.
Our range of liquid waterproofing systems offers versatility that sheet materials simply cannot match. Whether you're working on new construction or refurbishing an existing property, these advanced formulations can be applied directly to various substrates, including concrete, asphalt, metal, and timber. The cold-applied nature of many systems means safer application conditions for contractors, with no naked flames or hot works required. This makes them particularly suitable for occupied buildings, sensitive environments, and projects where health and safety considerations are paramount.
The technical performance of modern liquid waterproofing systems has transformed how the industry approaches roof protection. Products like Ultraflex, Polyroof, and Mariseal Detail provide exceptional resistance to UV degradation, thermal cycling, and standing water whilst maintaining flexibility throughout their service life.
These systems typically cure to form a tough, elastomeric membrane that can accommodate structural movement and thermal expansion without cracking or splitting. Many formulations are also suitable for application in cooler temperatures, extending the working season for Irish contractors beyond the constraints of traditional systems.
One of the most compelling advantages of liquid waterproofing is the speed and efficiency of installation. A competent contractor can apply these systems using standard rollers or spray equipment, dramatically reducing labour time compared to torch-on felt or adhered sheet systems. The ability to achieve a full cure within hours rather than days means buildings can return to service quickly, minimising disruption for occupants. Additionally, the self-levelling properties of liquid membranes ensure consistent coverage across complex details, upstands, and penetrations where traditional materials struggle to achieve proper adhesion.
QBM maintains comprehensive stocks of liquid waterproofing systems from the industry's most trusted manufacturers, backed by technical support and warranty options that give specifiers and contractors complete confidence.
Our Dublin trade counter provides immediate access to materials, whilst our technical team can assist with system selection, coverage calculations, and application guidance. Whether you're a roofing contractor seeking reliable materials for your next project or an architect specifying long-term protection for a commercial development, QBM delivers the products and expertise you need to get waterproofing right the first time.
Got a Question? Find the Answer Here
What surfaces can liquid waterproofing systems be applied to?
Liquid waterproofing systems can be applied to a wide range of substrates, including concrete, asphalt, bitumen felt, metal decking, marine plywood, and existing weathered membranes. The surface must be clean, dry, and properly primed according to the manufacturer's specifications. Different systems are formulated for specific substrates, so it's important to select the appropriate product for your particular roof construction.
How long does liquid waterproofing last compared to traditional felt systems?
High-quality liquid waterproofing systems typically offer superior longevity compared to traditional torch-on felt, with many products carrying 20-25 year warranties when installed correctly. The seamless nature of liquid membranes eliminates the weak points found in sheet systems, whilst modern polymer formulations resist UV degradation and thermal cycling more effectively than older bituminous products. Regular maintenance inspections can extend service life even further.
Can liquid waterproofing systems be applied in cold weather?
Many modern liquid waterproofing formulations are designed for application in temperatures as low as 5°C, making them suitable for year-round installation in Ireland's climate. However, substrate conditions are critical – surfaces must be dry and frost-free. Some systems offer cold-weather variants or accelerated cure options specifically developed for lower temperature applications. Always consult the technical data sheet for specific temperature requirements of your chosen system.
Are liquid waterproofing systems suitable for roofs with foot traffic?
Yes, many liquid waterproofing systems are specifically designed to withstand regular foot traffic and can be specified for balconies, walkways, and accessible roof areas. Some products require a protective wearing course or aggregate finish to enhance slip resistance and abrasion resistance. For areas with intensive foot traffic or vehicular access, specialist heavy-duty systems are available that incorporate reinforcement layers for additional durability.
What maintenance do liquid waterproofing systems require?
Liquid waterproofing systems require minimal maintenance compared to traditional roofing materials. We recommend annual inspections to check for debris accumulation, clear drainage outlets, and inspect joints and upstands. Any minor damage or punctures can typically be repaired using the same liquid membrane material, making maintenance straightforward and cost-effective. Many manufacturers offer maintenance contracts and inspection services to protect warranty coverage and maximise system lifespan.
