Complete Facade Protection Systems for Irish Buildings
Ireland's climate creates challenging conditions for buildings. Driving rain, high humidity, and temperature fluctuations lead to water ingress, whilst coastal areas face additional deterioration from salt-laden air. The damage isn't always immediately obvious as moisture can travel through masonry, causing spalling and surface breakdown of concrete and render, corrosion of embedded steel reinforcement, efflorescence and staining, mould growth within wall assemblies, and thermal bridging where insulation becomes saturated. Addressing these issues after they've developed costs significantly more than specifying appropriate protection from the outset, and even retrofit treatments work best when applied before significant damage occurs.
Our range covers most common applications, from straightforward water-repellent treatments to complex structural waterproofing systems. Surface impregnation treatments using silane and siloxane penetrate concrete and masonry substrates, creating water-repellent barriers without blocking vapour transmission—essential for preventing trapped moisture issues. Waterproof coatings and renders form continuous barriers over surfaces, with modern elastomeric coatings capable of bridging hairline cracks and withstanding building movement. For below-ground applications and areas subject to hydrostatic pressure, we supply tanking slurries and membrane systems specifically designed to withstand demanding conditions.
Different facade types require different approaches. Concrete structures need penetrating sealers, anti-carbonation coatings, or crack-bridging systems, depending on age and condition. Rendered surfaces may benefit from water repellent treatments, protective overcoating, or complete renewal with integrated waterproofing systems. Metal facades require proper detailing at joints, fixings, and interfaces, with sealants and weathering components maintaining the weather-tight envelope. Historic and heritage buildings need breathable treatments based on silicate or lime chemistry that maintain vapour permeability, working with the building rather than against it.
Product selection depends on substrate type and condition, exposure conditions, performance requirements, appearance expectations, and maintenance considerations. Even the best products won't perform properly without correct application, surface preparation, weather conditions during application, and proper coverage rates, all of which affect outcomes. Modern facade waterproofing often involves external wall insulation systems where waterproofing forms part of a larger assembly, requiring careful detailing at interfaces, around windows, at corners, and where different materials meet. We stock renders, basecoats, finishing systems, beads, profiles, and sealants needed to complete these junctions properly, including products for critical roof-facade transition zones.

How long does facade waterproofing treatment last?
Durability varies considerably depending on product type, application quality, and exposure conditions. Impregnation treatments typically require renewal every 5–15 years, while coating systems may last 15–25 years before needing attention. Harsh coastal environments or heavily polluted urban areas tend to shorten these intervals. Regular inspections help identify when retreatment is needed before protection is compromised. Manufacturers provide expected service-life guidance, but real-world conditions ultimately determine actual performance.
Can waterproofing be applied to damp walls?
Some products tolerate residual moisture better than others, but most perform best on dry substrates. Applying water-repellent treatments to saturated masonry can trap moisture within the wall, potentially causing more severe problems than leaving it untreated. Where existing damp issues are present, it's generally advisable to identify and address the moisture source first. Certain breathable systems can be applied to walls that aren't fully dry, though this should be discussed with the product manufacturer.
What's the difference between water repellent and waterproof treatments?
Water-repellent treatments cause water to bead on surfaces rather than be absorbed, but they don't create a continuous barrier. They're breathable and maintain the substrate's appearance. Waterproof treatments form an impermeable film that blocks moisture movement, making them appropriate for below-ground use but potentially problematic on facades, where trapped moisture needs to escape. The distinction matters particularly for older buildings with solid walls, where breathability is often essential for long-term building health.
Do waterproofing treatments affect the appearance of facades?
It depends on the product. Penetrating sealers and impregnation treatments are typically designed to be invisible once cured, though they may slightly darken some substrates. Coating systems obviously change appearance, that's partly the point, and are available in various colours and textures. If maintaining the original appearance is important, test patches in inconspicuous areas to confirm the expected finish before committing to the full application.
