Aliphatic Polyurethane (PU) is the gold standard for roof waterproofing in the UAE climate. UV-stable, seamless, and flexible enough to handle Dubai's extreme thermal cycling. Built to last 10–15 years.
Not all waterproofing membranes are equal in the UAE climate. Bitumen degrades under UV. Acrylic paints peel off. Only Aliphatic Polyurethane (PU) combines the three properties that matter most in Dubai: UV stability, thermal flexibility, and a seamless bond to concrete or metal substrates.
Aliphatic PU does not yellow or chalk under the intense Gulf sun. It remains flexible at elongations above 90% — meaning it flexes with the roof as it expands and contracts through the 60°C daily temperature swings. And because it is applied as a liquid, it forms a single seamless membrane with no joints, laps, or seams — the points where all other waterproofing systems eventually fail.
Available in white (high SRI cool roof coating) or grey, a PU system also significantly reduces interior temperatures by reflecting solar heat — with clients reporting AC bill savings of 15–25%.
Moisture mapping, crack identification, and surface contamination check before any application.
Pressure washing, mechanical grinding of loose material, and crack filling with PU sealant.
Penetrating epoxy or PU primer applied to ensure chemical adhesion to the substrate.
High-build PU membrane applied at 1mm wet film thickness. Reinforcement fleece embedded at joints and details.
Second membrane coat applied after curing. UV-resistant aliphatic topcoat applied for long-term colour and UV stability.
UV-stable, seamless, 90%+ elongation. Suitable for flat concrete roofs, terraces, and balconies. 10-year warranty available.
High SRI white reflective topcoat. Reflects up to 85% solar radiation. Reduces interior roof surface temperature by up to 20°C.
Additional fibre reinforcement layer for high-traffic rooftops, expansion joints, and large industrial slabs subject to movement.
Full PU system with primer, 2 coats, and warranty. Based on area and condition.
Includes reflective aliphatic topcoat. Recommended for villas and warehouses.
For large industrial slabs, expansion joints, and high-movement areas.
Typical all-in price for a 3–4 bedroom villa flat roof. Free quote provided.
Aliphatic Polyurethane (PU) is a two-component liquid waterproofing membrane that cures to form a seamless, flexible, UV-stable rubber layer on the roof surface. It is the preferred system for Dubai roofs due to its resistance to the extreme UAE climate.
Applied professionally, an Aliphatic PU system lasts 10–15 years in the UAE. Dubai Roof Seal provides a written warranty of 5 or 10 years on all PU waterproofing projects.
Yes, in virtually every measurable way for UAE conditions. PU is UV-stable (bitumen cracks within 3–5 years), seamless (bitumen has laps and joints), flexible (bitumen becomes brittle), and available in white for solar reflectivity (bitumen is black and absorbs heat).
In most cases, yes — provided the existing system is sound and well-bonded. We conduct an adhesion test during the free inspection to confirm compatibility.
Yes. A white aliphatic PU topcoat with a high Solar Reflectance Index (SRI) can reduce roof surface temperatures by up to 20°C compared to a dark bitumen surface. Many of our commercial clients report energy savings of 15–25% after application.
Free site inspection. Fixed written quote. 10-year warranty on all PU systems. Covering all Dubai areas — 7 days a week.
