Waterproofing Is Not an Option, It Is a Necessity in Qatar’s Climate
Waterproofing in Qatar
Qatar’s construction market is one of the most active and technically demanding markets in the world. Buildings here are subject to environmental conditions that accelerate the decay of structures faster than almost anywhere else on the planet, from high-rise towers in Lusail to infrastructure projects throughout Doha.
Without a properly specified and professionally applied waterproofing system, the climate of Qatar will find the weak point of any structure and the cost of repair will always be far greater than the original waterproofing job.
Compass Waterproofing has been working in Qatar long enough to know what systems work in these conditions and what systems don’t. We design each solution from real field experience not from a product catalogue
Extreme Heat
Summer temperatures above 50°C cause severe expansion and contraction of roof membranes, concrete slabs and joint sealants, accelerating the failure of underspecified systems.
Intense UV Radiation
One of the highest UV indexes in the world is in Qatar. Unprotected membranes, acrylic coatings and sealants will show a significant degradation in one summer without UV-rated protection.
Coastal Humidity & Salt
Doha’s coastal location means that airborne salt and high humidity can penetrate concrete and attack steel reinforcement – causing corrosion and structural damage from the inside out.
Flash Flooding
Every weakness in a flat roof is immediately revealed with heavy summer rains in Qatar. Poor drainage and broken membranes can cause internal flooding that can do great damage in a matter of hours.
Our Services
Our Waterproofing Services In GCC
Crack Injection
Cracks in concrete provide a highway for water to reach the steel reinforcement inside your structure. We inject high performance epoxy or polyurethane resin under controlled pressure sealing every crack completely from the inside stopping water infiltration and protecting your building’s structural integrity across Qatar, UAE and Saudi Arabia.
Roof Waterproofing
Rooftops in the GCC are exposed to the world’s harshest UV radiation, temperatures over 50°C and continuous thermal stress. We apply seamless WetSuit® spray membranes, HarcoSil silicone coatings and reflective acrylic systems to form a durable, watertight barrier protecting your building from water damage and reducing indoor heat simultaneously.
Water Proofing – Liquid Membrane
Liquid membrane waterproofing cures to form a seamless, fully bonded waterproof layer that has no joints or weak points. The WetSuit® 2 PART instant-set spray system sets in seconds of application, making it ideal for large roofs, podium decks, basements and infrastructure projects throughout the GCC where speed and seamlessness are both critical.
Epoxy Flooring
Forklifts, chemical spills, heavy traffic and extreme temperatures are all daily challenges for industrial and commercial floors in the GCC. Our epoxy flooring systems adhere directly to the concrete substrate creating a hard, seamless, chemically resistant surface that is easy to clean and will last for decades. We lay self levelling, heavy duty screed, anti static, anti slip and chemical resistant systems.
PU Foam Waterproofing
Polyurethane foam waterproofing works exactly where other systems cannot work on wet, actively leaking surfaces. PU resin reacts with moisture, expands up to 30 times its volume and cures to a flexible watertight seal that stops leaks immediately. PU foam injection is used in basements, underground car parks, tunnels, lift pits and water tanks where there is no possibility of waiting for dry weather conditions.
Concrete Repair & Restoration
Most GCC buildings deteriorate faster than average as concrete suffers significant damage from coastal salinity and extreme UV & thermal cycling. If you see spalling, rust staining or widening cracks, the steel reinforcement within is already corroding. We assess, cut back to sound concrete, treat exposed rebar, reinstate with polymer modified mortar and apply protective coatings to prevent re-occurrence.
Cementitious Waterproofing
The cementitious waterproofing bonds permanently into the concrete substrate, filling the pores and capillaries and becoming part of the structure itself. It can be applied to wet surfaces, works from both sides and copes with the high hydrostatic pressures common in below-grade applications in the GCC. Our systems are certified to be in contact with potable water and as such are the right specification for drinking water tanks and treatment plants throughout the region.
Coating Services
A building without the proper coating is already being damaged. We use Reflex™ MetPrime to apply anticorrosion coatings to structural steel, pipework and tanks. We use intumescent fire-resistant coatings that meet Qatar Civil Defense and UAE fire code standards. We also offer blast mitigation systems, asbestos encapsulation and self-sanitizing coatings for healthcare and hospitality settings, reflective acrylic coatings and HarcoSil silicone roof coating.
Thermal Insulation
Air conditioning accounts for up to 70% of energy use in GCC buildings during summer. HARCOAT CIC 1000 is a ceramic based liquid insulation coating. It reflects radiated heat, thus reducing the temperature of the interior surface by up to 45% and also resists conduction and deflects convected heat. Can be applied to rooftops, industrial piping, storage tanks and process equipment Suitable for surfaces up to 180°C Water Based, Non Toxic & VOC Compliant.
Why Qatar Contractors & Developers Choose Compass
We are not a supplier, shipping products from overseas to Qatar. We are a GCC-based company with an active team and local stock in Qatar and we are ready to respond, visit the site and deliver
01Qatar-Based Team

Common Questions About Waterproofing Services in Qatar
What is the best flat roof waterproofing system in Qatar?
For new Qatar roofs, WetSuit® spray-applied liquid membrane is the best seamless, joint-free coverage rated for extreme UV and heat. For existing Qatar roofs that are in good condition, the best restoration option is HarcoSil silicone coating – silicone never hardens or degrades under the intensity of Qatar UV. Reflex™ HPW reflective acrylic coating is worth adding where reducing indoor temperatures is also a goal. We always recommend you visit the roof before, not after.
How long does waterproofing last in Qatar's weather?
A properly specified and professionally applied waterproofing system in Qatar should have a lifespan of between 10 and 20 years depending on the type of system and the level of UV exposure. The longest service life under Qatar conditions is for silicone based coatings such as HarcoSil – they do not harden, chalk or lose adhesion under the extreme summer UV. The biggest single factor in service life is surface preparation quality prior to application.
Can waterproofing be done in Qatar summer?
Yes, if you use the right products and the right technique. Most of our water-based systems have guidelines for application temperature – usually the substrate needs to be above 10°C and below the peak heat of the day. For summer Qatar projects, we schedule applications for early morning or late evening, use rapid-cure formulations where possible and always ensure that the substrate temperature is within the specified range for the product before proceeding.
Do you supply documentation for Qatar government and Ashghal projects?
Yes. We provide full technical documentation for all Qatar government and Ashghal Public Works Authority projects including method statements, technical data sheets, product approvals, thermal calculations and quality control records. Our documentation is formatted to meet Qatar project submission requirements and can be provided for review by consultants and authorities at any stage of the project.
How does HARCOAT CIC 1000 reduce energy costs in Qatar?
Qatar rooftops often reach surface temperatures above 80°C on peak summer days. HARCOAT CIC 1000 cuts this by up to 45% by reflecting radiated infra-red heat, resisting conducted heat with micro-ceramic particles and deflecting convected heat. The lower the rooftop surface temperature, the less heat will be conducted to the building by the slab, and the lower the indoor temperatures will be, which reduces air conditioning demand. In Qatar, where cooling runs for nine months of the year, the energy saving is measurable and the cost recovery is normally achieved within one or two summer cooling seasons.
