Expert Waterproofing Services in Saudi Arabia — Riyadh, Jeddah & the Kingdom
Compass Waterproofing delivers professional waterproofing, coating, and thermal insulation services across Saudi Arabia. Our on-ground team serves Riyadh, Jeddah, Dammam, and all major Kingdom development zones — with certified products, proprietary spray equipment, and full compliance documentation for every Saudi project.
Why Waterproofing Is Different in Saudi Arabia
The Kingdom Has the Most Demanding Waterproofing Environment in the GCC
Saudi Arabia is the largest construction market in the Middle East, and the climate is unforgiving across most of it. From the megaprojects of NEOM and the Red Sea Development to the housing programmes around Riyadh and the industrial expansion in Jubail and Yanbu, every structure here sits inside a combination of stresses you do not find together anywhere else.
Interior cities bake at over 50°C in summer with very low humidity. The Eastern Province coastline combines that heat with constant salt-laden air off the Arabian Gulf. The Red Sea coast adds its own conditions. In our experience, a waterproofing system that performs in Riyadh will not necessarily perform in Dammam, and a system that holds up on a Jeddah seafront tower will face very different stresses than one on a mountain resort in NEOM. The specification has to follow the actual site, not the country.
Our technical team has been working across the Kingdom long enough to know which systems survive these conditions. We do not specify from a catalogue. We specify from what we have seen fail and what we have seen last
Peak Heat Above 52°C
Riyadh and Al-Ahsa regularly exceed 50°C in summer. Membranes, slabs, and sealants not rated for sustained substrate heat expand, contract, and fail within a season or two.
Extreme UV in a Cloudless Climate
One of the highest annual UV indexes recorded anywhere. Standard acrylic and bituminous membranes chalk and crack — only UV-rated silicone and certified liquid membranes last a full service life.
Red Sea & Gulf Salt Exposure
Jeddah, Yanbu, and the Eastern Province coastline sit in chloride-laden air that penetrates concrete and attacks rebar — visible spalling shows years after the damage begins inside.
Sandstorms & Abrasion
Wind-driven sand abrades membranes, coatings, and exposed sealants. Unprotected acrylic topcoats can lose measurable film thickness in a single Riyadh sandstorm season.
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 Saudi Contractors & Developers Choose Compass
We are not a supplier shipping products from overseas to Saudi Arabia. We are a GCC-based company with an active team and local stock in the Kingdom — ready to respond, visit the site, and deliver.
01Local Stock & On-Ground Saudi Team
We hold product stock and a technical team inside the Kingdom. That means same-day response, site visits in Riyadh, Jeddah, and the Eastern Province within 24 to 48 hours, and no waiting on shipments stuck at customs. In our experience, this is the biggest single difference between us and the overseas brands working through Saudi agents.
02Saudi Building Code & SASO Compliant
Our products and documentation comply with Saudi Building Code (SBC 201, 304, 305 as applicable), SASO standards, and Saudi Civil Defense fire code where structural fire protection is required. Method statements, technical data sheets, and product approval submissions are formatted in the layout Saudi authorities expect — not a generic template translated from English.
03Bilingual Arabic & English Documentation
Every method statement, technical data sheet, and warranty paper is provided in both Arabic and English as standard. For Saudi government tenders, Aramco submissions, and Vision 2030 megaproject consultants, bilingual documentation is not optional — and most international suppliers cannot provide it at the submission stage.
04WetSuit® Spray System (Proprietary)
On Saudi projects we deploy our own heated plural-component spray equipment, which delivers uniform film thickness and continuous coverage you cannot achieve manually on the kind of large rooftops and podium decks typical of Saudi development. We verify wet film thickness during application and dry film thickness once cured.
05ASTM, BS & ISO Certified Products
Every product we use on Saudi work has published technical data sheets and international certification — ASTM C836 for liquid-applied membranes, ASTM C957 where applicable, BS 8102 for below-grade waterproofing design, ISO 9001 quality management on supply. No unbranded generic materials, full traceability.
06Vision 2030 & Megaproject Ready
We supply Vision 2030 developments with the documentation depth, compliance rigour, and material consistency these flagship projects demand. Saudi megaproject consultants want to see the same product spec, the same applicator standard, and the same documentation format across multi-year construction phases — that continuity is what our on-ground Saudi team delivers.
Our Saudi Project Process — Honest, Documented, Professional
The process starts with a thorough consultation to understand precisely what waterproofing needs you have. Whether you own a residential property, commercial building or large industrial complex, our technical experts offer clear, personalized advice — and back it up with the right products and professional installation.
Same-Day Response
Contact us by call, WhatsApp, or email about your Saudi project. We respond the same day with a technical person who asks the right questions before recommending anything. We do not have call centres or sales scripts.
Saudi Site Visit
We visit your Riyadh, Jeddah, Dammam, or megaproject site to inspect the substrate and existing conditions. We never quote without seeing the job first. We have been burned often enough by drawings that did not match site reality — every Saudi building is different.
System Recommendation
We recommend the system that fits the Saudi climate, the substrate, and the budget — not the most expensive option, the right one for the specific conditions of your Kingdom building. If a cheaper system will do the job, we say so
Clear Bilingual Proposal
Full scope, product specifications, method statement, and transparent pricing — formatted in Arabic and English and ready for Saudi consultant review and authority submission. No vague scope, no hidden line items
Professional Installation
Trained applicators, calibrated spray equipment, and quality checks throughout. We work to specification on every Saudi project and do not leave until the job is right. If we find a problem mid-job we tell you, we do not paper over it.
Documented Handover
Inspection records, flood test certificates, product data sheets, and warranty papers — in both Arabic and English. Everything a Saudi contractor or building owner needs at project completion and for the next consultant who reviews the file in five years
Common Questions About Waterproofing Services in Saudi Arabia
Which is the best roof waterproofing system for Riyadh and Jeddah?
It depends on whether the roof is new or existing. For new Saudi roofs, WetSuit® spray-applied liquid membrane gives you seamless, joint-free coverage rated for the extreme UV and heat of the Kingdom. For existing roofs in good structural condition, HarcoSil silicone coating is usually the best restoration call — silicone does not harden or degrade under Saudi UV the way acrylic topcoats do. Where energy reduction also matters, Reflex™ HPW reflective acrylic gives you waterproofing and solar reflectance in one coat. We always inspect the roof before recommending. A Jeddah seafront roof and a Riyadh inland roof need different specifications — anyone who tells you otherwise is selling, not specifying.
Do your products meet Saudi Building Code (SBC) and SASO requirements?
Yes. Our products and documentation comply with Saudi Building Code requirements (SBC 201 general, SBC 304/305 thermal, SBC 801 fire as applicable), SASO standards, and Saudi Civil Defense fire code where structural steel fire protection is in scope. We prepare method statements, technical data sheets, and product approval submissions in the format Saudi authorities expect, and we provide everything in both Arabic and English as standard — not as an afterthought translation.
Do you supply NEOM, Red Sea Project, and other Vision 2030 megaprojects?
Yes. We work on Vision 2030 megaprojects. These projects demand documentation depth, certified international standards, and material consistency across multi-year construction phases — which is exactly what our proprietary WetSuit® system, certified product range, and on-ground Saudi team are built around. Specific references on request — we cannot list named projects on a public page without client approval.
How long does waterproofing actually last in Saudi conditions?
Honest answer: 10 to 20 years for a well-specified, professionally installed system. Silicone coatings (HarcoSil) tend to last longest in Kingdom conditions — silicone does not harden, chalk, or break down under Saudi UV. WetSuit® polyurea systems typically deliver 15 to 20 years on roof applications. Cementitious systems below grade can last the design life of the structure. The single biggest factor in service life is surface preparation before application. We have seen excellent products fail in five years because the substrate was not prepared correctly, and we have seen average products last fifteen years because the prep was done right.
Do you handle Aramco and SABIC industrial projects?
Yes. We supply coating, lining, and thermal insulation systems compatible with Aramco engineering standards (SAES-H series for protective coatings) and SABIC procurement specifications. For Aramco and SABIC work we provide Aramco-format documentation, certified products, and applicators experienced with oil and gas site requirements including hot work permits, confined space, and inspection hold points.
Can waterproofing be applied during Saudi summer?
Yes, with the right products and scheduling. Most of our water-based systems have application temperature limits — typically substrate above 10°C and below a specified maximum (often 40 to 45°C depending on product). For Saudi summer work in Riyadh and the Eastern Province we schedule applications for early morning or late evening, use rapid-cure formulations where appropriate, and verify substrate temperature with an infrared thermometer before starting. Mid-afternoon application in July on a sun-exposed substrate is asking for trouble — we will not do it even if the client pushes.
