Riyadh · Jeddah · Dammam · Khobar — membrane, polyurea and spray foam systems for factory, warehouse and commercial roofs, executed without shutting down your operations.
Industrial roofs in Saudi Arabia fail for reasons that have very little to do with rainfall totals. Surface temperatures on exposed metal decks routinely exceed 80°C through the summer, driving daily thermal cycling that works fasteners loose, opens seams and embrittles coatings applied only a few years earlier. Add wind-driven sand filling box gutters, chronic ponding on low-slope decks, and the dozens of penetrations created by HVAC plant, and the result is a roof that leaks in a location nowhere near where the water actually entered. As a specialist roof waterproofing company working across the Kingdom, EG CORE treats that diagnostic gap as the starting point of every project.
We do not begin by selecting a material. We begin by surveying the deck, tracing the leak to its true source, and assessing whether the existing system can be overlaid or must be stripped. Only then do we specify — membrane, polyurea, spray foam, liquid-applied polyurethane or a hybrid build-up — matched to the substrate, the exposure and the operational constraints of the facility. Materials are drawn from Sika, Mapei, Koster, MC-Bauchemie and BASF Master Builders, and every project closes with flood testing and a written handover report.
No single system suits every deck. The correct specification depends on substrate, movement, exposure and how much disruption your operation can absorb.
Reinforced APP or SBS sheet, heat-welded at laps to form a continuous barrier. The proven choice for large concrete decks where a robust, mechanically tough layer is needed beneath screed, tiles or ballast. Typically installed at 3 to 5 mm, with reinforced upstands at parapets and around every penetration.
Cures in seconds to a seamless, highly elastic film that bridges hairline movement and tolerates constant vibration. Ideal where downtime is unacceptable and where the roof carries machinery, foot traffic or complex detailing that sheet systems struggle to seal reliably.
Applied at 40 to 45 kg/m³ density, closed-cell foam delivers waterproofing and thermal insulation in a single pass while adding negligible dead load. It conforms to irregular profiles and seals corrugated sheet laps that would otherwise remain a permanent leak path. Always finished with a UV-protective topcoat.
Single-component, cold-applied and fully seamless — the practical answer for roofs dense with skylights, vents, pipe stands and equipment plinths where sheet membranes require excessive cutting and detailing. Can often be overlaid onto a sound existing system, avoiding a full strip-out.
High solar reflectance measured to ASTM C1549, cutting surface temperature and easing the thermal load on both the roof build-up and the cooling plant beneath it. Used as a protective and energy-saving finish over foam or membrane rather than as a standalone waterproofing layer.
Polymer-modified cementitious slurries that bond directly to damp concrete and remain serviceable under permanent water contact. Specified for water tanks, wet plant areas and roof zones subject to continuous standing water, and available in potable-water-approved grades.

Sequenced to keep your facility operating while the roof above it is rebuilt.
Full deck walk-over with moisture readings and, on large areas, drone imaging to map defects accurately.
Tracing the true entry point through joints, drains, HVAC bases, skylights and box gutters — not the internal stain.
Removal of failed layers, rust treatment on steel decks and pressure cleaning to sound substrate.
Routing and filling of cracks, reinforcement at upstands, corners and every penetration detail.
Screed-to-falls in ponding zones so water reaches outlets instead of sitting on the membrane.
Substrate-specific primer to establish the bond, applied only once moisture readings pass.
Installation to specified thickness, phased in zones so operations below continue uninterrupted.
48-hour flood test, wet-film and dry-film thickness verification, and a documented handover report.
Not because we are cheapest — because the roof stays dry after the warranty expires.
We identify why the roof failed before choosing what goes on it. Applying a new layer over an unresolved cause simply relocates the leak.
Systems built exclusively from Sika, Mapei, Koster, MC-Bauchemie and BASF. Field performance matches the technical data sheet.
Work is phased zone by zone and scheduled around production. Your facility keeps running while the roof is replaced above it.
Crews mobilised across Riyadh, Jeddah, Dammam, Khobar, Jubail, Yanbu and the wider Eastern Province.
Contractually documented cover of up to 10 years, with the term set by system type and exposure conditions.
We attend site, inspect the deck and issue a detailed specification and proposal within 24 hours — with no obligation.
Request a free roof survey from our technical team — we identify the leak source and specify the right system for your building within 24 hours.
