Common Questions

Frequently Asked Questions About Waterproofing in Oman

Everything you need to know about waterproofing methods, 25-year warranty, and project execution in Oman.

What makes the Modern Combo Roofing System (MCRS) superior to traditional roofing?
Traditional roofing relies on separate layers from multiple subcontractors (insulation boards, screed, bituminous membranes), creating seams and lap joints where water eventually penetrates. Al Sameem's MCRS is 'one system executed by one entity'. We spray in-situ >97% closed-cell polyurethane foam that forms a continuous joint-free monolithic thermal and moisture barrier, seamlessly continuing up the parapet walls to eliminate thermal bridging, backed by our 25-Year warranty.
How does Al Sameem provide an official 25-Year Warranty on the Combo Roofing System?
Our 25-year warranty is backed by rigid closed-cell polyurethane foam technology that does not degrade, rot, or absorb moisture, coupled with two high-grade elastomeric protective coatings and protective screed. Furthermore, as an established 100% Omani company operating since 2013 under Saeed Bin Masoud Group (CR: 1168449), we provide genuine local corporate standing and warranty support.
Can you stop active water leaks without hacking up bathroom tiles or basement slabs?
Yes! Al Sameem specializes in High-Pressure Crack Injection using specialized polyurethane and hydrophobic epoxy resins. We inject through mechanical ports directly into concrete fissures. Upon contact with water, the resin rapidly reacts and expands up to 20 times its volume, creating a flexible, permanent seal under high hydrostatic pressure without destructive demolition.
How does spray foam insulation reduce AC electricity bills in Oman's hot climate?
Roofs account for up to 60% of total heat gain in buildings in Oman. Sprayed polyurethane foam provides one of the highest thermal resistance values (R-values) available in modern construction. Because it seamlessly coats parapet skirting and up-stands, it eliminates 'thermal bridges'—meaning heat cannot bypass the insulation. Clients experience an immediate 30% to 45% drop in roof heat transmission and significant AC power bill savings.
What standard testing is conducted before handing over a completed project?
Prior to client handover, all roof and wet-area installations undergo a mandatory 24- to 48-hour continuous water ponding/flood test. Our engineers inspect the undersides, expansion joints, and rainwater outlets to certify 100% leak-free integrity before issuing our warranty certificate.
Do you service clients across all governorates of the Sultanate of Oman?
Yes. While our headquarters is located in Al Ghubra / Al Athaiba, Muscat, our mobile technical crews and engineering equipment service projects across Muscat, Al Batinah (Sohar, Barka), Al Dakhiliyah (Nizwa), Al Sharqiyah, and Dhofar (Salalah).
