case study:
ArmorThane recently took on two major, high-priority projects in Abuja, Nigeria, for leaking roofs. However, these were not just any old roofs; these were the places of worship for thousands of Christians and Muslims, the National Mosque, and the Christian Center. Both places of worship are prideful institutions representing unity for everyone in the country. We will discuss the history of each place of worship, and then we will go into detail about the work completed at each.
NATIONAL MOSQUE
Polyurea roof coatings are the strongest waterproof protective barrier solutions for various low-slope industrial, residential and commercial roofing structures. Used to shield and waterproof, Polyurea is an ideal alternative to traditional roofing methods. A polyurea roofing system will waterproof and shield your roof or deck against damages caused by undesirable weather, expansion, and contraction with temperature shifts, abrasion, corrosion, and high and low-impact stressors.
Concrete is predisposed to cracks due to shrinkage, which could compromise the waterproofing membrane on a flat roof. Similarly, metal decks and metal screws corrode over time, which could lead to water seepage issues. This can be a critical issue when the roof leaks and a solution is required.
CHRISTIAN CENTER
The Christian Center was designed in Postmodern version of the Neo-gothic style by Nigerian architectural firm Darchiwork Group, located in Lagos. It was built by the Italian construction firm Gitto Costruzioni Generali Nigeria Ltd. The project was started around 1989, then lay dormant for several years until 2004, when the Christian Association of Nigeria created a committee to guarantee its speedy completion. The dedication, on 2 October 2005, coincided with the celebration of Nigeria’s 45th anniversary as an independent nation.
PREP WORK & APPLICATION
Before beginning, the seven crew prepared for the job by gearing up with full-face masks, a fresh air system, suits, gloves, booties, and earplugs. Then, they removed the failed membrane and prepared the concrete surface to receive ArmorThane’s flagship product, ArmorLiner polyurea spray coating.
The deck area of the roof was 4,000 sq. meters, and they chose to go with a tan color at 3mm thickness. The client added new areas, like a metal water tank coated after ArmorThane completed the deck areas.
There has not been a single leak since the work was completed last month. The entire coating application took three months to complete. Now that completed, Abuja’s National Mosque’s roof will be waterproof and safe for decades to come.
The applicator ended the project by conducting tests on the polyurea applied substrate. This involved affixing 20mm dollies to the surface. After allowing the glue to set for 24 hours, the dollies were then drilled using a 20mm coring hole bit.
- Pull 1: 619psi (95% substrate, 5% cohesive failure in coating)
- Pull 2: 714psi (100% substrate failure)
- Pull 3: 488psi (100% substrate failure)
- Pull 4: 621psi (40% substrate, 60% adhesive failure between substrate and coating)
- Pull 5: 251psi (75% substrate, 25% adhesive failure between substrate and coating)
- Pull 6: 723psi (100% substrate failure)
