In the last 1980's in line with its policy of continuous research and development SNS BUILDING SYSTEMS along with its UK. Associates developed an alternative building material, with a gypsum base for certain specialist applications. The earliest form of this material, known as Jesmonite, was used to make the intricate and complex exterior decorative mugarnassat, wall finishes and column claddings of the King Saud Mosque in Jeddah. Not only Jesmonite have the advantage of offering many high quality finishes, e.g. imitation marble, stone, slate, metallic, etc. but it is also much lighter than comparable materials and hence easier to fix.

In 1990's the company was awarded a major Jesmonite contract, for intricate ground floor arches for one of the buildings on the Canary Wharf project in London's Docklands, UK. (the largest building complex in Europe). The architects for the projects, were Skidmore Owens & Merril of the USA. They regularly visited the Riyadh factory, to inspect the quality control during production, thereby gaining their full confidence in SNS BUILDING SYSTEMS
