Stormwater Management & SuDS
Geo-cellular soakaway, attenuation, passive irrigation, and root-space systems. The Kingdom's largest SuDS project was delivered by NGS.
View division →Nasra GeoSyn (NGS) is Saudi Arabia's sustainable civil and environmental engineering arm — supplying the geosynthetics, stormwater (SuDS), waterproofing, and ground-stabilization systems that hold the Kingdom's infrastructure in place. Our work is rarely seen, because it sits beneath what people use every day. That is exactly the point.

Above the line: the buildings, parks, and roads people see. Below it: the geotextiles, drainage cells, and geocellular tanks that move water, hold ground, and keep all of it standing. The diagram shows both — NGS engineers everything beneath the line.
NGS designs, supplies, and supports installation across six engineering disciplines — each built for the demands of Saudi Arabia's climate, ground conditions, and Vision 2030 infrastructure.

Geotextile, geogrid, GCL, geofoam, geocomposite, drainage cell, geocell, erosion control, silt curtain, geobag, geotube, and panel drain systems.
View division →
Pre-applied, post-applied, FPO and HDPE, EPDM, TPO, and PVC membrane systems for below-grade, podium, tunnel, and reservoir applications.
View division →

Elastomeric bearings, expansion joints, butyl seal systems, post-tensioning, tunnel waterproofing, and NFPA and Dutch RWS-rated fire protection.
View division →
Mechanically Stabilized Earth wall systems, Gabion box systems, and plantable soil retention. From highway retention to architectural walls.
View division →
Hydraulic design, geotechnical engineering, BIM modeling, technical advisory, value engineering, and installation supervision and training.
View division →Geosynthetics succeed or fail at the point of installation. That's why NGS engineers stay on the ground with the contractor — handling installation supervision, on-site training, and quality control throughout the works.
It's how we delivered the largest SuDS project in the Kingdom — and it's how we approach every project that follows.
As a participant of the UN Global Compact, NGS commits to the ten principles covering human rights, labour, environment, and anti-corruption — and translates them into the engineering of every product we supply.
Human rights, labour, environment, and anti-corruption — embedded into how we operate, source, and deliver across every project.
Each NGS system is engineered for a minimum 50-year service life under typical Saudi buried conditions — the longer it lasts, the lower its lifecycle impact.
Geosynthetic systems carry significantly lower embodied carbon than conventional mineral-based alternatives, and their long service life reduces lifecycle impact further.
NGS holds the certifications and supplier approvals required to deliver on Saudi Arabia's most demanding projects.
Certified under United Accreditation Foundation. Audited annually with full management system documentation maintained.
Environmental management system certified — covering material sourcing, site operations, waste, and lifecycle responsibility.
Active participant of the United Nations Global Compact — committed to the ten principles on human rights, labour, environment, and anti-corruption.
Occupational health and safety management system. Field operations, installation supervision, and office safety all covered.
Supplier approvals held with Bechtel, Parsons, Jacobs, AECOM, AtkinsRéalis, WSP, and the major PMCs delivering Saudi Vision 2030.
Every system is specified for the Kingdom's specific ground, temperature, salinity, and rainfall characteristics — not imported one-size-fits-all solutions.
ISO 9001:2015 Quality, ISO 14001:2015 Environment, ISO 45001:2018 Health & Safety — accredited under United Accreditation Foundation.
Approved supplier across Bechtel, Parsons, Jacobs, AECOM, AtkinsRéalis, Worley JESA, WSP, and Faithful+Gould project teams.
Installation supervision, hands-on training, and QA/QC support throughout the works — we don't disappear when the materials arrive.
Riyadh-based operations with dedicated technical, sales, and project teams responding on Saudi project timescales.
UN Global Compact participant. Every solution selected for 50-year design life, recyclable materials, and measurable carbon reduction.

Nasra GeoSyn (NGS) is the engineering arm of the Nasra Group, a Saudi company supplying Sustainable Urban Drainage Systems (SuDS), geosynthetics, waterproofing, MSE walls, bridge and tunnel systems, and BIM engineering for Vision 2030 infrastructure.
NGS is based in Riyadh, Saudi Arabia, and serves projects across the Kingdom including NEOM, ROSHN, Diriyah, Qiddiya, King Salman Park, AlUla, and Red Sea Global.
Yes. NGS holds ISO 9001 (Quality), ISO 14001 (Environment), and ISO 45001 (Occupational Health & Safety) management-system certifications under UAF accreditation, and is a participant in the UN Global Compact.
NGS engineers outcomes, not just products — providing product-performance calculations, value engineering, on-site installation supervision, and long-term operation and maintenance guidance, with a minimum 50-year design life under Saudi ground conditions.
