Nasra GeoSyn · Riyadh · Saudi Arabia

Engineering the unseen
foundations of a sustainable Kingdom.

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.

— What we do

What you see above. What we engineer beneath.

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.

Our Solutions

Six engineering divisions.

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.

On-Site Engineering

We don't disappear when the materials arrive.

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.

Sustainability at the Core

Aligned with the United Nations Global Compact. Engineered for the long horizon.

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.

10
UN Global Compact Principles

Human rights, labour, environment, and anti-corruption — embedded into how we operate, source, and deliver across every project.

50+ yr
Design Life

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.

Lower Embodied Carbon

Geosynthetic systems carry significantly lower embodied carbon than conventional mineral-based alternatives, and their long service life reduces lifecycle impact further.
