FNAM Contracting is a Leader in Specialized HDPE Installation

Fnam Contracting is the top installer of HDPE Geomembrane Lining, Waterproofing Membranes, Geotextile, Concrete Protective Liner (CPL), Geosynthetics Clay Liner (GCL), Geogrids, Geocells & Geonets in Saudi Arabia & other Gulf Countries. We also provide cost-effective, innovative solutions to repair or upgrade your existing under-performing or damaged HDPE system.

FNAM Cont. also provides an experienced staff of full time HDPE installers, each with many years of safe work history. Our team members are fully capable in all aspects of HDPE installation and repair. We believe in a team approach that empowers all persons with responsibilities and rewards; which in turn transfers to a better installation value of our customers.

We have completed projects in nearly every industry with containment needs. Complex specifications, challenging terrain and tight deadlines are no match for our dedicated teams of projects managers, engineers and installation crews.


As a leader in the industry FNAM Cont. has successfully completed numerous HDPE Industrial/ Municipal liner projects. We also provide innovative solutions to repair or upgrade existing under-performing or damaged HDPE system.
We are proud to offer you a glimpse at some of our more recent work. Please click the projects name for a short description of the work we performed and view the images taken at various stages throughout the installation or repair process.

General Information:

The use of Geomembrane in civil and environmental applications is becoming more widespread as there develops a greater understanding of the effects of contaminated ground conditions on structures and the environment. FNAM Cont. is able to offer a wide range of membranes that are compatible the diverse range of applications and contaminates likely to be encountered.

Production Information:

Geomembrane are supplied by FNAM Cont. as High Density Polyethylene (HDPE), Linear Low density Polyethylene (LLDPE), and Low density polyethylene (LDPE) are able to arrange either on-site or factory fabrication of these products to suit the application.

The Low Density Polyethylene product is supplied in a folded configuration for ease of fabrication. FNAM Cont. is able to advice on the most appropriate product for each specific application. FNAM Cont. is able to offer a black/white Geomembrane range that is particularly suitable when welding in hot climates. The black/white characteristic minimizes the formation of wrinkles which has a detrimental effect on leakage rates, should the membrane be punctured.

Geomembrane introduction

Geomembrane is manufactured from High Density Polyethylene resins. The surface of both sides is smooth. The products are manufactured by the technology of co extrusion –blown triple layer. It provides Geomembrane with specific properties on each layer, e.g. bicolor and/or textures designs.


Excellent physical and mechanical performance, high tearing resistance, good deformation adaptability , high puncture resistance, high aging resistance, high UV resistance, anti-acid & alkali, excellent low & high temperature resistance , innocuous, long life span, perfect water proof performance, seepage and humidity resistance.

Specifications and Testing

Fnam Cont. Also provide the facility of equipment for testing on site to assure the best quality of geomembrane lining.
The seams should be tested to ensure good properties of the liner of the seams. Some of the required tests are destructive while the others are non-destructive.

Destructive Testing

All field seams should be non-destructive tested over their full length using Air Pressure Needle with gauge pressure up to 30 PSI.
The peel test is the greatest proof that a seam will have the strength to last of a flexible membrane liner.

  • Air pressure test
  • Tensio Test

Non-Destructive Spark Testing

100% of all surface extrusion welds will be tested with the High Voltage Spark Test unit required for testing will be supplies by installer.
