Client Testimonials

Trusted by Engineers Worldwide

Synhens' HDPE geomembranes have performed flawlessly across three of our reservoir lining projects in Southeast Asia. The material consistency between batches is exceptional, and their technical team provided detailed installation guidance that made a real difference on site.

★★★★★
James Whitfield Senior Civil Engineer · Australia

We sourced biaxial geogrids for a highway embankment rehabilitation project and were impressed by both the product quality and the speed of delivery. Synhens communicated proactively at every stage and even helped us optimise the specification to reduce material costs.

★★★★★
Carlos Mendoza Project Director · Mexico

The nonwoven geotextiles we received met every parameter in our design specification. Quality control documentation was thorough and the third-party test reports gave our client full confidence. We will continue working with Synhens on future contracts.

★★★★★
Ahmed Al-Rashidi Procurement Manager · UAE

We used Synhens geocells for a coastal erosion control project with complex slope geometry. The product was easy to deploy and the infilled sections have held up perfectly through two wet seasons. Excellent value for a demanding application.

★★★★★
Sophie Leclerc Environmental Engineer · France

Synhens supplied drainage boards for a large-scale green roof installation across multiple commercial buildings. Lead times were met without exception and the product dimensions were accurate throughout. A reliable partner we would confidently recommend to colleagues.

Our most frequently asked questions

How to choose the commonly used specifications for 3D vegetation nets?

Classified by the number of layers: 2 layers, 3 layers, 5 layers; EM3 and EM4 are commonly used in engineering projects. For steeper slopes and heavier rainfall, it is recommended to use higher models.

What are the applicable scenarios for 3D vegetation nets?

Highway and railway slopes, mountain revegetation, riverbank protection, landscaping, etc.

What are the advantages of eco-bags?

They are permeable to water and air, resistant to aging, can be used for vegetation cover, do not pollute the environment, and are easy to install.

How long do eco-bags last?

In normal outdoor environments, they last 5-10 years or more, depending on the material and the environment.

What are geotextiles used for?

They mainly serve functions such as filtration, drainage, isolation, reinforcement, seepage prevention, and protection.

Where are geomembranes used?

Landfills, biogas digesters, fish ponds, reservoirs, chemical treatment plants, and tailings ponds.
