Buyer's guide
Buying HDPE geomembrane in the UAE: what to check before you order
Two quotations for the same basin can differ by half, and both can be for something described as “1.5 mm HDPE geomembrane”. Here is what…
Technical notes
Geomembrane liner guides and field notes
Specification, welding, thickness, cost and the practical detail of lining basins in a country where it is 45 degrees for a third of the year. Written for the people who actually buy and install this material.
Materials
HDPE vs LLDPE vs PVC: choosing the right geomembrane
Three polymers, three very different personalities. Picking between them is not about which is best — it is about what the ground under your basin is…
Installation
Hot wedge vs extrusion welding: which seam goes where
Sheet arrives from the mill consistent and certified. Seams are made on site, in the heat, by people. That is where lining projects succeed or fail.
How-to
How to line a pond with HDPE geomembrane
The sheet is the easy part. Everything that decides whether a pond holds water happens before the first roll comes off the truck and after the last seam…
Water management
Canal lining: how much water an unlined channel loses
Seepage from an open channel is invisible. There is no leak to point at — just water that arrives at the far end in smaller quantity than it left.
Environmental
Landfill liner systems explained, layer by layer
A landfill liner is not a sheet. It is a sequence of layers, each doing one job, and the interfaces between them decide whether the slope stands up.
Agriculture
Lining irrigation reservoirs: what it saves a UAE farm
A farm reservoir on sand loses water two ways at once. Telling the two apart is the first step, because only one of them is fixed by lining.
Materials
Why a cushion geotextile is the cheapest insurance on a liner
It is a fabric that costs a fraction of the membrane above it, and leaving it out is the most expensive saving on most lining projects.
Specification
Geomembrane thickness: mm, mil and microns without the confusion
American specifications say mil. Gulf specifications say millimetres. Chinese mills sometimes say microns. They are the same measurement and mixing them…
Cost
What drives the price of a geomembrane liner
Nobody can publish a meaningful rate for geomembrane, because the biggest input is a commodity. What you can do is understand the structure of the number.
Durability
How long does a geomembrane liner last in UAE sun?
Buried liner is a decades-long asset almost anywhere. Exposed liner in a Gulf summer is a much more interesting question, and the answer depends on things…
Quality control
Finding leaks: seam testing and leak location surveys
Most liner leaks are not seam failures. They are punctures made after the seams passed — which is why the testing regime has more than one method in it.
Field notes
Geomembrane work across the UAE, emirate by emirate
The country is small enough that one stockholding serves all of it, and varied enough that the lining job in Ras Al Khaimah is nothing like the one in Al…
