The Most Common Forms of Damage to Irrigation Canal Liners
Even after careful selection and installation, a canal liner made from any material can eventually become damaged and begin to leak. Concrete, geomembranes, and mortar-based systems are tougher than other materials, but they can still become damaged by specific hazards.
Issues Common to Unlined Canals
It is tempting to leave a canal unlined when it’s a small branch that is only supplying irrigation water to distant fields.
Choosing the Right Geomembrane Material for a Canal Liner
Even once you’ve narrowed down your wider canal liner choices to a geomembrane, you still have multiple materials to choose from.
Using Geomembranes as Underlayment for Concrete
If you’ve decided to pair a geomembrane from BTL Liners with some form of concrete or mortar, you’ll need to pick a product capable of pulling this duty.
Canal Lining Options
You’ll need to consider all of your options when choosing a liner for a new or existing canal. Each canal has different needs depending on the soil conditions, size, wall angle and total flow and discharge.
Options for Repairing Damaged Canals
Damaged canals don’t need to be abandoned or removed. Narrow and hard-to-see drainage and field channels need to be drained and filled to avoid serious injury to humans and animals.
How Are Canals Designed and Built?
Canals require geotechnical engineering to last for decades with minimal maintenance, but irrigation canals in particular tend to be built informally or with at least under-engineering.
Why Are Canals Essential to Modern Life?
Many people only associate canals with the waterways in Venice that are traveled by gondola, but each year thousands of miles of new canals are installed for a wide variety of uses.
