Knowledgebase
Welcome to the BTL Knowledgebase. Ever since we started lining ponds, creating covers, and helping people with their projects, we've gotten asked a lot of questions. Many of these questions are repeatedly asked, so we put together the BTL knowledgebase to help answer any questions you had about a particular subject. We are adding new questions every month, so continue to check back often!

Why are geomembranes used in barren ponds?
Geomembrane liners are often used in barren ponds for environmental protection and operational efficiency.
Read More
Are the liners for fish ponds the same ones used in mining?
Geomembranes are particularly popular as pond liners, even when the pond in question is holding mining waste rather than fresh water and fish.

What is a bottom liner in a mining operation?
The foundation of any modern mining treatment plant is the bottom liner.
Read More
Are geomembranes waterproof?
Geomembranes are waterproof sheets that are used as hydraulic barriers.
Read More
Where are geomembranes used?
Geomembranes are being used in environmental, hydraulic, transportation, and oil and gas applications as well as in mining and the waste industry.
Read More
What industry uses the most geomembranes?
Up to 40% of the world's geomembranes are used by the mining industry each year.
Read More
Are geosynthetics (geomembranes) important in the mining industry?
Geosynthetic materials have become critical components in the design and performance of mining facilities.
Read More
What are the uses of geomembranes in mining?
The most extensive use of the geomembrane liners has been, and remains, in the construction of evaporation ponds and heap leach pads
Read More
What are the different types of mining geomembranes available?
Several types of geomembranes are available for use in mining applications, each offering unique properties and characteristics to suit specific project requirements.
Where can I purchase EPDM pond liners?
