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!

How Do Liners Help Minimize Contamination Risks During Heavy Winter Rainfall?
Liners help minimize contamination risks during heavy winter rainfall by creating a stable barrier that keeps stored manure or wastewater from seeping into the ground or overflowing into nearby drainage paths.
Read More
Why Is Liner Integrity Especially Important Before Spring Thaw?
Liner integrity is especially important before spring thaw because this is when stored liquid can rise quickly and put extra pressure on a lagoon or pit.
Read More
What Role Do Liners Play In Preventing Accidental Winter Spills?
Liners play a key role in preventing accidental winter spills by keeping manure or wastewater securely contained when freezing temperatures make storage systems more vulnerable.
Read More
How Do Liners Support Nutrient Management Planning?
Liners support nutrient management planning by giving operators a clearer understanding of how much manure or wastewater is actually being stored over the winter.
Read More
How Do Liners Help Protect Nearby Wetlands During Winter Runoff Events?
Liners help protect nearby wetlands during winter runoff events by keeping stored manure or wastewater from escaping when soils are frozen and unable to absorb moisture.
Read More
Can Liners Help Reduce Emergency Spreading During Winter Storms?
A liner alone won't help reduce the need for emergency spreading during winter storms, but adding a cover certainly will.
Read More
What Temporary Containment Options Are Available During Winter?
Temporary containment options during winter often focus on creating a stable, leak-resistant holding area until conditions improve for permanent work or land application.
Read More
Can Liners Prevent Nutrients From Leaching Into Frozen Soil?
Liners can greatly reduce the chance of nutrients leaching into frozen soil because they form a continuous barrier that stops liquid from moving downward, even when the ground is cracked or uneven from freezing.
Read More
How Does A Lined Lagoon Help Control Winter Ammonia Loss?
A lined lagoon helps limit winter ammonia loss by preventing seepage into the surrounding soil, which keeps more of the nitrogen-rich liquid confined where it can be managed.
Read More
Do Liners Help Meet Regulatory Nutrient-Management Requirements?
Liners can make it much easier to stay within regulatory nutrient-management limits because they create a defined barrier that keeps stored manure or wastewater from seeping into soil or groundwater.
Read More
Does Winter UV Exposure Affect Synthetic Liners?
Winter UV exposure can still affect synthetic liners, though its impact is usually weaker than in summer because the sun sits lower in the sky and daylight hours are shorter.
Read More
How Can I Reduce Nutrient Runoff During Winter Snowmelt?
You can limit nutrient runoff during snowmelt by keeping exposed soil to a minimum and making sure manure or stored materials are well contained before freeze-up.
Read More
Do Welded Seams Hold Up Well In Freezing Climates?
Welded seams generally perform well in freezing climates when the liner material is designed for cold-weather use and the seams are made with proper equipment and technique.

How Long Do RPE Liners Last In Harsh Winter Environments?
RPE liners are known for their long service life, even in regions that experience severe winters.
Read More
Can Liners Reduce The Risk Of Nutrient Loss In Thaw-Freeze Cycles?
Yes, liners can be effective in limiting nutrient loss during cycles of thawing and refreezing.
Read More
Can Liners Be Installed During Winter Months?
Liners can be installed during winter, but the process requires extra care to ensure good performance.
Read More
Will Freezing Temperatures Reduce Liner Flexibility?
Freezing temperatures can reduce the flexibility of some liner materials, but the extent depends on the type of plastic used.
Read More
Are RPE Liners Resistant To Frost Damage?
RPE liners are generally well suited for regions that experience frost because their reinforced structure helps them tolerate ground movement during freeze-thaw cycles.
Read More
How Does RPE Compare To HDPE In Winter Durability?
RPE generally performs better than HDPE in winter because it stays flexible in low temperatures and can handle movement in the surrounding soil without cracking.
Read More
Do Synthetic Liners Become Brittle In Cold Weather?
Most modern synthetic liners are engineered to stay flexible even in very cold conditions, so brittleness is far less of a concern than it once was.
Read More
How Do I Prevent Winter Seepage From My Storage Pit?
Preventing winter seepage starts with keeping the pit’s barrier layers strong and well-protected before temperatures drop.
Read More
What Kind Of Winter Maintenance Is Needed For Waste Lagoons?
Your primary winter maintenance goals are protecting equipment from ice damage and managing water levels to prevent overflow.
Read More
Is It Normal For Earthen Lagoons To Absorb More Liquid During Freeze-Thaw Cycles?
No, an earthen lagoon should never "absorb" liquid; if you notice pond levels dropping through freeze-thaw cycles, you probably have a leak.
