LESSONS LEARNED

Originally specified a 45RPP geomembrane for a project due to its UV resistance, puncture and tear strength, cold cracking resistance, and compatibility with fish rearing. However, due to supply chain issues, it was not available, so engineers substituted a 45 mil thick LLDPE geomembrane that shares similar properties and was available within the project timeframe.

HOW THE USE OF FABRICATION IMPROVED THIS PROJECT

The utilization of factory fabricated geomembranes and ballast tubes proved to be a crucial factor in the successful completion of the project, despite facing various obstacles. Originally scheduled for installation in August 2021, the project faced supply chain issues with the specified geomembrane, causing a delay until late October. Despite the limited welding hours due to the colder temperatures in Riverdale, North Dakota, the project was able to minimize field geomembrane seaming by utilizing large fabricated panels, enabling the crew to perform quality welding operations when optimal temperatures were reached. Additionally, the use of fabricated panels and ballast tubes played a vital role in mitigating the challenges posed by the strong North Dakota winds during late October, ensuring the safety of all crew members and allowing for efficient ballasting. Through the implementation of these measures, the project was completed with the highest quality standards, demonstrating the effectiveness of innovative solutions in overcoming complex obstacles.

60 Mil Hdpe Geomembrane Fabricated Liners

Most HDPE liners are highly resistant to chemical damage regardless of their thickness, with 40 and 60 mil liners demonstrating equal levels of protection against UV and corrosion. However, there are some important differences to consider as the thickness of the liner increases.

In terms of physical durability, a thicker liner offers increased strength and puncture resistance, making it better suited for outdoor applications where exposure to weather and environmental damage is a concern. The thicker material can withstand more wear and tear, and is less likely to be damaged by heavy equipment or other impacts.

On the other hand, a thicker liner comes with some drawbacks as well. It is heavier and more expensive to transport and install, and may require more seams during installation due to its shorter roll length. Additionally, a thicker liner will be less permeable than a thinner one, which can be an advantage in some cases but may also limit its suitability for certain applications.

In general, a 40 mil HDPE liner will be sufficient for most uses, but regulatory requirements may dictate the use of a 60 mil liner in some cases. When choosing between different thicknesses, it is important to consider factors such as the specific application, the potential for physical damage or exposure to harsh conditions, and the cost and logistical considerations of transportation and installation.

In certain construction projects, regulatory bodies such as the Environmental Protection Agency (EPA) will enforce rules that dictate the minimum thickness of the HDPE liner used. For instance, in landfills designed to contain non-hazardous waste, the EPA mandates a minimum average thickness of 60 mil to ensure the liner can withstand the weight of the waste and the stresses of construction.

To ensure optimal performance, engineers may opt for HDPE liners that are 60 mils or thicker for applications that demand greater liner strength or lower permeability. The decision to increase liner thickness may arise from the calculation that a thinner liner is unable to withstand a region’s 100-year weather event or is ill-equipped to handle seismic activity.

These requirements, combined with proper construction and quality control, serve to minimize the risk of tearing or puncturing of the liner. A thicker HDPE liner can endure more physical damage, making it a superior option for regions prone to seismic activity.

In conclusion, regulatory bodies like the EPA establish minimum thickness requirements for HDPE liners used in construction projects. Engineers may choose to increase liner thickness to ensure optimal performance in demanding applications. Regardless of thickness, proper construction and quality control play a critical role in ensuring the longevity and effectiveness of the liner.
