When looking for the right HDPE geomembrane sheet for a project, there are several factors to consider, such as durability, permeability, soil conditions, and cost. With the right product selection and installation methods, a high-density polyethylene (HDPE) geomembrane system has the potential to provide effective performance in a wide range of applications.

Consider Capacity Requirements.

Capacity requirements will vary depending on the project, such as the required level of protection and protection time. For instance, for critical applications requiring high-level containment services, a thicker HDPE geomembrane can provide reliable protection in extreme conditions. Conversely, thinner systems may be more suitable for lighter applications that do not require long-term durability.

Look at System Durability in Relation to Project Requirements.

Ultimately, the life span of an HDPE geomembrane system depends on its intended use. Generally speaking, thicker systems are more durable and longer lasting than thin ones and maybe a better choice for long-term projects that require extra protection. When determining the appropriate system to use for your particular project, consider factors such as the environment it will be exposed to, any potential contact with chemicals or hazardous materials, and how long the system will need to remain in place.

Consider Your Budget and Any Site-Specific Factors or Circumstances.

When deciding which HDPE geomembrane liner system to choose, consider the budget of your project. Alongside the product cost, you must also consider site-specific factors that might affect initial product selection. These may include ground slope and contour of the base, soil type and permeability, depth of underwater installation (if applicable), presence of sharp objects or debris, surface temperatures and exposure to sunlight for outdoor applications, as well as any on-site constraints such as limited access or access from one direction only.

Think About the Quality and Technical Specifications of the Geomembrane Sheet Required for your Project.

The quality and technical specifications you require for your HDPE geomembrane sheet to have to depend on your project and the specific environmental, chemical, and mechanical requirements of the job. Consider any special features such as ultraviolet stability, root resistance, or additional puncture protection that may be necessary. Additionally, it is common to select a heavier sheet liner if more layers are required for increased protection in a particular area.

Check Compatibility with Other Materials and Systems Used on the Chosen Site.

Before installing your geomembrane, it is important to check whether it is compatible with the other materials or systems that are being used at the site. Ensure that no chemical reactions occur between the two materials, such as when polymers dissolve the HDPE plastic. Test for heat stability; if you will be using non-HDPE liners, determine what temperatures they can withstand before deforming. Additionally, consider any puncture protection and weldability needs of your geomembrane relative to adjacent constructed systems.
