Products Description
A garden liner, also known as a plastic geomembrane liner, is a material used to create a waterproof barrier in various applications, including pond construction. It is typically made of high-density polyethylene (HDPE) or other synthetic materials that are durable and resistant to degradation.
When used in a pond, a garden liner serves as a barrier between the water and the surrounding soil, preventing leakage and maintaining water levels. It is commonly used in the construction of garden ponds, fish ponds, or water features.

To install a garden liner in a pond, you would typically follow these steps:
Excavation: Dig the pond area to the desired shape and depth, ensuring it is free from sharp rocks, roots, or other debris that could puncture the liner.
Preparation: Smooth out the soil and remove any remaining debris or sharp objects. It's important to have a clean and level surface for the liner installation.
Underlayment: Place an underlayment material such as geotextile fabric or sand over the excavated area. This provides an additional layer of protection for the liner against punctures and helps to cushion the liner.
Unrolling the liner: Carefully unroll the garden liner over the pond area, ensuring it covers the entire excavation with some excess material overlapping the edges.
Securing the liner: Anchor the liner in place using rocks, bricks, or other weights around the edges. This helps to prevent shifting or movement of the liner during filling and over time.
Folding and sealing: If necessary, fold and seal the excess liner material at the edges of the pond. This creates a neat finish and helps to prevent water from seeping under the liner.
Filling the pond: Slowly fill the pond with water, being cautious not to damage the liner. As the pond fills, the weight of the water will help to press the liner firmly against the soil.
Trimming excess liner: Once the pond is filled, trim any excess liner material, leaving a few inches of overlap to account for fluctuations in water levels.

Plastic film type: Plastic film liners are usually made of High Density Polyethylene (HDPE), which has durability, corrosion resistance, and penetration resistance. Other types of plastic film materials can also be used for different applications, such as polyvinyl chloride (PVC) plastic film.
Size and thickness: The size and thickness of the plastic film liner can be selected according to specific application requirements. The common thickness range of plastic film is 0.5 millimeters to 2 millimeters, depending on the required impermeability and durability.
Anti permeability: The main function of the plastic film liner is to provide an impermeable barrier to prevent water from leaking into or out of the soil. This is particularly important for horticultural ponds, fish ponds, or other water projects.
Installation method: The installation process of the plastic film liner usually involves excavating the pond area, laying the liner material, unfolding and fixing the plastic film, filling the water body, and other steps. During the installation process, special attention should be paid to avoiding damage to the plastic film caused by sharp objects or edges.
Maintenance and upkeep: Regular inspection and maintenance are necessary to ensure the lifespan and reliability of the plastic film. Avoid placing heavy or sharp objects on the plastic film, and avoid using chemicals that are corrosive to the film. In addition, regularly clean up debris and plants in the pond to reduce pressure and friction on the plastic film.
