Pond liner and underlay are vital for anti-seepage in pond construction, each performing distinct yet complementary functions to maintain the pond’s longevity. The underlay is positioned under the geomembrane liner, shielding it from punctures and abrasions caused by rocks, roots, or sharp soil objects.
BPM Geomembrane, as a leading manufacturer, wholesales liners and offers installation services for oxidation pond projects in Malaysia.
1. What is Pond Liner and Underlay?
Geomembrane pond liner and underlay are cost-effective, solvent-resistant anti-seepage materials. The geomembrane liner is impermeable, flexible, and adaptable to earth surfaces, trusted for containment of fluids from water to oils and chemicals. BPM’s HDPE geomembrane and underlay have anti-seepage properties, chemical resistance, stress cracking ability, low permeability, UV resistance, and low-temperature toughness. They also exhibit strong anti-seepage and isolation performance. All BPM products meet GRI GM13 and ASTM standards.
Features
- Cushioning: It provides a protective cushion between the pond liner and any sharp objects such as stones or roots.
- Puncture Prevention: The underlay reduces the risk of the pond liner being punctured, thus extending its lifespan.
- Stabilization: It helps stabilize the base of the pond, preventing the liner from moving or sinking into the soil.
- Moisture Management: Some underlay materials are designed to move moisture away from the liner, helping to maintain a stable water table.
- Separation Layer: Underlay acts as a barrier between the liner and subsoil, preventing fine particles from migrating upwards and potentially clogging the system.
- Installation Ease: Underlay materials are typically easy to lay down and cut to the required pond shape, simplifying installation.
- Permeability Options: Different underlay types offer varying levels of permeability, allowing designers to choose the right balance between protection and drainage.
2. Why Chose BPM Pond Liner and Underlay for Oxidation Pond Project in Malaysia
In 2020, we were contacted by customers from Malaysia who had found us through Google. They wanted to buy geomembrane liners for building oxidation ponds. The driving force behind their choice was the issue of animal waste flowing untreated across lands, which led to several risks like pest infestations, diseases, and contaminations. Pests and untreated manure can transmit diseases, causing crop infections that may eventually harm consumers’ health. Moreover, when organic matter in the soil ferments prematurely, it provides an ideal condition for bacteria and pests to thrive, leading to plant diseases and bugs.
Solution
To solve these issues, using a geomembrane liner and underlay is crucial. They seal the oxidation pond, forming a large sewage anaerobic reactor. The liner resists high and low temperatures, surviving asphalt, oil, tar, acid, alkali, salt, and corrosive chemicals. It’s anti-aging, UV-resistant, decomposition-resistant, and needs no extra coverage. Using this system in ponds saves resources and protects the environment.
This innovative solution helps Malaysian customers reduce waste risks, promote environmental protection, and ensure crop and consumer health.
