How to Do Oil Tank Bottom Anti-Seepage? One Set of Geomembrane + Filament Geotextile Is Enough!

For the long-term operation of oil tanks, the risk of bottom leakage cannot be ignored. Once oil seeps into the soil and groundwater, it will not only cause economic losses but also lead to environmental penalties and potential safety hazards. Doing a good job in tank bottom anti-seepage is a key step for the compliant operation of oil depots and gas stations.

I. HDPE Geomembrane: The Core of Anti-Seepage, Impermeable to Oil

We select high-density polyethylene (HDPE) geomembrane, specially customized for oil tank scenarios:

• Super Anti-Seepage: Permeability coefficient ≤10⁻¹³ cm/s, effectively blocking the leakage of oil and oil pollution.

• Oil and Corrosion Resistance: Resistant to hydrocarbon, acid and alkali erosion, no aging or cracking during long-term use.

• Puncture and Tear Resistance: Adapts to tank foundation settlement, resists gravel puncture, and ensures a more stable structure.

• Easy Construction: Hot-melt weldable with tight joints, suitable for various tank farm sizes.

II. Filament Geotextile: Protective Partner, Stabilizing the Membrane

Used together with polyester filament geotextile, the protective effect is doubled:

• Isolation and Protection: Prevents gravel and sharp corners from puncturing the geomembrane.

• Drainage and Ventilation: Quickly drains accumulated water and gas under the membrane to prevent membrane bulging and sliding.

• Reinforcement: Improves the integrity of the foundation and reduces uneven settlement.

• Durable: Anti-aging and anti-microbial, with the same service life as the membrane.

III. Why Choose This Combination?

• Safe and Compliant: Meets the anti-seepage, environmental protection and fire protection requirements of tank farms.

• Long-term Cost-saving: One-time laying, long-term maintenance-free, reducing the cost of leakage rectification.

• Widely Applicable: Suitable for above-ground oil tanks, buried oil tanks, tank farm cofferdams, and anti-seepage renovation of gas stations.

IV. Our Advantages

• Direct Supply from Factory: Complete thickness and specifications, customizable according to engineering needs.

• Virgin Material Production: Qualified quality, with test reports provided.

• Supporting Construction Guidance: Mature welding technology, more reliable anti-seepage effect.
