Storage Tank Waterproofing
Design, Materials, and Maintenance Considerations
Whether a storage oil tank is waterproof depends on its design, material, and construction, but most standard models are engineered with waterproof features to protect stored oil and maintain tank integrity.
Why Waterproofing is Essential
- Water contamination can ruin oil quality
- Moisture causes corrosion inside the tank
- Leads to sludge buildup and reduced efficiency
- Above-ground tanks have sloped tops to direct rainwater away
- Underground tanks use additional waterproof coatings
Material Impact on Waterproofing
Steel Tanks
Coated with anti-rust and waterproof layers like epoxy or zinc to block water penetration effectively.
Fiberglass Tanks
Inherently waterproof with non-porous structure that prevents water seepage without extra coatings.
Plastic Tanks
Made from high-density polyethylene, these tanks don't absorb water and resist cracking from moisture.
Long-Term Maintenance Considerations
A tank's waterproofness can degrade over time. Wear from weather, physical damage, or aging of seals may create small gaps where water can enter. Regular maintenance is therefore important—inspecting for cracks, checking seal integrity around lids or valves, and reapplying waterproof coatings when needed helps preserve the tank's waterproof properties.
In short, while storage oil tanks are designed to be waterproof, their long-term performance relies on proper material selection and ongoing upkeep.
