Corrosion is a chemical reaction that occurs on the surface of different materials, especially metals. Most people are familiar with rust, which is probably the most common type of corrosion. Corrosion is considered a natural process that transforms the metal into undesirable substances. When you have storage tanks, rust is an enemy. Fiberglass liner repair and fiberglass tank liners can help prevent corrosion and keep your equipment in service longer. Read more »
We were called upon by a condo building manager in San Francisco to remove their old commercial water tank lining, perform tank linings repair and surface preparation, and reapply a new tank lining.

Sure, there are some common issues that come with steel tanks and tank linings that simply cannot be avoided. The key is to get tank repairs and tank liner repairs right away- before small issues can grow into major problems. Read more »
Metal storage tanks are extremely susceptible to corrosion, and there will come a time when they will need to be repaired or replaced. Replacing a storage tank is sometimes unavoidable, but it is also a much more costly option. In most cases, it’s best to stick with water tank repair unless the bottom of a tank is no longer salvageable. This usually involves installing new water tank liners, which have evolved over the years to be far stronger and more resistant to heat and corrosion than they’ve been in the past. This is largely thanks to FRP. Read more »
Steel and concrete tanks have always been used to store potable water and other liquids, which means corrosion has always been an issue. In the past, companies have tried to prevent corrosion and avoid costly water tank repairs by lining tanks with materials such as lead-based paint, vinyl, and coal tar epoxies. These days, most companies use fiberglass-reinforced polymer, or FRP, for their water tank liners. FRP was introduced in the 1950s as a way to repair tank bottoms that had corroded. The material could not only bridge gaps that had formed in the bottoms of tanks, but they provided protection from internal corrosion as well. This made FRP wraps useful in tanks that were being used to contain more caustic chemicals. Read more »
Above ground storage tanks are subject to corrosion. The bottoms of these storage tanks are especially vulnerable. Not only do soluble salts and chemicals settle to the bottom of the tank to damage the internal surface, but the external surface can be damaged by salt water, soil and other contaminants. The solution used to be replacing the bottom of the tank, which is expensive and time-consuming. Another option is to make FRP tank liner repairs, coating the tank with a fiberglass reinforced plastic lining (FRP) that is considered a secondary bottom. It’s almost like a tank liner, but it’s sturdy and durable to give you another 10 to 20 years out of your tank. Read more »
Fiber Reinforced Plastic (FRP) is widely used in many industrial applications. FRP refers to a composite material, a plastic (polymer) matrix that has been reinforced with glass fibers which in combination result in a material that is exceptionally strong but also flexible. FRP materials are used in products and components that must be precisely engineered with tight tolerance limits, a low fatigue index, and high impact tolerance. FRP ducts, piping, and FRP tank liners are examples of excellent FRP applications. Read more »
