A Domestic Water Tank in San Francisco Needs Proper Lining

There are hundreds of domestic water tank in the San Francisco area and thousands in use across the great state of California. And it is no wonder. There are many uses for water storage tanks including potable water, stormwater, wastewater, and fire protection. Commercial applications for water tanks include agriculture, petrochemical, wineries and vineyards, and food processing. Thus, San Francisco domestic water tank maintenance and repair work is an important business enterprise.  Read more »

San Francisco Water Tank Repairs

Commercial steel tanks have a limited lifespan. Whether it’s from corrosion, performance failure, or unexpected damage, steel tanks often require tank leak repair. Making repairs to steel tanks can be expensive, time-consuming and expensive, especially when steel tanks are buried underground. Whatever type of repairs your steel tank needs, consider fiber-reinforced plastic (FRP) as an efficient way to get back to normal. Here are three common types of San Francisco water tank repairs.

Water Tank liners  Using FRP for Tank Repairs & Protection

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 »

Fiberglass Tank Repairs Made Simpler

According to the United States Environmental Protection Agency, approximately 587,000 underground storage tanks were being used to contain petroleum and other potentially hazardous materials as of March 2012. These tanks have an expected lifespan of 30 years, but many will only last around 20 years before they start to leak or show other signs of wear and tear  and require fiberglass tank repairs. The EPA began to implement strict regulations on underground storage tanks in 1984, and many of the tanks in use are double-walled to prevent leaks. Unfortunately, not even the most stringent regulations will prevent leaking and other signs of damage completely. Even the sturdiest and most secure water tank liners need to be repaired or replaced eventually, which used to always involve a complicated and costly excavation process. Read more »

Fiber-reinforced polymer (FRP) is a composite material that is composed of a polymer matrix reinforced with fibers. The composite material can be high-strength fibers like glass or carbon, or steel wires that are embedded in a polymer matrix. The FRP repairs use fibers to provide strength, and the polymer matrix serves as a binder, protects the fibers, and shares the load among the fibers. FRP composites have been in use in the United States for over 30 years. Today, FRP is widely used in many industries and in many applications including FRP ducts, FRP wraps, and FRP repairs.  Read more »
