Fire Sprinkler Tank Lining & Repair

WRAS Certified & DWI Listed
20 Years In Business

Fire sprinkler tanks are often susceptible to corroding as their metal substrate is not always protected during installation. This can be due to the original coating breaking down or liners failing to function correctly, which can lead to a loss of water from leaking. Our exceptional lining and repair service can correct this issue. The aim with our refurbishments is to restore your tank to the condition it was when originally installed, with our work applicable with tank approval criteria.

We offer our service on various types of sprinkler tanks from steel sectional, GRP and concrete structures, so we can find the right fix for the material of your tank. Whether your tank just needs relining or a full refurbishment our fully qualified and certified team will be able to provide a long term solution to solve the problems with your tank. Our refurbishment complies with LPC rules for automatic sprinkler installations 2015.

CONCRETE FIRE SPRINKLER TANKS

Concrete fire sprinkler tanks may be prone to leaking as water can find its way through weaker areas of concrete substrate where cracks fissures and blowholes are present. If left untreated these issues can become very serious so it is essential that concrete fire tanks are refurbished if they have faced any corrosion.

In this instance we refurbished a concrete fire tank sized at approximately 10m x 3.4m x 2.5m located partially underground at a hospital in Scotland. There was evidence that the tank was leaking, therefore we suspected that the existing ‘render’ had ‘popped’ due to ingress of water and water was finding its way through the weaker areas of the concrete substrate (i.e. cracks, fissures and blowholes). If left untreated the problem would have escalated to more catastrophic proportions.

GRP FIRE SPRINKLER TANKS

GRP fire sprinkler tanks will need to be refurbished if the substrate breaks down, as this can lead to leaking if the mastic fails to function properly. Our excellent refurbishment service can ensure that your tank is resistant to these problems by using our COVAC coating system.

On this project we worked on a GRP sectional water retaining structure, sized at approximately 10m Long x 6m Wide x 3m High. The structure has an internal, divisional, GRP wall which ‘splits’ the structure into 2 compartments, each sized at approximately 10m x 3m x 3m. One compartment was currently full of water, whilst the other had remained empty for approximately two years, due to numerous leaks from the joint areas where the mastic between the panels had failed. In an attempt to stop the leak, the bolts had been over tightened, however, this just resulted in the mastic being further squeezed out and exacerbating the problem. The Client requested that both compartments were relined as the compartments were the same age, the full compartment was very likely to also fail in the near future.

STEEL SECTIONAL FIRE SPRINKLER TANKS

Steel sectional fire sprinkler tanks can become severely corroded which can lead to the metal substrate breaking down. However, with the excellent refurbishment service COVAC offer you can avoid witnessing these problems with your tank.

This project involved a steel sectional fire sprinkler tank made from 4’ x 4’ steel, profiled panels and internal steel bracings. The tank is sized at approximately 20’ x 12’ x 12 and located in a shopping arcade in Warwickshire. The internal surfaces of the tank had been previously coated with bitumen which had reached the end of its useful life due to sub-film corrosion, low film build, general deterioration and subsequent de-bonding. Although there was evidence of significant corrosion, the tank was structurally sound and after our full relining service has many more years of trouble free service ahead.
