Cooling Tower Lining

Cooling tower lining, repair and upgrades with GRP

If cooling towers aren't properly coated, they will begin to fail. If they're made of stainless steel, they can begin to leak at the joints. If they're made of mild steel, they can corrode too – and both can provide a breeding ground for legionella.

Cooling tower ponds take particular punishment, and less durable coatings like epoxy are prone to fail. A fibreglass lining eliminates the problem, creating a 'pond within a pond' that can last for decades.

Safe, long-lasting fibreglass linings

GRP cooling tower linings are safe and long-lasting, and can remain maintenance free for many years.

A GRP lining seals and prevents leaks at the joints between sections, handles normal structural movement well and is a cost-effective way of lining your cooling towers to the highest industrial standards.

Protect staff from harmful bacteria

The resins we use for lining your cooling towers meet BS:6920 standards and have been subjected to a range of microbiological growth tests to ensure that our GRP linings do not support the growth of harmful bacteria, including Legionella Pneumophila (the source of Legionnaires' disease).

We'll prepare the internal surfaces of your cooling towers and then apply a fibreglass lining that will keep them in perfect condition for years to come – on time and on budget.

Health and Safety

Our commitment to health and safety is one of the primary reasons we have been entrusted to work on high risk establishments such as nuclear plants, chemical factories and railway stations.

Put these problems behind you with a fibreglass lining for your cooling towers...

Contamination & legionela

Our GRP liner has been tested to ensure it does not support microbiological growth. So when you ask us to line a cooling tower, we help maintain a safe cooling system – which reduces the risk of infections such as Legionnaires' disease.

Corrosion & leaks

Scale, corrosion and leaks – problems which can in turn lead to the deterioration of your towers, higher costs and unreliable cooling. But if you ask us to coat the inside of your cooling towers with our fibreglass lining, they'll be in top condition and maintenance-free for years to come.

Interior deterioration

Many factors can cause the lining of your cooling towers to deteriorate over time – which can lead to further problems down the road. Just ask us to apply our fibreglass lining for a tougher and longer-lasting internal coating that will weather even the toughest conditions.

Insecure structure

Over time, the mastic between the joints of the tower can fail, causing fissures and leaks from these areas – which can prove disastrous. Fortunately, our fibreglass lining copes well with normal structural movement and because we build a now sweamless 'pond' within the old, there are no joints to leak.

Cooling tower repair guide

Cooling towers ensure the quality and temperature of air circulating throughout a large building. They draw in air, cool it using water, and then distribute it through a building via a network of pipes. But because cooling towers components are made of metal, they are at threat of corrosion...

Over time, original linings can wear away, leaving the metal exposed to water. This can result in a range of problems including the growth of harmful microbiological organisms like legionella that can be spread through the ventilation system of a building.

This can make cooling systems unsafe – and even illegal.

However, it's simple to avoid this problem by coating the inside of your cooling towers with a fibreglass lining. This won't react to water, doesn't encourage the growth of unwanted bacteria and can last for decades.

What can cause a cooling tower to fail?

In mild steel cooling towers, the most common threat is corrosion due to the failure of an inadequate coating. Stainless steel towers can also fail at the joins.

Unlike fibreglass, non-approved paint such as an epoxy coating or bitumen doesn't have the strength, longevity or chemical resistance to keep your cooling towers safe and secure over time.

Both corrosion and joint failure can result in expensive replacement costs and result in micro-bacterial growth that can prove harmful to to staff working in the buildings serviced by the cooling towers.

Why use fibreglass to line a cooling tower?

A fibreglass lining is the best way to protect your cooling towers and ensure they last longer and require less maintenance. It also has the added advantages of being:

  • Corrosion Proof
  • Micro bacteria resistant
  • Leak free
  • Flexible

Do your cooling tower linings and repairs meet regulations?

Yes. Our GRP linings are approved by the Water Regulations Advisory Scheme as well as the Drinking Water Inspectorate – each of which has independently tested out linking to ensure it's resistant to the growth of harmful bacteria and safe to use in cooling towers.
