Sprinkler Water Tank Repair - Northern Ireland

An internal ROV inspection of this sectional sprinkler tank showed that the mastic jointing  sealing the panel seams had perished

An ROV inspection of this fire sprinkler tank in Belfast was carried out at the instruction of our clients insurance company. The 10 year inspection showed that the mastic jointing at the panel joint seams had perished and that the Z purlins supporting the roof and vortex inhibitor were severely corroded.

Our client stored a lot of combustable materials on site, consequently their insurance company insisted that this fire water tank be in good condition and up to the job should a demand be made on it.

Our client stored a lot of combustable materials on site, consequently their insurance company insisted that this fire water tank should be in good condition and be ready for action should a demand be made on it.

The glass enamelled 'fused' internal wall surfaces were still in excellent condition. So we only needed to make repairs to the vertical and horizontal panel joints.

Before any application was made to the panel seams and internal steelwork , the surfaces had to be neatly keyed by abrasive grit blasting.

Before any applications were made we keyed the surfaces by abrasive grit blasting.

We always want to apply systems that we can guarantee watertight. So it was an easy decision to encapsulate all the vertical and horizontal bolted panel joints in a GRP lining and apply a zinc rich cathodic coating system over the steel work.

Cold Water Storage Tank Repair - West Midlands

These water tanks in this wonderful location were leaking and corroding badly. NDT testing showed the tanks surfaces needed restructuring to give them a new lease of life.

These cold water tanks in the Severn Valley were leaking and corroding badly. After non destructive testing/ NDT we restructured the internal surfaces with our fibreglass lining system to give them a new lease of life.

A scaffold platform was erected up to and around the tanks for safe access and egress. Consequently we worked safely de-sludging and grit blasting.

We brought in a local scaffolder to erect platforms up to the tanks for safe access and egress, enabling us to work safely throughout the refurbishment. Once the tanks were washed and cleaned, the surfaces were sand blasted with Hodge Clemco JBlast Supa.

Layers of woven and chopped strand fibreglass were applied to the blast cleaned and keyed internal surfaces, encapsulating all the riveted joints and completely restructuring the tanks.

After sandblasting and priming, layers of woven and chopped strand fibreglass were applied to the surfaces, encapsulating all the riveted joints and completely restructuring the tanks.

The cured fibreglass lining was completely sealed with an isopthalic gelcoat, protecting the surfaces for the next 25 years.

Fibreglass Tank Repair & Lining - Manchester

These fibreglass vessels were imported from Italy. One of them arrived damaged and failed pressure testing. As specialists in fibreglass repairs we knew we could guarantee our works successful and the tank would be back on line within a couple of days.

These fibreglass tanks were imported from Italy. One of them arrived damaged and failed pressure testing before going into production.

As fibreglass repair specialists, we knew we could carry out the repairs required, guarantee air tightness and get the tank back on line within days.

The stressed areas were very visible from inside the vessel. The complete wall and floor area was sand blasted to make a good key for all the fibreglass repairs and new fibreglass lining to adhere to.

The stressed areas were very visible from inside the tank. The 'spiders' were in random areas so it made sense to apply a reconstructive system to the complete wall/ floor area.

We carried out abrasive sand blasting to the internal surfaces to create a good key for the localised fibreglass repairs and new fibreglass lining to adhere to.

Layers of reconstructive fibreglass were applied to the leaking stressed areas. When the repairs had cured, a chemical resistant double layer fibreglass lining system was applied to cover all the internal surfaces and reinstate the vessels integrity.

Sprinkler Water Tank Repair and Fibreglass Lining - Sheffield

The internal wall surfaces of this 30 year old galvanised sprinkler tank were corroding badly causing it to leak persistently.

This 30 year old 'Galglass' fire sprinkler tank was leaking badly from random areas all around the tank.

The only repair system that was going to restore this tanks integrity and make it watertight was the application of our guaranteed for 25 year fibreglass lining system.

Originally, the only way into the tank was through the BVH on the roof. To create a safe working environment and improve access & egress we installed an access manway into the wall of the tank at ground level.

Previously the only way into the tank was from the roof, through the BVH (Ball Valve Housing) and then a ladder down to the tank floor. So to work safely inside the tank we installed a safety access hatchway into the lower wall of the tank at ground level.

Before any application the surfaces had to be abrasive gritblast cleaned. This process exposes the weaknesses in the substrate, highlighting the areas for repair.

Fist things first...the surfaces had to be cleaned and keyed by abrasive grit blasting. This process exposed all the weaknesses in the steel wall of the tank and highlighted the areas for repair...lots of them.

All the holes, badly corroded ares and panel seams were repaired using layers of reconstructive fibreglass. Once all the repairs had cured, a double skin fibreglass lining was applied to the complete wall surface area

After grit blasting, the surfaces were primed with polyester resin and all the holes, corroded areas and panel seams repaired and reconstructed using layers of fibreglass matting. Once all the repairs had cured, a double skin fibreglass lining was applied to the complete wall surface area, sealing onto the concrete floor all the way round the inside corner of the tank.

When the completed fibreglass lining had cured a coloured topcoat was applied to seal the whole system.

When the completed fibreglass lining had cured, a coloured polyester gel topcoat was applied to seal the whole system guaranteeing our works for 25 years.

A week after starting our works... we bolted up the access manway and the client put the tank back into service

Both tanks were opened, cleaned, closed, refilled and put back on line the same day.

Cold Water Storage Tank Repair - Birmingham

This badly leaking CWST/ cold water storage tank in the West Midlands needed a complete refurbishment.

This leaking cast iron cold water storage tank in the West Midlands needed complete refurbishment.

After removing the residual water and de sludging the water storage tank, the internal surfaces were grit blasted back to white steel.

As the tank was being fed by a bore hole there was plenty of sludge inside.

Once the sludge was removed, we cleaned and keyed the internal surfaces by sandblasting. Removing all the rust and exposing all the underlying weaknesses with the tank. We had to use Hodge Clemcos JBlast Supa sand blasting media to get the key we needed.

The many holes and eroded areas were repaired and reconstructed using layers of CSM fibreglass matting. Layers of fibreglass were applied over the previously made tank repairs and to the complete wall and floor surface area of the water tank.

The keyed surfaces were primed with polyester resin. When the primer was cured we repaired all the holes and reconstructed the corroded areas using layers fibreglass matting supported by gap filling paste and a WRAS approved polyester resin.

A polyester gelcoat was applied to the cured fibreglass lining ensuring water tightness and protecting the water tank against further corrosion for at least the next 25 years.

When all the repairs had been made and cured we applied the fibreglass reinforcement matting to the walls and floor area of the tank. The reconstructive fibreglass matting was impregnated with Lloyds approved polyester resin.

When the fibreglass lining had cured, a polyester gel topcoat was applied to the surfaces sealing the lining and ensuring water tightness.

Oil Tank Repair - Middlesborough

The steel bases of these bulk storage oil tanks needed repair and sealing with fibreglass to restore and protect against further corrosion.

These light oil storage tanks in Teesside were corroding badly around the annular ring/ external apron. They needed immediate attention to protect them against further corrosion and the possibility of the tank leaking oil into the bund.

The steel tank base and concrete apron was sandblasted clean and keyed to take the fibreglass application.

The steel wall of the tanks and concrete aprons were sandblasted to key to take the fibreglass application.

The fibreglass lining was applied up the tank base and encapsulates the concrete plinth to ensure rainwater run off.

We applied our reconstructive fibreglass lining system up the tank wall and across the concrete plinth to ensure complete rainwater run off.

This full proof and long term system was applied to both tanks in this oil bund in Middlesbrough.

This long term solution was applied to both tanks in this oil storage bund in Middlesborough.

Water Treatment Works Tank Repairs and Epoxy Coating - Nottingham

These settlement tanks needed a full upgrade and refurbishment to maintain their watertightness.

These concrete waste water tanks were no longer holding water and needed repair and refurbishment. The overall condition of the concrete was good, apart from few settlement cracks at the internal corners and the expansion joints needing re sealing.

After sand blast cleaning we could see that the concrete surfaces weren't in that bad a condition. There were a few cracks that we mastic sealed and bridged with fibreglass and others we had to make concrete repairs to.

After preparatory sandblasting we carried out the necessary concrete repairs and mastic sealing using Sika products.

We were lucky with this contract, we had great weather for the whole week?.?

Chemical Resistant Fibreglass Bund Lining - Leeds

Chemical bund Glasgow

This concrete block constructed chemical bund was not holding water so there was little doubt it would contain any chemical spill.

Chemical resistant fibreglass lining

After preparatory sand blasting we applied layers of fibreglass matting to the surfaces and impregnated them with chemical resistant vinyl ester resin.

Braithwaite Tank Repair and Fibreglass Lining - South Wales

These pressed steel Braithwaite water tanks were starting to leak in places.

The sectional panel joints were leaking in this 'Braithwaite' water tank. Our client had been making welding patch repairs over the leaks from the outside. This practise was becoming impracticable and they wanted a repair system that would last for at least the next 20 years.

The original factory bitumastic coating was breaking down and the exposed internal steel surfaces were rusting badly.?

The tank was drained and inspected. It was found that the original factory bitumastic coating was breaking down and leaving the steel substrate exposed, ultimately causing the surfaces to corrode. Because of the condition of the tank is was decided to apply a reconstructive fibreglass lining covering the internal walls and floor.

The completed cured application was topcoated with a waxed polyester gelcoat/ flowcoat.

The internal surfaces were all keyed by sand blasting. The sand blast prep removed what was left of the original bitu coating. A specialist resin primer was applied to the cleaned surfaces before the repairs were made and the fibreglass lining system applied to the walls and floor surfaces.

Fibreglass Wine Tank Modifications - Manchester

These existing 30 year old fermenting vessels in Manchester were being upgraded and having aeration systems fitted inside them. The tank walls needed thickening in places to be able to handle the new intrusions.

Sprinkler Water Tank Repair - London

This Franklin Hodge sprinkler water tank in London was leaking from all the wall panel joints and bottom corner because the butyl rubber 'bag' liner was holed and letting the water behind it.

This Franklin Hodge 'Firestore' sprinkler water tank in the basement of a central London office block was leaking from the bolted sectional panel joints

The butyl 'bag' liner inside the tank had perished with age and was floating inside the tank, meaning the whole system would have been useless should there have been a demand on the tank for putting out a fire.

The tank was being constantly topped up at the ball valve because of all the water leaking out of it.

We accessed the tank and cut the butyl rubber liner into manageable sizes and removed them from the tank. We could have installed a new liner but the client wanted a system that we would guarantee of 20 years because of the local environment.

We safely accessed the tank and removed the butyl rubber liner. Cutting it into manageable pieces that we removed safely from the tank. We could have installed a new rubber bag liner, but our client wanted a watertight system that would last 'forever' and guarantee they didn't have the same problem again.

We sand blast prepped 150mm either side of the panel joints? to key the galv surfaces and applied our fibreglass lining system over the keyed areas to seal all the joints.

We carried out preparartory sandblasting to the steel & concrete surfaces 150mm both sides of the panel joints.

After priming we applied our watertight fibreglass lining system over the keyed areas to seal all the joints.

Grain Silo Repairs - Sussex

Img 0046

As you can see we lucked into a good week of weather to repair these grain silos.

Img 0045

Access and egress from inside the silos was safe and made the project less of challenge.

Img 0040

The drying floors sat up about 500mm from the concrete floor and had to removed.

Img 0038

The wooden supports were also removed to make the job a lot more doable

Img 0039

Once all the floor was removed, the damage was very visible. The internal wall floor corner had rotted out and was letting rainwater and vermin in from the outside.

Img 0044

After sandblasting the corrugated tin wall and concrete floor, we applied our fibreglass lining system. This ensured the grain in these silos was never going to get wet again and also protected the stock from vermin.
