Recent Projects Oil Tank Repair - Middlesborough These 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. The steel wall of the tanks and concrete aprons were sandblasted to key to take the fibreglass application. We applied our reconstructive fibreglass lining system up the tank wall and across the concrete plinth to ensure complete rainwater run off. This long term solution was applied to both tanks in this oil storage bund in Middlesborough. Cold Water Tank Repair - Birmingham This leaking cast iron cold water storage tank in the West Midlands needed complete refurbishment. Our job was to bring it back into the 21st century. 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 Clemco's JBlast Supa to get the key we needed. The cleaned surfaces were then 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. When all the repairs had been made and had 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 applied fibreglass lining had cured, a topcoat of polyester gel was rollered on the surfaces to seal the lining, ensuring water tightness and protecting the water tank against further corrosion for at least the next 25 years. Cold Water Tank Repair - Worcester 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. 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. 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 gel topcoat protecting the surfaces for at least the next 25 years. Sprinkler Tank Repair - Belfast An underwater 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 roof stanchion 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 should always be ready for action should a demand be made on it. As the glass fused wall surface area was still in excellent condition we carried out the repair to the vertical and horizontal panel joints. 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 with a fibreglass lining system and apply a zinc rich cathodic coating system over the steel work. This picture shows the full encapsulation of the sectional panel joints using our guaranteed watertight fibreglass lining system. It was very wet and cold in Belfast when we were there, so we got a big indirect diesel heater to help the job along. Thanks to HSS in Belfast for the heater and generator hire. Fibreglass Tank Lining - Manchester These fibreglass tanks were imported from Italy. One of them arrived damaged and failed pressure testing before going into production. As fibreglass specialists, we knew we could carry out the repairs required, guarantee airtightness and get the tank back on line within days. 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 stressed areas. When the repairs had cured, a chemical resistant double layer fibreglass lining system was applied to cover the complete internal surface area and reinstate the tanks integrity. Sprinkler Tank Repair and Fibreglass Lining - Sheffield This 30 year old 'Galglass' fire sprinkler tank was leaking badly from random areas all round 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. 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 an access hatchway into the lower wall of the tank at ground level. 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. 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 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 new access manway and the client put the tank back into service. Grain Silo Repairs and Fibreglass Lining - Suffolk These corrugated grain silos in Suffolk were badly corroding where the silo wall meets the ground, consequently allowing water and wildlife into the silo from the outside. From inside the silos, daylight is very visible where the internal corner had rotted out. The internal wall floor corner was sandblasted to create a good key and sealed by applying our fibreglass lining system. This guaranteed that the stored grain would be kept dry and no water or wildlife could damage the goods within. Wastewater Tank Repair - Northern Ireland The internal corner on these effluent tanks had broken down and needed replacing. Project Linings Ltd were contracted to remove the cracked and delaminate epoxy floor and replace like for like. The concrete floor surfaces were cleaned and keyed by grinding all the way round the inside corner of the tank. The internal corner was resealed with Sika TS plus and the concrete floor primed with our epoxy concrete sealer. Two coats of resistant glass flake epoxy were then applied over the primed concrete surfaces. The tank was bolted back up and back in service within the week. Underground Diesel Tank Cleaning - London With all the health and safety in place and wearing the right PPE for the job, we carried out the cleaning of two underground diesel storage tanks. Our client had run down the tanks to virtually empty, making ready for us to open the tanks and pump out the residue. Project Linings' operatives safely accessed the tanks and washed down the internal surfaces with specialist detergents. All the dirty diesel and washings were removed from the tanks and safely disposed of, off site. Both tanks were opened, cleaned, closed, refilled and put back on line the same day. Water Treatment Works Tank Repairs and Epoxy Coating - Nottingham These wastewater tanks were no longer holding water and needed complete refurbishment. The overall condition of the concrete was good, apart from settlement cracks at the internal corners and the expansion joints needing re sealing. After preparatory sandblasting we carried out the necessary concrete repairs and mastic sealing using Sika products. We were lucky with this project, we had great weather for the whole week. Perfect conditions for applying our specialist epoxy coating system. Chemical Resistant Fibreglass Bund Lining - Leeds This concrete block constructed chemical bund was not holding water so there was little doubt it would contain any chemical spill. 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 The sectional panel joints were leaking in this 'Braithwaite' water tank. Our client had been making 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 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 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 fibreglass 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. We reconstructed the areas with layers of fibreglass where the new stainless pipework was going to pass through the tank walls and be tightened on both sides. Effluent Tanks Repair with Mastic Sealant - Bristol These stainless steel effluent tanks needed all the sectional panel joints mastic sealed with Sikaflex TS Plus to ensure watertighness. The stainless wall had to be chemically primed and the concrete floor mechanically prepped and primed. Sprinkler Tank Repair - London This Franklin Hodge 'Firestore' sprinkler tank in the basement of a central London office block was leaking from the bolted sectional panel joints The rubber 'bag' liner inside the tank had perished with age and was letting the water in behind it. The butyl liner 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 removed the 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 carried out preparartory sandblasting to the steel & concrete surfaces 150mm both sides of the panel joints. then after priming we applied our watertight fibreglass lining system over the keyed areas to seal all the joints. This Franklin Hodge sprinkler water storage tank was back into service within the week. Grain Silo Repairs - Sussex As you can see we lucked into a good week of weather to repair these grain silos. Access and egress from inside the silos was safe and made the project less of challenge. The drying floors sat up about 500mm from the concrete floor and had to removed. The wooden supports were also removed to make the job a lot more doable 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. 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.
