What is a tank lining? I’m guessing if you have got this far and reached our website you are either interested in having one completed or you are researching about a potential lining. To keep things simple a lining is the building of a new tank inside the current one that may have deteriorated either by corrosion or chemical erosion.

Linings can be reinforced such as GRP (glass Reinforced Plastic) or un- reinforced such as an Epoxy, polyurethane or Polyurea.  All of these Linings have a sole purpose and that is to prevent whatever is being stored in the storage tank to stay in there for good.

Losing a stored chemical can be costly and very bad for the environment and should a spill or a catastrophic failure occur Environment Agency can place large fines on companies.  Normally when a leak occurs we cannot physically see because normally tanks are buried under ground. In these instances, regularly checking liquid levels and monitoring for losses is essential.

So you have a leaking tank, the first thing to prioritise is the environmental impact, can the leak be contained in secondary containment i.e. spill trays, bunds? Is the chemical leaking dangerous for human contact? A leaking water tank is not as much a priority as a leaking caustic acid tank however put into context being on a water meter and you are losing 500 litres of liquid per day the longer this is left the costs soon build up. So in essence our advice if you have a leak get it looked at ASAP ok you will still have to spend money to repair the leak but in the long run you will save by getting it done sooner rather than later.

We have a vast experience in repairing leaking tanks both from a perspective of liquid entering a tank i.e. groundwater, and egress of chemicals/ water from a tank. Ingress of groundwater has a tendency to occur below ground installations whilst egress of chemicals/water tends to occur above ground normally due to corrosion or chemical erosion, the second is a much easier situation to deal with than the first. Linings do not like water, groundwater likes to find a way in to tanks, tanks stored underground need to be able to withstand groundwater pressures. Over the years what SLS have found is that tank manufacturers are using less materials in their creations of their tanks and informing their customers that are fit for purpose when they are clearly not.

Lining a damaged tank is much more cost effective than the removal and replacement of an old one. Can be carried out from as little as 25% the cost of a new one. Even getting a new tank lined is good thinking and gives you peace of mind that your chemical/water is stored safely.

Confined Spaces are a taboo in the industry, SLS have fully trained staff with City & Guilds Training and all the rescue equipment and the essential know how to carry out their linings in confined spaces!
