Due to the Growing popularity of conversions of aga cookers from oil to 13amp electric, we will no longer be installing Oil Tanks.

Solid Foundations Are Key

Having the correct foundation for any oil tank installation is essential.

As with many things these days, in order to remain competitive, unscrupulous installers are skimping on quality and taking short-cuts.

That’s not the Fournier’s way!

Any Oil Tank must have a suitable base.

For Safety and Environmental reasons, it is vital that foundations give the correct support to your tank.

If you are unsure about your present foundations, you should have them checked by a professional.

Founier’s are here to help!


The correct installation method

The foundations for an oil tank should be:

  • Adequate for the weight of the tank
  • Non-combustible
  • Free from cracks and imperfections
  • Level
  • Constructed of concrete, paving stones or stonework
  • Large enough to extend 30cm beyond all sides of the tank

Our foundations often take a couple a days to dig and use traditional concreting methods. Our concrete bases sit on compacted stone, with steel reinforcements set into the concrete.

As seasons change the underlying ground conditions can change substantially and it is vital that this movement is not transferred to the tank. Inadequately support, will leave the tank weakened, leading to the eventual failure and escape of the stored fuel.

A Fournier’s base means your tank is protected and should be safe for decades to come.


Sub-standard Foundations

  • Fast setting concrete
  • Inadequate for the weight of the tank
  • Too small
  • Not level or unstable

Sub-standard foundations and fast setting concrete are highly prone to cracking; especially when winter frosts set in. This causes shifting that can cause stresses and fractures within the tanks structure. Once compromised, damage will accelerate and if left unchecked or unnoticed, this could leave you with a clean-up bill often approaching the value of your property.


Surveyor’s Report

If you try to sell your property, a mandatory surveyors report will highlight:

  • Sub-standard workmanship
  • Regulation discrepancies
  • Present tank condition and future potential weakness
  • Cracks in the foundations

This could knock a significant percentage of the re-sale value and scare off all but the very keen. The sale process will be drawn out, with buyer relations strained to breaking point.
That’s a story that we have heard too many times.

To cut costs, our competition are using small block pillars and one day fast setting concrete. There’s less skill required and in the short term, time is saved. That simply isn’t good enough and given a couple of years you’ll be landed with a bill.


Oil Supplier

If your oil supplier spots foundation cracks or tank damage, they can refuse to re-fill your tank and you will be left without oil. Any remaining oil within the tank will need draining. The tank will need replacing and the failing foundations broken up and removed. Hopefully, you won’t be left with a massive environmental clean up bill.

Questions to ask your installer

  • Will you be using fast setting concrete?
  • What are the dimensions of the tank and how big will the base be?
  • Are you using compacted stone foundations?
  • Are you using steel reinforcements?
  • Do you have photos of similar installations?
  • Are you OFTEC registered?

If you are unhappy with any of their answers, seek professional advice. As with any installation, price isn’t the primary factor it is quality.
