Gas Stations
Revision at filling stations
Keeping tanks and manholes clean is the basis for maximum quality and safety. Frequent causes of problems: civil engineering work, ageing manhole covers, water ingress, defective pipe penetrations, corrosion. The critical points are the manholes, covers and their inner workings.
The following factors can massively impair the operational safety of your system:
- Leaks due to conversions or surfacing work
- Obsolete or defective manhole covers
- Water ingress and contamination in the spaces between shafts
- Defective cable ducts in the inner shaft
- Corroded pipes and screw connections
- Missing or defective access covers (e.g. filling or dipstick lines)
We look beyond mere tank cleaning: the critical interfaces – manholes, covers and their inner workings – are the real problem areas.
Only those who strategically into maintenance of this key infrastructure will secure its market lead for the next 20 years. If this is neglected, escalate the consequences – the repair of damage (such as engine defects) exceeds the preventive maintenance costs many times over.
tank and in turn develops a galvanic element, which sooner or later leads to corrosion in the tank. This sludge can also develop into a fungus-like substance (primarily with diesel oil), which can lead to filter blockages in vehicles.
Particular attention must be paid to the manhole cover and the “inner workings” of a manhole at filling stations. Moisture or even water are extremely aggressive, especially in combination with gasoline gases, which leads to considerable corrosion.
Tank inspections also include testing safety equipment such as filling safety devices, vapor recovery valves and reporting to cantonal authorities.

Refurbishment
Reasons for refurbishment:
A leak alarm on a double-walled underground tank (standard today) usually signals corrosion damage. This is often caused by water penetrating the shaft or by age-related fatigue of the outer wall. Corrosion inside the tank, on the other hand, is less common.
Our solution approach:
Corrosion damage in the shaft can often be repaired by targeted welding, but this requires prior decommissioning. Defects on the inner or outer tank shell must be rectified by an innovative upgrade: Either by means of coating, the installation of a tank-in-tank system or an inner tank shell.

New tank system
Do you have any questions or would you like a personal consultation? Contact us – together we will find the best solution for you.
The construction of new tank facilities requires project planning with maximum focus. Thanks to our in-depth expertise, we navigate you through the entire cycle: we start with the initial needs analysis, clarify all the necessary details regarding geology and water protection and efficiently carry out the planning and construction work.
Whether it’s a highly frequented roadside filling station, a works filling station for your fleet or a specialized supply solution at an altitude of 2,000 metres – we implement the systemic, tailor-made solution for every demanding project, exactly according to your specifications.
Decommissioning
Professional decommissioning of gasoline tanks
Petrol tanks may only be decommissioned by specialized personnel.
Our work steps:
Controlled flaring of the residual gases (see picture)
Removal of residual oil and sludge
Flushing the product lines
Disposal of the antifreeze (for double-walled systems)
- Safe blanking of the filler neck

Frequently asked questions
When is the ideal time to clean the interior?
Heating oil tanks should be inspected with internal cleaning every ten years.
The last revision date: Where can I view it?
The date of the last work carried out can be found on the audit sticker on the tank compartment door.
Are the costs higher for inspections in winter?
No. We will provide you with a temporary heating system free of charge.
What is the maximum number of liters that can be removed without additional costs?
Maximum 15,000 liters.
