A sustainable alternative to replacing your tank
If a leak occurs, part of your tank contents — and thus also part of your working capital — will drain away without you noticing. A waste of money, plus a heavy burden due to the mandatory clean-up of the contamination caused. Why not just replace the tank? Then you face mandatory cleaning-up costs and high structural costs for installing a new tank — and the law states that an unused tank may not just remain in the ground.
Cibor has an alternative for you: converting your existing tank into a double-walled tank, possibly repairing it, or lining it. After processing, you safely continue using your existing tank. You enhance your image as an environmentally-friendly company — your tank is renewed, fully in accordance with the current environmental legislation, and still affordable.

Does your tank still satisfy the environmental legislation?
Double wall
3. Double-wall leak detection
Cibor installs leak detection systems with a double tank wall and converts your buried single-walled tanks into double-walled tanks.
Continuous monitoring
Continuous monitoring of inner and outer wall.
No environmental pollution
In case of a leak, the second wall prevents environmental pollution.
Accessible outer wall
The outer wall remains accessible for any repairs.
Made-to-measure inner wall
Placed via the man hole and inflated under pressure so it perfectly assumes the shape of your existing tank.
Vacuum leak detection
A leak detection device creates a vacuum between tank wall and membrane — drops below alarm level in case of a leak.
Acoustic and visual alarm
You know there is a problem and can take measures — the double wall ensures the product cannot escape.
DOPA system
4. Coating and double-wall conversion of petrol and chemical tanks
For petrol tanks and tanks for the storage of chemicals, Cibor offers the DOPA system: a permanent leak detection system with double barrier. After cleaning, degassing and internal inspection, a protective glass-fibre reinforced lining can be applied as mechanical reinforcement. A preserving 2-component lining with extremely high chemical resistance is applied with a special Airless spray device, followed by a spacer and a laminated glass-fibre second artificial inner wall.
A vacuum of up to 800 mbar in the gap checks the airtightness of both walls — permanently monitored by an Eex-leak detection device. False alarms are ruled out: the alarm is only activated if one of the two walls leaks. The DOPA system was developed in Switzerland and has proved its worth for more than 25 years — the oldest Belgian installation dates from 1994, certified more than 10 times by SGS, with prototype approval for Flanders and widely used in Brussels and Wallonia.
