Structural tank
Made of steel or reinforced concrete (1) to take up the static loads,
tailored to the specific liquid to be stored and the local conditions.

    First hazardous material tank
Medium and aging-resistant GRP tank made with high-quality materials: Double polyester resin coating with textile glass mats (2), double polyester resin sealing (3), impermeability tested with high voltage (25,000 volts).
 
    Interstitial space
Hollow cavity between the tank skins, which is made using a ball-impact metal foil or a spacer fabric manufactured and continuously monitored by
a vacuum leak detector.

 
    Second hazardous material tank
With layered coatings identical to the first hazardous material tank for doubled safety and continuous leak monitoring.

Polyester resin with textile glass mats is manually applied in several layers to the tank. The thickness of each skin of a tank for hazardous materials is at least 3 mm. Depending on the medium to be stored, the tanks made in this fashion can also be equipped with an electrically conductive top coat.
All tba tanks are subject to strict internal company and governmental building inspections. tba has developed and built hazardous material tanks since 1963. Up to now, more than 400 tanks have been built, with a total volume of 600 million litres.
