Tank leak testing and remediation with plastic lining

Air, vacuum and hydrostatic tank testing to EN 13160. Remediation of damaged above-ground and underground tanks using the plastic lining method — service life extended by 17+ years. Technical inspection certificate, since 2009.

Tank testing and remediation
since 2009

Tank leak testing is a legal requirement for all above-ground and underground fuel tanks in North Macedonia. The Inspectorate requires proof of tightness before commissioning, during technical inspections and after remediation work. Our team carries out all the standard tests — air pressure, vacuum and hydrostatic — in line with EN 13160 and the regulations of North Macedonia.

With 17+ years of experience we work with all types of tanks: ASTs and USTs for petrol stations, industrial tanks, heavy fuel oil tanks and heating tanks. We issue certificates accepted for technical inspection, by the Water Protection Inspectorate and for internal ISO procedures.

For tanks where the test shows damage, we offer remediation using the plastic lining method — we fit an internal plastic lining that extends the tank's life by 17+ years, without the need for costly replacement. The process complies with EN regulations and is certified for fuel, water and industrial liquid tanks.
