Success story

Reinforcing earth around underground oil tanks should keep them safe for 100 years

PROJECT OVERVIEW

How Enka solutions helped a crude oil facility stay stable, secure and out of sight.

Project required strong, durable earth structures

When building large underground crude oil tanks in Loukov, the Czech Republic government had many issues to face. The installation had to be safe, stable, long-lasting, economical and maintenance free – and all with minimal disruption to the surrounding environment and view. A key element of its design involved walling the tanks off with a backfilled soil structure, ensuring there was no earth contact pressure against the walls.

Enka solution delivers reinforcement and erosion control

The challenge of supporting these soil structures was solved by Enka solutions. Geotextile Enka-Force G reinforced the vertical soil walls while providing an effective soft facing. Geogrid Enkagrid G strengthened the slopes of the embankment that would help conceal the facility. Enkagrid G and Enka-Net supplied erosion control for the embankment and tank domes.

APPLICATION

Urban Development

Flexibility and fast, easy installation

The combination of these Enka products provided a complete solution, balancing price against long-term performance. Service life is expected to exceed 100 years. The flexibility of the woven geosynthetics and their wide roll sizes made for fast and easy installation, in all weathers. Around 300,000m3 of excavated soil could be reused. This also helped minimise the environmental impact of a project that will enable government-owned distributor CEPRO a.s. to significantly improve oil supply to the eastern part of the country.
