Materials used in hydraulic engineering and earthworks are typically dimensioned and designed to last through decades. Over long periods of time, they absolutely must not lose their specific properties. In order to meet such challenging requirements, the products of choice are for the most part made of plastic or modified plastic.

Plastic sealing sheets are commonly used in the construction of waste disposal sites, tunnels, roofs, and for water protection purposes. Geosynthetics, on the other hand, such as geotextiles, geogrids and composite products, are a replacement or supplement to traditional mineral materials in many areas of construction.

Common applications are in earthworks, on landfill sites, in road and railroad construction, dam and patio construction, and as protective materials for plastic sealing sheets.

ofi’s experts look into specific questions regarding the suitable choice, dimensioning and testing of sealing sheets and geosynthetics.

As ofi’s customers, producers and downstream users of sealing sheets and geosynthetics benefit from superior product testing and quality assurance services.
