VT4 is one of the most important routes for heavy traffic in Finland.
The objective of the Finnish Road Authority is the reduction of traffic victims and accidents with personal injury. The project inaugurated at the end of 2021 aims to significantly improve safety with new junctions, a new parallel route and new pedestrian and bicycle lanes.

GEO PP 5NG / 08 was installed to perform the filtration and separation functions.

Non-woven geotextiles installed in road constructions are sustainable solutions because:

• They preserve natural resources such as sand and gravel
• They are quick and easy to install, saving time and money and reducing project costs
• Compared to traditional methods, they require less use of vehicles for the transport and handling, with a consequent reduction in costs and CO2 emissions
• Their high durability increases the useful life of the infrastructure and reduces maintenance costs.
