We are a PVD producer and ground improvement contractor with a long track record and in-house geotechnical engineering. Our first projects in the field of prefabricated vertical drains originate from the end of the 1970-ties. Before the development of the prefabricated vertical drains, Cofra installed sand piles to accelerate the consolidation process. Cofra started with only the installation of vertical drains but gradually expanded its portfolio with complementing techniques being nowadays able to provide clients a complete portfolio of ground improvement techniques to unlock the potential of all soil types.

Innovation, reliability and professionalism are embedded in our DNA
