Restoring website after hack

This website and our other website Ple4Win have been hacked recently. Our apologies for that.

We are in the process of restoring both websites. While this is happening, some parts of the website such as the forum can be offline. Please be patient, we will restore functionality as soon as possible.

As the websites are hosted separately and no personal information is asked or stored (even the e-mail addresses for download are not retained) there has been no data breach, no personal identification information could have been obtained by the hackers.

r+k dag 2018

Op dinsdag 13 februari 2018 heeft in het Veur theater in Leidschendam de r+k dag 2018 plaats gevonden. Het was een goed bezochte, interessante meeting waarbij naast het elkaar zien en spreken twee belangrijke gebeurtenissen plaatsvonden:

  • de aankondiging dat sinds eind 2017 Marco Lammers de nieuwe directeur is van r+k,
  • een lezing van auteur en journalist Frank Westerman over zijn recente boek In het land van de ja-knikkers.

Hieronder een foto-impressie van de dag.

For our English readers:

We held a meeting for customers and relations of our company on February 13, 2018, at the Veur theatre in Leidschendam. It was an interesting meeting with lots of good conversations. Two events stood out that day:

  • the announcement that since the end of 2017 Marco Lammers is the new director of r+k,
  • a lecture by author and journalist Frank Westerman about his recent book “In het land van de ja-knikkers” (In the land of the Yea-sayer’s).

Below a couple of pictures taken that day.

50 years Ple4Win anniversary

On October 1, 2015, we celebrated the 50th anniversary of Ple4Win, more specifically that 50 years ago the necessity arose to calculate the behaviour of buried pipelines in soft soils. Since then, we have been analysing the behaviour of pipelines, modelling the pipe-soil interaction and developing specialised computer programs to do those calculations.


For more information about the anniversary, see the Ple4Win website.
