Our history

Our highlights of the past 25 years

Height Specialists was founded in 1995 on the 24th of May. That means that this year we are celebrating our 25th anniversary! The past 25 years consisted of growth, development and experience. Where in 1995 we were still seen as cowboys, abseilers and climbers, we have now grown to become the specialist in working safely at height. To celebrate this anniversary, we will count down together to this special day and share all the highlights of Height Specialists throughout the year.


Stunts at height

From the beginning, Height Specialists has assisted in height stunts of various television programs. Like the program Now or Never, where viewers with certain phobias or fears were challenged to overcome “their fears” in return for large sums of money. Fear of heights is one of the most common fears and therefore many stunts were performed at height.

Abseiling Euromast

Abseiling from the Euromast, who’s not familiar with it? Since 1995 the real daredevils have the opportunity to abseil from the Euromast. An event that started small at the time, but has grown into one of the most famous activities in Rotterdam. But where did the idea come from?

Height Specialists founded

Height Specialists was founded in 1995 by Sander Louwrier. Sander grew up climbing and prefered to do this everyday. That’s when he decided to share his passion of climbing with others. Together with two friends he founded Height Specialists and started in a basement box with two rolls of rope under his bed.

Zip line Euromast

Since 1996 Height Specialists has started to organize not only the abseil but also the zip line of the Euromast. This is the fastest zip line in Europe! Instead of taking the lift down, we make sure that participants can get to the ground safely from a height of 100 meters (with 100 km/h) in about 15 seconds.


Height Specialists Events

In the early years of Height Specialists the focus was mainly on events. Since 1995 we started abseiling and ziplining from the Euromast and since 1997 we also organised many group and team building activities at height. Activities such as climbing walls and height parcourse where safety has always played an important role. Whether it is an event or industrial work, safety has been priority since 1995.


The number of industrial projects is increasing

As of 2000, projects at height in our ‘Industrial’ division increased. The industry discovers that rope access is a safe, efficient and often cost effective working method.

New Sponsor

Height Specialists was in 2000 sponsored by Pepsi for events such as abseiling and zip lining from the Euromast.


Abseiling Arsenal Tower

Height Specialists started working together with the Arsenal tower in Vlissingen in 2001. Due to the great success of the abseiling and zip lining from the Euromast, this 65 meter high watchtower was a nice spot for a second abseil location!

A number of superheroes will abseil from the roof of the Sophia in a spectacular way and appear in front of the children’s windows.
