The Multiserwis company was set up in November 1991 in Warsaw under the name Willich Sp. z o.o., as a joint venture company with 100 % of German capital. The company started its activity in Poland, specializing in insulation techniques for power, chemical, oil, cement, food and building industry. A dynamic upturn of domestic economy in '90 enabled a rapid development of the company which quickly has adjusted to the market and required standards. Thanks to perfect organization and reliable realization of all tasks taken, Multiserwis is today the leading forefront in industrial insulation in Poland.

The taking over of Willich Sp. z o.o. by Rheinhold & Mahla AG consortium, the biggest group in Europe that offered services in industrial insulation, was a very significant event before entering in the new millennium.

As a result of the fusion, since 1st January 2000, the company Willich Sp. z o.o. has become the member of Rheinhold & Mahla AG concern. The merger enabled us to extend our offer and use new technologies. The direct result of the change was the change of the company's name from Willich Sp. z o.o. that was valid until 14th November 2002, to R&M Industrial Services Polska Sp. z o.o.

In 2006, the Rheinhold & Mahla AG concern, which main shareholder is Bilfinger Berger SE has changed the name to Bilfinger Industrial Services GmbH.

On 25th September 2012 Bilfinger Berger became the BILFINGER.

Following the change of the name of our main shareholder, on 30th November 2012 the name of our company was adjusted to the existing rules in the group. There are no more word BIS, or rather the abbreviation of the group in Munich. Our new name is:

  • Multiserwis - that indicates wide range of services we provide


At the moment Multiserwis Sp. z o.o. employs approximately 3500 workers on building sites in the country and abroad. We have well qualified engineering - technical staff as well as specialists in organization, supervising and construction management, therefore we are able to successfully realize many tasks. The company possesses over 95.744.379 PLN of capital including the stock in the amount of 3.000.000 PLN. In 2017, our company reached 708 million PLN turnover.

From the year 2012 we possess 100% of stocks in the BIS Plettac Company in Ostrzeszów.
