KUMU under-ground depositary ceiling

Kumu is the main building of the Art Museum of Estonia, located in Tallinn, Kadriorg (Weizenbergi 34/Valge 1). Kumu houses two main collections of the Estonian art: classical collection from 18 century last decades until the end of the World War II and the Estonian art from the Soviet period of the years of 1945–1991.

A winner of the international architectural contest was Finnish architect Pekka Vapaavuori. On 13 May 1994 a design contract was signed between the Art Museum and the architect. By 1999 a project concept was made not including the use of the national budget. The project was put forward by Pekka Vapaavuori, Engel OY, engineering firm Estkonsult from Estonia and Finnish engineering firm Olaf Granlund OY Soomest in cooperation with the Art Museum personnel. The building construction was started in 2002. Kumu Art museum opened on February 18, 2006. The construction area is 6430 m² and the land area is 36 206 m².


What we did

We performed waterproofing works on upturned roof of KUMU building depositary of the Art Museum of Estonia using GRACE Bituthene systems.

What we used

The angles were rounded with liquid membrane GRACE Bituthene LM. The roof ceiling was primed with Primer B2 overcoated with laminated membrane GRACE Bituthene 4000. The overcoat – laminated membrane GRACE Bituthene 8000. The laminated membrane edges were sealed with liquid membrane GRACE Bituthene Mastics, joints and areas around the sole plates anchors were sealed with liquid membrane Bituthene LM. For heat protection we installed Styrofoam and overcoated it with geotextile drainage and protection mat Plasto-Drain (ISO-DRAIN 8 Geo).
