Lifting / renovating

Dool International can combine lifting the roof with an upgrade and renovation of your building, such as installing a new roof, or insulating an existing roof. Any glass or panels used in the building can also be renewed or replaced by products with a higher insulation value. This gives your premises a fresh, new look and increases the effective volume of your building.

How does it work?

Technically proven procedure
Dool International uses a proven, tried and tested procedure to lift industrial buildings. A system of hydraulic props is used to gradually lift the building in a series of compartments. The interconnected props are operated by pressurised air. This ensures a very gradual, smooth process so the stability of the existing structure is safeguarded during the lifting process. Depending on the construction and height of the existing building, we can life the roof to a height of six metres.

Whole process managed centrally
The existing pillars in the building are cut through and replaced by new pillars. As Dool International produces the steel pillars in its own workshop, we can work with every dimension necessary. We are also responsible for all the engineering the project involves. We can also coordinate the entire construction process for you. Our own teams takes care of construction on site, nationally and internationally. After completion, you can always rely on Dool International for after sales service.

100% reliability
A lifted industrial building is also a reliable industrial building. Dool International works in compliance with the requirements imposed on structural buildings by insurance companies.
