Asbestos removal and demolition
Based in Overijse, Demotek is an approved asbestos removal company. For roofs, facades, interiors and pipes, we define the materials to remove, protection measures and waste removal. We also carry out demolition and interior strip-out.

Asbestos roofs
Prepare the removal of asbestos-containing roof sheets or slates before replacing the roof.

Facades & outbuildings
Identify and remove suspect cladding or panels from a facade, garage or outbuilding.

Asbestos & renovation
Clarify suspect interior materials before renovation disturbs them.

Asbestos pipe insulation
Prepare removal of asbestos-containing insulation using an appropriate approved method.

Our approach
Before pricing the work, we identify what must be removed, protected or retained. Your plans and reports help define the work and any checks still needed.
- 01
Describe the project
Give the municipality, parts to remove and parts to retain. Existing plans, photographs and surveys help us understand the building and access.
- 02
Define the work
Distinguish prior checks, work and waste removal. The quote should specify protection, exclusions and coordination with other professionals.
- 03
Prepare the next step
The schedule accounts for formalities and site availability. Agree the expected final condition and completion documents beforehand.
Asbestos removal may precede a roof renovation, strip-out or demolition. From the first discussion, identify the professionals already involved and parts of the building still in use. Agreeing who does what and when helps prepare the handover between trades.

Rules in your region
From Overijse, we discuss projects in Flanders, Brussels and Wallonia. The site’s location determines some of the formalities.
Flanders
In Flanders, distinguish the building’s asbestos certificate from investigation of the actual work area and preparation of removal. For a jointly owned building built before 2001, also check the common-parts file with the building manager.
Read the guide: Asbestos in Flanders
Check the environmental/planning permit or exemption with the municipality. Certain projects require a demolition follow-up plan. Sort material streams and plan hazardous-substance removal before the affected demolition stage.
Brussels
In Brussels-Capital, prepare a file for the whole worksite: materials, quantities, method, access and waste removal. The environmental classification of asbestos work must be checked separately from any planning formalities.
Read the guide: Asbestos in Brussels-Capital
For demolition and alterations, pay particular attention to inventories, prior removal of hazardous materials and waste separation. Also have the planning conditions specific to your building confirmed.
Wallonia
In Wallonia, have the environmental procedure assessed against the materials and the complete project. Prepare the contractor’s survey information and waste route in parallel. Flemish asbestos-certificate rules do not automatically apply here.
Read the guide: Asbestos in Wallonia
Have the municipality confirm planning permission or exemption. If the project also requires an environmental permit, a combined permit application is necessary. Prepare a description of work and affected materials to clarify formalities before setting a start date.
Precise obligations are reviewed for each assignment with the competent authority.
