With the Quadro-Secura® Quick by DOYMA redevelopments and new installations of pipes, tubes and wires in existing buildings are done in a simple and secure way. The fitting can be carried out at every usual wall structure (bricks, drain concrete, aerated concrete bricks, waterproof concrete, element walls, walls with outside sealing, etc.). Available cavities (e.g. with air bricks) do not have to be backfilled, the otherwise necessary use of sleeve pipes can be skipped here. The installation is quick, uncomplicated and does not need any further aid.
