Chappelle D’Enhaive
Belgium I Jambes

Background

Chappelle D’Enhaive, a new residential complex in Jambes, Belgium, was designed and built with a sustainable mindset right from the start. The complex, comprising of 6 houses and 95 apartments distributed over five buildings, is located near the river of Meuse and has direct access to the centre of the city.

Requirements

The key challenge during the project was to find a solution for fixing the polypropylene pipes that facilitate the hot and cold water supply. Due to the often-changing temperature inside the pipes, they expand and shrink regularly. Therefore, one of the key requirements was to prevent the moving pipes from putting additional force on the fixing system. Next to this, keeping the noise level to the minimum was also an important criterion.

Solution

Walraven technical engineers advised applying Bifix® G2 5000 clamps, designed explicitly for plastic pipes. Thanks to the rubber lining and removable spacer washers, these clamps are suitable for both sliding and anchoring. For mounting the steel pipes, Bifix® G2 clamps with black rubber lining were selected. To distribute the changing length, which is the result of the frequent temperature difference, our engineers drew a solution with two 90 degree bends and split the number of pipes into 2 separate groups so that they would fit through the openings in the wall. Next to high quality and compliant product systems, Walraven supported with technical advice, calculation and design preparation throughout the project.
