You call upon Deschacht, its engineering department, its Ribwall PP pipes, and custom inspection chambers. That was the smart choice made by contractor Jazy for a project in Evere.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">General contractor Jazy, a company that also engages in real estate development, is currently constructing 71 residential units on the corner of Eenboomstraat and Henry Dunantlaan, featuring parking facilities across two basement levels. The project lacks any outdoor space for water drainage. To allow it to infiltrate nonetheless without discharging it into the existing sewage system, a basin with a dispersion drainage system was chosen beneath the foundation slab of level -2.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Plastic instead of concrete<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis was a totally new case for us, because of the nature of the soil,\u201d says Eric Debruyne, who is responsible for purchasing at Jazy. \u201cThat is why we carried out soil tests and analyses to find out if there would be sufficient infiltration. Ultimately, we chose a basin, while retaining the draining sand layer.\u201d.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cFirst we thought of concrete inspection chambers and pipes,\u201d Eric Debruyne continues. \u201cBut we received an interesting proposal from Deschacht, one of our regular partners, to use polypropylene infiltration pipes instead, and polyethylene inspection chambers suitable for drainage pipes.\u201d<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Special tubes<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cIn close collaboration with the contractor, our engineering department drew up the layout and installation plans for the basin elements,\u201d says Dimitri Steilen, project manager at Deschacht. \u201cThe inspection chambers were custom-made by Collinet. The 50 meters of pipes are made of perforated PP Ribwall with a diameter of 1000 mm. A geotextile jacket protects the basin, which is also lined with Argex, against the intrusion of surrounding soil. The PP Ribwall pipes are characterized by their double wall: an outer wall with ribs that provide an even larger infiltration surface and a smooth inner wall with the desired perforations. A product and a system with nothing but advantages: exceptionally short manufacturing times, a lighter weight for handling, and, on-site, faster execution of the work. Those are features that every contractor is happy with \u2026\u201d<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-1 is-layout-flex wp-block-gallery-is-layout-flex\">\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"26001\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-realisatie-jazy-evere-3.jpg\" alt=\"Deschacht realization Jazy Evere 3\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"26003\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-realisatie-jazy-evere-4.jpg\" alt=\"Deschacht realization Jazy Evere 4\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"26005\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-realisatie-jazy-evere-1.jpg\" alt=\"Deschacht realization Jazy Evere 1\"\/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" data-id=\"26007\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-realisatie-jazy-evere-2.jpg\" alt=\"Deschacht Realisation Jazy Evere 2\"\/><\/figure>\n\n<\/figure>\n\n\n\n<h4 class=\"wp-block-heading\">Language<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Location: Schaerbeek Founded: 1978 Staff: about ten people Activities: General contractor \u2013 Promotion and construction of residential buildings Services for this project: Promotion and construction of a building with 71 apartments<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/www.deschacht.eu\/wp-content\/uploads\/2026\/05\/deschacht-realisatie-jazy-evere-2.jpg\" alt=\"Deschacht Realisation Jazy Evere 2\"\/><\/figure>","protected":false},"featured_media":2416,"template":"","meta":{"_acf_changed":false},"activiteiten":[172,177,174],"producten":[137,136,138],"class_list":["post-2412","realisaties","type-realisaties","status-publish","has-post-thumbnail","hentry","activiteiten-algemene-aanneming","activiteiten-engineering","activiteiten-weg-en-rioolwerken","producten-infiltratiebuizen","producten-infiltratiekratten","producten-toezichtputten"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.5 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Weinig ruimte?
