Retrival is a company whose main focus, within their demolition activities, is "pre-demolition": removing interior fittings until only the skeleton of the building remains. They provide a service, rather than offering a range of reusable products. The company dismantles complete interiors, and then sorts the waste. The reusable materials are put on the market while they are still at the demolition site, to be picked up by the buyers themselves. Then, whatever isn’t taken directly from the site is transported back to their facilities and sorted, either to be put up for sale on their website cornermat.be, or sent to recycling centers.

Their offer of reclaimed products is therefore extremely varied and potentially includes all of the items that can be removed from a building. In their stock, some items are available on a quasi-permanent basis. For example, Retrival transforms IBC containers into storage tanks. They also have the equipment they need to prepare disassembled frames for resale.

Retrival has two physical sites: an office attached to a warehouse where they sort materials coming in, and a larger warehouse a few kilometers away where they store the majority of their stock. Neither of these places is meant for the viewing of materials that are for sale; that takes places primarily through their online store.
