About Relok

What is Relok
Relok is a Software application for procurement and resource management in the construction industry. The platform links the products and services of recycling and disposal companies, gravel and asphalt plants, and other bulk material suppliers. Relok combines the search queries with the suppliers' product data and filters out exactly those that are optimally matched to the searcher's requirements. Suppliers and searchers can thus network and collaborate in real time. Construction companies in their role as operators of construction sites or tipping points can also offer and supply products. Furthermore, Relok supports the management of material resources within companies. Together, Relok can be used in estimating, purchasing, sales and on the construction site.
