This summer, AFTES launched its new online platform designed to promote the know-how of its members and to facilitate access to solutions for underground construction projects. APROTEK is naturally featured with its APROMUD® solution, dedicated to sludge management, sludge treatment and excavated material conditioning on complex construction sites.
AFTES, a key player in underground construction
AFTES (French Tunnelling and Underground Space Association) has been bringing together professionals involved in the design, construction and operation of underground structures for more than 50 years. It plays a major role in knowledge sharing, technical innovation and the dissemination of best practices related to tunnels, underground works and the management of excavated materials.
The challenges of managing liquid excavated materials
On underground construction sites, the management of excavated materials represents a major challenge, especially when spoil is in the form of liquid sludge. Such sludge complicates excavated material conditioning, creates significant logistical constraints and raises safety, transport and regulatory issues. Fast and controlled dewatering is therefore essential to optimize operations and secure material handling.
A look back at our presentation at the AFTES Technical Days
During the AFTES National Technical Days in Toulouse, APROTEK delivered a 20-minute presentation dedicated to excavated material management and sludge dewatering solutions. This session provided an opportunity to share our field experience, engage in technical discussions with industry professionals and address practical issues related to sludge treatment on underground construction sites.
APROMUD®: a high-performance solution for sludge treatment
APROMUD® super-dewatering agent is an innovative solution designed for sludge treatment and excavated material conditioning. It stands out for its very low dosage, operator safety and immediate effectiveness. Non-pulverulent, APROMUD® ensures instant dewatering of sludge, making it easier to handle and transport while improving working conditions on site.
Super-absorbents at the core of the technology
APROMUD® is based on organic super-absorbent polymers capable of rapidly capturing the water contained in liquid sludge. These super-absorbents instantly transform sludge into manageable materials, providing a reliable and proven response to sludge management challenges on construction sites.
A low-carbon and responsible solution
By optimizing loading volumes and securing transport without leakage, APROMUD® helps reduce the number of trucks required and therefore the carbon footprint of construction projects. Its raw materials come 100% from recycling streams, and the solution is labeled Solar Impulse Efficient Solution. This approach combines technical performance, safety and environmental commitment in the management of excavated materials.
Meet APROTEK at the AFTES Congress 2026 in Lille
APROTEK will be exhibiting at the AFTES Congress from October 12 to 14, 2026, in Lille. Come and discover our solutions on our stand, meet our teams and enjoy free demonstrations focused on dewatering, sludge treatment and excavated material conditioning.
