The context: directional drilling, tunnel boring machines and management of excavated materials
On directional drilling and tunnel boring machine sites, managing excavated materials is a major challenge. Soil mixed with drilling fluids generates liquid sludge that must be stabilised before disposal. Its consistency makes transport complex, increases logistics costs and can lead to spillage risks. To maintain site performance, rapid and safe sludge dewatering is essential.
Traditional solutions: effective but restrictive
Historically, several methods have been used for sludge dewatering, but all have significant limitations.
Lime, which is commonly used, remains dangerous for operators due to its exothermic reaction, which can cause burns and uncontrolled heat release. Powdered cementitious binders require a long reaction time and their effectiveness varies depending on the nature of the soil, which significantly slows down the work. Filter presses are effective, but the equipment is bulky, energy-intensive and difficult to deploy on mobile sites. Although these alternatives are well known, they do not fully meet current requirements for simplicity, safety and responsiveness.
The ideal alternative: APROMUD® super drying agent
For fast and optimised sludge conditioning, APROMUD® offers an innovative solution based on superabsorbent polymers. It is incredibly easy to use: simply spread the product, mix and wait 15 minutes to obtain solidified sludge that is ready for disposal. APROMUD® is safe for operators, requires a dosage of less than 1%, offers immediate effectiveness, and optimises skip loading while ensuring safe transport. A solution designed for the modern challenges of construction sites and the need for speed.
An environmentally friendly, low-carbon product
APROMUD® is fully in line with the circular economy approach. Made exclusively from recycled materials, it is a low-carbon product that is environmentally friendly and poses no risk to human health. It is inert on mineral sludge and 100% biodegradable on organic sludge in accordance with standard NF EN 14995. A responsible choice for reducing the environmental impact of construction sites while improving their efficiency.
Simple and operational application process
One list to remember to understand ease of use:
• Spread the product
• Mix and wait 15 minutes
• Remove solidified mud
How about we schedule a trial run?
Are you sceptical when watching the demonstration videos? That’s normal. Many people think the results are ‘too good to be true’… until they try it out for themselves. At every demonstration, the reaction is the same: teams are amazed by how fast it works and how easy it is to use. A demo is worth a thousand words, and we are confident that you will be completely satisfied when you test APROMUD® on your own sludge.
