Construction and infrastructure projects generate thousands of tons of wet sludge every year. Whether produced by tunnel boring machines (TBMs), diaphragm walls, drilling operations, concrete plants or environmental remediation projects, these materials are often difficult and expensive to transport in their original state.
APROMUD® is an innovative super drying agent designed to transform liquid and semi-liquid sludge into stable, transportable material within minutes. Thanks to its unique superabsorbent polymer technology, contractors can improve site productivity, reduce logistics costs and support more sustainable waste management.
Why wet sludge is a major challenge on construction sites
Managing construction sludge has become increasingly complex due to stricter environmental regulations, rising disposal costs and limited treatment options.
High moisture content significantly increases transportation costs while making excavation spoil difficult to handle safely. Wet materials can stick to truck bodies, leak during transport and complicate disposal or reuse.
As infrastructure projects continue to grow in scale, contractors are looking for faster, safer and more economical sludge treatment solutions.
Traditional sludge treatment methods have their limits
Several techniques are commonly used to improve sludge consistency before transport.
Lime and cement are frequently added to reduce moisture, but they generally require high dosages, increase the final waste volume and may generate exothermic reactions that complicate handling.
Mechanical dewatering systems can be effective but often require costly equipment, dedicated operators and additional installation space.
These methods can increase project costs while slowing daily operations.
A different approach: superabsorbent polymer technology
APROMUD® works differently.
Instead of chemically stabilizing sludge with mineral binders, it rapidly captures and locks water molecules inside a highly absorbent polymer structure.
Within approximately 10 to 15 minutes, liquid or sticky sludge becomes a stable, manageable material that can be excavated, loaded and transported with conventional equipment.
The treatment process is simple, fast and easy to integrate directly into daily construction operations.
Why contractors choose APROMUD®
Construction professionals choose APROMUD® because it combines operational efficiency with environmental performance.
Its main advantages include:
- Very low dosage rates, often below 1% of treated volume
- Rapid treatment in just 10 to 15 minutes
- Neutral pH
- No exothermic reaction
- Non-corrosive and easy to handle
- Reduced transport costs through improved material consistency
- Lower fuel consumption by reducing unnecessary truck movements
- Improved site cleanliness and safety
- Easy implementation without heavy equipment
These benefits help contractors improve productivity while reducing operational costs.
Applications across multiple industries
APROMUD® is suitable for a wide range of industrial and construction applications where wet materials create handling or transportation challenges.
Tunnel boring machine (TBM) slurry
Large tunnelling projects generate considerable volumes of excavated slurry every day.
APROMUD® quickly transforms fluid spoil into stable material that can be loaded more efficiently, reducing delays and improving logistics.
Diaphragm walls and foundation works
Foundation projects involving diaphragm walls, bored piles or barrettes often produce bentonite or polymer-based drilling slurry.
After treatment with APROMUD®, these materials become easier to excavate, transport and manage on site.
Horizontal directional drilling (HDD)
Drilling mud generated during HDD operations often remains highly fluid after excavation.
The rapid drying action of APROMUD® simplifies handling while reducing the risk of spills during transportation.
Concrete plants
Returned concrete wash water and slurry can be difficult to manage because of their high water content.
APROMUD® improves handling while reducing the number of waste transport operations.
Environmental remediation
Contaminated sludge generated during remediation projects often requires stabilization before disposal.
The product helps improve material consistency, making transportation safer and easier.
Mining operations
Mining activities frequently generate wet mineral residues and drilling sludge.
APROMUD® helps optimize spoil handling while simplifying transport logistics.
Reduce transport costs and carbon emissions
One of the main economic advantages of APROMUD® is its ability to improve transport efficiency.
By transforming wet sludge into a stable material, contractors can optimize truck loading conditions, reduce material losses during transport and improve loading operations.
Fewer transport movements also contribute to lower fuel consumption and reduced greenhouse gas emissions, supporting both operational efficiency and environmental objectives.
Supporting sustainable construction
Sustainability has become a key priority throughout the construction industry.
APROMUD® contributes to more responsible sludge management by helping companies improve waste handling while reducing the environmental impact associated with transportation and disposal.
The product is manufactured using raw materials sourced from 100% recycling channels, reflecting APROTEK’s commitment to circular economy principles and sustainable innovation.
A simple process that fits daily operations
One of APROMUD®’s greatest strengths is its simplicity.
The product can be applied directly to freshly excavated sludge using standard construction equipment.
After mixing, the material rapidly changes consistency, allowing operators to continue excavation, loading and transportation without lengthy interruptions.
No complex machinery or dedicated treatment installation is required.

Frequently asked questions
What is a sludge drying agent?
A sludge drying agent is a product designed to reduce the free water contained in wet sludge, making it easier to handle, transport and dispose of.
How quickly does APROMUD® work?
In most construction applications, the sludge reaches a workable consistency within approximately 10 to 15 minutes after mixing.
Which industries use APROMUD®?
APROMUD® is widely used in tunnelling, foundation engineering, horizontal directional drilling, mining, environmental remediation, concrete production and wastewater treatment.
Is APROMUD® safer than traditional lime treatment?
Unlike lime-based treatments, APROMUD® has a neutral pH and does not generate an exothermic reaction during use, making handling simpler for operators.
Can APROMUD® help reduce transportation costs?
Yes. By improving sludge consistency, contractors can simplify loading operations, reduce material losses during transport and optimize overall logistics.
