Saving Cost Through Innovation

 

The goal of our developers was to create an long-term solution for high-quality ground stabilisation with a measurably lower input of resources like time, money and materials. This goal was reached with the development of Underbold®. This is noticeable in the reduction of construction time, minimised effort and savings in material, personnel and machine costs – compared to conventional construction methods.

 

„Lost time is never recovered“

 

In every construction project time is an essential factor. With our products of the Underbold® group we attain significant time savings for our clients. Our wax emulsions are quickly applied and bond the treated cubical within a few hours. The treated area is completely loadable within a few days.  

 

Economic Advantages

  • Cost reduction through - up to 5 times - faster construction time for the foundation
  • Elimination of layers without bonding agent
  • Reduction of cement amounts for the requirements to load baring capacities
  • Extended durability of the foundation - permanently no restoration works necessary
  • Savings through reduction or prevention of excavated ground materials
  • Elimination of disposal costs

Technical Advantages

  • Increase in load bearing capabilities
  • Increase of stiffness modulus
  • No setting of grooves or relaxing necessary
  • Reduction of the setting period outside the application period
  • Reduction of micro pores and capillary effect
  • Reduction of shrinking tendency and thus practically free of crack formation
  • Completely frost-resistant

Advantages for Our Environment

  • Saves resources for the production of raw materials and the disposal of dangerous goods
  • Reduction or elimination of excavation materials
  • Reduction of CO2 emission through minimal transport needs for excavation materials and filling materials
  • Durability prevents early restoration works

Construction With Underbold®

 

For the application of Underbold® products only conventional construction machines are needed. We accompany our clients worldwide and communicate the know-how for the correct application of the biological wax emulsions.

 

Preparation:

 

Soil examples are taken in order to determine the weight, humidity and composition of the soil. Based on this data the right wax emulsion is identified and the exact Underbold® mixture ration and proportions are set.

Only with soils covered by organic growth the top layer is stripped of about 5-15 cm in order to eliminate all organic materials like e.g. roots or similar. If roads are modernised or new roads built on dirt roads, no preparation is necessary.

 

Step 1/5: Mixing-In

The wax emulsion is evenly mixed into the natural soil with the help of a milling machine. Through this professional treatment an even, homogenous mixture of Roadanic® and the natural substances of the soil is created.

Step 2/5: Pre-Compacting

Via a roller compactor the loosened soil is brought back to its original level an slightly pre-compacted so the subsequent construction machine do not sink in and an even treatment in the necessary depth can take place.

Step 3/5: Spreading of the Bonding Agent

The bonding agent (e.g. common Portland cement or lime) is distributed in the right proportions via spreading vehicles.

Step 4/5: Mixing-In of the Bonding Layer

The bonding agent is evenly mixed into the soil via a milling machine.

Step 5/5: Final Compaction

Now all the necessary components for the stabilisation of the ground have been worked into the soil. With a roller compactor the surface is now compacted so an optimal compaction is reached and our Roadanic® products can perfectly take effect.
