What is Boroplast?
Boroplast is the process for the layer-by-layer, machine-compacted backfilling of exploratory boreholes.
In short: Greater safety in the building ground.
Boroplast makes backfilling boreholes in civil engineering safe.
No settling, no water ingress, no sagging of the filling.
Secure building ground even after the exploratory drilling
The subsoil is disturbed by exploratory drilling and its subsequent backfilling. The type of backfill used is more likely to destabilize the subsoil than the drilling itself.
The solution lies in the type of backfilling.
The new Boroplast process brings new safety and stability to the drilled subsoil.
For the first time, it has been possible to fill boreholes layer by layer using compacted material, achieving quality on a mass scale.
Mechanical compaction of cohesive building materials in the borehole.
Procedure
The exploratory borehole will be sunk and cased as usual.
After the probe is removed, the protective pipe is pulled out.
Conventional backfilling is used from the deepest part of the borehole down to -4,500 mm.
From -4,500 mm to ground level, the soil is compacted and mechanically filled in layers.
The sealing material at the target moisture content is poured in layers and compacted using a tamping piston.
This creates a dynamically resilient, dense filling element.
Advantages of the procedure
No setting.
The sealing material is mechanically compacted to such an extent that cavities are compressed so much that subsequent settling is unlikely.
Hydraulically sealed.
The cohesive building material exhibits such high compaction that surface water is prevented from penetrating the subsoil. The system is hydraulically sealed.
Dynamically resilient.
Due to its elastoplastic properties and its floor-adapted stiffness, the Boroplast sealing element can withstand cyclic dynamic loads.
CO2 neutral building material
Environmentally and climate-friendly process. Positive climate balance. No cost risks, for example, due to CO2 pricing.
Moving
- The push chain drives the plugging piston.
- Powerful mechanical compaction with a contact pressure of 4 - 15 kN (controllable)
- powerful, void-free compaction
- Low overall height thanks to push chain technology
- Robust, tried and tested drive technology with 50 years of experience
Reliable, proven, environmentally friendly
In the Boroplast process, exploratory boreholes are filled layer by layer with a specially developed cohesive building material. This layered material is then compressed to its target density in a single stroke using a machine-driven tamping piston.
Reliable quality management. Precise recording of machine data and digital documentation of compaction data. Automated process and more reliable compaction results.
Environmentally friendly, natural, and CO2-neutral building material. Unlike cement-bound slurries, its CO2 balance is positive. The risk of cost increases due to CO2 pricing is eliminated with Boroplast.
