Application Field
Soil Protection & Erosion Control
Erosion begins with the detachment of a single particle from the soil matrix. BPS develops mineral and fibre systems that create structural interlocking where it is absent — as the prerequisite for slope stability, water retention and vegetation establishment.
Physical Basis
How Erosion Occurs — and Why Interlocking is the Critical Variable
Every erosion process begins with the same mechanism: a single particle detaches from the soil matrix. Unstable soils lack the structural interlocking that prevents this detachment. The consequences are twofold — and both have long-term implications.
First, mechanical instability: surface particles are removed by wind, dislodged from the matrix by raindrop impact, or slide under self-weight and pore water pressure. Second, functional loss: soils without interlocking cannot retain adequate water or nutrients. They remain bare subsoil — vegetation establishment is not possible without prior structural development.
BPS systems address this root cause. Through the targeted introduction of mineral components and fibre materials, structural interlocking is created within the soil — not as surface sealing, but as a mechanical framework within the soil matrix.

Working Principle
Structural Interlocking — the Basis of All BPS Soil Systems
Loose soil particles provide neither mechanical stability nor functional capacity. The targeted introduction of fibre materials and mineral components creates a three-dimensional framework within the soil matrix — this mechanism underlies all three application scenarios.

Application Scenarios
Three Scenarios — Three Different Performance Logics
Erosion control is not a standardised product. Depending on site, exposure, target condition and time frame, different system combinations are required. These three scenarios illustrate the range — and why the toolbox logic is the only technically sound answer.
Construction Sites & Soil Stockpiles
Temporary stabilisation of open subsoil — with regulatory cover requirements and water protection obligations.
Arid Soils & Desert Fringe Zones
Structural development in soils without retention capacity — as the prerequisite for water retention, nutrient retention and vegetation establishment.
Steep Slopes & Land Reclamation
Temporary stabilisation with simultaneous germination substrate — transfer of long-term stabilisation to the target vegetation.
Scenario 01
Construction Sites & Soil Stockpiles — Organic Cover Instead of Plastic Film
Infrastructure construction generates large volumes of excavated material stored in stockpiles. Soil protection legislation in the EU and many national frameworks requires erosion control measures for stockpile storage periods exceeding two months — currently implemented predominantly through plastic film covers. Films must be fully removed prior to backfilling, are classified as special waste and generate substantial disposal costs.
BPS is developing an organic cover system based on cellulose and fibre materials, applied by spray. The decisive difference: no removal is required. During backfilling, it integrates into the soil matrix — without introduction of foreign material, without disposal effort.
Soil Classification Maintained
| Criterion | Plastic Film | BPS Organic System |
|---|---|---|
| Removal | Fully required before backfill | Not required |
| Disposal | Special waste — cost-intensive | No waste — biodegradable |
| Soil classification | Not affected | Maintained — calculated and verified |
| Erosion protection | Mechanical (surface cover) | Structural (interlocking + cover) |
| Application | Manual — lay flat across surface | Spray application — fast, scalable |
Scenario 02
Arid Soils & Desert Fringe Zones — Interlocking as the Prerequisite for Life
Desert represents the most extreme case of absent soil structure: no water retention, no nutrient storage, no vegetation establishment possible. Sand erosion, dust control and infrastructure protection — windblown sand on highways and railway lines — are not separate problems but symptoms of the same root cause: absent interlocking.
BPS systems introduce mineral and fibre materials in a targeted manner to create a structural foundation within the soil matrix. The result is a soil with measurable water retention capacity and nutrient retention — the prerequisite for any target vegetation to establish. Nutrient additions are a separate topic, to be addressed independently of the BPS system.
BPS is working with cooperation partners in the context of Saudi Vision 2030 on large-scale greening of desert fringe and desert zones. This project connects all three performance levels — sand erosion, dust control and infrastructure protection — in the logical context of vegetation technology.

Scenario 03
Steep Slopes & Land Reclamation — Temporary Stabilisation with Vegetation Handover
Embankments, dam fills and reclaimed surfaces combine two conflicting requirements: stabilisation must take effect immediately — while simultaneously not impeding germination and root penetration of the target vegetation. Every erosion begins with sediment loss; the BPS system interrupts this cascade in the initial phase.
The performance principle is temporally structured: during the initial phase, the mineral-fibre system stabilises the surface mechanically and creates the germination substrate. As root penetration advances, the target vegetation takes over long-term stabilisation — the BPS system biodegrades once it is no longer required.
This approach requires combined knowledge from soil physics, geomechanics and vegetation technology. BPS works closely with partners in geo-engineering and vegetation technology to provide planners and contractors with site-appropriate system combinations and engineering services.

System Logic
The Toolbox — Why No Single Product Works
All three scenarios share the same fundamental principle — structural interlocking — but require different active components, time frames and handover mechanisms. This makes the toolbox logic the only technically sound response: not a single formulation, but the engineering competence to determine the right combination for each site.
Toolbox logic — three scenarios, three system combinations from the same component base
Four Parameters That Determine Success or Failure
Every effective erosion and water protection measure requires knowledge of four core parameters. Without these, no technically sound system design — and no defensible acceptance — is possible. This is why generic tender specifications fail structurally: it is not the formulation that is standardisable, but the engineering process logic that leads to the right formulation.
Soil Type & Structure
Particle size distribution, pH, nutrient availability, water retention behaviour — determines the formulation logic.
Terrain & Slope Geometry
Gradient, aspect, precipitation load, runoff dynamics — determines the system intensity.
Accessibility & Logistics
Equipment deployment, application method, weather dependency — determines the application procedure.
Target Vegetation & Land Use
Permanence, maintenance requirement, hydrological function — determines the handover mechanism.
