How We Develop
Material Logic, Toolbox Principle and Validation
The starting point of every BPS development is a defined physical target behaviour — not a raw material. From three defined raw material classes, targeted combinations and layer logic produce formulations that meet specific performance objectives under real operating conditions.
Raw Material Basis
Three Raw Material Classes — the Foundation of All BPS Formulations
All BPS systems are built from the same raw material basis. The three classes are individually documented in established industrial applications — BPS links them through defined formulations and layer logics to create new physical modes of action that none of the classes can generate alone.
Film-forming, structure-building and rheologically active macromolecules of natural origin. Primary binding component in all BPS systems — responsible for adhesion, film integrity, degradation behaviour and substrate interaction.
Polysaccharides (CMC, chitosan, guar, xanthan, starch derivatives) · Lignin derivatives · Cellulose fibres
Mineral structural components with defined layer charge, swelling capacity and reactivity. Control barrier properties, swelling pressure, ion exchange and mechanical framework formation within the layer.
Bentonite · Metakaolin · Phyllosilicates · Perlite · Expanded glass · Pozzolans
Mechanical framework and process control. Fibres increase crack tolerance, tensile strength and erosion resistance of the cured layer. Additives control rheology, application stability, degradation rate and weathering resistance.
Basalt fibres · Natural fibres · Cellulose · Hydrophobising agents · Defoamers · UV stabilisers
Secondary Raw Materials as System Components
In cooperation with partners from the recycling industry, BPS develops the use of verified secondary raw material streams as functional components within these three classes. A prerequisite in each case is independent material testing for contaminant relevance as well as technical characterisation of application-relevant parameters.
Toolbox Principle
Not a Standard Product — but Engineering Competence
The toolbox principle is the central development logic of BPS. The three raw material classes are not combined into a single standardised product, but are assembled in different ratios and layer configurations depending on the target physical behaviour, site parameters and application requirements.
This means: it is not the formulation that is standardisable, but the engineering process that leads to the correct formulation. Four parameters determine the system design in every application — soil type and substrate chemistry, exposure and load characteristics, application logistics, and target state and service life.
This approach explains why generic tender specifications without site characterisation fail structurally: the wrong formulation under wrong assumptions produces no usable result, regardless of how correctly it is applied.
From three raw material classes, site-specific systems emerge through the engineering process
Raw Material Classes by Application Field
The following overview shows which raw material classes are used primarily, supplementarily or not at all in the individual application fields. The combination — not the individual class — generates the system performance.
Formulation & Layer Logic
Each Formulation is Developed for a Defined Performance Window
Layer thickness, porosity, adhesion, degradation rate and substrate interaction are not secondary properties — they are deliberate development parameters. Multi-layer systems follow a defined logic in which each layer fulfils a specific function.
Weather Protection & Service Life Control
Protects the underlying functional layer from UV degradation, mechanical erosion and hydrological stress. Simultaneously controls the degradation rate of the overall system through targeted porosity and degree of hydrophobisation.
Hydrophobisation
Weathering resistance
Primary Performance
Carries the actual physical target behaviour: thermal insulation, barrier effect, moisture conservation, particle stabilisation or fire retardation — realised in each application by a specific raw material combination.
Layer thickness defined
Performance window controlled
Adhesion & Substrate Bonding
Ensures the mechanical and chemical connection between substrate and functional layer. The base layer formulation is substrate-specific — subsoil, snow, organic material and gravel substrates each require different adhesion mechanisms.
Penetration depth
Adhesion strength
Application as an Integral Part of the Formulation
Application method and formulation are developed together — not separately. Nozzle geometry, pump pressure, suspension stability, mixing time and pot life are formulation-side parameters, not execution details. All BPS systems are designed for standard hydroseeders and polymer spray units without specialist hardware.
Validation Methodology
From Laboratory Characterisation to System Readiness
BPS follows a four-stage validation process that ensures formulations not only function in the laboratory but can be reproducibly applied under real operating conditions by external service providers.

Operational Competence Anchoring
Laboratory Development Coupled with Field Operations
Formulation development that does not learn from field operations optimises past practice. BPS is structurally linked to SR Begrünungstechnik GmbH (Germany) — a company with long-standing operational experience in the application of hydroseeder and polymer spray systems on erosion control and restoration sites.
This connection is not a reference — it is a structural development channel: substrate knowledge from real projects, application experience with specific machine types and feedback from field operations feed directly into formulation development.
Application Technology
Operational experience with standard hydroseeders (jet and agitator types) and polymer spray units for high-viscosity, fibre- and solid-laden suspensions. Mixing times, nozzle geometries and pump curves are factored into formulation development.
Substrate Knowledge
Direct access to real-world substrates — subsoil, embankment material, landfill covers, snow depots — as a test basis for laboratory formulations. No synthetic model substrate as a proxy for real conditions.
Field Feedback
Deviations between laboratory predictions and field results are systematically recorded and fed back as correction parameters into formulation development. This cycle is the central quality assurance element.
Partner Integration
For application fields outside the core competence area — geo-engineering, contaminated site remediation, recycling technology — BPS works with specialised partners whose field competence is structurally integrated into the respective system development.
Technical questions on the development logic or the toolbox principle?
BPS works with system partners, licensees and industrial clients. If you have a specific requirement, we will jointly assess which system combination is appropriate — or whether contract development is the more suitable route.
