The Naue Portal combines the SolutionFinder with specialised calculators for geotechnical design tasks. Design engineers, engineering consultancies and contractors can define applications systematically, process project-specific inputs and – depending on the selected module – generate layer configurations, design checks, quantities, product recommendations and documented calculation results.
In brief: The Naue Portal is Naue's browser-based platform for geotechnical solution selection, design and project documentation. It includes the SolutionFinder and the DesignSuite with application-specific calculators.

The available modules cover a range of design tasks in road and earthworks engineering, working platforms, erosion control, hydraulic engineering, and lining and retention systems. Select the tool that matches your project’s application area and profit from:
Geotechnical projects do not always begin with a predetermined product or a specific design method. The Naue Portal therefore provides two routes into the design process: start with the engineering application in the SolutionFinder or go directly to a specialised calculator in the DesignSuite. Select the section that matches your project question and open the relevant detail page for information on inputs, design method, outputs and application limits.
The right place to start when the engineering application is known, but the product, system configuration or design route has not yet been defined.
The direct route when a specific design or comparison task needs to be completed.
Each calculator is developed for a clearly defined design task. The Naue Portal therefore does not apply one generic formula to every application. Instead, each module identifies the underlying method, the required inputs and the calculated outputs. This allows users to establish early whether the tool is suitable for the project task and the applicable standards and guidance.
The method to be applied to a particular project depends, among other factors, on the project location, contractual basis, national requirements and actual site conditions. Each tool page must therefore state the method, scope, inputs and outputs clearly.
| Method/basis | Typical application in the Portal | What the relevant module assesses |
|---|---|---|
| Flexible pavements |
| Required structural pavement composition; depending on the tool variant, comparison of an unreinforced and geogrid-stabilised aggregate base or assessment of design life. |
| Modified Giroud & Han method (2004) | Unpaved roads, temporary access roads and trafficked areas | Required unbound base-course thickness based on the subgrade, traffic loading and permissible rut depth. |
| BR 470 | Working platforms for tracked plant | Ultimate limit state checks and, depending on the selected verification, serviceability limit state checks, including punching, bearing failure, settlement and inclination. |
| CBR- and EV2-based approaches | Unbound base courses and bearing-capacity targets | Required base-course thicknesses, material quantities and cost comparisons in modules designed for this purpose. |
| DIN 1054 / DGGT-based checks | Layered lining and retention systems on slopes | Slope-parallel sliding stability; where required, design of geogrid reinforcement and anchorage. |
| Bouyze & Schram (1990); Recio & Oumeraci (2007); Hinz & Oumeraci (2002) | Geotextile sand containers in coastal and hydraulic engineering | Container sizing and quantity estimation under wave, current or combined hydraulic loading. |
| EU, LCPC or AASHTO load equivalency | Conversion of actual traffic loads | Equivalent axle load passes as an input for subsequent road and base-course design. |

The quality of a digital calculation result cannot be demonstrated by a general company certification alone. What matters is that users can understand how the result has been derived, which inputs were used and the application range for which the calculation is intended.
The calculators support technical design within the application range described for each module. The reliability of the results depends on the completeness and accuracy of the inputs, the suitability of the selected method and the project-specific conditions. Calculation reports document the basis processed by the tool, but do not replace any required project-specific checks, approvals or professional responsibilities. Use of the Portal and its results is subject to the current terms of use.

Digital calculators cover defined standard cases and input ranges. Where ground conditions, load cases, geometry or project-specific requirements fall outside these ranges, an individual engineering review may be required. The project data and calculation results already available in the Naue Portal can be used as the basis for further consultation with the Naue Engineering and Design Department.
The Naue Portal is a browser-based platform for geotechnical solution selection, design and project documentation. It combines the guided SolutionFinder with specialised calculators in the DesignSuite.
The SolutionFinder starts with the engineering application or geotechnical function and guides users step by step towards a suitable solution or product recommendation. The DesignSuite provides direct access to specialised calculators for design tasks that have already been defined.
The published modules cover, among other areas, road and earthworks engineering, working platforms, erosion control, hydraulic and coastal engineering, and lining and retention systems.
The method depends on the individual calculator. Stated design bases include AASHTO 1993, the modified Giroud & Han method, BR 470, CBR- and EV2-based approaches, DIN 1054/DGGT and design models for geotextile sand containers.
No. Each calculator has a defined application range and requires project-specific inputs. The suitability of a method for a particular project must be assessed against the location, applicable standards and guidance, contractual basis and actual conditions.
This depends on the tool. Typical inputs include geometry, loads, traffic loading, ground parameters, layer properties, material properties or hydraulic actions.
Depending on the module, outputs may include required layer thicknesses, design checks, product or system recommendations, quantities, option comparisons, drawings and a documented report. The relevant tool page describes the specific outputs.
Yes, where product selection forms part of the selected module. In this case, actual Naue product names and type designations are provided so that the recommendation can be identified clearly.
Yes. Calculations can be saved by project; the available report and download functions depend on the individual tool.
Use the enquiry form to contact the Naue Engineering and Design Department. Existing inputs and calculation results can provide the basis for a project-specific engineering review.
Use of the Naue Portal is currently free of charge. A personal user account is required for access. Please visit the log-in page for log-in or registration.
The Naue Portal runs in a web browser and does not require a local installation or separate desktop software. It is intended for use on desktop computers, tablets and smartphones. A larger screen is generally more convenient for completing extensive calculations.
No. The Portal supports defined planning and design tasks, but does not replace any required project-specific review, approval or authorisation. The current terms of use apply.
