Basislagen

Basislagen is a Dutch term meaning base layers or foundation layers. It describes the lowest or most fundamental layers in a layered system, providing an interface to what lies beneath and supplying stability or common services to the layers above. The concept is used across multiple disciplines, with each field adopting its own specific interpretation while sharing the core idea of a foundational layer.

In geology and soil science, the basislaag refers to the lowest significant sedimentary layer in a sequence, often used as a reference horizon for dating and correlation, and it can influence properties such as porosity and groundwater movement.

In software and information architecture, the basislaag denotes the lowest layer in a layered architecture, delivering shared services such as data access, persistence, and infrastructure, while remaining independent of higher-level business logic and user interfaces.

In coating and materials engineering, the basislaag can refer to the primer or adhesive layer at the substrate interface, affecting adhesion, corrosion resistance, and the durability of the finished product.
