Dräneringsskikt

Dräneringsskikt, or drainage layer, is a term used in construction and landscaping to describe a layer of material designed to facilitate the removal of water. Its primary function is to prevent waterlogging by allowing excess moisture to drain away from sensitive areas such as building foundations, planting beds, or sports fields.

Common materials used for dräneringsskikt include gravel, crushed stone, or coarse sand. The size and type of aggregate are chosen based on the specific application and the desired permeability. A well-designed dräneringsskikt is permeable enough to allow water to pass through quickly but also prevents finer soil particles from washing into and clogging the drainage system.

In building construction, a dräneringsskikt is often placed around foundations to protect them from hydrostatic pressure and frost heave. It can also be incorporated into green roofs and living walls to ensure proper water management and prevent root rot. In landscaping, it is crucial for improving soil drainage in areas with heavy clay or poor natural drainage, promoting healthier plant growth and reducing the risk of disease. The thickness and composition of the dräneringsskikt are determined by factors such as rainfall, soil type, and the specific needs of the project.
