An HDPE geocomposite nodular drainage protection board with a geotextile fleece is a specialized product used in various civil engineering and construction applications. Let's break down the components and their functions:
High-Density Polyethylene (HDPE): HDPE is a durable and lightweight plastic material known for its high strength and resistance to chemicals and moisture. In the context of a geocomposite nodular drainage protection board, HDPE is used as the base material for the board.
Geocomposite Structure: The geocomposite structure refers to the combination of multiple materials in a composite form. In this case, the geocomposite structure consists of the HDPE base and other layers.
Nodular Design: The drainage protection board typically has a nodular or dome-like design on the top surface. These nodules or domes create void spaces, allowing water to flow freely within the board.
Drainage Function: The main purpose of the geocomposite nodular drainage protection board is to provide effective drainage in various applications. It allows excess water to drain away from the surface, preventing waterlogging and potential damage to underlying structures.
Protection Function: The drainage protection board also acts as a protective layer for the underlying structures. It provides a barrier against root penetration, abrasion, and physical damage that may occur during construction or regular usage.
Geotextile Fleece: The geotextile fleece is a non-woven fabric made from synthetic fibers. It is typically attached to the HDPE base of the drainage protection board. The geotextile fleece serves multiple purposes, including filtration, separation, and reinforcement. It acts as a filter by allowing water to pass through while preventing the ingress of fine particles that could clog the drainage system. It also separates different soil layers and provides additional strength and stability to the overall composite structure.
