Description

Introduction

Composite drainage board is a building material with drainage, insulation, and anti-seepage functions. Its main uses are as follows:

Drainage function: The composite drainage board has efficient drainage capacity, which can quickly discharge rainwater, groundwater or other sewage, avoid the occurrence of water accumulation, and keep the ground dry.

Insulation function: Composite drainage boards have excellent insulation performance, which can effectively reduce the loss of ground temperature and improve indoor comfort. Meanwhile, in winter, it can prevent ground icing and protect pipelines from the influence of cold weather.

Anti seepage function: The composite drainage board has excellent anti-seepage performance, which can effectively prevent the infiltration of groundwater, avoid problems such as foundation settlement and soil loosening, and increase the stability and durability of the foundation.

Widely applicable: Composite drainage boards can be widely used in underground garages, basements, rooftop gardens, sidewalks, squares and other places of buildings, as well as in infrastructure construction such as parks, green spaces, highways, railways, etc., to meet the drainage, insulation, and anti-seepage needs of different places.

In summary, composite drainage boards have multiple functions and can provide comprehensive drainage, insulation, and anti-seepage solutions. They are widely used in the fields of construction and infrastructure, improving engineering quality and sustainable development capabilities.
