MIA Drain drainage mat

Drainage mat with geotextile on both sides. Drainage mats are often used instead of gravel drainage layers, mostly on membranes and hard surfaces such as stone and concrete. Used for horizontal or vertical drainage e.g. at parking decks, bridges, landfills, etc. Several options available, depending on site requirements.
Installing a drainage mat is a good solution that can replace several time-consuming work stages. The drainage mat acts as membrane protection, drainage and separation layer. Therefore, the drainage mat also saves space, so the building height can be lowered significantly when building e.g. roof gardens.
