Stone caisson

Art. 88-465
An easy-to-install 138 l module absorbs up to 96% of the water volume, which is 4-5 times more than a conventional trench drain, and requires a smaller cavity, thereby reducing excavation costs substantially. One module is sufficient for a surface area of 25 m². Dimensions: 50 x 50 x 55 cm. The robust design means that the area above can be trafficked. Duct for pipe connection. Specially-designed geotextile also supplied. Several modules can be connected together to form a module system able to cope with greater volumes of water and larger surface areas. Can replace anything from a small trench drain to larger systems for storage and recovery.
