Aco ExoDrain self-supporting grid gutter made of Corten steel and filled with concrete
The demands placed on drainage systems are becoming increasingly challenging. In addition to the basic function of good drainage, aspects such as appearance, ease of maintenance, available installation height and method of installation also play an increasingly important role. Standard gutter systems from concrete or polymer concrete have their strengths, but also have limitations due to the required standardization. The ExoDrain was developed with that in mind.
The ExoDrain consists of an external (EXO) "skeleton" made of CorTen steel (or stainless steel). This skeleton is filled with concrete, creating an extremely strong construction that offers many advantages.
The ExoDrain does not require any concrete foundation or further lateral supplementation with concrete on a sufficiently load-bearing surface. (Type I acc. To NEN-EN 1433). As a result, there is no ugly wide concrete strip on the road surface that is normally around 10 cm wide quickly. The gutter width and height can be adjusted to any situation (even slope and "counter shot" are possible). The choice of materials also makes it possible to fabricate long gutter lengths (up to 3 meters) and one-piece corner pieces. This ensures shorter installation times and a perfect end result!
Cast iron gratings can only be made in lengths of half a meter. If the grid cover is made in CorTen or stainless steel, lengths of up to 3 meters can also be produced. Because everything can be made to measure, the gratings can be produced entirely according to the customer's wishes. Of course, traffic tax must be taken into account!
