Product code: ROC-PLANTER
A massive, sculptural concrete planter that can also serve as a place to sit or a boundary element.
Roc Planter was designed by the architecture practice CAAS Architects. It is an urban element whose form and geometry help to separate different outdoor public spaces. The series' design was inspired by the broken-tile mosaic used in Catalan Modernist architecture: faceted three-dimensional surfaces form what looks like a shattered mosaic. Thanks to its size and construction, the planter serves several functions: it holds plants, but it can also become a place to sit, a landmark or a boundary element. The design is registered and protected by the European Union Intellectual Property Office.
The planter is made from through-coloured high-performance self-compacting concrete (HPC). The surface is treated to expose fine 1–12 mm white, black and grey granite aggregate – it resembles natural stone. The entire surface has a hydrophobic and anti-graffiti coating, and all edges are slightly chamfered.

Large city squares, pedestrian zones, office and residential spaces – where a single element needs to provide greenery, invite people to sit and separate traffic zones.
A planter weighing almost a tonne must be delivered and positioned with lifting equipment, so plan its location in advance. The Roc planter can be combined with Roc concrete benches and Roc Seat seating elements from the same series.
Concrete planters are heavy and stable, with a stone chip finish, so they also work as a natural barrier to traffic. Cor-Ten steel planters are much lighter, with modern shapes and a warm brownish tone, and go well with wood, concrete and greenery. Choose according to whether the planter needs to restrict traffic or mainly decorate the surroundings.
Concrete planters stand firmly without any fixings thanks to their weight. Cor-Ten planters are lighter, but they weigh much more when filled with soil. In locations exposed to wind, place tall, narrow planters on a level base, choose plants that are not too tall, or fix them to a wall.
Plants need drainage so that the roots do not stand in water. Put a layer of gravel at the bottom and a suitable growing medium on top. Cor-Ten planters have drainage holes in the bottom, so excess water drains away by itself.
A stable rust patina forms on the surface of Cor-Ten steel, protecting the metal and giving it a brownish tone. For the first few months, until the patina stabilises, the planter may leave brownish marks on light-coloured paving. So at first it is better to place it on darker surfacing or where such marks will not matter.
Yes, heavy concrete planters are often used to separate a pedestrian zone from the roadway and prevent cars from driving onto the pavement. Long planters are suitable for enclosing café terraces or small areas. This restricts traffic while also decorating the surroundings with greenery.
Concrete planters are heavy, so it is worth planning their location in advance – moving them later would be difficult. They are delivered and positioned with lifting equipment, and the largest models require a crane. The exact weight of each planter is stated in the product's technical data.
Yes. Concrete planters can be matched with concrete benches and waste bins in the same finish, while Cor-Ten planters go well with wooden equipment. Some planters belong to the same series as benches, so the space looks coherent.
