Here we focus on massive concrete pillars/columns/vertical elements-- both cylindrical and angular-- as a base for climbing plants. Trellis systems can usually be easily attached, but sometimes you may encounter free-standing posts/masts with a significant amount of rebar, which can make drilling tricky. In this case, alternative fastening methods include special tension straps, the fixing of the plants by means of binding material or "self-climbers." Find out more in the "Ideas" section under Pillars und Obeslisks.
Concrete columns are load bearing elements; that means they are supporting an existing structure and are usualy made of very pressure-resistant concrete that can make drilling difficult. It becomes more difficult to work with if the columns are covered with insulation. You can determine this simply by tapping and listening for a distinctly hollow sound.
As opposed to columns or pillars, free-standing elements like posts are designed to support light loads such as lights, signs, decorations, etc.. Structurally, they are reinforced by a high concentration of latticed, iron rods which means encountering resistance when drilling is unavoidable. Therefore, one should consider whether drilling holes to fit climbing aids is the most safe and effective method.
All of our 5 construction designs / standard kits are suitable for concrete pillars and posts, the ideal solution being our medium classic kit in combination with the cross mount WM 10081 with brass rawlplug, as the drilling depth is relatively shallow with these anchors-- drilling and fastening take place outside the rebar layer, making installation relatively simple. Please note, however, that the hole must be completely and flawlessly sealed so that no moisture can reach the reinforcing steel under any circumstances. This can be tricky on very thin columns, as the flat support washers of the cross mounts won't adapt sufficiently to the small radius and may have to be deformed at an angle.
