Here we focus on massive, concrete columns both cylindrical and angular, as a base for climbing plants. In terms of attachment, masts are particularly tricky as they contain a significant amount of rebar. 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" and "Masts".
Concrete columns are load bearing they consist mostly of very pressure-resistant concrete that provides a lot of resistance when drilling. It will be more difficult to work with if they are also covered with insulation. You can determine this simply by tapping and listening for a distinctly hollow sound.
As opposed to pillars, masts are free-standing and 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 effective and safe method.
From the FassadenGrün assortment, all standard kits are suitable for concrete supports, our most recommended solution being our Medium construction 'Classic' kits, combined with cross holder WM 10081 with brass rawlplug. This method suites these structures as all necessary drilling should remain above the level of rebar keeping it relatively simple to insert an anchor, please note however, that the sealing must be flawless to stop humidity penetrating the hole and surrounding iron.
