LAYING
The Weser column is made up of interlocking elements laid on one another, and is mainly used as a decorative element. It can also be used as a structural element, under certain circumstances (the load must be calculated), for example to support terraces or pediments.

The Weser column must be laid on a reinforced concrete base, designed for the load it bears and for the type of ground underneath. A mastic joint is used between elements for waterproofing. Steel reinforcing rods must be used in the column, and it must be filled with concrete using the elements as formwork. The hollow core should be lined with a resilient material such as polystyrene or similar. This sheet will absorb differences of dilatation between the filling concrete and column elements in order to avoid any risk of cracking. To keep the column clean during filling, we recommend placing polythene sheeting over the capital.

During filling, avoid pouring the concrete from too great a height, and pour slowly, to avoid putting too much pressure on the lower elements. Clean any excess mortar immediately using plenty of clean water.
