Sewatek wall penetrations allow flexible construction of different feed-through assemblies, depending on the line pipes. However, you generally need to have made the penetration decisions before you place an order with us, as we need specific and precise information about the pipes and the structures to fulfil your order.
Detail images and marking instructions can be found on our Downloadable files page. When specifying the required service penetrations, we need to know how thick the structure is, what sort of pipes are to be fed through (material and size) and what the centre-to-centre distances of the pipes in the pipe group are. When this information is already presented in the penetration and element drawings, quantity surveying is best done based on these documents. Heating and water pipe drawings are usually not as useful because evaluating the centre-to-centre distances and the placement of the heating and water pipes in relation to each other is more difficult from these documents.
