Winter colds caused some cracks and separation of drainpipes (25 mm). Although repairing drainage systems (gutters and drainpipes) is usually rather simple, this time baseboard elevation that was covering the pipes caused us some problems. We had to dismantle elements of the elevation and after repairing them – install those elements again. We covered fixed pipes with mineral wool and proper foil. The elevation looks like new, which you can check by looking at the building of the Institute of National Remembrance in Warsaw. Installing elevations is also not a problem for us.
