It is important to drain properly around a house so that you do not get problems with damp.
Surface water must be led off away from the house before it permeates down into the ground. This is done by inclining the ground away from the house. You should also keep in mind not to let plants and vegetation go straight up to house wall, but instead place a layer of single or decorative stones closest to the wall.
Well-functioning drainage consists of drainage and capillary-breaking materials, such as macadam, insulation boards and drainage pipes. Today's drainage pipes are made of plastic, which makes them easier to lay out compared to brick or concrete pipes. However, there is a risk of them becoming obstructed if you are not careful when backfilling.
