Summer is fast approaching and now it’s worth thinking about how to prepare a garden for the holiday season. A swimming pool is certainly an ideal option that not everyone can afford. A self-built wooden terrace is a good alternative – you can create a recreational area with couches or an outside dining room with a table, chairs and an umbrella necessary in the strong sun.
The garden terrace is an extension of the house, space for relaxation and meetings. Its location is not easy – from the south the heat can be felt, from the north there will be too little sun, from the west – a gusty wind teases. But every terrace can be arranged so that it is a nice and quiet corner.
Above terrace on concrete slab or terrace on the ground
A terrace built on the ground can be built in several ways. It is quite popular to make a concrete slab and finish it with frost-resistant ceramic or stone tiles. However, if you want to avoid major construction work, you can instead build a wooden platform, lay clinker brick or stone slabs or cubes directly on the hardened, but also water-permeable foundation.
Above-ground concrete terrace is most often built for new homes. Its popularity is due to the fact that it can be finished in many ways, and a well-made concrete terrace is durable and does not require too much care and maintenance.
Another type of ground terrace is also interesting – terrace on the ground. It is built faster than a concrete terrace, there is almost no wet work. And if you use the right finishing material – stones, clinker pavement or concrete slabs – such a terraced terrace will last even several dozen years.
Above-ground terrace on a concrete slab – construction and finishing of the terrace surface
First you need to prepare the foundation. For this purpose, humus is removed from the surface intended for the terrace and a layer of gravel is 12 inch thick, preferably in two layers – each of them must be thoroughly compacted mechanically.
Sand or lean concrete bedding is made on the foundation. Very careful performance of these layers is important because they protect the terrace slab from cracking caused by uneven settlement or frosting in clayey soils. In addition, it will not be necessary to reinforce the terrace slab, which is made of concrete. It is usually 4 inches thick. It should be dilated, i.e. separated from the walls of the house with a gap filled with elastic material (for example, a strip of properly cut foam board).
The surface of the terrace must have a 2% slope from the wall of the house towards the outside so that it can easily drain water. It is obtained by making a fall layer not less than 2 inch thick on the terrace slab from a fast drying concrete mix. The surface level of the terrace should be chosen so that after laying the surface it is a few centimeters lower than the floor in the house. If this is not the case, it may turn out that water flows into the house during the rain.
