Terrace on the ground , compared to a traditional terrace on a concrete slab, finished with frost-resistant tiles, is a great way to build a terrace quickly and much cheaper. It has many utility advantages, and repair of any damage is also easier. See step by stephow to build a terrace on the groundwhat layers to lay andhow to insulate the terrace on the groundand see the diagram showingcross-section of a terrace on the groundWith this guidebuilding a terrace on the groundturns out to be very simple!

Why is it profitable to build a terrace on the ground
" One of the most popular methods of making a terrace is still resting it on a concrete slab and finishing with frost-resistant tiles. There is nothing wrong with that, only a fairly simple question remains - what for? This solution, although technically absolutely correct, is quite expensive, prone to damage and very time-consuming to implement. It is also somewhat final - we can hardly change the deck covering, but reshaping it without reorganizing the complete construction site is impossible. Similarly, repairing damaged pavement elements can pose a lot of problems. "
Meanwhile, the terrace can be made much easier, faster and, above all, many times cheaper, by choosingground terrace It is all a matter of changing the idea of a finish made of frost-resistant tiles glued on a concrete slab to paving stones or terrace slabs. The pavement treated in this way is basically nothing more than a slightly larger pavement, and its execution is not much different from laying a regular pavement.
"Differences between a traditional slab terrace anda ground terracebegin during the construction phase. The construction of a traditional terrace on a concrete slab usually takes about a month. About thirtyterraces on the groundcould probably be built during this time, because the last one can be completed in one … day! "
"At the same time, for the price of one traditional terrace, you can make almost twoterraces on the ground(the cost difference is about 40 - 50% in favor of the latter). However, in order to avoid problems with use and to enjoy a beautiful terrace for many years, work on it should be done correctly and in accordance with certain rules.However, in the case ofconstruction of a terrace on the groundmuch less (compared to a terrace on a concrete slab) and they are easier to meet. "
Cross-section - design of a terrace on the ground. As the planned level of the terrace is higher than the upper level of the anti-moisture insulation, it will be necessary to make an additional layer of protection. The structure of the terrace is assumed to not hold water, so the role of the insulation will be mainly to cover the existing plaster.

Insulation of the terrace on the ground
The first and most important condition, paradoxically, not so much to the terrace as to the building to which the terrace will be adjacent.It is about making sure that the wall is properly insulated against moisture and that it extends above the planned surface of the terrace. If this is not the case, it is necessary to make additionalinsulation of the terrace on the ground , protecting the wall against moisture.
The situation is very simple ifterrace on the groundis done simultaneously with the building, but it becomes a bit more complicated if we decide to make the surface next to an existing building. It is worth remembering that the dimpled foil is not a damp insulation. The insulation layer should be additionally protected against mechanical damage by sticking plates of extruded polystyrene with a thickness of 2-5 cm. They will also provide additional thermal insulation, but most of all, they will protect the waterproofing layer against puncture, e.g. when paving stones or compacting the substructure.

How to design a terrace on the ground
Another element that absolutely should not be neglected isground terrace designWhatever, prepared by a professional or hand-drawn on a checked sheet - it allows you to estimate the amount of materials needed , choose the optimal shape and anticipate possible problems that will arise when webuild a terrace on the groundWhen designing, you should also provide for the height of the terrace (it is good that the terrace surface should be 2-3 cm below the edge of the openings on the ground). leading him), and declines ensuring proper dehydration. The latter should always be designed from the building, with a slope of 1-2%. This means that at 1 m in length, the level of the terrace should drop by 1-2 cm.
Then you can start the actual earthworks related toconstruction of the terrace on the ground .
Building a terrace on the ground - step by step
Step 1 - channeling for the terrace on the ground
We start with korytowania, i.e. remove the top layer of earth, the so-called Hummus. Depending on the idea for finishing the edge of the terrace, the soil obtained in this way can be used to form slopes or laid out in the garden.
There are, however, some restrictions. Not every soil is suitable for embankments. The so-called cohesive soils, i.e. clays and loams. A slope made of such a material would wash out very quickly due to its very low moisture permeability. The soils with too high permeability (sands) are also not very happy, but not for structural reasons, but rather due to the impossibility of ensuring soil moisture appropriate for the plants growing on the slope.
Clay sands are best for slope forming, which can be additionally mixed with gravel. Like the foundation, the material of the embankments should be laid in 10-20 cm layers and compacted. It should be remembered that the best and easiest way to stabilize slopes is to plant them with vegetation, although you can also use, for example, concrete openwork slabs.

Step 2 - foundation and protection of the edge of the terrace
The next stage, which cannot be omitted whenconstruction of the terrace on the groundis carried out, is the construction of the foundation and securing the edge of the terrace.We make the foundation, as in the case of pavements, of aggregate compacted with layers. Curbs, palisades or garden lawn can be used to protect the edges. Much depends on the height of the terrace above the natural ground level and the way the slopes are developed. With high terraces, it is worth consulting a specialist, perhaps retaining walls or other means of soil stabilization will be necessary.
Step 3 - execution of the surface of the terrace
The last element of the construction of the terrace on the ground is the execution of the surface. This stage is also no different from making a pavement. For this, you can use, for example, paving stones or patio slabs. In the case of the latter, you can also make a ventilated terrace (laid on special supports). It will allow, among other things, to eliminate the threshold at the terrace door.
