Section of this waterproofing terrace:
• RC structures
• secondary waterproofing and vapor barrier, a unique product
• thermal insulation, just in case you are under the terrace is closed or heated space
• cement screed on the decline of 1.5%, a minimum thickness of 4 cm, separated from the thermal PE foil
• primary waterproofing
• adjustable floor support or adhesive for ceramic/stone/wood
• stone, ceramic, wood or concrete paving, raised without grouting and filling.
The advantages of such a system are:
• the whole system is transparent and does not come to capture and accumulation of water within the layers of the system
• rainwater immediately comes to waterproofing or the sewage system and in this way the final paving can very quickly dry after rain or washing terraces
• there is no continuous water pressure on the waterproof and therefore does not have to create acidic and harmful chemical ingredients
• Final paving can be completely set up horizontally as aesthetic works well
• control of the waterproofing is possible as well as possible repair the pavement layers can be easily dismantled and re-set
• This type of waterproofing system enables the final corner of the external paving stabilized or fully adjusted internal tiling, without fear that they will come to the entrance of water - the system without a threshold.
• It is recommended and it would be ideal to be completed when the reinforced concrete slab, the concrete mix "out" to catchment place with a fall of 0.5%.
• Secondary waterproofing and vapor barrier, through a unique product, are an essential element of the whole system. This layer will be ready to accept any kind of emergency water, water condensation or water trapped in the building, and he successfully directed towards transfer units. The recommendation for this film is a single-adhesive bitumen sealant and also a vapor barrier with a inlay aluminum mesh.
• As thermal insulation in this case, we recommend closed thermal structure - water-non absorbent structure, etc. Extruded polystyrene XPS or sprayed polyurethane foam. Thermal insulation on the terraces is not required except in cases where the under is closed or heated space.
• Lean concrete in fall shall not be less than 4 cm, should be reinforced with glass fibers and separated from the thermal insulation layer by PE film (plain nylon construction). The cement screed must be the continuous drop of at least 1.5% of the catchment areas, smooth and flat.
• The primary waterproofing is the key and most important layer of the system, and its quality has to be extremely high. For this sealing system, given the demanding and challenging post-installation construction period, primary waterproofing should be highly mechanically resistant, also very elastic, with a strong adhesion to the substrate, resistant to chemical compounds, bacteria, highly resistant to sudden temperature changes and the like.
Our recommendation is polymer cement waterproofing with adequate tape for bandaging corners.
• Adjustable floor supporters are generally self-adjustable for height, so that we can compensate for declines cement screed, set the final paving in the horizontal plane, another type of spacer is put as a fixed pad beneath paving. Both types of supporters evenly distributed elements in terms of paving widths, points ofIintersection, etc.

The drainage layer placed over a large area under the paving is very importnant element of the whole system. In case of seting up ceramics on the adjustable floor supporters, drainage layer is not necessary.
The role of the drainage layer is extremely positive and very important and therefore:
• there is no capture of water beneath layers of paving and paving took on various colors, and there is no appearance of stains
• drainage water travels quickly out of pavement layers and adhesives and paving dries quickly. This is particularly important in the continental regions of low temperatures.
• waterproofing was freed and relieved of the long-term presence of chemical "aggressive" water as it significantly increases the time of active exploitation
• drainage layer acting compensatory between different surfaces and layers, and not cracking stone or ceramic paving
• the paving is by means of these special drainage layers, you'll never see the ugly traces of saltpetre or calcified marks or stains.

• For the entire system and its functionality, are very important adequate drainage line or dot drains. Dotted drains should have the possibility of drainage water inlet with multiple levels.
