Technical description of balcony waterproofing
Existing Substrate
All the surfaces must be free of materials from previous constructions crews such as bricks, plasters, cables, rubbish etc. Our constructions crews carry out the final surface cleaning for the application of Terbobeto®. After the cleaning, is used the laser to obtain its final level to be laid (altitudes).
Primer adhesion
Application of asphalt varnish with high adhesion
First waterproofing
Coating of the first THERMODIEN NERO membrane 4kg -10οC which is perpendicular to the slopes coated widthwise 15cm & along 15cm between the rolls, while the joints widthwise do not coincide.
Special system pieces
Special membrane pieces are installed to further strengthen the system seal. The special pieces are placed on the perimeter parapets.
Balcony filling
The application of the Τherbobeto® heat-proof fiber reinforced lightweight concrete is performed by our specialized crews and with the use of a special press. After the coagulation of Terbobeto®, follow the scratching to its surface to be within the allowed tolerances and to be smooth and clean for the application of the final surface. Scratching of the surface is done after one to three days, depending on the weather conditions.
Waterproofing with Flex thermo
The final waterproofing of the balcony is made by installing a flexible FLEXTHERMO white two-component sealer that creates an elastic waterproofing membrane and offers great adhesion. It is recommended to reinforce the first layer with 5mm, 160gr / m2 A-FIBERGLASS MESH hard-wearing glass mesh to prevent cracks from the stresses that transferred from the substrate.
Perimetric joint of expansion
Perimetrically, in all masonry, a thermojoint foam is placed at a height higher than the final level of the substrate to form expansion joints with the masonry.
The tiles should be placed without cutting the thermojoint foam. After the installation, the foam is cut, sealed with a suitable material and the skirting board is placed without any contact with the floor tile.
According to national specifications, additional expansion joints may need to be based on m2 and surface geometry filled with Terbobeto®
Final surface
After seven days, you can proceed with the application of the final surface (tiles, marbles, laminate, etc.)
