With the Alps always in view: the house is situated in a scenic area. For an all-around satisfactory quality of living, it was particularly important for the client to make the outdoor area attractive and homely as well. This has been enlarged as part of the renovation of the terrace and adapted to blend in visually with the adjacent interior.
Terrace and flat roof in one: a garage is located under the terrace of the Murnau property. Mineral glass foam panels fixed in place with PCI Pecimor DK bitumen adhesive therefore insulate the space against the cold and protect the upper covering against water vapour.
Installers used PCI Seccoral 2K Rapid fast-setting special waterproofing slurry to seal the upper side of the insulation panels. The fast-setting special waterproofing slurry prevents water ingress into the space below the terrace – this is a given.
The layer of drainage mats and PCI Pavifix DM drain and screed mortar acts like a support layer. The mat and mortar system ensures fast and immediate drainage.
The substrate is now ready for the tiles to be laid. A drainage system ensures that rain and storms present no risk to the subsequent layer of porcelain stoneware. Under the drainage, a system comprising a bituminous layer, insulating panels and a waterproofing slurry safety layer ensure the garage located under the terrace remains dry.
Exactly at the right height: the floor-to-ceiling windows which separate the living space from the terrace presented a special challenge. To prevent the new porcelain stoneware tiles creating a trip hazard, the construction professionals worked according to precise dimensions.
The installers used PCI Rapidflott fast-acting flowable mortar in conjunction with PCI Lastoflex polymer modified additive to cement the new 90 cm x 90 cm porcelain stoneware tiles to the Murnau terrace. The product mix is water-, frost- and weather-resistant, and therefore ideal for laying ceramics outside.
Consistent in every detail: the installers cut the large tiles exactly to size around the edges of the terrace.
A large number of floor-to-ceiling windows are installed in the building's façade. The floor tiles are laid evenly on the adjacent area. The installers therefore created a structure which manages to not interrupt the overall aesthetic while still being able allow water to drain away.
Pure relaxation in prospect: the renovated terrace invites you to stay at home. The large tiles are elegant and present a completely harmonious whole.

For a terrace to inject a small bit of luxury into the monotony of everyday life, not only is it necessary to carefully select the upper covering, it is particularly important to ensure the right technology is used for the substrate in order to meet the high requirements placed on it. A terrace in Murnau was therefore renovated and extended by professionals who used large-format fine porcelain stoneware tiles with the proven products of construction chemicals manufacturer PCI Augsburg GmbH. A special feature of the terrace is the underlying garage with the external section comprising a flat roof. In order to protect the space below the terrace against the ingress of water, a professional seal was installed including two drainage points. The construction professionals manufactured a particularly high quality, reliable and durable insulating layer from insulation panels of mineral foam glass, which were fixed in place using PCI Pecimor DK bitumen adhesive for insulation boards. The installers sealed the upper side of the insulation panels with PCI Seccoral 2K Rapid fast-setting special waterproofing slurry. This gave the garage a water-tight roof and a stable substrate for the tiled surface of the terrace. Drainage mats were placed on the previously installed waterproofing onto which the PCI Pavifix DM drain and screed mortar was applied. This acts like a support layer. By providing the entire covering with a grid structure, the mat and mortar system ensures fast and immediate drainage. The drain and screed mortar also protects against frost damage and reduces efflorescence. Before the installers laid the tiles using a special floating-bed mortar for porcelain coverings, they applied a scratch coat to the back of the tiles to ensure a better keying of the tiles and the tiling adhesive. PCI Rapidflott was used to lay the new quick-hardening floor covering. To turn the mortar into an even more ductile product yet more resistant to water, frost and weather, the installers added PCI Lastoflex polymer modified additive to the cement mortar mix. This is because tiling adhesives mixed with this relieve substrate stresses, balance out stresses resulting from temperature fluctuations and are waterproof and frost- and weather-resistant. The grouting of the covering should be highly elastic in order to compensate for the length variations of the large-format tiles during changes in temperature. This is why all grouted joints were sealed with the elastic, self-adhesive PCI Silcoferm S silicone joint sealant.
