KeraSafe installation was no problem for a professional

The Kiilto KeraSafe waterproofing system was easy and quick to install at Finland’s first KeraSafe site in Pori.

At the building site for the Aurinkoranta apartment block, the KeraSafe system was used to insulate one residential floor’s worth of wet rooms. Experience on the new water proofing system was received from eight apartments. Site manager Tomi Setälä of Lemminkäinen views the installation as trouble-free.

“If you have ever wallpapered anything, you are certainly able to install the KeraSafe waterproofing sheets on the walls. KeraSafe was described as quick to install, and this turned out to be true as soon as we got used to the process,” says Setälä.

Construction professionals quickly get the hang of new things, and this was also the case with the workers at the Pori site. According to Kiilto’s Regional Manager Jarmo Peltonen, normal waterproofing of a 30 m2 bathroom takes approximately one day.

“But a professional can prepare two to four bathrooms a day using the KeraSafe system,” Peltonen says, describing the savings.

Proper waterproofing in one go

The KeraSafe waterproofing sheet is approximately 0.6 mm thick. The layer required has an invariable standard thickness, which also makes technical inspection more efficient. The glue is first spread on the wall, and the sheet is then set in place. After the corner reinforcements and the feed-through pieces are installed, the insulation is ready as soon as it is dry. It pays to be exact in the preliminary preparations. The surfaces must be smooth and well cleaned. The bases must also be vacuumed carefully. When installed, the sheets will overlap by 5 cm, and the alignment line is marked to make installation easier.

“If a sheet develops a wrinkle or a hole, it can be easily fixed. The 5 cm rule also applies in this case. The attaching is done with KeraSeal hot melt glue,” says Peltonen.

The bridging ability of the cracks in the KeraSafe system is in the highest category: 3. If a tile is damaged and must be changed, the insulation is not easily broken, and the changing of the tile is easy to do. Due to the good experiences received, Setälä says that KeraSafe can be used on future sites too:

“When installing, you quickly get the hang of it, and the work proceeds quickly.”
