Eadmer, a monk who lived during the 12th century, left a record that the Norman Canterbury Cathedral had been built upon the site of a Saxon cathedral - the second largest cathedral in the world exceeded only by St. Peter's Cathedral in Rome. Over the centuries, no one paid any attention to this story since the Saxons were believed only capable of building straw huts or wooden halls at best - that is until 1993 when a MULTIBETON floor heating system was installed. After removing the original stone floor, the 12th century legend was found to be true. Moreover, under the Saxon cathedral, which dated back to the 6th century, even older remains were discovered from Roman times. Construction was started on the Canterbury Cathedral, as we know it today, beginning in the year 1070.
In 1993, the English general contractor MULTIBETON Ltd. installed a MULTIBETON floor heating system in 830 m² of cement floor. Piping was secured to the armouring using cable binders. So-called "Breathing Floors" were used on the Norman foundation which require no vapour seal. The 25 mm mortar bed resting on a layer of sand was again covered with the original 50 mm thick renovated stone slabs. Room temperatures of 18 °C can be achieved based on a heating capacity of approximately 100 kW.
