Rizzle from the Portizzle
well have been asked to test fixing to wet under floor heating pipe system with porcel thin so first i tested the tile to see how much movement it would allow before fixing so put two battens at each end of a 1200x600x4.8 giving a 150 mm loading each end then loaded the middle to test deflection until the tile broke at 50kg i had 25mm down and 25mm up so over all 50mm of deflection at 55kg the tile broke so unless you suffer an earth quake there is plenty of give in the tile next built 2 boxs 1200 x600 and fixed the heating system in to the boxs then covered the system with mira floor screed .4mm above system .tomorrow i will fit the decouplars one is iso mat the other will be blanke permat then
tile .then leave to dry for a few days then see how much each can take .the plummer has said on site before you self level the system must be under 5 bar pressure so the pipes have exspanded more than when the system is run with heating at 2-3 bar
