Hello Bettie,

Of course, it also depends on how thick you want the pipe and exactly which type of Poroton blocks you are using.
Is the wall going to be a thick, single-layer Poroton wall?
That shouldn’t really be a problem, but T9 to T7 blocks are actually more brittle than the uninsulated variants!

Regarding the anchors, there are naturally special anchors for each type of wall, and it’s definitely important to use those.
Usually, an anchor in Poroton goes through several layers, so they naturally have a higher load capacity than a simple drywall panel, where it’s already a bit risky to screw in a heavy shelf! There are also many pieces of furniture that explicitly prohibit mounting on so-called drywall partitions.

...For our house extension, we were recommended Poroton. Is it possible to properly install a pipe in it, or does everything just crumble apart?

Porous clay blocks (trade name: Poroton) are made from clay, loam, sand, and pore-forming agents (e.g., sawdust). The blocks are first dried at temperatures below 100°C (212°F) and then fired at around 1000°C (1832°F). Poroton blocks can be laid either as larger blocks with lightweight mortar or as plan bricks with thin-bed mortar. Since the thick-bed method with lightweight mortar has some disadvantages, only plan bricks should be used nowadays. The typical wall structure from inside to outside is: 1 cm (0.4 inch) interior plaster, 17.5 cm (7 inches) porous clay block, 10.0 cm (4 inches) external thermal insulation composite system (ETICS), and 1.5 cm (0.6 inch) synthetic resin render; if facing bricks are planned, the synthetic resin render is omitted, followed instead by a 4.0 cm (1.6 inch) air gap and then 11.5 cm (4.5 inch) facing bricks.

Regarding the structure of porous clay blocks, it goes without saying that a special wall plug must be used for fixing. Anyone who has ever hit an internal web (the internal supporting layer of the porous clay block), for example during kitchen installation, will confirm that it is highly sensitive to fast-setting cement. This can be frustrating, but “it does not mean everything crumbles apart.”

Kind regards
