How to fix a screw in Porotherm blocks (WITHOUT breaking them!)
• Step 1: NO Hammer Drill! Always switch your drill to “Rotary” mode only. Hammering shatters the hollow webs.
• Step 2: Drill Slowly & Steadily. Use a good quality masonry bit and let the drill do the work.
• Step 3: The Magic Secret: Special Plugs. Standard plugs fail here! Use specialized hollow-wall anchors
• Step 4: Tap Gently. Push the anchor in until it’s perfectly flush with the wall.
• Step 5: Drive the Screw. Secure your fixture tight! The plug will knot up safely behind the hollow gaps.in
