One of the biggest advantages that makes EPS Cement Sandwich Panel stand out from other prefab wall materials is its user-friendly performance when it comes to slotting. Many rigid wall panels are too brittle to cut, generating massive dust, sharp cracks and even dangerous flying debris when you try to make a groove for wiring. On the other hand, some ultra-soft lightweight panels deform easily after slotting, losing their structural integrity and affecting the overall stability of the wall. The EPS Cement Sandwich Panel strikes the perfect balance between hardness and workability, allowing even a junior worker with basic power tools to cut smooth, neat slots in just a few minutes.

To make a qualified slot on EPS Cement Sandwich Panel, you only need a common electric grooving machine with a diamond blade. First, mark the exact position of your wiring line on the panel surface with a pencil, then adjust the cutting depth to 20-25mm to match the diameter of your electrical conduit. Start the machine and move it along the marked line at a steady slow pace, and you will get a straight, clean groove without any surrounding cracks. The cement facing layer provides enough support to prevent edge collapse, while the inner EPS core cuts smoothly without producing large amounts of harmful dust. After you place the wires inside the slot, you can fill the groove directly with cement putty, and the repaired area will be as flat and firm as the original wall. This easy slotting feature saves construction teams hours of extra work on site, making every hidden wiring job far more efficient than using traditional brick or concrete walls.
