ᐅ How do I securely mount Ikea Metod wall cabinets on rigid walls?

Hello everyone, I am currently facing a challenge with installing IKEA Metod wall cabinets in my new house. The walls are very rigid – concrete with a relatively smooth surface or possibly drywall over a concrete wall underneath. My main question is: how can I securely and permanently attach the Metod wall cabinets to such rigid walls without the brackets or anchors coming loose later or the cabinet sagging? I want to avoid the cabinet becoming unstable, as it will be quite heavily loaded. Are there specific anchors, screws, or installation methods you would recommend for these cases? I appreciate any tips, including advice on drill bits or tricks for wall preparation! Thanks in advance.

Hello Koleklo, your question addresses a common challenge when mounting wall cabinets on concrete walls. Here is a specific approach:

- First, use a drill: Use a powerful hammer drill with an appropriate masonry bit for concrete, ideally 6 or 8 mm (1/4 or 5/16 inch), depending on the anchors you have.
- Anchors: Choose high-quality expanding plastic anchors or, even better, metal anchors or heavy-duty anchors that grip firmly inside the drilled hole.
- Screws: Use stainless steel or galvanized screws with good threading that match the anchors.

Important: Before screwing in, clean the drilled holes thoroughly to remove any dust residue. For drywall installed on concrete, secure the mountings so that they reach the concrete behind, rather than just the plasterboard itself. If necessary, use a long drill bit to drill deep enough to reach beyond the drywall layer. This way, the cabinet will be securely attached to the structural wall. If possible, check the drilling locations with a detector to avoid cables or reinforcements.

I hope this helps you!

I would recommend metal expansion anchors for concrete and to use at least an 8mm (5/16 inch) drill bit. Simply screw in the screws until fully seated, hang the cabinet, and you’re done.

Please do not use standard plastic anchors only, as they often do not hold well in concrete. It is better to use heavy-duty anchors or metal expansion anchors. Pre-drill with the appropriate drill bit according to the anchor manufacturer’s instructions.

For drywall on concrete, you should fasten in a way that anchors into the concrete behind, not just load the drywall panel.

This is exactly what I find problematic: It is often assumed that drilling through drywall and directly into concrete is always straightforward. But are all the walls completely solid? Aren’t there areas with cavities or metal stud profiles that are easily overlooked?

My experience shows that you first need to carefully check where the actual load-bearing layer is located, and also ensure the correct type of anchor is used at the proper depth. Otherwise, you can easily cause structural failures that only become noticeable months later—especially with heavy cabinets.

It would also be interesting to know how Koleklo checks whether there is truly a solid concrete layer before drilling. Without that, even the best anchor choice can be useless.

Thanks for the valuable tip! I actually have a multi-detector (a combined metal and pipe locator) and will check the wall in several places beforehand. I roughly know the thickness of my exterior walls (about 20cm (8 inches) of concrete) – with drywall on the inside. I will try to make sure the drill bit definitely penetrates into the concrete and not just the drywall layer.

My goal is to achieve a solid anchor in the concrete. That’s why I’m also asking which type of anchor or expansion bolt you would specifically recommend if the concrete can be used as the load-bearing layer.
