ᐅ How do I mount Ikea PLATSA units on concrete walls?

Hello everyone, I am planning to install an Ikea Platsa system on a concrete wall in my living room. The wall is quite solid and smooth, so it is not a brick or timber stud wall. My specific question is: Which types of anchors and fastening methods are recommended to securely and permanently mount the Platsa units to concrete walls?

I have seen that the furniture is prepared for wall mounting, but the instructions mostly refer to wooden walls or drywall. Since concrete requires different types of anchors and screws, I want to make sure I use the right products without risking the furniture slipping or the installation becoming unsafe.

Additionally, I am interested in any tips on preparing the wall surface: Do I need special drilling techniques or drill bits, is a regular hammer drill sufficient, or would a rotary hammer be better? And how should I best handle the fact that Platsa consists of individual modules carrying weight—how many fasteners are advisable?

I would be very grateful for any targeted advice, including from personal experience!

Hello Tikineo, your question is very well formulated and shows that you value a secure installation. For concrete walls, heavy-duty anchors or bolt anchors are best. These ensure that the weight of the PLATSA modules is safely supported by the wall.

For drilling, I definitely recommend using a rotary hammer with a suitable concrete drill bit. A hammer drill can work if it has enough power, but the rotary hammer is generally more efficient and creates cleaner holes.

It is important that the anchors match the screws and are rated for the load – 8mm (0.3 inch) anchors are often standard for these types of furniture on concrete walls. Plan at least 4 attachment points per module, and more depending on the weight and size.

Before installation, make sure to thoroughly dust off the wall so the anchor holds optimally. If the PLATSA system becomes very heavy, additional metal brackets can be added to help distribute the load.

If you want, I can also provide a list of products I have personally used.

I want to go into more detail here because there are different types of heavy-duty fasteners for concrete that vary in suitability depending on the substrate and load. Basically, you can distinguish between:

- Chemical anchors (injection mortar) – optimal load capacity and highly recommended for thick concrete layers
- Expansion anchors (metal or plastic) – user-friendly and quick to install
- Bolt anchors/heavy-duty anchors – very strong, especially for heavy loads

If your wall is made of solid reinforced concrete, a rotary hammer with a suitable SDS-Plus drill bit is essential. This allows you to create clean, precise drill holes, ensuring the anchors hold firmly. The drill depth should be about 10 mm (0.4 inches) deeper than the anchor to remove dust and ensure proper anchoring.

Regarding screws: make sure they are galvanized or corrosion-resistant, otherwise, they may rust over time, especially if the wall is exposed to moisture.

I also find it important to align and test everything before final assembly to make sure the fasteners fit well. With the IKEA PLATSA system, individual modules can be adjusted later, but a secure frame installation will save a lot of hassle.

Do you have an idea of how heavy the planned installation will be? This would help estimate the load better and recommend specific anchor sizes.

Is there a specific estimate of how heavy the planned installation will be?

Good question! I’m planning to install about 3 to 4 PLATSA modules, each measuring 60x40x40 cm (24x16x16 inches). The total weight including contents, mainly clothes and books, will be around 70 kg (154 lbs).

The wall is actually reinforced concrete with a smooth surface. I was thinking of using four mounting points per module, so between 12 and 16 anchors in total. Does that make sense, or would more be necessary?

I want to keep the effort manageable but also be certain that the system holds securely without any swinging or risk of falling.

For the anchors, I was considering heavy-duty toggle bolts or possibly chemical anchors. The complexity you described makes me a bit concerned whether this is still feasible for me as a DIY enthusiast.

A quick note about the drill: I have a good rotary hammer with an SDS-Plus chuck, so it should be suitable for the holes needed.

Looking forward to more advice!

From my perspective, that is a very good approach. With 3 to 4 modules and a total weight of 70 kg (154 lbs), four fixing points per module are optimal to distribute the load evenly and ensure stability.

Since you already have an SDS-Plus rotary hammer, working with heavy-duty anchors is technically feasible. I would recommend using metal expansion anchors, as they provide an excellent balance between effort and safety. Installation is less complex than with chemical anchors, which also require some experience to handle and need a curing time.

Important points during installation:
- Drill the hole to the exact required depth
- Thoroughly remove the drill dust using compressed air or a brush
- Insert the anchor carefully
- Screw in galvanized or stainless steel screws to prevent corrosion

Metal expansion anchors with a diameter of 8 mm (5/16 inch) or 10 mm (3/8 inch) are ideal for these loads. These anchors secure themselves by expanding inside the drilled hole and provide very good holding strength.

If you connect the modules horizontally with brackets as well, you can distribute the load even better and prevent the modules from tipping forward.

Conclusion: Your plan is technically sound, and with precise execution, this will certainly be a very reliable installation.

I completely understand your concerns. I felt the same way when I had to fix my furniture to concrete. It can seem quite intimidating at first, especially if you don’t work on projects like this regularly.

What helped me was preparing everything carefully before the first drill hole: having all tools ready, checking drill bits and anchors, and watching videos on how to take safety precautions.

The most important lesson was to be patient while drilling and avoid applying too much pressure, so the drill bit doesn’t overheat or slip.

Maybe you could do the installation with a partner, which makes it easier to hold the modules securely while screwing them in. Also, take your time to ensure the fastenings are solid instead of rushing.

I personally felt comfortable using metal expansion anchors—if you drill clean holes and remove dust thoroughly (I also used a vacuum cleaner to help), the anchors hold really firmly.

If you like, I can explain in more detail how I did it, or you can ask specific questions about certain steps here.
