Build a brick grill yourself

challenge walls

Grills are always built in exposed brickwork. To do this, use non-perforated fireclay or clinker bricks and refractory mortar. Used bricks are also quite good for this. They give the finished grill a rustic look. However, masonry is only as good as its execution. Equally sized setting and butt joints, fully jointed design without holes and lubrication points and an absolutely straight design are also decisive for a brick barbecue.

The correct overlapping of the stones is also important for the appearance and statics of the building. Masonry looks easy, but can drive the layman to despair. That is why you approach this work with respect and very good preparation. Then you too will succeed with the brick barbecue.


DIY Garden Grill | Well planned is half done

The most important thing in any construction project is the planning. Especially when bricking, “Just go for it” never works. So plan ahead exactly by answering the following questions.

  • Where should the DIY garden grill be?
  • What type and size of grill do you want?
  • What shape should the grill have?
  • What expansion reserves would you like to plan for?


A grill takes up a lot of space. In the winter months and when not in use, it often stands around quite uselessly in the way. In operation, it is a source of sparks, open flames and smoke. This is another reason to set up the grill as far away from the house as possible. All in all, a brick barbecue is an ideal project to put an unused corner of the garden to good use.

The grill variation

Brick grills come in many variations. The simplest variant is a grill station, into which you can slide in a gas grill. This basically only requires two socks, which you can use as extended tables. You can also set up a full grill, smoker and bake station by combining an open grill with a smoker and stone oven. Although the project is a bit more challenging, it will then become a real highlight in your garden, with which you can prepare the most amazing meals.


For simple, open grills, you have the E-shape, the S-shape, the X-circle and many other variants to choose from. Take a look around first and find the optimal shape of the grill for your garden.

Grill Extensions

You don’t have to put the really big project in the garden right away. Brick barbecues are well suited to being modularly expanded piece by piece. To do this, however, the overall concept must be in place right from the start. Be generous about it. The latest trend in garden design, for example, is the “ruin corner”. This is a somewhat larger building project.

If you can imagine such a project for next summer or the summer after that, include it in the planning of your brick barbecue today. In this way, you avoid having to tear down the grill, which was actually built for eternity.

Barbecue grill | minimum equipment

You can now find out what the DIY garden grill should at least have. As a minimum, your garden grill should contain the following elements.

  • Fireplace
  • Storage space for charcoal or firewood
  • Storage table for ready grilled dishes

If you plan for these elements from the beginning, then you have a good start for a great barbecue area.


Brick barbecue | Measure three times – build once

A plan is the prerequisite for building. After that, it depends on the exact execution. The next step is therefore the exact measurement of the batter board. Check each dimension several times before proceeding.

TIP: You can easily check the angles of rectangles by measuring and comparing the diagonals. In squares and rectangles, the diagonals must always be the same length. If they are of different lengths, you have a parallelogram and the bottom plate will be crooked.


A brick barbecue needs solid ground

Even if it is a lot of work, it is not possible without a solid and frost-free foundation. Frost-free means: excavate at least 80 cm deep. If you are planning a larger project, it is better to take a mini excavator. Even if you only need it for half an hour, your arms will thank you. Also think about the overburden: solid soil increases by 1/3 when it is dug up and thus loosened. You’ll be amazed at how high the hill can get once you’ve finished digging the foundation.

After the excavation, the formwork begins . To do this, fasten continuous formwork boards around your pit and support them well. Important: The formwork boards must all be exactly the same height and be absolutely straight. At best, you can install a gradient of 2%, then the rain will reliably run off to one side. In addition, the supports must not protrude beyond the upper edge of the formwork boards. After concreting, you can easily remove the concrete over the side formwork.

Before concreting, cover the bottom of the pit with foil. This will prevent rising damp and frost damage.


Concrete Slabs

You can use regular Portland cement and concrete gravel. Work with the cement mixer, it will save you a lot of power.

Mix in the following ratio: 1 part cement to 4 parts gravel.

The mix is ​​really quite simple. However, if you are not sure, use ready-made concrete in sacks. This gives you a durable and highly resilient foundation. Mix the concrete quite liquidly so that it spreads better in the formwork. After you have poured in a hand’s breadth of concrete, put in the wire mesh. Alternatively, you can also lay the wire mesh on a couple of paving stones before concreting. It is important that the lower mat does not lie completely on the floor.

When you have filled the formwork with concrete up to a hand’s breadth from the upper edge, insert the second reinforcement steel mat. If you have to split, make sure there is an overlap of at least three stitches. Now fill the formwork up to the top edge. Tap along the formwork a few times with the rubber mallet. This allows the concrete to set and compact.

However, work with liquid concrete to avoid the formation of bubbles. When the formwork is filled and tapped off, use the batten to level the concrete over the edge of the formwork. Now carefully smooth with the smoothing chip and cover the concrete with foil. Make sure that nobody walks on the formwork for the next 48 hours. In very hot weather, dampen the concrete a little with the garden hose. This will prevent the concrete from cracking. After two days, you can remove the formwork and foil.

Build a brick grill yourself !

When the foundation is in place, it’s time to start building. A brick barbecue needs full bricks, half bricks, three-quarter bricks and quarter bricks. Use the stone cracker to separate them. This is much quieter, more precise, safer and dust-free than the stone saw or the cut-off grinder.

TIP: For larger DIY barbecue projects, brick up the corners first. Measure the grill again exactly. A stone plus a joint has a length of 25 cm. Clamping a mason’s cord is particularly easy with the bricked and ready-tied corners.

For smaller grills, use a spirit level. This is a bit tedious, but with patience and concentration you will reach your goal. When building walls, always ensure that the layers overlap at least ¼ of each other. The next but one layers should always be straight on top of each other. This is how you get a decent result.

You can either build bricks immediately or scrape out the joints and re-point. If you prefer a rustic, Mexican style, then work with thinner grout and the same full grout. Wipe down the brickwork every two coats with the wet paintbrush. This creates an interesting structure and keeps the masonry clean from the start.

If you prefer the neat style, then scrape out the joints to a depth of about 2 cm every five coats. When the grill is fully built and set, re-point it with the jointer. This way you get a perfect, clean result.

Use the angle grinder to cut two pieces of the 10 gauge rebar. If you have bricked up to hip height, place the irons in the setting joint so that the grill grate then rests securely and without wobbling. Wall in the reinforcement bars firmly. But remember to always cover the grill. This will prevent the iron from rusting too quickly. Always rub the irons with oil after grilling. This also prevents corrosion.
