Installing a hammock on the concrete ceiling or brick wall

Drill a hole in the ceiling

Drill an 87 mm deep hole with a 12 mm masonry drill bit

To ensure the correct drilling depth, mark the drilling depth of 87 mm on the 12 mm masonry drill bit with adhesive tape.

  • ⚠️ Take care of your safety! Wear protective equipment such as gloves and safety goggles when working and make sure you are standing securely. Get help if you are using a ladder. Please tie up longer hair.
  • Tip: First pre-drill with a smaller drill bit, this makes the strenuous overhead drilling easier.
  • Tip: To drill a nice hole and prevent the drill bit from slipping, switch off the hammer or percussion function of the drill for the first few millimetres.
  • Tip: While drilling, ask someone to collect the dust with a vacuum cleaner.

Tip: What to do with reinforced concrete?

Concrete ceilings are usually reinforced with a steel mesh.

It is best to use a cable detector to avoid these steel wires when drilling.

If you come across a wire while drilling and suddenly cannot make any further progress, please do not try to continue drilling. Instead, drill a second hole a few centimeters apart.

The incorrectly drilled hole can be easily repaired with repair mortar.

Drive in dowels carefully with a hammer

Drive in plugs carefully

Clean the hole with a vacuum cleaner or even better with a small brush.

First push the plastic plug into the hole by hand and then carefully hammer it all the way in with a hammer. Choose a small hammer and take care not to damage the plaster.

Screw the screw completely into the concrete ceiling using a sturdy screwdriver or similar.

Screw in the ring bolt completely

Screw the ring bolt all the way in with a screwdriver or, as shown here, with a rod so that the bolt covers the drilled hole.

Nothing should be visible from the shaft of the screw.
