Preparatory works

Check the surface

The surface must be stable, load-bearing and free of loose dirt, sharp pieces and protruding parts. Check in advance where pipes, pipes, cables or ventilation ducts run.

Determine the total construction height

Take into account the height of CircoFloor, the short or long black adjusting screws, insulation filling, OSB, Durelis, Fermacell, Knauf Brio or underfloor heating plate, the final floor and all techniques under the floor.

Foil or vapour retarder

Place 0.2 mm PE film under CircoFloor in case of residual moisture, rising damp or a floor on open ground without a reliable moisture barrier. For cold surfaces, a vapour retarder on the warm side of the insulating layer may be necessary.

If you have any doubts about moisture or condensation, have the structure checked physically and avoid using two damp-proof layers.

Parts and names

White textured plate

The white plate from which the CircoFloor structure is built. Note the arrows at the top and the fins at the bottom to check the direction.

Black short or long adjusting screw

The black adjusting screw with which you adjust the height and pull the white structure plates towards each other. Choose short or long according to the desired build-up height.

Green locking screw

The short green locking screw with which you secure the top white structure plate, so that the structure plates can no longer click apart when walked on.

Direction of installation of the white textured panels

Place all white textured panels in the same direction. To do this, look at the arrows on the top and the fins at the bottom of the structure plate. The arrows and fins must follow the same direction.

Preferably continue working in the same direction. This way the threaded holes remain nicely aligned and the black adjusting screws and green locking screws can pull the plates together correctly.

top plate and bottom plate point in the same direction.

Good: top plate and bottom plate point in the same direction.

turned a quarter turn; the screw threads will then not fit properly.

Wrong: turned a quarter turn; the screw threads will then not fit properly.

How do you click the structural plates together correctly?

The strength of CircoFloor is because the white structural panels fully interlock. The black adjusting screw or green locking screw must not secure the plates at an angle. The screw must properly pull the upper and lower structure plates towards each other.

  1. First bring the white textured plates as close together as possible by hand.
  2. Use the double threaded holes to pull the plates together with your finger.
  3. Check whether the top plate and bottom plate are in the same direction.
  4. Only then tighten the black adjusting screw or green locking screw.
  5. Let the screw pull the plates together completely and stop when everything connects.

If the plates are difficult to click together, temporarily screw a black adjusting screw into an adjacent hole and rest it on the surface. This way you can put more downward force on the structural plates.

Wrong: plates are open and weakly secured.

Installing CircoFloor step by step

Placing the first white CircoFloor structure board on the table

The CircoFloor system is largely assembled on a workbench, allowing you to work comfortably without straining your back.

Start by placing the first white textured plate on the table.

Second white CircoFloor structure plate sideways in first clicks

Take the second white structure plate and click it sideways into the first white structure plate, so that they are firmly connected.

Pay attention to the installation direction; make sure all white textured plates are placed in the same direction for correct installation.

Placing the third white CircoFloor structural panel with arrow-shaped ribs

Add the third white textured plate to the whole.

Check the orientation on the inside of the structure plate; the ribs in the shape of an arrow indicate the correct installation direction.

Arrows at the top also indicate the correct direction.

Installing the fourth white CircoFloor structural plate with correct thread

Place the fourth white structure plate on the table and connect it to the previous plates.

The correct orientation is crucial to ensure that the threads match and the black adjusting screw fits properly.

Place the inverted structural plate in the center and click it into place

Place a white structure plate upside down and in the same direction in the middle and click it to the four surrounding white structure plates.

We call this assembled part a mushroom in this manual: four lower white structure plates, one upper white structure plate and one black adjusting screw in the middle.

Tip: to work faster and easier, assemble several mushrooms next to each other on the table.

Place the adjustment screw in the middle to connect structural panels.

Place a black adjusting screw in the center to connect the four bottom white texture plates to the top white texture plate.

Use of a screw gun with a custom bit for adjustment screw

Although a flat-head screwdriver is sufficient, it is faster with a screwdriver. Always use the screwdriver with the torque limiter or slip clutch engaged, so that the head of the black adjusting screw is not damaged.

Tip: sharpen a flat screwdriver to use as a bit in the screwdriver. Preferably use a hand screwdriver for the final fine adjustment.

Turn the adjustment screw to the correct height for efficiency

Adjust the black adjusting screw as close as possible to the desired height.

It is better to work straight away or just a little lower. Turning the system up a little afterwards is easier than turning everything down.

Place the first assembly on construction foil and substrate

Place the first composite part on the substrate.

PE foil on the substrate below CircoFloor

Check the foil before you continue building

If your project requires PE film or a vapour retarder, it must be installed correctly before you further expand CircoFloor. Complete preparation is at the top of this manual.

Back to preparatory work
Connect the second assembly sideways to the first

Make a second mushroom and connect it sideways to the first part.

Still pay attention to the placement direction of the white textured plates.

Determine the height of the CircoFloor system with a reference point

Determine the correct height of the CircoFloor system using a reference point.

Use a wooden slat with a pencil line to easily adjust the system to the correct height. Adjust the last millimeters carefully with a hand screwdriver.

Connecting two assemblies with a structural plate

Now also make sure that both mushrooms are adjusted to the correct height.

Work row by row. First connect two mushrooms laterally with an upper white structure plate over the length of 39 cm.

Only when four mushrooms come together do you place the remaining top white structure plate centrally between those four mushrooms. This order ensures that the plates align better.

Fix the system with the adjustment screw

Screw the black adjusting screw into the center of the additional white texture plate, with four meeting corners at the bottom, and allow the threads to mesh the top and bottom texture plates together.

It helps to push the white textured plates together by hand while screwing through the double threaded holes.

Fix the system with the adjustment screw

It is important that the white structural plates pull towards each other when turning the black adjusting screw. This way everything clicks together and the plates form a strong whole.

Check with each black adjusting screw that all white structure plates are properly assembled. If necessary, loosen the screw and try again.

Incorrect installation: white CircoFloor structural panels not fully clicked together

Make sure that the side click systems are always neatly put together and not as shown in the photo.

CircoFloor towers not clicked together properly

Make sure that the top and bottom white structure plates always fit neatly together and not as shown in the photo.

Continue building the system into a stable L-shape

Expand the system further. As soon as an L-shape is formed, the whole becomes more stable.

Further develop the system

Continue building the CircoFloor system according to the area you want to cover.

Further develop the floor system

It helps to connect several white textured panels in advance.

Place the structural plates on top and secure them with set screws.

Place the white structure plates on top again and fix the whole with black adjusting screws for extra stability.

Place green locking screws for extra connection

Now place the green locking screws as quickly as possible to firmly connect the top white structure plates to the underlying structure plates.

Further develop the system

Continue building the system until the entire floor area is covered.

Customizing the system by grinding with a grinding wheel

Use a grinder with a metal cutting disc to easily cut the system to size at the top and bottom.

By stacking multiple systems on top of each other and using a larger cutting disc, you can cut multiple structures to length at the same time.

Finish the edges with cut pieces and connect to the wall

Finish the edges of the system with the custom-cut pieces.

Depending on the top layer, you can fit precisely or somewhat less precisely against the wall.

When using a thicker OSB board on the structural boards, it is acceptable to stay a few centimeters away from the edge.

Connecting to the wall

Always pay attention to the direction of the cut pieces, as this is important so that you can use the double thread afterwards.

Place adjustment screws near the wall for extra load-bearing capacity.

Place set screws in the threaded holes near the wall for extra support.

Preferably choose holes with double threading for extra load-bearing capacity.

Screw green fixing screws into structural panels

Screw the remaining green locking screws into the white structural plates for a solid connection.

Placing frame screws in adjustment sleeves for fastening

In addition to each black adjustment screw, you can attach up to four frame screws to the surface.

Wooden base: pre-drilling is not necessary. Place one frame screw every 1 m² for extra stability.

Concrete surface: first drill a hole Ø 6 mm through the existing hole in the structural plate and then screw in the frame screw. Always insert at least a few frame screws to fix the system.

Do not over-tighten the screw; once it is firmly in the substrate, the system is secured. Thanks to the thread in the structural plate, you do not have to turn the screw all the way down; once it is firmly in the substrate, the system is secured.

Multi-layer parquet can be glued to OSB 3/4 board layer, provided that the CircoFloor system is anchored to the substrate with at least four frame screws per m² and the OSB 3/4 board layer is attached to the CircoFloor system with at least 13 wood screws per m².

7 extra adjustment screws for additional load-bearing capacity

To be able to glue tiles onto CircoFloor, the surface may only deflect minimally under a certain point load.

That is why it is important, when tiling, to place one extra black adjusting screw next to each green locking screw.

Even with floating floor coverings, the additional adjustment screws limit deflection, although this is not necessary.

In future versions, the structure will be made of fibre-reinforced plastic, making these 7 additional adjustment screws unnecessary.

CircoFloor system is flat and firmly attached to the surface

The system is now perfectly level and is firmly attached to the substrate.

Apply insulation granules

Only fill the system after the white structural plates are correctly assembled, the black adjusting screws are at the correct height and the green locking screws have been placed.

Fill the CircoFloor system with loose insulation material

You can now fill the CircoFloor system with insulation material in the form of loose granules.

Distribute insulation granules with a brush until the system is full.

Use a brush or a slat to evenly distribute the granules until the system is completely filled, including the spaces underneath.

You will now notice that the step sound is greatly dampened and the floor feels high-quality.

Compacting insulation granules

You can easily press the loose insulation with a loose white structure board.

CircoFloor system after insulation plating and finishing

After the system is insulated, you can panel it and finish it as desired.

Install OSB, Fermacell or underfloor heating

Check on the floor construction page which top plate suits your floor finish. The chosen plate determines the stiffness, span, point load and finish.

Screwing OSB boards onto CircoFloor with the correct screws

Screw OSB plates to the flat parts of the system. Use the white textured plates as a template to determine where to screw.

Always use screws with a diameter of 4.5 mm, which have a thread over the entire length, without a flat shaft, for optimum grip.

Place 3 screws across the width of the OSB plate every +- 40 cm. Placing 13 screws per m² is recommended.

One screw with a diameter of 4.5 mm has a maximum pull-out force of 40 kg.

Template for screwing OSB boards onto CircoFloor

You can also create a template yourself that perfectly shows where you can screw.

Working over pipes, conduits and obstacles

Placing utility lines under CircoFloor and keeping them accessible

Situation 1: there is sufficient height

When there is sufficient height, place CircoFloor over the pipe or pipe. The pipe remains free under the system.

  • Do not place the black adjusting screw directly on the tube.
  • Move the adjusting screw to a different threaded hole.
  • If necessary, place additional black adjusting screws on the left and right of the tube for extra strength.
  • Make sure the tube is not compressed.

Good: black adjusting screws are next to the tube.

Wrong: a black adjusting screw loads the tube directly.

Wide obstacle or pipe zone that CircoFloor works around

Situation 2: the pipe is too high

If the pipe is too high to place CircoFloor over it, treat the pipe as an obstacle or wall. Work with CircoFloor up to the pipe zone and then bridge with the top plate, for example OSB or a suitable gypsum fiber board.

Situation 3: ventilation duct or wide obstacle

For wider obstacles such as ventilation ducts, you work with extra support next to the duct. The span is determined by the top plate. Place additional black adjusting screws next to the obstacle so that the plate does not bend too much.

Resolve overhangs and edges

Sometimes CircoFloor cannot be placed completely against the wall or under an obstacle. In that case, the top plate can create a small overhang.

  1. Let the CircoFloor system stop slightly before the cantilever.
  2. Place a sturdy wooden slat or suitable edge support against the wall at the correct height.
  3. Screw this slat firmly into the wall or substructure.
  4. Allow the OSB or gypsum fiber board to extend over CircoFloor up to the lath.
  5. Check that the plate does not bend.

When acoustic decoupling is important, a hard connection to the wall can transmit sound. In that case, add a suitable acoustic strip or edge solution, or have the detailed structure checked.

the top plate continues to a sturdy edge support against the wall.

Principle: the top plate continues to a sturdy edge support against the wall.

Common mistakes

The adjusting screw is difficult to turn. What now?

First check whether the top plate and bottom plate are in the same direction and whether the threaded holes fit nicely together. Do not force the screw.

The structural plates remain open.

The plates are probably not completely aligned or the orientation is wrong. Pull the plates towards each other via the double threaded holes and tighten the screw again.

Can an adjusting screw rest on a tube?

No. Move the black adjusting screw to a different hole or place additional black adjusting screws next to the tube.

When do I install the green locking screws?

As soon as possible after the white structure plates and black adjusting screws have been installed. This means that the plates can no longer click apart when walked on.

How do I adjust the last millimeters?

Preferably use a hand screwdriver for fine adjustment. This way you can work more accurately and avoid over-tightening the screw.
