Types of floor build-ups

The floor structure is an important part of construction or renovation projects and there are various types available, such as screed, insulation screed, dry fillers, drainage mortar, and self-levelling compound. Each type of floor structure is specifically suitable for a certain space and offers different advantages, such as high load-bearing capacity, insulating properties, low height, or a sustainable solution.

When choosing the right floor build-up, it is important to consider whether the structure of the house is suitable, whether underfloor heating will be installed, and whether the floor will be placed on an upper level. Staenis offers floor build-up solutions that are easy to install, stress-free, and have unique advantages, such as a lighter design or an environmentally friendly dry floor.

- Choose a filler below: screed, (tileable) insulation screed, dry fillers, self-levelling compound or drainage mortar based on the room.

Screed

Height from 1 cm

Traditional screed, but 10x better reinforced

screed weight: ±100 kg/m²/7cm
very high load-bearing capacity
a room on the ground floor

Cracking, subsidence, detachment, etc. of the floor are eliminated by dividing the floor structure into very small sections of 0.25 m2. Due to this division, you no longer need expansion joints (except at door openings) or a decoupling mat. Tested by Ghent University, with inspection by the BBRI.

Laying screed yourself Possible screed floor build-ups

Insulation screed

Height from 4.5 cm

Insulating and 10x lighter replacement for screed

Dry filler weight at 7 cm, excluding grid, boards and floor covering: Insulation screed soft ±10.5 kg/m²
high load-bearing capacity
ground floor, upper floor or attic space

By applying insulation screed in the Staenis grid. The insulating screed can be tiled directly (tileable version) or OSB can be screwed onto the grid.

dry floor

Height from 6.3 cm

Dry fillers with a wooden finishing layer

10x environmentally friendly dry floor

Dry filler weight at 7 cm, excluding grid, boards and floor covering:
EPS beads ±1.0 kg/m² · Cork granules ±8.3 kg/m² · Aerated concrete granules ±35 kg/m²
medium to high load capacity
attic space

This is achieved by using dry fillers, as opposed to a traditional screed. The circular floor structure with Staenis grid is demountable and can be reused without waste.

Laying your own dry floor Possible dry floor structures

Terrace

Height from 4.5 cm

10x more sustainable and permeable terrace

weight of screed/drainage mortar: ±100 kg/m²/7cm
very high load-bearing capacity
terrace, the driveway or garden shed

By combining the Staenis grid with a draining infill material, you ensure that moisture and stresses do not affect the lifespan of your new terrace and you achieve a proper terrace construction.

Laying your own patio Possible terrace floor structures

Self-levelling compound

Height between 1 mm and 5 cm

Self-levelling, but 10x easier

weight of levelling compound: ±14 kg/m²/1cm
to place flat and at a slope
ground floor, first floor or attic

With the Staenis levelling grid, you can easily level and reinforce uneven subfloors.

Applying self-levelling compound yourself Possible self-levelling floor build-ups

Climate-neutral floor structure

Height between 10 cm and 25 cm

alternative to insulation screed, sprayed PUR, and screed

weight of the circular floor build-up: ±10 kg/m²
high load-bearing capacity
ground floor, first floor or attic

By using loose insulation materials in an acoustic circular floor build-up system with low initial CO2 emissions, a sustainable and reusable solution is created without waste.

Example weight of a complete lightweight floor build-up

This example uses an average of 7 cm of filler and excludes the existing subfloor and final floor covering.

Floor build-up	Example weight
Dry floor with EPS, green grid and 12 + 18 mm OSB	approx. 21 kg/m²
Soft insulation screed, grid and 18 mm OSB	approx. 23 kg/m²
Dry floor with cork, green grid and 12 + 18 mm OSB	approx. 29 kg/m²

The actual weight depends on the average layer thickness and chosen board build-up; the height difference alone is not enough for an exact calculation.

Do you have construction or renovation plans and want to get started yourself installing your floor structure? Fantastic, we love that hands-on mentality!

Do you want to renovate the bathroom, or perhaps redesign the attic space now that the children are a bit older? Or maybe it's time for a new terrace?

Does the new floor need to be insulated or acoustically perfect? Is the structure of the house strong enough for a new floor build-up? Will underfloor heating be installed? Will the floor be installed on an upper floor? And which floor finish will you choose?

You can already tell: every floor structure has different properties, and everyone has different requirements for their future floor. That’s why we are happy to help you!
