Installation of the terrace without permanent gluing

Trouble-free installation without adhesive, mortar, and grouting - the raised deck terrace system is a solution to many problems associated with traditional glued terraces.

Raised deck terrace without mortar or adhesive

More and more investors are abandoning the traditional method of gluing pavers to the substrate on the terrace. This is because a modern raised deck terrace without adhesive is more durable, easier to maintain, and significantly safer for the building structure.

The raised floor technology allows for the construction of a terrace without wet work - without gluing, grouting, or permanent connection to the substrate. The pavers rest pointwise on pedestals, creating a stable structure that is comfortable to use and install.

1. What is a raised deck terrace, i.e., a terrace without adhesive?

In a traditional terrace, all layers, including the paver and waterproofing, are connected to each other — the pavers are glued to the substrate, and the joints are filled with grout, which means the structure is permanently bonded.

The layers of a glued terrace look as follows:

  1. terrace paver
  2. adhesive
  3. waterproofing layer
  4. compression layer
  5. insulation layer
  6. slope layer
  7. structural slab

In contrast, in the raised deck system, the pavers are supported on adjustable pedestals or support pads. There is no need to glue elements to the substrate, which allows for complete disassembly of the structure at any time.

This system has many advantages, primarily protecting the building structure, but also offering speed of installation and the possibility of inspection.

2. Why does gluing a terrace cause problems?

In traditional systems, the most common faults result from:

  • moisture being trapped under the paver
  • water freezing in the adhesive layers
  • damage to the waterproofing membrane
  • thermal movement of materials

Water that gets under the paver has no way to evaporate, causing them to crack or the grout to crumble. In a raised deck system, the situation is different – water flows freely into the lower layers and does not accumulate under the surface.

3. How does a raised deck terrace without mortar work?

A raised deck terrace consists of:

  1. concrete paver
  2. terrace pedestal
  3. waterproofing membrane
  4. thermal insulation
  5. vapor barrier
  6. sloping layer with a 1.5-2% gradient
  7. bonding layer
  8. reinforced concrete balcony slab

4. Key advantages of a glue-free terrace

  1. No wet work

In a raised deck terrace, there is no need for adhesives. Mortars and grouts are also not used.

  1. Waterproofing protection

The absence of drilling and gluing reduces the risk of damaging it.

  1. Dismantling capability

Each paver can be removed individually for inspection.

  1. Speed of installation

The absence of wet work significantly shortens the working time, as there is no need to wait for materials to set.

  1. Height adjustment

Pedestals allow for correcting slopes even with large differences in levels.

5. Where does a raised deck terrace without adhesive work best?

The technology is used:

  • on balconies
  • on rooftop terraces
  • around swimming pools
  • on large development projects
  • around fountains
  • when renovating old terraces
  • on residential ground-level terraces
  • in restaurant gardens
  • at exhibitions
  • where service access is required.

It works particularly well on flat roofs:

6. Are terrace pavers without adhesive stable?

This is one of the most frequently asked questions about raised deck terraces, and the answer is - yes!

However, they must be spaced at appropriate distances (especially under additional loads such as planters, a pergola, or a jacuzzi), and the substrate should be stable and clean.

Standard 60x60x2 cm pavers are supported at the corners so that the system transfers loads evenly directly to the substrate.

7. Can a terrace without adhesive be renovated?

Definitely yes.

It is one of the best solutions for modernization because:

  • there is no need to remove the old waterproofing
  • unevenness can be hidden
  • the terrace level can be raised to the door threshold
  • installation is clean and quick
  • additional installations can be hidden under the terrace

8. Most common mistakes when installing without adhesive

The main mistakes during installation result from:

  • incorrect spacing of supports (without checking the paver's strength and design assumptions)
  • unstable substrate
  • lack of proper expansion gaps at structural elements and between pavers.

We have described them in more detail here:

Summary

Glueless terrace is a modern, system-based installation method that eliminates most of the problems associated with traditional solutions.

A raised deck terrace without mortar means:

  • no grout or adhesive
  • no water retention
  • no degradation of waterproofing
  • full serviceability.

This is not just an alternative to glued systems. It is a technological standard in modern construction
