How does the surface work in a raised deck terrace?
Choosing the surface is one of the most important decisions when designing a raised deck terrace. It is the finishing material that determines the appearance, durability, and comfort of use.
Unlike glued terraces:
- the surface is not permanently bonded to the substrate
- it rests pointwise on pedestals or joists
- gaps remain between elements to drain water
Thanks to this:
- water does not pool on the surface
- easy replacement of elements is possible
- the system is resistant to weather conditions

1. Ceramic (gres) pavers
The most popular solution in modern projects.
Features:
- high resistance to frost and moisture
- low water absorption
- easy to clean
- aesthetics (wide selection of patterns)
The most commonly used pavers are 60x60x2 cm
Applications:
- balconies
- home terraces
- housing developments

2. Concrete pavers
A more stable, solid, and durable solution than porcelain tiles. However, they are often thicker than 2 cm.
Features:
- high load-bearing capacity
- resistance to mechanical damage
- more rugged appearance
Disadvantages:
- higher water absorption than porcelain
- requires impregnation
Applications:
- garden terraces
- public spaces
- high-traffic areas

3. Composite Decking Boards (WPC)
A solution combining the look of wood with the durability of synthetic materials.
Features:
- moisture resistance
- no need for impregnation
- easy maintenance
- dimensional stability
Installation order: pedestals, joists, and decking boards.
Applications:
- residential terraces
- gardens
- balconies
4. Natural wood decking
Classic, warm, and the most natural solution.
Features:
- aesthetics of natural wood
- comfortable in use
- can be renovated
Disadvantages:
- requires impregnation
- sensitive to weather conditions
Applications:
- premium terraces
- lounging areas
- gardens

5. Natural stone
A premium solution used in prestigious or historic projects.
Features:
- very high durability
- unique appearance
- resistance to weather conditions
Disadvantages:
- high price
- greater weight
- brittleness - often requires the use of additional pedestals
Applications:
- hotels
- luxury projects
- representative terraces
- historic renovations
- heritage buildings
How to choose the right surface?
The choice of raised deck terrace surface should depend on:
1. Applications
- balcony → porcelain stoneware / WPC
- garden → concrete / wood
- roof → porcelain stoneware / concrete
2. Loads
- heavy loads → concrete / stone
- standard loads → porcelain / WPC
Loads require more attention, so they are worth analyzing more broadly, especially on public projects:

3. Aesthetics
- modern → porcelain stoneware
- natural → wood
- raw → concrete
- luxury → stone
4. Budget
- economical → concrete / WPC
- premium → porcelain stoneware / stone / exotic wood
Summary
A raised deck terrace offers great flexibility in choosing the surface material.
The most important options are:
- ceramic pavers (most versatile)
- concrete pavers (most durable)
- composite decking boards (most practical)
- wood (most natural)
- stone (most prestigious)
The selection of the appropriate material should always be tailored to the function of the terrace, technical conditions, and user expectations.
FAQ
