SL combination floor vs Compofloor
An SL composite floor is frequently used when replacing ground floors in existing homes. Like other wet construction and composite floors, this system is designed for renovation projects requiring a new structural floor. However, there are clear differences in construction method, execution, and suitability for renovation that make a significant difference in practice. Compofloor is increasingly considered the more sophisticated solution for renovations when comparing both systems.
What is an SL combination floor?
An SL composite floor is a floor structure that combines various elements into a single structural floor. The system usually consists of a load-bearing layer that is filled on-site with a concrete pour. This creates a sturdy floor with sufficient load-bearing capacity.
This type of floor is frequently used in renovation projects, but technically it is closely related to traditional concrete solutions. This has specific implications for execution, scheduling, and disruption.
What is the main difference?
The main difference between an SL combination floor and Compofloor lies in the construction method. An SL combination floor is a wet construction system that relies on concrete pouring and drying time. Compofloor is a fully prefabricated, dry-construction renovation floor, designed for quick and controlled installation. This difference directly impacts the renovation time, habitability, and risks during installation.
Disadvantages of an SL combination floor during renovation
In renovation projects, an SL composite floor has several clear disadvantages. Pouring concrete always requires a drying time, which prolongs the renovation and makes rooms temporarily unusable. This increases the inconvenience, especially in occupied homes.
In addition, concrete requires additional logistics, planning, and curing monitoring. The floor structure is also less flexible with existing foundations and crawl spaces. Instead of adapting to the house, the house must adapt to the system.
Compofloor: developed as a renovation floor
Compofloor was designed from the ground up for existing buildings. The system consists of prefabricated floor cassettes that are installed dry and finished completely airtight. No concrete pouring is required, and therefore no drying time.
The floor is lightweight, foundation-friendly, and quick to install. It can often be installed in a single day, after which finishing work can continue immediately. This makes Compofloor particularly suitable for renovations with minimal disruption.
Independent comparison and quality difference
An independent comparison of flooring systems, conducted by Koppens Vastgoed, shows that Compofloor is rated higher in quality than comparable systems. The comparison considered structural performance, feasibility, and suitability for renovation.
It is precisely the combination of lightweight construction, dry construction, airtightness and foundation-friendliness that makes Compofloor the better solution in the comparison.

Why Compofloor is more often chosen in practice
While an SL composite floor is primarily a technical compromise between concrete and renovation, Compofloor is designed entirely from the perspective of renovation practice. No wet construction, no long waiting times, and no additional load on the foundation.
This makes Compofloor the most predictable and future-proof choice for many homeowners, property managers and consultants when replacing a ground floor.
How does Compofloor work in practice?
You can compare floor systems on paper, but it helps to see how they're constructed in broad terms. What does a renovation floor actually look like? And what happens during installation? This animation gives you a clear overview of Compofloor's construction. You'll see how the floor cassettes are installed, how the system connects to the existing foundation, and how the new ground floor is constructed step by step. Seeing how the system is constructed makes it clear why this solution is often a logical and foundation-friendly alternative to heavier or wet construction methods in renovations.
Choose a floor that suits renovation
When renovating, you want a floor that adapts to the home, not the other way around. Compofloor was developed with that in mind and is therefore more suitable for existing buildings than systems that rely on concrete and drying time.
Want to know if Compofloor is the right choice for your situation? It all starts with assessing the foundation and floor structure. Especially during renovations, Compofloor often proves to be the most logical solution.

Frequently asked questions about SL combination flooring
What exactly does 'wet construction' mean for an SL combination floor?
An SL combination floor requires concrete pouring on site, which involves wet construction with drying time and a risk of delays due to weather conditions.
Why might an SL combination floor require additional foundation inspection?
Due to the higher weight and the concrete structure, it must be checked in advance whether the existing foundation has sufficient load-bearing capacity.
How do concrete and drying time affect renovation planning?
The required curing of concrete delays the finishing process, making renovations in occupied situations logistically more difficult than with prefabricated floor systems.
What are the risks associated with pouring concrete in an existing home?
Pouring concrete carries risks such as moisture damage, irregular hardening, and additional loads on old foundations, especially where crawl space is limited.
Is an SL combination floor suitable for renovations with underfloor heating?
This is possible, but often requires an additional construction layer and therefore disrupts the floor levels, which can cause connection problems with existing thresholds.
Why do residents often choose Compofloor for an occupied home?
Compofloor is installed without wet construction, causes minimal disruption, and is usually ready for finishing within one day, making it suitable for habitation.
What makes Compofloor more predictable in terms of costs and planning?
Because the system is prefabricated, dry-assembled and has no drying time, costs and lead time can be accurately estimated in advance.
