Dry-laid ceramic flooring: quick and easy!
Innovation in construction keeps surprising us, and this time we are presented with a system for installing dry-laid ceramic flooring, without the need to use adhesive mortar.
Are you thinking about changing the flooring in your home? I can already confirm that, by using OndaBlock ceramic pieces, it is easier, faster, and you can even do it yourself.
Now you can install ceramic floors without complications! The system is 8 times faster than traditional tile installation
The startup OndaBlock presents an innovative dry-installation system for ceramic flooring that uses recycled thermoplastic polymer as a substitute for adhesive mortar.
Structurally, the product is made up of two joined elements: the upper part is the surface of the porcelain flooring (at first glance, it looks like a traditional tile), and the lower base is a thermoplastic polymer with side anchors.

🟧 Note: Also worth seeing is the tile-laying robot, one tile every 40 seconds — almost nothing!
How does the system work?
The operation for laying these ceramic pieces dry is based on geometry and floating installation, that is:
- Assembly using curved edges: The polymer base incorporates an exclusive wavy-edge system that allows the pieces to fit together precisely, similar to a puzzle, without requiring special tools.
- Direct installation: It works by being installed directly over the existing floor (such as concrete, previous ceramic flooring, or parquet), provided that the surface is level, firm, dry, and clean.
- Grouting for stability: Although the installation is dry, the system requires the mandatory application of grout material between the joints of the ceramic tiles.
The final grouting seals the system, gives it maximum stability against use, and ensures its waterproofing

This new material, by not requiring preparation time for mortar or adhesive, nor waiting time for the bonding material to dry, makes this installation method much faster than traditional tile laying.
Not to mention the advantage of avoiding possible poor application of the adhesive mortar, waste, and many other problems that arise if you do not have a good, experienced builder. See the advantages in the following image:

The recycled polymer provides a certain structural flexibility that, combined with the requirement to leave a perimeter joint (a 5 to 10 mm gap between the floor and the walls, with sealing), allows the system to absorb natural thermal expansion without generating stress.
Obviously, we have to remember that you will almost certainly need to cut some pieces. So, at the very least, you need to be somewhat handy because you will have to use an electric angle grinder for cutting or a manual ceramic tile cutter.
Even so, especially for renovations where we already have a fairly level base floor, I see it as a practical and useful system where we can potentially save a few euros.
To point out one drawback of this system, the pieces in the catalog measure 60 x 120 cm, which is a heavy and inconvenient format to handle.
Frequently asked questions about OndaBlock
Can OndaBlock be installed outdoors?
Yes, OndaBlock can be installed in outdoor areas if the surface is stable, has a slope for water drainage, and the joints and technical conditions are respected.
Can OndaBlock flooring be stored outdoors?
Yes, temporarily, as long as it is protected from rain, moisture, direct sunlight, and excessive loads.
Does OndaBlock flooring have thermal expansion?
Yes. Perimeter and structural joints must be respected to allow movement.
Does the surface need to be flat and level?
Yes. OndaBlock does not correct unevenness or major defects in the base.
What unevenness tolerances does OndaBlock flooring allow?
A maximum of 3 mm with a 2 m straightedge and no localized irregularities greater than 2 mm.
Can it be installed over carpet or flexible materials?
It is not recommended. It must be installed over firm, rigid, and stable surfaces.
What is the maximum admissible moisture level?
As a guideline, 2% on cement-based substrates and 0.5% on anhydrite substrates.
Can an OndaBlock floor be installed without grouting?
No. Grouting is essential for the stability, protection, and warranty of the system. In addition, a perimeter joint — minimum 5 mm — is required next to walls, pillars, frames, and vertical elements.
Can an OndaBlock piece be placed directly over mortar?
No. OndaBlock is a dry-installation system that serves as an alternative to traditional mortar.
Can it be installed over underfloor heating?
Yes, if the system is stabilized, switched off 24-48 hours beforehand, and the thermal protocol is respected.
Can it be used in bathrooms or wet areas?
Yes, but the base must be waterproofed and properly executed, since OndaBlock is not waterproof at its joints.
Can an OndaBlock tile be replaced?
Yes, the system works in such a way that individual replacement is possible. Simply remove the grout from that area, cut the plastic waves that connect it to the adjoining pieces with a utility knife, remove it, and install a replacement module.
