Flooring Installation


Our classic tongue and groove profile is the result of centuries of experience: Tapered, the joint is wedged together when the floorboards are joined. This principle of "positive" connection opens up a wide range of applications. Depending on thickness it can be installed either glued, floating or screwed. Tongue and groove flooring is also excellently suited for more complicated applications such as renovations or restorations. However, this connection must always be expertly glued or screwed.

Tight joint
properly glued
good stability
versatile applications
glued, floating or screwed installation
excellent also for more complicated applications
ideally suited for renovations/restorations
proven for centuries


Simply better: our lock-it profile locks the floorboards purely mechanically - without using glue and without tools. The advantages of this is a simple, quick and perfect installation. The profile is interlocked in one operation, automatically aligning the floorboards at the face end. Individual floorboards can thus be easily replaced at a future stage. A prerequisite for this form of floating installation is a totally level surface.

Purely mechanical, positive interlocking

no glues or tools required
floating installation
simple, fast and perfect
on completely level surface
easy completion
face and longitudinal installation possible
therefore new design possibilities
installation can begin in the center of the room
Installation Options

FLOATING INSTALLATION: By gluing the floorboards tongue and groove fashion or by interlocking the lock-it planks, the floor is able to expand over its entire area. Admonter recommends the floating installation method for projects with no special requirements concerning room sound, very large surfaces and expansion gaps.


Short installation time
Little or no formation of gaps
Comfortable to walk on due to its natural flex
Reduced impact sound
Adequate for the installation on under floor heating systems
Lower requirements concerning the subfloor than with full-surface gluing


If you keep a distance of 10 to 15 mm from the wall so that the floor is able to expand, there are no disadvantages with the floating installation.

FULL-SURFACE GLUING: With this installation option the planks are glued onto the subfloor (mostly screed). Both the tongue and groove as well as the lock-it system are perfectly adequate for this installation method. Attention! Make sure to use flexible glue. Admonter recommends the full-surface gluing particularly for projects with special requirements (installation of large surfaces, reduced room sound etc.) such as museums or restaurants.


Continuous installation of larger surfaces
Perfectly adequate for underfloor heating systems (better heat conduction)
No swelling
Low expansion of the total surface which enables the use of silicone joints instead of skirting boards


High subfloor requirements
Long installation times
No elasticity when walked on as the floor is firmly connected to the ground

INSTALLATION ON FLOOR JOISTS: This installation method is mostly used in order to level out uneven subfloors. Planks with a tongue and groove profile and a thickness of 21mm are perfectly suitable for this installation type. Make sure that the distance between the single floor joists does not exceed 60 cm. Admonter especially recommends this installation method in combination with all types of renovation projects.


Environmentally compatible as no glues etc. are used
Firmly fixed to the floor which prevents swellings
Comfortable to walk on thanks to its natural flex


Height of the construction
Creaking noises cannot be avoided completely


Admonter flooring is a genuine natural product which means that the colour variations of each individual floorboard are as varied as nature. Prior to installation, it is particularly important to sort the individual planks by colour. By doing this, it is possible to deliberately influence the overall appearance of the room, depending on how the boards are sorted. If the floorboards are installed by merging the colour gradually, the result is an even, homogenous effect, while a more rustic look is created when bright and dark planks are deliberately mixed. As a result it is possible to create an entirely different effect in the same room, depending on how the floorboards are installed.
