Sound insulation on concrete floors: how to tackle it
Do you want to reduce sound transmission through a concrete floor? In this article, we explain step-by-step which construction effectively insulates against concrete subfloors.
What materials do you use for soundproofing a concrete floor?
A concrete subfloor naturally possesses a lot of mass. Unlike a wooden floor, it is therefore often not necessary to add extra mass plates. The focus with concrete is on dampening impact noise, such as footsteps or falling objects. This is achieved by applying a so-called floating screed. Below, we explain step by step how to achieve this.
In 4 steps, make a concrete floor soundproof
Step 1: Apply a vibration-isolating layer
Lay a layer of vibration-isolating material, such as EASYbond, directly onto the concrete floor. This layer absorbs impact noise and prevents vibrations from spreading through the structure.
Step 2: Attach a edge strip along the walls
Place an edge strip of vibration-isolating material along all walls. This strip ensures that the floor structure does not make direct contact with the walls, preventing sound vibrations from propagating through the construction to the walls.
Step 3: Attach OSB or underlayment boards to the insulation layer
Install OSB or underlayment boards on top of the vibration-isolating material. Using planks with a tongue-and-groove connection usually requires only one layer. If standard straight boards are used or if the floor is heavily loaded, it is advisable to place two layers in a staggered pattern. Ensure that the boards do not directly abut the wall but connect to the insulating edge strip.
Step 4: Choose a suitable finish
Finish the floor with a coating of your choice, such as laminate or PVC. Make sure the finished floor remains clear of the wall and connects to the insulating strip along the edges. This prevents impact noise from still being transmitted via the walls.
