Renovate the floor, often without alternative in the old building

Renovating floors that are decades old means much more than just renovation. Old filling and insulating material must be removed complex. Occasionally, even a major repair or the entire replacement of the wooden substructure is required. Nevertheless, a task that can be solved for DIY enthusiasts.

Redeveloping a floor that has been fallow for years and may even be in an old-style property is not an everyday task even for the most enthusiastic hobbyist. The proverbial act of strength should begin by getting an idea of ​​which materials were originally installed on top of each other in how many layers there and how Condition of the entire building fabric, including possible carrier, piping, electrical cable is ever. If you are not sure that everything is correct and appropriate, you should not hesitate to ask a professional surveyor for help.

The old material has to get out completely

In most cases, because: If the house has been around for several decades, it soon becomes apparent that at that time was built completely different in terms of the material used. Under creaking floorboards or porous and crumbling cement, next to a (hopefully still intact) wooden beam structure, straw, clay, sand or even hay will come to light, which would first have to be completely disposed of. Floor boards and loadbearing beams are exposed after exposure for stability, penetrated moisture and possible mold growth controlled, if necessary repaired or in case of doubt rather completely replaced.

Redeveloping the floor also means insulating

And specifically it is about moisture protection, an optimal one thermal insulation and the Impact sound insulationwhen the room is not just above a basement. It is also predicted that, as for almost every activity on the construction site, there is also a mandatory DIN standard for flooring work - in this case - "Comment and explanations VOB DIN 18365", Which is to be observed for the sake of their own safety but also for reasons of insurance protection.

Technologies for floor renovation

Three of the most important methods are briefly listed here:

  • Floor construction with mastic asphalt screed, a mixture of split, gravel, sand and bitumen. However, since this material is applied hot, it plays only a minor role in the private sector.
  • leveling screedin which, prior to pouring onto the wooden beam ceiling, a welded base must be fastened, which simultaneously serves as insulation and impact sound insulation.
  • dry screed (Great for do-it-yourselfers!): the elements are light, do not need drying time, and the underlying wood does not need to be protected against moisture.

Dry screed - uncomplicated and quick installation

Depending on the quality and material composition, the prices for renovating the floor for the dry screed are between 10.00 and 20.00 Euro / m2. After attaching a edge insulation for the Impact sound insulation and laying out the soil with paper webs as trickle is first filled with a bulk fill (available as a container of 50, 80, 100 liters in the hardware store) and smoothed with a drawing board. Thereafter, the screed elements, starting at the wall opposite the door of the room, laid, to the Step rabbet glued and finally screwed become. 24 hours later, the renovated floor is resilient and it may be started with the proposed flooring, such as laminate or parquet.

Tips & Tricks

Use materials as possible for the fill minerals, which offer a particularly good sound and heat protection and only a small static load for the wooden base of the floor.
