Decrease in the screeds

Ladies and gentlemen, we have a terrace house in 1996 acquired a turnkey basis. After about two years, we have cracked all the expansion joints between the marginal ridges of the tiles and the tiling. In the fall of the floor was so serious that has been achieved in some places about 2 cm lower. We have let this nachfugen again. Now, after four years we have across our living room (width 4.5 m) a crack in the entire row of tiles. I suspect that the surface is broken underneath. In addition, numerous other border tiles are hollow knock again () and some have already broken. For screed preparation we have found that the yellow mats, is applied to the material that existed only in part from residues / snippets. Despite reference to the construction company is At no workaround. Since we ourselves have tiled, but only after ok by the construction company (moisture measurement in the neighboring row house). What can / should we do? The tiles are no longer available and the crack is to see a month more. Thank you!

Screed

Regarding the edge reductions, further studies on the structure, type and thickness of the concrete, joint classification, base realignment and residual moisture content. The transverse crack is directly related to the above to assess criteria. More options and such causes can only by a visual inspection on site be taken by a professional engineer. First of you should immediately write a written notice of defects to your contractor. Dipl.-Ing.

Screed

Dear Mr. Klimm,

the marginal reduction and thus the tear of the joints to VOB are not a lack of coverage. Shots lungs in cement screed are unfortunately common, because the cement floor in the rule (I claim to at least 99%) is not the DIN Built-appropriately. There seems everything has already hinted Mr. Kunert, even on serious installation errors. This survey is, in fact, only through an assessment on the ground. I would also like you and especially Mr Kunert in this context to a new Trockenestrichsystem, which we introduce the time on the market and auftachen not the problems of the type described above. Information can be found at www.best-estrich.com. You can contact us with questions you might also call 06 429 92340th

Best regards Volker Schlosser,

Screed

Dear Mr. Klimm,

the marginal reductions will certainly not by a defective floor. According to your description is a common pattern of damage that can occur in cement screeds - keyword: "dishes - caused by shrinkage. Which happens especially when the assignment was too early. - The floor edges were aufgeschüsselt. After drying, has lowered the plate, the edge joint is open. The crack is probably due to the clamping of the Estrichpatte done, ie determined to have the tiles, grout against the wall run. You should contact a specialist company to run operations for tile work of the now necessary to allow rework. Preservation of evidence and advice to help you in the matter further, unfortunately not. Other cracks and subsidence occur now, after almost four years, at least not more. - PS you can not confuse. About 99% of the screeds are installed so that there is no damage to the floor / pavement.

Dear Mr. Abert,

certainly is an indication of 99% is too high, this is also to be understood more metaphorically. You know that there are many installation errors. On the basis of the fitting according to DIN (whether this is always a good idea is debatable), so you will rarely find a building practice in the construction site, where all rules are followed when installing. I would love to talk like once a screed on the subject, especially to our new Trockenestrichsystem with you. Tel: 06429 92340 Id be happy about a call.

Yours sincerely,

Volker Schlosser

Daß ca. 99 % der Estriche mangelhaft verlegt werden, wie Herr Schlosser dies behauptet, ist falsch. Bei Ihnen könnte es wirklich um einen Verlegefehler handeln. Es kann auch eine zu frühe Belegung mit Fliesen sein, oder Einspannungen an den Rändern. Meist sind es mehrere Ursachen, die dann den Schaden auslösen. Wenn Sie bei roter Ampel über eine Kreuzung fahren, muß es nicht zu einem Unfall kommen, erst wenn von der Gegenseite zu gleicher zeit ein Fahrzeug kommt, kracht es. So ist es meist auch bei Bauschäden. 1.Ist die Gewährleistung abgelaufen? 2. Wenn nein unverzüglich schriftlich Rekamieren oder eine gerichtliche Beweissicherung einleiten.
