Description
Die Erfindung betrifft ein Verfahren zum Abdichten von porösen Bauflächen gegen Wassereinwirkung unter Verwendung einer wässerigen Lösung alkalischer Siliciumverbindungen.The invention relates to a method for sealing porous construction surfaces against the action of water Use of an aqueous solution of alkaline silicon compounds.
Zum Abdichten von Bauwerken werden neben den sogenannten Folien- und Bitumenwannen und dem wasserundurchlässigen Beton auch in zunehmendem Maße sogenannte Oberflächen-Dichtungsmittel eingesetzt. In addition to the so-called foil and bitumen trays and the Water-impermeable concrete is also increasingly used so-called surface sealants.
Bei einem bekannten Verfahren werden Alkalisilikate auf die abzudichtenden Bauflächen aufgetragen. Es hat sich aber gezeigt, daß Silikatlösungen, wie z. B. Wasserglas und Fluate zur Porenverdichtung unter Druckwassereinwirkung versagen, insbesondere, wenn in der Baufläche größere Lunker- und Kiesnester enthalten sind. Ferner hat sich gezeigt, daß diese ji Lösungen Ausbiühungen erzeugen können.In a known method, alkali silicates are applied to the building surfaces to be sealed. It has but it has been shown that silicate solutions such. B. water glass and fluate for pore compression under The effects of pressurized water fail, especially if there are large cavities and gravel pockets in the construction area are included. It has also been shown that this ji Solutions can produce efflorescence.
Ein anderes bekanntes Verfahren verwendet in Verbindung mit alkalischen Siliciumverbindungen eine Zwischenschicht aus Zementschlämme, die zum Verschluß der Oberflächenporen der abzudichtenden Baufläche dient. Diese Art der Oberflächendichtung, z. B. mit speziellen Zementschlämmen, erfordert einen feuchten, griffigen Untergrund und einen Schutz gegen zu schnelle Austrocknung, um die Bildung von Schwindrissen zu verhindern. -r.Another known method uses one in connection with alkaline silicon compounds Intermediate layer of cement slurry that closes the surface pores of the Building area serves. This type of surface seal, e.g. B. with special cement slurries, requires one damp, non-slip surface and protection against drying out too quickly to prevent the formation of To prevent shrinkage cracks. -r.
Es ist auch schon bekannt, flexible Dispersionen auf Bitumen-Kautschukbasis zu verwenden. Diese Dispersionen sind zwar auch auf feuchtem Untergrund anwendbar, weisen aber noch den Nachteil auf, daß vorhandene größere Poren und Lunker durch Luftpolster aufplatzen können und rückverdampfende Feuchtigkeit oft Blasen bildetIt is also already known to use flexible dispersions based on bitumen-rubber. These dispersions can also be used on a damp surface, but they still have the disadvantage that Existing larger pores and cavities can burst due to air cushions and re-evaporating moisture often blisters
Der Erfindung liegt die Aufgabe zugrunde, durch geeignete Kombinationen der vorbekannten Verfahren die Nachteile derselben zu eliminieren und ein optimales Abdichtungsergebnis zu erzielen.The invention is based on the object by suitable combinations of the previously known methods to eliminate the disadvantages of the same and to achieve an optimal sealing result.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die wässerige Lösung zunächst auf feuchten Untergrund aufgetragen, dann auf die eingezogene, jedoch noch feuchte Lösung eine Zwischenschicht aus Zementschlämme gestrichen und schließlich auf die erhärtete Zwischenschicht eine an sich bekannte flexible Dispersion auf Bitumen-Kautschukbasis aufgetragen wird.According to the invention, this object is achieved in that the aqueous solution is initially dampened Apply the substrate, then apply an intermediate layer to the absorbed, but still damp, solution Cement slurry is painted and finally a flexible layer known per se is applied to the hardened intermediate layer Bitumen-rubber based dispersion is applied.
Das erfindungsgemäße Verfahren weist mehrere Vorteile auf. Durch die Grundierung mit der Lösung alkalischer Siliciumverbindungen wird neben der Tiefenkristallisation in den Oberflächenporen, die größere Dichtigkeit und Festigkeit ergibt, auch eine bessere Verbindung der nachfolgenden Zementschlämme mit dem Untergrund erreicht und die Gefahr des »Aufbrennens«, d. h. der Vertrocknung der Zementmineralien vermindert. Durch die Zementschlämme werden größere Baustoffporen, Lunker u.dgl. gefüllt und ein geschlossener, griffiger Untergrund für die Bitumen-Kautschuk-Beschichtung geschaffen. Die Bitumen-Kautschuk-Beschichtung schützt bei rechtzeitigem Auftrag die Dichtungsschlämme vor zu schneller Austrocknung, wodurch die Rißgefahr und eine ungenügende Härtung vermieden werden und später auftretende Haarrisse (Schwindrisse) bis 0,2 mm Klaffung im Untergrund überbrückt werden.The method according to the invention has several advantages. By priming with the solution alkaline silicon compounds is in addition to the deep crystallization in the surface pores, the greater tightness and strength results, also a better connection of the subsequent cement slurry reached with the subsurface and the risk of "burning up", d. H. the drying up of cement minerals reduced. The cement slurry fills larger pores, cavities and the like and created a closed, non-slip surface for the bitumen-rubber coating. The bitumen-rubber coating If applied in good time, protects the sealing slurry from drying out too quickly, which increases the risk of cracking and a Insufficient hardening and subsequent hairline cracks (shrinkage cracks) up to 0.2 mm gap can be avoided be bridged underground.
Das erfindungsgemäße Verfahren ist vorzugsweise geeignet für die senkrechte Außendichtung von Kellerwänden, für die waagerechte Dichtung von Betonplatten, wie Unterbetonflächen und Schwimmbekkenböden. Es ist beispielsweise ferner geeignet zum Herstellen von Zwischendichtungen gegen aufsteigende Feuchtigkeit unter schwimmenden Estrichen, zur waagerechten Zwischendichtung unter keramischen Plattenbelägen auf Baikonen und in Naßräumen, wie Bädern und Duschräumen.The method according to the invention is preferably suitable for the vertical outer sealing of Basement walls, for the horizontal sealing of concrete slabs, such as sub-concrete surfaces and swimming pool floors. It is also suitable, for example, for producing intermediate seals against ascending Moisture under floating screeds, for horizontal intermediate sealing under ceramic Tile coverings on balconies and in wet rooms, such as bathrooms and shower rooms.
