Tā 2018. gada augustā tika izveidots uzņēmums WPMEstonia OÜ, kas nodarbojas ar betona konstrukciju salaiduma šuvju un kontrolēto plaisu hidroizolācijas risinājumiem. Jau 10 gadus betona hidroizolācijai izmantojot kristālisko piemaisījumu, bija atklājušās šīs sistēmas vājās vietas. Kā risinājums tika izveidots tapas formas ​

Kas ir WPM CRACK INDUCER profils?

The WPM CRACK INDUCER profile is part of a three-part waterproofing solution or “white tank” method. The profile is designed to work with other WPM construction joint profiles and crystalline admixture.

By its nature, the WPM CRACK INDUCER profile creates a pin-shaped crack in the concrete structure when it adheres tightly to the concrete. Perpendicular to it is a perforated steel sheet with a mineral coating that makes the resulting shrinkage crack waterproof and thus prevents water from penetrating the building. The purpose of the pin-shaped crack is to maintain the strength of the structure so we can use the profile in load-bearing structures.

Kāds ir profila mērķis?

Profila mērķis ir vienkāršot dzelzsbetona konstrukciju hidroizolāciju un paātrināt betona liešanas procesu. Ja betona konstrukcijas parasti tiek uzlietas pa posmiem, lai līdz minimumam samazinātu rukuma plaisas, ko rada tilpuma saraušanās, betonam žūstot, tad, izmantojot WPM CRACK INDUCER profilu, varam kontrolēt veidojošās rukuma plaisas un hidroizolēt tās ar ūdensizturīgu tērauda loksni uz profila.

Kā ar WPM CRACK INDUCER profilu īsākā laikā ieliet vairāk betona?

As we know, concrete is a material that shrinks as it hardens, so it is necessary to consider this when constructing the structure. We can reduce the shrinkage by adding more reinforcement rebars to the concrete. In principle, if desired, it is possible to pour the concrete with a more considerable amount of reinforcement than usual without shrinkage. This means that if the amount of iron in the structure is such that the tensile strength of the reinforcement exceeds the tensile strength of the concrete, no shrinkage cracks will occur. However, this would raise the construction cost unreasonably high, and this approach is generally not used.

This is where the efficiency of the WPM CRACK INDUCER profile comes in. It allows you to keep the amount of reinforcement in the design reasonable and enable the profile to create controlled cracks exactly where we want them.

Because the profile allows us to control shrinkage cracks and make them waterproof, we don’t have to worry about accidental cracks when pouring large amounts of concrete at once. In this way, after the concrete has hardened, we can pour all the walls simultaneously. The same applies to the basement ceilings.

However, we would like to point out that the pouring pipe has to be as low as possible at the bottom of the formwork when pouring concrete into the formwork. In that way, it does not separate the concrete mixture into larger and smaller parts of the concrete if it falls to the base against the edge of the reinforcement. In this case, larger pieces usually fall to the bottom of the floor before and do not allow to form a dense concrete form around the construction joint profile or WPM CRACK INDUCER profile. This, in turn, is likely to cause water to seep through the structure. We have seen this problem times and times again over the years and have eliminated the consequences. From experience, we can make recommendations to help you avoid these costly mistakes.

We are aware of the routines of how concrete is poured. Still, in our opinion, a well-thought-out, careful, and perhaps a little more timely casting process outweighs the leaking structure, which must be re-waterproofed with additional resources later.

Kopsavilkums

WPM CRACK INDUCER profilam ir 2 mērķi:

• hidroizolēt plaisas, ko izraisa tilpuma samazināšanās;
• kontrolēt plaisas, ko izraisa tilpuma samazināšanās, lai vienā reizē varētu ieliet vairāk betona un ietaupīt laiku.
  

Neliels aprēķins parāda, ka WPM CRACK INDUCER PROFILA izmantošana betona konstrukciju liešanas un hidroizolācijas procesos dod ievērojamu priekšrocību gan naudas, gan laika ietaupījuma izteiksmē. Profils palīdz samazināt hidroizolācijas izmaksas gandrīz uz pusi, salīdzinot ar ruļļu membrānām vai citiem hidroizolācijas materiāliem.
