Abstract
En fremgangsmåte for festing av stenformasjoner, f.eks. l tunnel- og bergbygg, gjennomføres ved Injeksjon av vandlge tilberedninger av melamlnharplks- og/eller urlnstoff-formaldehydkondensater sammen med en sur herder. Som herder anvendes vandlge opplesninger av hydrogensulfatsalter, særlig opplesninger av alkall- og/eller ammonluinblsulfat. Herderoppløsnlngene kan l tillegg inneholde hjelpe- og aktlvstoffer som korro- sjonslnhlbltorer, strukturglvere og vedheftlngsfor- mldlere. Foretrukne harplksoppløsninger for festing med disse vandlge herdere Inneholder, for å eke brukbar- heten, spesielt for å forlenge lagrlngsevnen, en tilsetning av zeolltt NaA og/eller hydrosodalltt.
