Nekuti izvo zvinhu zvakafanosanganiswa nemvura, zvinoda kushomeka kwemhepo kuti ifambise kuburikidza nehose pane yakaoma-musanganiswa shotcrete.

Imwe yemabhenefiti makuru ekunyorova-musanganiswa shotcrete ndeyekuti inoburitsa shoma rebound kana overspray pane yakaoma-musanganiswa shotcrete. Nekuda kwekuti zvinhu zvacho zvakafanosanganiswa nemvura, zvine kuderera kwekukurumidza kana ichibuda mumuromo, izvo zvinoderedza huwandu hwezvinhu zvinobvongodza kubva pamusoro. Izvi zvinoita kuti pave nemhoteredzo yebasa yakachena uye zvinhu zvishoma zvakaraswa.

Imwe bhenefiti yekunyorova-musanganiswa shotcrete ndeyekuti inoburitsa inowirirana uye yakafanana chigadzirwa pane yakaoma-musanganiswa shotcrete. Nemhaka yokuti kusanganiswa kunotanga kusanganiswa nemvura, pane zvishoma zvakasiyana-siyana muhuwandu hwemvura, izvo zvinogona kuguma nekuwedzera simba rakafanana uye kusagadzikana.

Nekudaro, wet-mix shotcrete inewo zvimwe zvayakaipira. Nekuti izvo zvinhu zvakafanosanganiswa nemvura, pane kushoma kutonga pamusoro pemusanganiswa dhizaini pane yakaoma-musanganiswa shotcrete.
