Уналт: Шинэхэн бетоны уналт нь хүргэх бичиг баримттай тохирч байх ёстой. Барилгын талбайд авчрахдаа үүнийг нарийвчлан шалгах ёстой. Шинэхэн бетоны уналтад 3 удаа бетон цутгаж туршина. 14 диаметртэй дугуй ган баар ашиглах бүрт 15 ширхэгийг нягтруулна. Дараа нь туршилтын конусыг тэгшлээд 2-5 секундын турш татан авна.
