Umphathi-nkqubo uza kusebenzisa i-crack inducer okanye indlela efanayo neyokunciphisa ingxolo yokususa intloko yenqwaba ukuya kwinqanaba elinqumliweyo.
Umphathi-nkqubo kufuneka afake kwangaphambili i-crack inducer ukuze enze i-crack ibe yimpumelelo kwi-pile malunga ne-100 - 300 mm ngaphezulu kwe-pile head cut off level. Ii-pile starter bars ezingaphezulu kweli nqanaba mazisuswe kwi-concrete ngezinto ezifana ne-polystyrene foam okanye i-raber sponge. Xa kumbiwa ukwakhiwa kwe-pile cap, ii-pile heads ezingaphezulu komgca we-crack maziphakanyiswe kwi-pin yonke. Ii-100 - 300 mm zokugqibela ngaphezulu kwe-cut off level mazinqunyulwe kusetyenziswa ii-handheld zombane okanye ii-pneumatic hammers.
