Izizathu eziyinhloko: Okokuqala, uwoyela osetshenziswayo uxutshwa nomswakama, uthuli, amanye uwoyela ohlukahlukene kanye nempuphu yensimbi ekhiqizwa ukuguguleka komshini, okuholela kumbala omnyama kanye nokuthamba okukhulu. Okwesibili, uwoyela uyawohloka ngokuhamba kwesikhathi, wakhe ama-organic acid, i-colloid kanye nezinto ezifana ne-asphalt.
