Thepa le tšebeliso ea metsoako ea lik'hemik'hale bakeng sa seretse sa phofo se omeletseng
Phapang ea bohlokoa pakeng tsa lisebelisoa tsa seretse le lisebelisoa tsa konkreite ke hore seretse se sebelisoa e le sekontiri se katiloeng le se tlamang, 'me ka kakaretso ke mohaho o mosesaane ha o sebelisoa, ha konkreite e sebelisoa haholo e le thepa ea mohaho,' me chelete e boetse e le khōlō. Ka hona, litlhoko tsa ho sebetsa ha kaho ea konkreite ea khoebo ke haholo-holo botsitso, mokelikeli le bokhoni ba ho boloka metsi. Litlhoko tse ka sehloohong tsa tšebeliso ea seretse ke ho boloka metsi hantle, ho kopana le thixotropy.
