Pulasitiki yamadzi ndi njira yabwino kwambiri yotetezera nyumba zogona zowonongeka. Zopangidwa pogwiritsa ntchito samenti ndi mchenga pogwiritsira ntchito kowonjezera kwa madzi a chitsulo cha chloride mu pulasitala, chomwe chiri ndi kuchulukitsitsa kwapakati, kusakaniza kumeneku kumasiyanitsidwa ndi mphamvu yowonjezera ya hydrophobicity.
Komanso, kutentha kwa madzi kumaphatikizapo pokhapokha kuti pulasitiki yamadzi imaphatikizapo mtundu wina wa simenti, mineral filler ndi polymer modifier, zonse zigawozi sizili poizoni ndipo sizimakhudza thanzi laumunthu.
Mtedza uwu umagwiritsidwa ntchito kuthetsa makoma m'chipinda chomwe chili ndi chinyezi chachikulu, monga bafa, dziwe losambira , m'chipinda chapansi pa nyumba, m'chipinda chapansi pa nyumba, pantchito yopangamira.
Pulasitiki yamadzi osatsekemera madzi amatha kumaliza makoma a njerwa, mwala, konkire, ndipo amamatira kwambiri zipangizozi. Kugwiritsiridwa ntchito kwa pulasitala kumagwiritsidwa ntchito patatha miyezi 4-6 yomanga nyumbayi, pamene kuphulika kwake kukuchitika.
Mitundu ya pulasitala
Pali mitundu itatu ya pulasitala yopanda madzi, yomwe imaphatikizapo zosakaniza zosiyanasiyana:
- mchenga wamchere, ndi zowonjezera zowonjezera kuchokera ku ma polima, zomwe zimapangitsa kuwonjezeka kwa madzi;
- phula la asphalt, lokhala ndi ozizira kapena otentha mastic, amagwiritsidwa ntchito zingapo;
- amathira madzi asphalt, omwe amatentha mastic, omwe amadzazidwa ndi simenti.
Njira zotsekemera zamadzi ndi zosakaniza zingagwiritsidwe ntchito panthawi yoyamba yomanga komanso kumapeto. Malinga ndi zomwe zimapangidwa m'zigawo za pulasitiki, zimatha kugwiritsidwa ntchito pakati pa nyumba yokhalamo ndi kunja.
