Here is an excerpt from the post:
Types of Pools
The main difference between different types of pools is how the basin is constructed. There are several different pool styles, each with its own advantages and disadvantages.
Above-ground pools are the cheapest construction option, as well as the easiest to build. Most above-ground pools are made from prefabricated kits, which even an amateur can put together (though most people go with professional installers). First, the installers level off the ground to form a flat building surface. Then they assemble a perimeter track, which supports the outer wall (made of metal, plastic or wood). Next, they spread sand in the pool area and lay the plumbing. Finally, they secure the vinyl liner over the pool walls, fill the pool with water, smooth the liner and fasten it into place. As soon as they hook up the pump and filtering system, the pool is ready to go. The main disadvantage of this sort of pool is that it’s less durable than other designs, and generally less attractive. It’s also less permanent, which can be a good thing — it’s relatively easy to disassemble the pool and move it to a new location.
Fiberglass pools are made from fiberglass-reinforced plastic, which has been molded into a basin shape. To install the pool, a construction crew digs an appropriately sized hole, lays the necessary plumbing, adds some sand filler and lowers the preformed pool structure into the hole. Then they level the pool, hook up all the plumbing and backfill in the area around the pool. Usually, the pool is surrounded by a concrete deck structure.
Vinyl-lined in-ground pools are a lot like above-ground pools, structurally, but they look more like conventional in-ground designs. The construction crew digs a hole and assembles a metal, plastic or wood frame wall around the hole’s perimeter. As in an above-ground pool, the crew lays sand along the bottom of the hole and secures the vinyl lining to the structural wall. These pools are a lot cheaper than other in-ground designs, but not as durable. Typically, the liner needs to be replaced every 10 years or so.
Gunite pools are the most popular design in much of the United States.

Mabwawa ya Kuogelea Hufanyaje Kazi? 21 Mar Je, Kuna Uwezo wa Kuogelea? Jinsi Bwawa la Kuogelea Inavyofanya Kazi Je, Wewe Ni Mmoja Wa Watu Wanaohitaji Kujua Kila Kitu Kuhusu Bidhaa Kabla Ya Kuinunua? Kwa wale kati yenu wanaodharau kununua dimbwi la kuogelea la nyuma la nyumba ambao wana aina hii ya utu, chapisho hili ni kwa ajili yenu! "Kama ilivyoelezwa hapo juu, ""Swimming Pools 101"" ni orodha ya aina za mabwawa ya kuogelea, pamoja na aina mbalimbali za vyombo, mifumo ya filtration, matibabu ya kemikali na kemia, taa, na kadhalika." Chapisho hilo lina michoro na picha zenye manufaa pia. Wakati umemaliza unaweza kuwa tayari kuanzisha kampuni yako mwenyewe ya bwawa la kuogelea la ndani! Kwa mfano, katika aina ya pool, tofauti kuu kati ya aina tofauti za pool ni jinsi ya kuunda. Kuna mitindo kadhaa tofauti ya mabwawa, kila moja ikiwa na faida na hasara zake. Mabwawa yaliyo juu ya ardhi ndiyo njia ya ujenzi ya bei nafuu zaidi, na pia ni rahisi zaidi kujenga. Bwawa la juu la ardhi hutengenezwa kwa vifaa vilivyotengenezwa mapema, ambavyo hata mtu asiye na uzoefu anaweza kuviweka pamoja (ingawa watu wengi hutumia wasanifu wa kitaaluma). Kwanza, wajenzi huinua jengo hilo kutoka ardhini ili liwe na uso tambarare. Kisha wao kukusanya perimeter track, ambayo inasaidia ukuta wa nje (kutengenezwa ya chuma, plastiki au mbao). Kisha, wao hutaga mchanga katika eneo la dimbwi na kuweka mabomba. Mwishowe, hufunga vitambaa vya vinyl kwenye kuta za dimbwi, hujaza dimbwi hilo maji, huyafanya vitambaa vyenye utulivu na kuvifunga mahali pake. Mara tu wanapoweka pampu na mfumo wa kuchuja, dimbwi liko tayari kwenda. Hasara kuu ya aina hii ya dimbwi ni kwamba ni chini ya kudumu kuliko miundo mingine, na kwa ujumla chini ya kuvutia. Pia ni chini ya kudumu, ambayo inaweza kuwa jambo zuri - ni rahisi kutenganisha dimbwi na kuihamisha kwa eneo jipya. Mabwawa ya nyuzi za glasi hutengenezwa kwa plastiki iliyoimarishwa kwa nyuzi za glasi, ambayo imeumbwa kuwa umbo la beseni. Ili kuanzisha dimbwi, wafanyakazi wa ujenzi kuchimba shimo ukubwa sahihi, kuweka mabomba muhimu, kuongeza baadhi ya mchanga kujaza na chini ya preformed dimbwi muundo katika shimo. Kisha, huunganisha maji na mabomba ya maji na kuziba sehemu iliyozunguka dimbwi hilo. Kwa kawaida, dimbwi hilo huzungukwa na sakafu ya saruji. Vinyl-lined in-ground pools ni sawa na juu ya ardhi pools, lakini wao kuangalia zaidi kama kawaida in-ground miundo. Wafanyakazi wa ujenzi hukumba shimo na kukusanya ukuta wa chuma, plastiki au mbao kuzunguka pembe ya shimo hilo. Kama ilivyo katika dimbwi la juu ya ardhi, wafanyakazi huweka mchanga chini ya shimo na kuunganisha vitambaa vya vinyl kwenye ukuta wa ujenzi. Mabwawa hayo ni ya bei nafuu sana kuliko mabwawa mengine yaliyo chini ya ardhi, lakini hayana nguvu nyingi. Kwa kawaida, liner inahitaji kubadilishwa kila baada ya miaka kumi au zaidi. Mabwawa ya Gunite ndiyo aina maarufu zaidi katika sehemu kubwa ya Marekani. Bonyeza hapa kusoma chapisho lote
