Ka taea e ia te whakaiti i te putanga mai o ngā kapiti whakaata, nā te mea ka taea e te geogrid muka karāhe te whakawhiti i te kawenga kia ōrite me te whakarerekē i te ahotea o ngā kapiti whakaata mai i te ahunga poutū ki te ahunga whakapae, kia whakaitihia ai te ahotea o te paparanga uku.

2.2 Te whakapakari i te rori tawhito

Mō ngā papa tawhito, ka taea e te geogrid muka karāhe te mahi hei whakapakari. Ka taea e ia te whakapakari i te turanga oneone raro me te oneone ngohengohe, te whakapai ake i te kaha whānui o te papa, me te whakaroa i te roa o te ora o te rori.

2.3 Te ārai me te whakahaere i ngā kapiti whakaata

I muri i te whakakikoruatanga o te papa raima sima tawhito ki te mata raima uku, ka ngāwari te puta o ngā kapiti whakaata. Mā te whakatakoto i te mata whenua muka karāhe ka taea te ārai, te whakaroa rānei i ngā kapiti whakaata o te papa uku taketake, nā te mea he kaha kume pai, he iti te roa, ā, ka taea te urutau ki te whakarerekētanga o te papa.

3. Tikanga hanga

Ko te tikanga whakatakoto o te geogrid fiberglass ko ngā mahi e whai ake nei:

3.1 Te horoi i te iwi taketake

I mua i te whakatakotoranga o te geogrid muka karāhe, me horoi te paparanga turanga kia ma, kia papatahi, kia kore he paru, he hinu rānei.

3.2 Te whakatakoto i te mata o te oumu

Whakatakotoria te mata whenua muka karāhe ki runga i te paparanga turanga e ai ki ngā whakaritenga hoahoa, kia tino papatahi, kia kore hoki e miro.

3.3 Paepae pumau

Whakamahia he whao, he taura pupuri motuhake rānei hei whakau i te mata o te whare ki te paparanga turanga, kia kore ai e nekeneke i te wā e hangaia ana.

3.4 Te whakapūmau i te uku

Whakatakotoria te ranunga uku ki runga i te anga, ka whakakīkī kia hanga. Mā tēnei, ka mau te whatunga whenua muka karāhe ki roto i te hanganga o te huarahi.

4. Ngā Tuhipoka

I te whakamahi i te geogrid fiberglass mō te whakahou i ngā rori tawhito o te tāone, me aro koe ki ngā mea e whai ake nei:

4.1 Kōwhiringa rauemi

Kōwhiria he mata whenua muka karāhe kounga pono, kia mōhio ai koe kei te tutuki i ngā whakaritenga hangarau ngā tohu mahi.

4.2 Te kounga o te hanga

I te wā e hangaia ana, me tino aroturuki te kounga o te hanganga kia pai ai te whakatakotoranga o te mata o te whare, kia mau hoki, kia kore ai e miro, e poka rānei.

4.3 Te Tiaki Taiao

Kia aro ki te tiaki i te taiao i te wā o te hanganga hei karo i te parahanga ki te taiao e karapoti ana.

Hei whakarāpopototanga, he mea nui te whakamahinga o te geogrid muka karāhe i roto i ngā kaupapa whakahou rori tawhito o te tāone. Ehara i te mea ka taea e ia te whakapakari i te kaha o te hanganga ara me te whakapai ake i te mahi ratonga whānui, engari ka ārai hoki i ngā kapiti whakaata me te whakaroa i te roa o te ratonga o ngā rori. I te wā o te hanganga, me aro nui ki ngā take pēnei i te whiriwhiri rauemi, te kounga o te hanganga me te tiaki taiao kia pai ai te kounga me te hua o te kaupapa.
