Marka la barbar dhigo walxaha shaandhada guud ee tolan, shaandhada irbadda la feeray waxay leedahay faa'iidooyinka soo socda:
1. Porosity Large iyo hawada wanaagsan ee permeability, kaas oo hagaajin kara awoodda load ee qalabka iyo in la yareeyo khasaaraha cadaadiska iyo isticmaalka tamarta.Shaandheeyaha irbadda lagu feeray ee la dareemay waa maro shaandhada fibre-gaaban oo heersare ah oo leh habayn jaranjaray iyo qaybin dalool lebis ah, iyo porosity-ku waxa uu gaadhi karaa in ka badan 70%, taas oo laba jibaar ka ah marada shaandhada tolan.Isticmaalka maryaha irbadda sida bacaha shaandheynta waxay yareyn kartaa cabbirka bacaha waxayna si weyn u dhimi kartaa isticmaalka tamarta.
2. Hufnaanta ka saarista siigada sare iyo feejignaanta gaaska oo hooseeya.
3. Dusha sare waxaa lagu dhammeeyaa rogrogid kulul, heeso ama dahaar, dushu waa siman yihiin oo siman, ma fududa in la xannibo, ma fududa in la qaabeeyo, fududahay in la nadiifiyo, waxayna leedahay nolol adeeg oo dheer.Nolosha adeegga cirbadda la dareemo guud ahaan waa 1 ilaa 5 jeer maro shaandho la tolan ah.
4. Degganaanshiyo kiimikaad oo xooggan.Ma aha oo kaliya shaandhaynta heerkulka caadiga ah ama gaasta heerkulka sare, laakiin sidoo kale waxay shaandhayn kartaa gaaska gardarrada ah ee ka kooban aashitada iyo alkali.
