Olsem eria we i gat bikpela humiditi na planti wet insait long haus, 'waterproofing' bilong toilet i save afektim stret laip ekspiriens na laipspan bilong haus. Ol pasin bilong pasim wara i no inap go insait long wara i save yusim ol 'waterproof coating', we i no save kamap wankain na bihain ol i save bruk. Ol 'waterproof backing panels', olsem wanpela nupela samting we ol i wokim bilong dispela wok, i kamap olsem gutpela rot bilong stretim ol nupela ples waswas bikos ol i gat planti gutpela samting, na dispela i stretim hevi bilong 'waterproofing' long ol ples we i gat wara.
Wotaproof na moisture-proofing, pasim wara steam i go insait em ol bikpela gutpela samting bilong ol waraproof bek panel. Ol gutpela 'waterproof backing panel' i save yusim 'extruded polystyrene' olsem as bilong en, na ol i save bungim wantaim 'alkali-resistant fiberglass mesh na 'polymer waterproof mortar' bilong kamapim wanpela 'sandwich'-kain 'sealed structure'. Klostu-sel reit inap long winim 99%, na wara absorpsen reit inap long bosim aninit long 1%, na dispela i pasim rot bilong wara steam i go insait. Taim yumi skelim wantaim ol hevi bilong ol simen beis leia we i save kisim wara na wet, ol 'waterproof backing panel' inap long stopim ol 'mold' na 'peeling' long wol. Maski long ol ples we i gat planti wara longpela taim olsem ol ples bilong waswas, ol inap long mekim 'base layer' i stap drai, na dispela i rausim hevi bilong "no gat 'leak' long pes, tasol 'dampness' i stap insait long 'base layer'".
Strongpela strong na liklik kos bilong lukautim em i narapela bikpela samting bilong ol wara-pruf baksait panel. Ol samting bilong waswas i mas karim hevi bilong ol tail longpela taim na karim hevi bilong senis bilong tempereja. Ol baksait panel we wara i no inap go insait long en i gat bikpela strong bilong presim na strongpela 'dimensional stability', na i no inap long go liklik, go bikpela, o bruk taim wara i senis o tempereja i senis. Ol i save sapotim ol tail strong, na dispela i save daunim tru hevi bilong ol hul na bruk. Na tu, strongpela strong bilong ol long sakim weta i save mekim laipspan bilong ol i go longpela moa long wankain olsem bilong bilding yet, na i no gat wok long stretim na senisim planti taim. Taim yumi skelim wantaim ol 'traditional substrates' we inap long kamap lapun na bagarap insait long 1-2 yia, dispela i save daunim tru ol wokman na ol samting bilong wokim ol samting bihain, na dispela i save kamapim "wanpela-taim instolesen, longpela taim bel isi."
Wantaim gutpela konstraksen bilong en na em i ken mekim planti wok, dispela baksait panel we wara i no inap go insait long en em i gutpela tru. Hevi bilong en i no hevi tumas-hevi bilong en em wanpela hap bilong ol seramik tail-em i isi long karim na katim. Ol i ken putim long kain kain rot olsem 'dry hanging' na 'adhesive bonding', na i no nidim bikpela wok mentenens. Instolesen insait long 10m2 batrum i save kisim 2-3 de tasol, moa long 40% sotpela taim long ol tumbuna rot, na i no bagarapim laip bilong olgeta de. Na tu, em i helpim ol narapela narapela stail bilong bilasim haus; ol i ken putim 'tile' long en, penim, o putim long diwai o ston, na dispela i mekim na wara i no inap go insait long en wantaim gutpela lukluk bilong en. Em i ken kamap long ol toilet bilong famili, ol nupela flet we ol i stretim, na ol toilet bilong ol bisnis.
