So this morning,We went up stairs to have a quick revise over the different timbers we use in our country ect,After that we then went on to learning about the different treatments for timber that we use for our builds.H1.2,H3.1,H3.2,H.4 and H.5The higher the the number the more protected the timber is against Boreing,Fungus,Dampness basically rotting.H5 are used for piles and fencing along with H4.

H1.2 is mostly used for framing,It is protected from the weather above ground,But with an exposure to moisture.It is protected from borer and fungal decay.

H3.1 and H3.2 is exposed to weathering above ground level with periodic wetting,basically protected against Fungi and borers.
Also used for decks and external beams as long as it does not touch the ground.

H4 is exposed to the weather in the ground or in fresh water,ground contact or conditions of severe weathering,mostly used for fence posts and landscaping timbers.

H5 The highest treated timber,Used for ground contact.To be used for piles posts for decks.

We were given a small chart with a summary as to what each treatment does.Once we had been in the class for an hour we moved back to the EShed where we done our first Wall assessment.After this Me and Tom set out to correct yet another few walls,The first one have the lintel put in the wrong way and the second being that they used 90x45 for a lintel over a wide space when 6x2 was ment to have been used,plus gal nails were not used for the lintel.I cut the 6x2 up to the correct length,1670mm then used galv nails,nailed in at 300mm centers,4 nails for each 300mm row.Each row to be shot in different directions.This is done so the lintel has no way of coming apart at all.

After this I then finished nailling in the Second top plates,After the walls were plumb,A few others went around and used the plumb bob,We then braced From the inside and removed the outside braces as they will be an obstacle later on in the build.
