The external building profile is used on the outside of wall corners and requires at least three courses of the wall to have already been built and left 24 hours to set. It is the most common profile used amongst builders.
External building profile sizes
The external building profile is available with either a 1.2m (4ft), 1.8m (6ft), 2m (6.5ft) and 2.4m (8ft) length profile pole. When using standard 65mm (2.5″) bricks, the 1.8m mast can lay up to 25 courses and the 2.4m pole will lay up to 30 courses. These are the most readily available sizes.
External building profile attachments
Block builder
The block builder is currently available for use with the external builder’s profile. It attaches onto the profile, allowing the building of internal blocks alongside the building of external brickwork. This is used in house, extension and garage building.
The external profile works the same as before with the string line for the outer wall being run from it. It sits on the external profile and a string line is run off the block builder for the inner wall.
Block builders are made from stainless steel making them corrosion resistant for use outdoors, and fairly lightweight so as not to obstruct or affect the profile.
