Our 2.5 Inch Track Detail
When you buy Mikey Block, we encourage you to
purchase an amount of 2.5 inch steel track equal
to the linear footage of your walls times 3. This
isn't absolutely necessary, but we think it's a
great facilitator for installation, as it serves
so many useful functions. The first function is
achieved by attaching the first third of the track
to your slab or stem wall using 1/4" x 1" nail drive
anchors or ramsets. You lay it out so the inside
panel of the first course of block drops right into
this track. The purpose is two-fold. First, it allows
you to lay out your bottom course as straight as
a string and second, it provides an attachment detail
for drywall and baseboard down at the floor. Note:
the OSB provides continuous horizontal attachment
at the top of each course, but there is no OSB at
the bottom of the wall.
The track's next function is as an aid for aligning
the walls. Leveling and plumbing is normally done
after stacking three or four courses as follows:
- Place the 2.5” track over both panels of
the top course, staggering them slightly from
one side to the other so their ends don’t line
- Plumb the corners (leads).
- Sight between the leads and adjust alignment
of the walls as necessary.
- Spot glue the blocks together on both sides
at one-foot intervals.
- Gently remove the track, stow it out of
harms way and continue stacking the walls.
Two more track functions come into play at grout
time. Walls are typically grouted in two or three
lifts, so you use the track for the intermediate
lifts and for the last lift. Here's why:
- As before, it serves as a tool to align
the wall prior to grouting.
- It keeps grout out of the top OSB groove
(FYI using OSB for this is not a good idea because
it turns to oatmeal in the presence of water,
of which wet concrete has much).
- When left in place after the final grout
pour, it provides an attachment detail for the
very top of the wall (where there is no OSB).
