FIXING TO CONCRETE SLAB
1.0 COLUMN SPACING
Determine the location of the concrete slab. Figure
1 and TABLE 1 COLUMN SPACING indicate the
location of all columns. The outside edge of your
slab shall be no less than 70mm from the outside
face of the columns.

2.0 SLAB
Two base plate styles are available and depend on
the type of concrete slab being laid. If you have
chosen to incorporate integrated footings with
your slab, a two hole base plate will have been
welded to the base of your columns, if your slab is
not going to integrate footings four hole base
plates will have been supplied.
Footings shall have a diameter of either 450mm or
that as specified in Table 2.2 (“Stratco Gable
Homeshed, Framework”), whichever is greater, with
the depth as specified in the same table. Mark out
and dig footing holes at the locations indicated in
STEP 1.0 of the “Framework” instructions. Pour the
concrete footings and score the top before pouring
the slab. The slab must be at least 100mm deep.
Remember to include footings for any
internal roller door columns on Type 1 sheds (6.2 &
6.9m wide sheds only). Footings are not required
for centre roller door columns on Type 2 sheds but
Concrete Slab with Integrated Footings:
Note:
These pages are designed to give you the basic assembly techniques to fix your Stratco Gable Homeshed
onto a concrete slab. Please use this page in conjunction with the main set of instructions supplied,
“Stratco Gable Homeshed, Framework” and the appropriate door installation instructions.

Once the slab has set,
mark out column
locations. Follow
STEPS 3.0 to 6.0 from
the “Framework”
instructions. Also refer
to STEP 4.0 below if PA
door/s are being
installed.
Stand the completed
wall frame in the
positions marked and
temporarily brace as
illustrated in Figure 2
STANDING WALL.
Repeat for opposite
side wall. Do not
remove bracing until
column base plates are
fixed to the concrete.

Important Note: It may be necessary to pre-drill some
or all of the concrete anchor holes before columns are
braced in position. If columns interfere with the drill
and do not allow clearance through base plate holes,
mark and pre-drill required holes to size and depth
specified in STEP 5.0.
If your Gable Homeshed includes PA door/s, door
mullions will need to be cut to sit flush with the top of
the concrete slab. Mullions are to be fixed to the slab
using a 45mm angle bracket with an M10x20 hex head
bolt and M6.0 x 40 masonry anchor as shown in Figure
3 PA DOOR MULLION. All other details are as specified
in the “Framework” instructions.

5.0 FIXING TO SLAB
Follow steps 8-16 in the the “Framework” instructions
and check wall alignment.
The size of base plate welded to the base of columns
depends on the shed size and site wind speed.
Measure the thickness and hole diameter of the plates
on your shed to determine the appropriate fixing
requirements:
Each plate is fixed with two M16 threaded rods
embedded a minimum of 150mm below the thickness
of the slab (e.g., 100mm slab thickness will require
minimum 250mm anchor embedment). Drilled hole
shall be 18mm diameter with chemical injection
required to set anchors.
Each plate is fixed with two M20 threaded rods
embedded a minimum of 150mm below the thickness
of the slab (e.g., 100mm slab thickness will require
minimum 250mm anchor embedment). Drilled hole
shall be 24mm diameter with chemical injection
required to set anchors.
Concrete Slab with Integrated Footings:
Type A: 10mm plate thickness, 19mm hole
diameter.
Type B: 12mm plate thickness, 24mm hole
diameter.
slab thickness should be increased to a minimum
120mm for a 300mm square area under the location of
this column. PA door mullions do not require footings.
If you are fixing your Gable Homeshed to a slab without
integrated footings the slab shall be of minimum
120mm thickness, and include a layer of mesh
reinforcement.
In some cases it may be necessary to build the concrete
up to the height of the base plate under a roller door in
the gable end to minimise gaps. This is best assessed
following installation of the door.
For both applications the concrete slab shall have
a minimum compressive strength of 20MPa. The
required slab thickness may need to be greater than
the minimum specified above depending on site
conditions (Stratco assume no liability for slab damage
due to ground movement).
Concrete Slab Only:
Note:
Type C: 16mm plate thickness, 24mm hole
diameter.
Each plate is fixed with two M20 threaded rods
embedded a minimum of 200mm below the thickness
of the slab (e.g.,100mm slab thickness will require
minimum 300mm anchor embedment). Drilled hole
shall be 24mm diameter with chemical injection
required to set anchors.
Refer Figure 4 INTEGRATED FOOTING BASE PLATE
FIXING.
Threaded rod will need to be cut to the required
length.
End columns require the same fixing details as
indicated above. Refer to “Concrete Slab Only”
specification below for fixing requirements of centre
roller door columns on Type 2 sheds.
Refer to manufacturer's specifications for chemical
injection fixing details and setting times.
Notes:

Concrete Slab Only:
For this application base plates are to be fixed with
four M12 chemical capsule anchor studs at 90mm
concrete embedment. End columns will require the
same fixing details. Refer Figure 5 SLAB ONLY BASE
