Concrete the Tank Pump Pad

1700 × 1300

Road base and that’s should be all

pad size change to be 1600x1200
that's usable area of 1200 x 1000

at 70mm thick, this is 16 bags of concrete.

to block the out side would take 10 blocks per layer at 4 layers ~44 blocks if i use the half width.

So the only changes from before are the number of blocks, and the size of blocks. and 1x 6m 30x75 for the frame.

1400x1200 x 100mm thick - about 15 bags
7x 190x190x390 besser blocks per layer.
28 besser blocks total.

4 bags of standard mortar
trowel
50mm pipe + 4x 45s
5 bags of concrete to fill corners
roadbase to go underneath

going to have a few pieces of pipe going through the concrete, for mains power, in water, out water. Maybe one for the sump power?
