Concrete steps, part 1

For a moment the backyard looked okay. Slate terrace nicely laid, ready for winter to be completed next spring. But then the construction bug bit again, Pekka started playing with his 3D-modeling software and suddenly he was out there again, building stairs.

Earth moving manually 

After digging a big enough hole, Pekka started with some 50 mm Finnfoam thermal insulation to minimise the impact of ground frost. Next, in the spirit of recycling and minimising the amount of concrete needed, he piled the rest of the concrete blocks which used to be our old terrace on top of insulation.

First two stairs

The first two stairs were fine. Approaching the third, Pekka found something we had completely forgotten: a big stump, a remain of a big pine tree which was cut down right after we moved in. Right on the way of the third step. Of the two options, either moving the stairs or getting rid of the stump he chose the latter.

Half cut tree stump

The way was clear again. One step at the time Pekka continued all the way up.

Reinforcing steel wire

Next, he build a steel wire to support the concrete structure.

Building a mold

And finally, a mold for the concrete.


And a few weeks after the bug bite, the stairs were ready for concrete. Even if wishing for a white Christmas, we now crossed fingers for the weather to stay warm as the concrete requires +10C to settle and harden...

Will it hold?
