|Compacted ground ready for landscaping fabric|
Then a cement truck loaded with gravel arrived. Instead of manually carrying all the gravel uphill, it would be delivered "by air" to the correct location. Why did we not think of this before but relied on raw manpower and wheelbarrows before?

So the next part was easy. Pekka could just watch 15 tons of gravel (0 - 32 mm in size) moving 20 meters up hill to our backyard, slowly covering the landscaping fabric.

Then the gravel was evenly spread around the 45 m2 terrace area with shovel and then compacted carefully with water and compactor to finish the first gravel layer.

Next the entire area was covered with 50 mm Finnfoam thermal insulation to minimise the impact of ground frost. Gaps between the panels and walls were filled with expandable urethane foam.

The picture below shows the slight inclination of the terrace on the border of foam and wall. The exact inclination will be adjusted with the following layers to match the recommendations.

The following morning, at 6.30 am (way before Pekka's morning coffee), the gravel truck returned and shot another 17 tons of gravel (0 - 16 mm in size) on top of the insulated terrace.

The piles look huge first, but both times the amount was just perfect (thanks for the providers calculator!). Fortunately Pekka got some help from Sofi, who was quite keen on assisting with her own shovel.
After 2.5 days of intense teamwork, we were finally at the point we originally planned to have achieved more than a week ago.
|Terrace foundation - ready!|
Without Juha's laser Pekka had to rely on a traditional string line method to determine the right ground level. The top gravel layer is now compacted and levelled correctly with an inclination of approximately 2 cm per each meter away from the building. The border stones (which were actually recycled stones from Project Underground) have also been laid to determine the area and support the structure.

Despite this being perhaps the project with most adversities, everything is now finally ready for stone dust and slates. But those will need to wait a bit. We need a small vacation first. All inclusive with relatives.
