Hello dear Bau-Forum community,
we, my wife and I, have an end-terrace house on the side of which facing the garden we want to build a wooden terrace, we have a side exit and this is just perfect for it.
But we have a big problem, in the area beneath the planned terrace there are utility lines (electricity + water) at a depth of 80 cm. Our soil is former arable land (clay and loam mixture) which is heavily compacted and contains a high amount of stones, from pebbles up to a still manageable block.
What kind of foundation should we plan for it, we have read everything about it, from directly on the ground, driven ground sleeves, gravel foundation at only 40 cm up to full 80 cm as point or strip foundation, because nothing else is frost-proof, but there the lines might be in the way!
My last thought on that was 40 cm - 60 cm and placing the whole thing on screwable spacers, then I could possibly just compensate for frost-shifted unevenness again.
But what is sensible and safest in our situation? Are there any experiences on this?
My uncertainty is great and once it’s done there is no going back without consequential costs!
What can I and should I do?
