Dear forum readers,
I am looking for a fastening tip for the substructure of a terrace. I want to build a terrace (approx. 5 x 3 m, wooden decking 25 mm on support beams 45x70 both Bangirai) in front of our terrace door (approx. 40 cm above ground). The substructure consists of holes 35x35 approx. 30 deep, in them a sidewalk slab 30x30, on top a drainage pipe DN150 standing up to approx. 25 cm above ground, filled with concrete, embedded post shoe. Does anyone know suitable post shoes for the beams only 45 mm wide and preferably not higher than 60 mm? Or should one first put a "substrate wood" in the post shoe and place the support beams on it, since I only find post shoes with width 71/61 mm and height 100 mm? Or does anyone have another suitable idea? L-post shoes are usually too high (80 mm).
There will certainly be many foundations, but because of the access, I cannot bring in an excavator and also cannot remove the terrain (sandy soil) and completely fill with gravel etc. An advantage is also that I can build the foundations gradually alongside. The problem is just finding the right post shoes. Does the wooden beam have to sit tight on the base in the post shoe or is it sufficient if it is held by the side screws?
The terrain under the terrace will be leveled with a slope of 5-10% away from the house and covered and weighed down with fleece/foil.
Many thanks for tips
