I have a company that replaces sills in the basement. They have replaced the outer wall with new paper and a new sill that stands on the concrete slab. But the wall in the middle of the house has only been propped up on plastic wedges about cc40cm apart. It previously stood on a sill. But since we are installing a ventilated floor, I assume it should ventilate under this construction.
Does this hold or should they put in more plastic wedges?
They are too thin and weak, feel one and you'll see that each wedge is mostly air and thin plastic walls.
Like these which are designed to withstand pressure..
“Knudsens K-Kloss 6T is a series of blocks that are ideal for propping up heavy objects. K-Kloss 6T is made from HDPE or high-density polyethylene, which can withstand very high pressure. The K-Klosses can be assembled to form a block of desired height, and with a load capacity of 6000 kg, the blocks are very suitable for very heavy objects such as window sections, steel beams, and concrete elements. The different color-coded thicknesses ensure fast and easy precision assembly work.”
