I am building a basement wall with lecablocks that will connect to an existing sill supporting the upper floor (see the pictures below). I have a couple of questions about this that I hope you can help me with.
1) How do I make the connection between the lecablocks and the sill? There will be a gap of about 2-3 cm when the last two rows are laid. I've been advised to either wedge or apply mortar. If wedging is the solution, what types of wedges should I use, and what do I fill the gap around the wedges with?
2) Do you have any tips on how I can secure the sill to the blocks so that the upper floor is anchored in place?
I solved it all by slightly lifting the house with jacks (hydraulic jacks from Biltema) in the same hole where the support was to insert extra sill between the existing sill and the brick wall.
I prepared this extended sill by gluing the sill paper in advance and then cut out holes for the jacks before placing it and lowering the house again.
