Hello.
We will open a part of our load-bearing wall, approximately 5100mm.
Part of the opening is already opened and relieved with a beam constructed from studs, this beam is 260x65mm.
The foundation is a bed of crushed stone, a footing cast of about 500mm x 170mm on which a wall has been built that in turn is approximately 190mm wide.
Question 1: Does anyone know if the foundation needs to be reinforced, and if so, how is this usually done?
Question 2: If one chooses to build a custom support without shores, how should it be constructed?
Grateful for answers.
