Your help please
I need to allow access to lots of pipe and cable within the 700mm high underfloor void of my suspended wooden ground floor. There are sleeper mid-room floor support walls and a full height solid brick load bearing wall in which I will need to insert lintels to support it. The opening will be approx. 900mm wide and 600 high beneath the floor.
I understand it would be risky to just cut out a course of bricks and put the lintels in unsupported while the mortar hardens, two storeys of the house rest on it. But it is difficult getting acrow props in under the floor.
Q? - How can I support that wall while inserting the lintels? They will be 1200 x 65 x 100mm wide.
Q? - Or do I take floorboards away to allow access through for the Acrow to bear on the ground below?
Q? - Will the acrow go down that low, 600mm off the ground?
Your advice please, thanks.
