Rubble Foundation to Sill Plate Connection

Rubble Foundation to Sill Plate Connection

Rubble Foundation to Sill Plate Connection

(OP)
Rehab to a house with a rubble foundation.  Old sill plate sat on wall.   To meet new requirements, must anchor sill plate to rubble foundation wall.  Any ideas? Thanks

RE: Rubble Foundation to Sill Plate Connection

Not exactly sure what you mean by "rubble".  If it is just stacked stone - just about any anchor will not be worth a darn unless you take it all the way to the ground..

It is stone with a minimal amount of mortar.  Basically a dry stack.  I figured that was the case.  My thoughts were to attach a flat bar down about four feet and attach horizontally.  Weight of stone would be resistance.  Would have to drill into a large stone.

RE: Rubble Foundation to Sill Plate Connection

You can drill, let's say, 1 1/2" boreholes down 8 feet, fill them with cement cartridges and install 5/8" rebar threaded in one end, then you lock off this bolt with a torque wrench against a flat bar like the one you are thinking of employing. A 25 lb rotary hammer will do the job. Regards.

RE: Rubble Foundation to Sill Plate Connection

You are not in Kansas anymore!!!  Something along crcivil ideas makes sense.  You could use heli-coils or some type of earth anchor.

And good luck drilling into stacked stone - unless it is lousy limestone
