We are going install concrete slab subsequent to my house foundation. Should I own the foundation anchored to it?
Answers: If this is an established house, (at least 5 years old) most of the settling around the foundation is done. Anchoring to the foundation is flexible. If it is a newer home, anchoring to the foundation is recommended.
Many times (over time) the slab will drop next to the house, cause by soil compaction, excessive water run bad. Anchoring it ti the foundation is simple and insures it will stay where you placed it.
There shouldn't be any cause to "anchor" the new concrete to the dated. You should install expansion joint between the investigational pad and the existing slab.
New concrete as it cures will expand and contract more than the aged concrete. Anchoring it might make it crack.
YES,big word very soon.If your roof line is going to clash existing
ridge line, later yes. Also if your wall or window rank is to
match. If within is a possible way,drill holes3/4" around contained by old foundation give or take a few -6-" deep...Buy 1/2"re-bar -1'-long an put within
holes.Put holes about -18"-apart the Leigh of Foundation,an
this should support your solidity. Reason Holes are 3/4" is to allow some concrete in holes.
Also,Make sure you draw from a good Bond at Jointing of both
slabs of Concrete. You don,t want Water surrounded by there from beneath
slab ,use seal int when concrete cures out.
Note:::be sure to verbs Level off outmoded slab an you MIT want a Gravel base underneath New Slab,to help beside Drainage ....
Good Luck///
It would depend on what your going to do with the slab. If the slab is subdivision of an expansion of your house, then you would want to anchor the bright slab to the old slab. This path you would minimize any differential settlement between the slabs which might ultimately effect the connection of the alien room to the existing house.
If the new slab is articulate a seperate patio, later typically youo would place expansion joint textile between the two slabs and let the strange slab float next to the house.
Good answers so far but a couple clarifications might relieve us help you better:
1.) What is the purpose of the slab?
2.) Where are you located geographically (i.e. is frost a concern...)?
Thanks for the update... With that information I wouldn't verbs about anchoring it to your existing foundation. Since you are using a contractor, I would follow his proposal. Make sure you have positive drainage away from your house (slab slopes away). An expansion collective is not a bad conception...in certainty, like others, I would recommend that also. There are other materials out near besides wood.
Enjoy your new court!
