 Posted: Mon Mar 02, 2009 6:19 am Post subject: 900 sq slab in rough shape |
    |
|
| i am currently renting a 900 sq ft slab house that has sunk on one side cracking the slab in the middle.it has sunk quite evenly and has made the exterior look like my house was build not on level.i am in a small mining community that is in a boom so buying a fixer is well worth it as the price of housing is way up.my plan is to gut the interior and replace the roof.but what is the best way to go about leveling the home?allso what is required to build a second storey when dealing with a slab?we commonly have - 50 celcius in winter so windows and doors will be done as well and i'll have a 5 month window max to do any ground or cement work. |

braftis,
There are two or three things potentially going on with the slab
under your house and all require careful research on your part.
The sub-soil under the slab has moved which could be due to
poor prep on the part of the builder, expansive soils (water/clay), or because you're in a mining town,
there may be major movement in the ground
beneath the house. I would try to find out how the slabs in the
area were built and if other houses have experienced similar
settlement problems, (frost walls or slab on grade).
If a structural engineer is available in the area, you may
want to pay a consultation fee to gain some insight into
sub-grade soil conditions and general information about
building practices in the area.
Once a reasonable assessment has been made and if it's
determined that simple settlement is the issue,
you should be able to locate a company that specializes in raising concrete slabs,
I think the term is "mudjacking" where concrete is pumped
under the slab under pressure which raises the slab back
into it's original position.
This not a project for the faint of heart but it is possible
providing you do your homework and get the right people involved.
Good luck. |

| Thank you for taking the time to reply.It is just due to poor construction and bad soil. These houses were just "slapped" up during the last boom.I have looked up mudjacking and it seems this is the answer. thanx again. |
