介回答太搞了！

这么技术性的问题，我哪儿懂。再说地基沉降和土地的地质也有关系，怎么会有一个定值呢？如果你家房子是二三十年的，那沉降应该结束了吧，如果就是两年的新房，也许就没有。

这个说法是对的，确实跟地质状况和房子本身有关。

let me ask my contractor and see what he has to say about the issue. the concrete stairs is actually hallow and it is bolted to the house. we can already see a gap between the stairs and the garage wall on the side, and underneath the stairs between the ground.



our design is to lay bricks directly onto existing concrete stais and also to build new stairs on the side to step down to a patio. and we are also widening the steps.

How do you know? Our step was hollow underneath too but it was poured with the fundation.

because there is a big gap between the concrete base and the ground (those big cheap square blocks from the builder). it looks as if the stair is hanging in the air (that's why the contractor said he is sure it is bolted to the house). otherwise, wouldn't have the whole concrete stairs sinked and sat the ground?

i forgot to mention that the concrete stairs have 3 steps. they look identical to those in the back yard.
