门口地砖向下凹陷

二月森林

看房子中，所有都满意，就是正门的地砖凹了一块下去。这个问题严重吗?是排水问题吗?

通常都是汽车压的吧。是车库进出位置吗？
应该不严重，大不了自己翻起来重新铺。我后院自己铺的，绝对比builder牢靠。

是不是大问题，做house inspection的时候问问就行

从风水来说，房子前面可一定要平整

可能需要將就舊的地磚拿起來，加上BLUE METAL，重新鋪平壓實，再鋪上地磚。

等於是再重鋪一次。

Construction aggregate, or simply "aggregate", is a broad category of coarse particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined material in the world. Aggregates are a component of composite materials such as concrete and asphalt concrete; the aggregate serves as reinforcement to add strength to the overall composite material. Due to the relatively high hydraulic conductivity value as compared to most soils, aggregates are widely used in drainage applications such as foundation and French drains, septic drain fields, retaining wall drains, and road side edge drains. Aggregates are also used as base material under foundations, roads, and railroads. In other words, aggregates are used as a stable foundation or road/rail base with predictable, uniform properties (e.g. to help prevent differential settling under the road or building), or as a low-cost extender that binds with more expensive cement or asphalt to form concrete.

10 mm graded crushed rock or aggregate, for use in concrete. Called "blue metal" in Australia. 10毫米大小的石头子儿。
