這個不是french drain？這個公司是這麽說的

 In order to keep it dry 52’ of a French drain is needed with a sump pump. The cost to keep that basement dry is $4,675. Let me know if you have any questions. That basement has been flooding out for a long time with the condition of the floor. It will keep it bone dry with that proposal.

• 別管它是與不是，隻要能排幹水就行。整體不算壞，這房子水泥牆看著沒問題。地麵狀況不太好，但隻要不積水不下沉，就不用擔心。 -守月- ♀ (69 bytes) () 02/10/2024 postreply 20:42:06

• 我專門看了一個視頻，French Drain 是把yard裏的水導出去的。 就是說把你地下室牆外麵的水給導走。 -NBA_19- ♂ (214 bytes) () 02/10/2024 postreply 21:20:27

• 地下室的這種往往也被叫做French drain，都是用Henry French發明的這種水往低處流的 -W2_2023- ♂ (29 bytes) () 02/11/2024 postreply 01:58:05
