Concrete underground catchment and termites

[Kelena]

Still, baby -- the catchment is under the patio. The patio is in a puka, or a huge natural hole in the lava. So is the house. Imagine a lava, and then imagine a large depression in that lava big enough to put a house and patio in. That's what they did here. And so while strictly speaking the catchment and pool appear to be below ground, they are not. They are just below the grade of the rest of the land. Concrete doesn't attract termites that I know of. In fact, the catchment doesn't attract much. It is fully enclosed. To access it, you lift an impossibly heavy lid on the patio. Then you look in. You see your face. Clouds behind. You close it vowing never to look in their again unless you have to.

Catchment's built in this way are probably only practical if there is some sort of large natural depression in the land. Otherwise you will have to blast a catchment size hole in your yard.

Or, perhaps Pele will blast those out for us! She does appear to be a little steamy right now. I know. I looked right at her.

Wow.
