Exposed Aggregate Decking Over a Septic System

[dplte]

I'm new to this board and have a question that I can't seem to find anything on after a few quick searches, so sorry if it's a redundant subject.

We're putting in a pool and large deck area. The exposed aggregate concrete patio deck will go over part of the septic tank and the access cover. Obviously we will install a sleave to gain access, but I'm concerned about a cover. I don't want to install this beautiful deck and have a big ugly cover. Has anyone run into this? Any solutions?

Is there a way to make an exposed aggregate cover to match the rest of the deck? I will go back to our "deck guy" next week to discuss this, but I'm wondering if there were others that did something similar so I can reference the ideas in my conversations with him.

Thanks!

Just keep in mind a septic system will not last forever. In my area they last 15-20 years. If you have a problem with your system you may have to remove decking to replace a tank or leech field repairs. I haven't heard of a deck being put over a septic tank. Is your pool close to the septic system? I would try to find an alternate location for the deck.

It's really just a large deck area. Instead of doing a separate deck area out of composite decking or patio blocks, we thought it would look far nicer keeping it in the same decking material.

I hear what you're saying, and it's a good point and something we need to make sure we realize going in...Thanks!

You probably shouldn't deck over the septic field, but decking over the tank itself shouldn't be a problem. Work out a joint pattern in the deck so that a small portion over the tank lid can be lifted out. That portion of the deck should be specially constructed with extra reinforcing and lift spots embedded. Our septic tank lid has a hole in it, so some sort of venting may be standard practice, but I don't know that for certain.

This product is probably too small for your application but it should give your concrete guy the idea: Pour-A-Lid.

Outstanding, thanks for the info!
