Hi, I brake the lids of the septic tank. Impossible to find the same model at Homework, Homepro or Thaiwatsadu. I thought to use a thick tile or a rectangle concrete paving slabs for walking in the garden, but i can't find any big enough. I need 55 cm x 55 cm. I also thought about using a steel plate cut, but it's very expensive. Do you have any idea ?

 

Cheers

What about thick plywood, can treat it with wood preserver?

You have to search around for manhole lock

Just a FWIW, you would need a good exterior plywood for it to have any chance of it surviving soak it in Chandrite at least 2 or 3 times find a good exterior paint then it will probably last a year or 2.

 

However you could use short concrete planks, neither the concrete nor the wood will do a very good job of sealing the hole

In the night I always look for nasty python in toilet before sit down. Had a spider run out close to my balls from under seat once at a rented bungalow. Scared the bull pie out of me

And every construction shop have concrete rings with lock, so you improvise making a new top finish around your existing opening

Tiles of 60x60 and 80x80 available everywhere for less than 200 baht a piece.

 

I have 2 water storage tanks covered with it, after the concrete lid started crumbling

26 different sizes...

2100 baht is pure rip off.

 

Bit searching on Shopee and you find them at less than 500 baht

Easy-peasy!

 

Stop by the local concrete dealer, one on the highway selling concrete pipes and cinderblocks.

 

You can buy 1m round concrete pipe junctions, and can also separately purchase the concrete lids.

 

That will cover the septic, won't blow away, and will support your weight if you walk on it.

 

Should cost you no more than 100 baht.

Something like this:

 

You can cement a concrete ring on top of the existing concrete and use a round concrete cover (as in the above picture ) but without the holes. This is how I repaired ours.
