Help,
I'm building a 4m x 3m Koi pond and have alot of thermalite blocks. I know I can't use these above ground.
The construction will be block, foam then fibreglass.
My question is, will the thermalite blocks be strong enough for the walls up to ground level, prob with a 30mm to 40mm concrete back fill. |
