Can I use Postcrete as concrete?
Consequently, can I use Postcrete for foundations?
Because of the small area, we decided not to mix our own concrete, but to use Postcrete instead. Postecrete is a ready mixed concrete type mixture. It comes in bags that we could just tip into the prepared trench. Unlike normal concrete, you have to make sure that the Postcrete is level before you water it.
Consequently, what can Postcrete be used for?
POSTCRETE may be used for fixing decking posts, rotary washing lines and small/medium sized gateposts (less than 1.0m width gate). POSTCRETE may not be used for general concreting, screeds, mortar, grout or render. If a specified compressive strength is required, POSTCRETE should not be used.
Concrete is the most secure material for setting fence posts, especially if you have sandy soil. Gravel may be okay with dense, clay-heavy soil, but in looser soil, concrete is the only thing that will truly keep your fence posts stuck in place.
