I put down a 100mm deep concrete base, 800x800m last week. It is to hold an outdoor boiler. I will be moving the boiler onto the base in the coming days but having pressure washed the base today and some bits to chip out of it I'm worried I've made it too weak...
Is there anything i can do to check strength of base, or should i just put the boiler on and keep an eye for cracks etc...
40kg of cement went into the base along with 50/50 sand gravel. There probably was a bit too much water in though....
But perhaps a boiler weighing id say approx 150kg and being stationary should it be fine??
