Hi,
I have dug the trench for my foundations for my extension. I need to calculate the concrete top pour level. Im going 3 concrete block courses below DPC.... so pour the concrete to 675 below DPC level?.
The DPC on the house is in 20mm of mortar. Should I measure down from the DPC mid way of the 20mm to 675mm? Or do I measure from the top of the brick below the DPC?
Im assuming the DPC normally is in 10mm of mortar? Extension is being rendered so matching doesn't matter...
Thanks...
