I have an old coal hole underneath the pavement in front of my house. It is structurally sound, but the chute where the coal used to be delivered has not been sealed up. If I look up it, I can see the underside of the paving stone in the pavement.
My problem is rainwater flows around this pavement stone, and down the chute. I'd like to use this coal cellar for mostly-dry storage.
I can only access the chute from below. It is about 16 inches tall, perfectly vertical. How do I go about filling it up? I'd like to (mostly) stop the water ingress, so one of the water-proof "tanking" cements sounds like a good idea, but gravity is against me.
How do I go about cementing/mortaring/grouting/filling....upwards?
