Hole that needs to be filled


I need some advice about filling a hole on my pool deck (see attachment). We're investing in a winter safety blanket for the pool and the guys installing it need to drill holes all around the deck to add these grommets to hold the blanket. The problem is that hole at the head of the pool. They tell me I have to fill it with concrete before they can install the grommets. Previously I filled the hole with GA, but it's certainly not sealed as all around it is hollow as you can see at the edges. I'm just looking for some advice on what I need to do.

I thought about adding those concrete blocks like in this link http://www.homedepot.ca/product/10-inch-standard-concrete-block/981814 , but before I do anything I thought I would check with the experts.

Thanks all.

Since it is all cracked already I would extend that hole up to the pool edge and out to the slab edge. Then drill into each side and install some rebar pegs. Fill with concrete and level to the other slab.

I don't no what GA is. I don't see how a concrete block like the link would be of any use.

Hole that needs to be filled


Thanks, but I'm not looking for major work here. The crack is of no issue since the entire pool deck has cracks. I just need to know what steps I need to take to fill the existing hole with concrete, without making it larger. GA stands for general aggregate, a type of stone (what you see filling the hole).

Mix concrete. Pour in hole. Level and smooth.

those cracks are a major issue. as the current "cracked" slab is what would be holding in the new concrete. then your going to be putting tension on this

the cover doesn't put that much tension on the pegs in the conc UNLESS the conc's really f'd up,,, guessing ' GA ' means graded aggregate BUT that's ONLY a guess

so do as already suggested - fill it w/conc, level it, wait 14 / 21 days, drill hole, insert lead drop-in, attach cover
