SH-07Fit a ground anchor into the concrete floorBefore drilling the floor, think about what's underneath. Find your stopcock now (usually under the kitchen sink) and check it turns, so you can shut off the water fast if you ever hit a pipe anywhere in the house or garden. Water pipes are unlikely under a shed slab, but if the shed has power or an outside tap nearby, a cable or pipe could run close by — use a cable/pipe detector as a check, but still treat the spot as if something could be there, and if in doubt isolate the circuit at the consumer unit before drilling. Mark the anchor position away from any known cable or pipe run, drill with the masonry bit size stated on the anchor packaging (typically 12-16mm) to the depth given (commonly 80-100mm), clear out the dust, and fit the anchor with resin or expanding bolts. Let it cure fully before loading it with a chain.
