Hi,
For the last 32 years living here I've been fed up with water entering the workshop (garage) being blown under the door; a few days ago I finally got to this problem and have now hopefully sorted it once and for all.
Whilst at "The Metal Store" I added a length of 2" x 1/4" x 96" aluminium to the order asking for this to be cut in half allowing it to be brought home in our car. The fun really started when I tried attaching this to the concrete floor; my intention was to drill and countersink mounting holes in the aluminium then screw it to the concrete with special masonry screws. All went well at first; I drilled and countersunk the aluminium then with the doors closed aligned the first length and marked its position; with a small dia. masonry drill bit I drilled through leaving marks on the floor; the screws needed 6mm holes so out with my big Titan SDS drill and in percussion mode tried drilling the holes in the concrete; the drill refused to go into percussion mode merely revolving only so in disgust the big drill was laid aside and out now with my old but trusty Bosch hammer drill and at last I had the first line of holes drilled.
I started to use my 18V cordless Makita drill/driver to run the screws home but the drill battery died on me. Picking up the SDS drill I ran the first screw until it locked solid half way home; the second screw promptly snapped in half; out with the first screw and re-drill at 7mm; at last the screws went home; before positioning the aluminium I ran three heavy beads of clear silicone sealant to allow a water tight joint. The second length of aluminium was secured using old fashioned plastic wall plugs and countersunk stainless wood screws; I'd had enough of the special concrete screws messing me around.
As usual the rain is still coming down today but now the inside of the workshop remains dry; another job ticked off but not before time.
Kind regards, Colin.
Aluminium screwed and seal to the concrete; any future problems I'll replace the aluminium with stainless steel. It's not wet inside it's just the sealant that's showing. I'm constantly fighting our dire weather.
