In late April we had a really wet snow storm and the resulting melt swelled the subsoil under the center of the garage door - had to use a grinder to take it down about 3/8" but still got water under the door at both ends. It was time for a threshold.
I looked at one from Harbor Freight but didn't like the quality. The Tsumani Seal (tm) looked like the type I wanted but several posts commented that it was about 2" short on some 16' doors which allowed infiltration.
Then I found a threshold at Ace Hardware: 20' long, same profile as the Tsunami Seal, less expensive ($70) and available locally - plus I had a $5 off coupon.
The kit include two tubes of sealant and one sheet of instructions.
I spent about 30 minutes "dry fitting" and trimming the seal under the door and then layed down duct tape to align the inside - this made it easier to grind down the concrete in the center and skin it at the edges so the adhesive would strick.
I brushed off the dust then placed the threashold down in place. Once in place I duct taped the inside edge to the floor, marked the outer edge with a pencil, flipped it over, used compressed air to blow the dust off the concrete and used a cleaner to wipe the bottom of the threshold.
I applied the three beads of adhesive per instructions, flipped the threshold over (it remained perfectly in place) then applied duct tape along the outer edge and closed the door. The threshold stayed in place with no movement.
On que, a few hours after putting down the outer duct tape, it rained but the duct tape kept the water from the uncured adhesive. The next day I removed the tape and again it rained HARD in the afternoon. Not a drop of water infiltrated in where normally I would have had two nice sized puddles six feet into the garage.
So far it looks like a good product. Only minor complaint is the sealant/adhesive is thick and very difficult to lay down a bead using a hand caulking gun - wish I had an air operated caulker.
