Product Overview

The Tsunami Seal Garage Door Threshold Seal mounts to your garage floor creating the perfect seal between your door and your garage floor. The Garage Door Threshold Seal creates a tight seal for your garage door which will keep leaves, dirt, water and snow from being blown under the garage door by the wind. Also, if you have a sloped driveway or an uneven garage floor and water is seeping under your garage door, the door seal adds a 1/2 in. tall barrier to the garage floor. The door seal will also help keep out unwanted insects and snakes. By creating a better seal, your garage will stay warmer during the winter and cooler during the summer, helping to keep your energy cost down. The door seal works great with all types of garage doors including roll up doors, hinged wood doors and walk through doors. The one piece strip is permanently secured to the garage floor with the included Liquid Nails Polyurethane Adhesive. Each kit includes the one piece Threshold Seal, two cartridges of Liquid Nails Ultra DutyTM Poly-Adhesive and a metal caulking gun and color installation instructions. Comes with a lifetime warranty.

It appears to be vinyl. It is not rigid, but firm like rubber. Driving over it in a car leaves no flat spots.

I don't think so, because the strip is flat and kind of wide, it has a grove into which the door's bottom seal will rest when in the closed position. It is designed to provide a built-up area behind the door that shunts the water away from running under the door's bottom seal. Nevertheless, a portion of the Tsunami Seal extends forward to the exterior (i.e. driveway side) of the garage door. Because of this, the surface for it needs to be relatively smooth.

Does this product prevent mice and rats from coming into the garage, or can rodents chew through it?

A rat can chew through anything. I would say no. I cut it with a miter saw easily.

I would think it will work, I am having the same problem and I hope that with the ridge on the seal it will keep water from getting under the door allowing to freeze

Can we use this inside the garage to prevent water from traveling across the floor?

Its about 3/4" thick, so it thats all the deeper the water is it should work. You need to use the polyurethane adhesive to bond it to the floor and then you would not be able to easily remove it.

Will the epoxy hold on a slurry-coated asphalt garage floor?

The adhesive is polyurethane and it seems to stick to just about anything. As long as the coating is tight i would think it would stick to it

Tip for installation of 20’ Garage Door Thresholds
It was a little tricky to keep the threshold straight while the glue was drying, but overall it looks nice and is keeping water from the laneway out of my garage whenever we have snow melting out there. If I did it again, I’d use fence boards to align it while glueing it down.

Installed about a month ago, finally got rain out of the southeast that usually comes under the doors. So far it's dry, I thought about making a little dam at the ends, but so far it's not required. Also bought the 20' kit to do two 9' doors and saved a few bucks. Installation tip: I laid it out on my black top driveway on a sunny day to relax the curl from being coiled for packaging.

Really seals the bottom of the door. I powerwashed the floor before gluing the seal down which made things real easy. The instructions call for wiping the area down with alcohol, power washing was much more effective. The only problem was i used a little too much adhesive and have a glue mark on the outside of the door. It does the job as far as giving you a watertight seal
