Customer Reviews for Trim-A-Slab 1/2 in. x 50 ft. Concrete Expansion Joint Replacement in Grey

I highly recommend this product! It's worth the money and it's a HIGH quality product. Application is simple and it add value to to property. NO WEEDS is coming through after Trip A Slab is installed!

I bought this expansion joint replacement product rather than buying backer rod and self leveling sealant. Once I cleaned out the gaps, installing the trim-a-slab took only minutes. So much easier than using the sealant. It has been more than a month in the middle of summer and no weeds. No worries of the sealant pulling free from the concrete. If it pushes out due to freeze-thaw cycles, just push it back in.

Installed it in 15 mins. Too early to give durability review. But it looks sturdy and snugged fit. Hammered it in on edges.

worked and fitted better then I expected.

Expansion wooden joint by my garage has rotten badly. I came across this product while browsing the Internet for info on how to replace the wooden joint. I was skeptical at first since it's not cheap in compare to pressure treated wood. I am so happy that I've made a right choice. The product is super easy to install and look great. Just wonder how long it would last and how it is going to behave in winter.

Does a nice job. Easy to install. Looks good. As advertised. Met my expectations.

Very happy so far with our purchase, I am attaching pics from installation a few weeks ago. As all of our original felt expansion joint deteriorated we needed to do something before winter. So first dug out all the old, then used 1/2” x 4 foam expansion joint, trimmed it and topped it off with this product for a very nice finished look. A little more costly but hoping it will be worth it in the long run. Time will tell how it will hold up in our Illinois winters. We try to buy as many American made products as we can and support our American families. Thank you!

This worked perfectly to fill the gaps on my 16 & 8 foot wide garage doors. It goes in with a dead blow hammer & stays in place allowing no water into the gap. Looks great too!

Excellent product & decent price ($1.50 per foot). Easy to install. Very resilient to the elements & cleans very easily. I managed to fill varying gaps from 3/4" to 1/4" with this roll. 1/4" was very tight and took a lot of slow & easy patience. 3/4" was nearly too big but stayed snug. The majority of my area was 5/8" (see pic)

Easy to work with, cuts easily, functions as advertised. 3 year old installed product holding up well

This Trim-A-Slab product is the best ever to seal gaps between concrete slabs. I first purchased the sample kit containing 6-7 different sizes, tested each sample until I found the right width (1 inch wide), then purchased the 25 foot roll. I used a rubber mallet to lightly pound the joint down firmly into the crack and it looks fantastic. What is so good about this product is that, while it is easy to insert into the crack, the construction of the material makes it difficult to pull it back up - and that is exactly what one would want.

If you have the black felt expansion joint that is disappearing, this is the answer. Blends nice with existing concrete. Very flexible and is easy to install. I installed a double driveway and entrance sidewalk in no time. I don’t mind paying for a long term repair.

Works great and was easy to push into a .75 wide space. Much nicer look than any caulk. I would use this product again.

Fit perfect and looks good too

Excellent product, a bit pricey but worth it!!

It works great easy to install a and looks better than wood

Expensive but easy to install and it looks great.

Used it before and will use it again. Great stuff!

This was so easy to measure, cut & install for a pool deck. Loppers make the first cut easier. But you can also do that & trim it with only prunning sheers & a mallet to pound it down. It's flexible & if you make a mistake just pull it out. Provides perfect coverage. No gaps. No messy & difficult caulk ever again. Great customer service. Get the sample pack first. Definitely worth the money.

Great product Easy to use and install Looks great

Trim-a-slab makes it really easy to fill expansion gaps, used it at a number of houses
