Questions & Answers

Q:With this product, do I need to use a silicone over it?

Answer This Question

A:  No, this is all you need to repair the expansion joints.

    Q:Reviewer suggested ordering a "sample pack" to be sure of width. How do I do that? Also, do you recommend using an expansion joint filler if the replacement does not fill the space, which is 2-1/2" deep and 1" wide?

    Answer This Question

    A:  If you know the space is 1 inch wide, then you need the 1 inch product. The product does fill all 2 1/2 depth, nor does it need to. You'll see how it works when you install it. I have some at my house that I installed around 10 years ago and it is holding up very well.

      Expansion joint in walnut
      This product was the easiest product we ever installed on our long driveway. It took 15 minutes, finish product was a beautiful finish to sealing our driveway and made of lasting rubber material which came in 3 colors. (we’ve spent hours on other products such as foam backers and caulking was a mess, also 4” styrofoam was very difficult to cut to 1/2” and some sections would pop up) I highly recommend

        Fairly easy to install, I used a heat gun to make the job easier.

        I was one of the original testers for this product around 10 years ago, so I can say with authority that it does stand up to the sun and rain. I just purchased this additional product because not all expansion joints in my driveway and sidewalks had rotted out before I installed the first batch of Trim-A-Slab. Now I am replacing the remaining wood expansion joints that have subsequently rotted out. The two most difficult parts of installing this product are to clean out all the wood debris from the expansion joint to the necessary depth, and cut the product to the desired length. It is really tough material. In my opinion, this is the best product for this job.
