Suitable for both vertical and horizontal joints, Sikaflex 1A is an ideal choice for sealing windows, door frames, roofing details, and other construction joints.

Review: Awesome sealer for concrete and gap filler - This product worked great as a gap sealer between the concrete slab and bottom plate of our wood framed workshop. It is very rubbery when cured so it won't crack or shrink, very similar to silicone but with a rubbery feel to it. I have also used it as a sealer between the window flange and framing of a window opening in new construction applications. I think you can seal gaps up to 3/4" but that's gonn use a lot of material for a gap that large. I reccomend using appropriate size backer rod, then top coat with this product. -MLC Remodeling
Review: Durable and Stays Bonded - Put in a channel drain and sealed to side walk with this product. Adheres nicely and easy to work with and dries fairly quickly. Good concrete joint sealer.

After cleaning the expansion joint between the garage slab and driveway, I followed directions to ensure uniform depth with foam. Application was easy and required some smoothing, it turned out great. I highly recommend this product.
