SlabGasket™ Expansion Joint Replacement Solution (Gray)
SlabGasket™ is designed to replace rotten wood expansion joints in parking lots, driveways, sidewalks, patios, slabs, and pool decks.
SlabGasket™ is used in residential, commercial, and institutional applications.
SlabGasket™ is an extruded, flexible vinyl, the same material used in vinyl shutters, doors, windows, and siding. Immediately effective once installed, no waiting or curing is necessary.
Rapidly installed, blending beautifully with the existing concrete, SlabGasket™ Expansion Joint Replacement also provides a simple and effective weed-growth deterrent and a cure for trip and fall hazards associated with empty expansion joints.
The Regular Height (7/8” width), designed to replace a 1” x 3” or 1” x 4” expansion joint, is the size used by 90% of our customers
To order, select the WIDTH, HEIGHT and the QUANTITY in LINEAR FEET in the spaces below and click ADD TO CART. Repeat for each Color, Width, Height combination that you wish to order.
Available SlabGasket Colors: Gray or Almond
SlabGasket™ is sold "By-The-Foot". QUANTITY = FEET.
How to select the correct size:
Use the width to select the proper fitting SlabGasket size. The height (tall) of each size is provided below only so that you can insure you have sufficient depth. Properly fitted SlabGasket will stay in place as set; SlabGasket does not need to extend the full depth of the expansion joint.

Worked like a charm and so easy to install! It fit perfectly and makes the patio look much better without a gaping crack for frogs and bugs to live in. Price was reasonable too. Cannot wait to try other products to make our patios look new again.
I tried to explain this need to reps at two Home Depots and they had no idea what I was talking about. Thank goodness you all showed up on image search. ... Read Full Review |

Wow. Easy installation and solid fit. Match the width of the gasket with the width of the gap between slabs. To prevent damage use rubber mallet or padding.
Highly recommended. ... Read Full Review |
