What to Do With Holes in Brick Walkways?

Cement

• Go to the local hardware or home improvement store and buy a bag or two of cement. The store may rent you a cement mixer or have a small one for sale. Because you are making small amounts for filler it would not be impractical to mix the cement in a paint or coffee can or larger container by hand. Add water to the dry mix and blend until it is of a good texture for your purpose. Take a putty knife and fill the cracks with the cement. Even off the edges to make it smooth. Clean any extra cement from the surface of the brick. This is the surest way to fill the gaps but it does have a visual downside.

Gravel and sand

• A fine mix of sand and gravel can fill the cracks adequately. pour the sand and gravel over the area and sweep up the extra amount after the hole is filled. The gravel and sand will settle into the cracks and provide a more flexible buffer than the cement mix. In extreme heat and cold the cement can crack but the sand and gravel mixture is not effected.

Mud

• Thick mud can temporarily fill the cracks but is not a permanent solution to the problem. Mud has some of the same qualities as cement in that it will fill the spaces and then harden. Unlike cement it will wash away in a few good rain storms. It is better than sand alone or just gravel.

Asphalt

• Rubberized asphalt crack filler is a black tar-like substance that is very weather resistant and comes in cold weather and hot weather formulas. It can extend the life of your walkway or road surface by giving the least amount of friction between the bricks in extreme weather. It doesn't crack like cement and doesn't shift and settle like gravel and sand.
