SEAL / FILL / FIX / A CRACK IN CONCRETE DRIVEWAYS

This video explains the causes of cracks in concrete driveways.
There are several types of cracks in concrete: Structural cracks, and shrinkage cracks.
Structural concrete cracks should be sealed to prevent water from penetrating through the slabs. When water penetrates into the soil that supports the concrete, soil may settle, creating a bigger crack over time.

Sealing a crack is not fixing a crack as most people think. Sealing a crack is the application of sealant (caulk) into the crack. The purpose of sealant or caulk in a crack is to just stop water leakage under the slabs and stop vegetation from growing in the crack.

Sealing a crack is inexpensive and must be done to slow down the deterioration of concrete. Remember, your driveway should never have open gaps. Expansion joints should be replaced, cracks should be sealed or fixed and your front yard must have grass.

Why replace concrete when you can fix it!

Collect the dust made from grinding the cracks to sprinkle back on top to match the color.

Thank you for this video! The sand is genius to help it not stand out as much! We are in the middle of selling our home and inspector wanted us to do this, but it didn’t look too good after, but the sand helps to hide that stark grey sealant.

Can you add regular sand to the sika crack fix that is meant for sloping driveways, as well as the self leveling Sika sealant which you used in this video? I would assume yes, because they are both polyurethane concrete sealants.

[glorioskey]

what is meant by sealant is less than its width at 1:42?
