How to Fix Excess Water on a Driveway Apron

Use a diamond-tipped hammer drill to make holes in the apron measuring 2 inches in diameter. The holes should be spaced 6 inches apart down the center from the highest point of the apron to the lowest. The holes must drill through the thickness of the slab and into the dirt or gravel foundation beneath.

Thread a 2-inch hose through the first hole in the highest part of the apron. Feed the hose through the hole until you feel resistance. Screw the remaining end of the hose to a pump for mudjacking.

Mix foundation filler in a wheelbarrow with a metal hoe. Dump one part cement, two parts sand and small amounts of water to make a thick, spreadable consistency. Use a shovel to add the mix into the mudjacking machine.

Adjust the setting on the mudjacking machine to pump at 10 PSI. Turn the machine on and pump filler into the hole until the section rises to its original height.

Move the hose to the next hole, thread it through and pump filler until the apron rises to the correct level. Continue to raise each section of the apron by pumping filler into the respective holes until the entire apron returns to its original height.

Use a stiff mortar mixture to fill the holes you drilled through the driveway apron. Smooth the surface with a trowel so its level with the rest of the apron.
