DIY Driveway Repair: Cut out the sunken area
Photo 1: Cut out the sunken cobblestone
Slap a diamond blade into your circular saw and ready it to its maximum cutting depth. Then snap a chalk line out from the garage floor to a maximum distance of 24 in. Wear an N95 respirator and safety spectacles and cutting out the old asphalt.
Photo 2: Put in the bottom layer
Pour in a small corporeality of cold patch textile and level it with a square-blade shovel. Tamp down a exam department and measure the depth. The lesser layer should merely be 1/2 in. thick when compacted. Add or remove cold patch material so tamp down the entire starter row.
Photo 3: Build additional layers
Add and compact the common cold patch in i-in. layers until you reach the garage floor. So overfill with an additional 1/2 in. of material and tamp to get a polish surface.
Photo four: Drive over information technology to compact
Cut a piece of plywood slightly wider than the trench. Lay information technology over the patch fabric and embrace it with 2x4s. Then drive over information technology several times with your vehicle until the patch is level with the garage floor.
Common cold patch works only when it's compacted and "keyed" into at least two vertical surfaces. So don't think you can build upward the driveway height by pouring common cold patch on top of the old sunken cobblestone—the patching material will just interruption off in chunks. Instead, yous'll take to cut out the sunken asphalt (Photo i). After it'due south cut, lay a block of wood on the soil at the edge of the driveway, shove a pry bar nether the old cobblestone, and pry against the wood cake. The old asphalt will lift up and suspension off in sections. Remove all the cut asphalt and scrape off any caulking material sticking to the edge of the garage floor.
Side by side, build a starter row of patch textile (Photo 2). Once the starter row is in place and tamped, apply additional patch textile in i-in. layers (Photo three). Resist the temptation to completely fill the surface area and meaty information technology in one fell swoop. You but can't exert enough compaction force with a tamper to properly key information technology into the vertical surfaces—the patch textile will just creep out the sides when you drive on it. In one case your tamped layers are level with the garage floor, add a final topping layer. And then lay down wood scraps and use your vehicle to do a last compaction (Photograph 4). Clean all your tools with mineral spirits and dispose of the rags properly to prevent spontaneous combustion. The instructions say you tin drive over the patch immediately. But tires may still make slight depressions in the asphalt until it'due south fully cured, which takes 30 days. So leave the plywood in place for a few weeks at least.

- Snap a chalk line parallel to the garage door. Make sure information technology's out far enough to include all the settled asphalt. Lay out a row of your paving bricks, starting against the garage floor slab to position the chalk line at a total brick.
- Cutting through the asphalt (it's ordinarily two to iii in. thick) forth the chalk line. Be sure to article of clothing hearing and eye protection.
- Remove the asphalt and dig a 12-in.-deep trench. Angle the wall of the trench slightly nether the remaining asphalt. Rent a plate compactor and run it forth the trench at to the lowest degree four times to meaty the soil. Line the sides and bottom of the trench with landscape material. Information technology's available from landscape suppliers.
- Spread a 2-in. layer of Class V or other compactable gravel, dampen it and run the compactor over it four times. Go along to spread and compact the gravel in 2-in. layers until it'southward 3 in. below the existing driveway.
- Install paver edging forth grass edges and spread a 1-in. layer of coarse sand. Don't meaty information technology.
