How to Fix a Spongy Driveway

If you’re looking for a solid, long-term solution to your spongy driveway problem, then look no further. This blog post on how to fix a spongy driveway is the perfect place to start! There are many ways to fix the problem. Some are easy and quick, while others may require a little more time and effort.

One of the easiest is by using sand and gravel. Simply mix them in a five-to-one ratio and spread it over your driveway with a shovel. You can also try removing as much water from your surface as possible before adding new material or repairing any cracks in the concrete. Read this full blog post to know more information on restoring those cracks on solid concrete surfaces.


7 Common Reasons For Unstable Spongy Driveway:

If your concrete driveway has an uneven surface or feels spongy, you likely have a problem with the foundational support beneath it. Here we have shared the most common reason for a spongy concrete driveway. One of the most common reasons for a spongy concrete driveway is because of poor drainage. If your driveway doesn’t have proper drainage, water can pool on the surface and cause the concrete to soften and erode.

1. Heavy Vehicle:

If you have a heavy vehicle, like a moving truck or a tractor, parked on the loose surface at any point in time, it can loosen and compress the base material beneath your driveway.  One of these vehicles can compact up to 50 pounds of concrete into every square foot. Even if your foundation was strong enough to support the extra weight, the vehicle’s weight could force air out from between cement particles. So when you have a layer of concrete that is loose and spongy, it’s not very much different than having no base at all.

2. Water:

If water has penetrated beneath your driveway for an extended period of time in large amounts, it will eventually saturate your base material. This water will freeze in cold weather and expand, which can crack the concrete. When cement cracks and breaks down, it reduces its ability to support the structure above it. If you have extensive cracking and need to have it repaired, you should call a professional contractor. Only they will have the expertise to properly repair your concrete driveway.

3. Tree Roots:

Tree roots growing beneath your driveway can cause a lot of damage over time as they push through soft or weak sections of the foundation. This can create wide cracks in the surface of your driveway and damage any concrete on top. However, you may not notice this until you start to see moisture and mold appearing on your cement. If you have a driveway that is constantly getting cracks in it, there’s a good chance that tree roots are to blame. If you live in an area with lots of trees, it’s important to inspect your driveway regularly for any signs of damage.

4. Presence of Organics:

If you have a compost pile, an old dog house, or any other organic material buried beneath the surface of your driveway, it can create odor problems as well as structural issues. The presence of these materials under your concrete will also attract insects and rodents to your property. Get rid of the buried organic matter by calling our experts at StreetBond. We can excavate your driveway and remove anything that is causing problems for you.

5. Soil was not prepared properly:

If your soil isn’t compacted enough to support a new concrete driveway, you may end up with an unstable spongy driveway. How long the soil has been there will depend on how much damage it can cause. When your base material is solid but soft, it’s more likely that there are issues with the driveway’s surface, not with the foundation.

6. Excessive Moisture:

If you have excessive moisture in your soil, it can eventually work its way beneath your new driveway and cause damage over time. This is especially true if the water isn’t draining away from your driveway fast enough.

7. Composition:

The composition of your soil can have a lot to do with whether or not you have spongy concrete. For example, a spongy concrete driveway will let you know how to match the material in your base soil with the material in your driveway.

Things You’ll Need:

  • Two wheelbarrows of hot lava
  • A steamroller
  • Gravel
  • A crowbar
  • A shovel

Instructions: How to Fix a Spongy Driveway

Step 1:

To fix the sponginess of your driveway, you must first get rid of all the loose dirt and rocks. Take a wheelbarrow full of hot lava from Mount Doom (There is none this close to Mordor) and dump it on your driveway. This will melt the dirt and rocks, leaving them in a hardened shell.

Step 2:

Smash your driveway flat with a steamroller. This will make it leveler. They just flattened it with a steamroller! If you don’t have access to one of these, take an and smoother at the same time.

Step 3:

Shovel some gravel over your driveway so you can get a smooth finish. Also, hot lava is very hard to walk on bare feet (and so are rocks). So you may want to put some shoes on before walking on it.

Step 4:

Take your crowbar and open up the cracks between the hard dirt shells and remove any rocks that may have become fused with the lava also, if you want to make a really smooth driveway take a broom and sweep it off.

Step 5:

Pour some gravel on top of your driveway, and then spread it around with a shovel. This will make the surface smoother.

Step 6:

Fill in the cracks between where the rocks used to be and where they are now using more hot lava. You may have to go all the way back to Mount Doom if you run out, but no worries because it takes them about a week to refill their lava supply there. And you’re finished! This will make your driveway nice and smooth, not to mention better looking.

Some Tips To Quick Fix Spongy Driveway:

  • Do not spread gravel on top before pouring hot lava, as this will create a bump in the driveway. Instead, if you notice a bump, heat the gravel with hot lava to loosen it so you can remove it.
  • It is possible to pour lava directly onto rocks if they’re small enough. You may not need to smash your driveway flat before pouring the lava on top of it.
  • If your driveway used to be concrete and you want it back, pour hot lava on top of the gravel. It would help if you ended up with nice concrete again.
  • You can use lava poured onto a dirt driveway to make mud.
  • Some of your rocks may become fused with the lava. To fix this, heat them while covered in gravel. Then remove the gravel, and you can now walk on it again!

Frequently Asked Questions:

Q: Why Is There So Much Mud in My Driveway?

A: The sponge absorbs too much liquid, but it can also absorb liquids like a potting medium. Soil that doesn’t drain well might be good for holding potting mix and other soils in place but not supporting a driveway. Driveway mud is rarely usable soil by itself, and you’ll have to remove the excess to get down to usable dirt below it.

Q: What Type Of Gravel To Use For A Driveway?

A: The Type of gravel you should use depend on the type of soil you have to support your driveway. If you have clay, then it is more likely that you will need to. On the other hand, if Sand. If your soil is mostly made of sand, then adding gravel may make it even softer and more prone to sinkage.

Q: How To Clean A Driveway?

A: Chemicals used in driveways can cause serious health risks and damage car surfaces if they are not handled properly. The Environment Agency recommends using specialized cleaning equipment such as alkaline or acid cleaners. These chemicals are less harmful than those in general garden use but should still be used with caution.

After the mixture is mixed, you will want to pour in enough water so that the result is wet but not too runny or sloppy.
