Can You Concrete Over Weeds?

Posted on: July 23, 2022

The answer to the question “Can you concrete over weeds?” is “no.” It’s impractical to pour concrete over weeds because the weeds may grow back and seed. However, there are some solutions. Use polymeric sand and a propane torch to get rid of weeds. Alternatively, you can use a chemical weed killer. But remember: this option is not permanent.

Pouring concrete over weeds is impractical

It may seem like an easy solution, but pouring concrete over weeds is not a good idea. The soil below it is too porous for concrete to support itself. The soil underneath will soon deteriorate. That will result in cracks in the concrete, and you don’t want that to happen. It is also not a good idea to let weeds grow up through the concrete.

Grass seed can grow on concrete

When planted on a concrete surface, grass seed grows well. It requires minimal fertilization and intermittent watering in order to grow and flourish. The cracks in the concrete create a network of tiny pores which allow water to reach the ground. When grass is provided with sufficient water and nutrients, it will thrive and grow. If it’s not watered enough, grass will die. If it’s too dry, it will turn into weeds.

Whether grass seed can grow on concrete is a matter of research. Some grass seed claims to grow on concrete, but research indicates that this doesn’t always work. In the event that it does, you may need to break up some of the concrete before you can plant the grass seed. If you’ve got a septic tank that is not buried deeply enough, you’ll need to dig it up.

Using polymeric sand to prevent weeds

Polymeric sand is an inexpensive way to keep weeds from growing in your backyard. Unlike regular sand, it does not allow them to grow through concrete. It does not stop them from growing, however, if the weeds are highly prevalent. You can remove the old sand to prevent weeds from growing in the future. You can also try other methods like using vinegar.

To use polymeric sand, make sure to apply it between the joints of your interlocking pavers. Then, apply it according to the manufacturer’s instructions. When the polymeric sand has cured, it is hard to touch, which makes it less attractive to weeds. Furthermore, this weed killer doesn’t contain moisture or any nutrients that weeds need to grow.

Using a propane torch to remove weeds

Using a propane torch to remove invasive weeds from your lawn or garden is a great way to eradicate them quickly. A torch can be used safely as long as you follow certain safety precautions. Typically, you only need to expose the weed to the flame for about a 10 second period in order to kill it. You should also use a propane torch on soil that has been wetted, as the heat from the flame will be transferred much more efficiently and effectively. You should also have a fire extinguisher and garden hose near you. Also, you should use a sparking tool to ensure that you do not ignite the torch, and long matches should be avoided because of safety concerns.

Weed torches come in many sizes and models, so you can use one for a backyard weed removal project or for a driveway. Using a propane torch has been gaining popularity over the last few years, and today, you can choose one that fits your needs. For instance, there are small hand held propane torches that are perfect for walkways and patios, while larger propane torch models are great for large jobs.
