Any materials that will potentially hold moisture close to the house can also exacerbate any mold and mildew issues in cavity walls, as well as encourage insects and rodents to make homes along the space between rocks and siding (and eventually in siding).
One subtle advantage of rocks is security. Compared to mulch, rocks create noise from people moving about on it, and it's often used in shrouded areas like behind shrubs, right up next to the house. Dogs especially can pick up on it, but depending on the rocks, so can humans.
Unlike mulch, rock landscaping doesn't attract bugs. Some pests may hide underneath the rocks, but since there is no food source, they won't stay. Mulch on the other hand decomposes and then attracts pests. Also, depending on the mulch you buy, it can attract termites so keep this in mind as well.
We recommend using coarse gravel that encourages drainage and can be installed by applying an even layer that creates a sloped surface, drawing moisture away from the foundation. Mulch: Organic mulch, such as wood chips or bark mulch, helps to regulate soil temperature and retain moisture.
Gravel (and other rocks) act as barriers that shun rain and other forms of precipitation away from a building's foundation. Another benefit of using rock for drainage is that exposed rock absorbs the heat from sunlight more than other materials like mulch. Rock then radiates this heat at night.
Fewer pests: Because mulch is made of wood, it tends to attract pets, some of which can wreak havoc on your house; termites, for example. Conversely, with rocks, there's no need to worry about pests, because it doesn't attract bugs or insects.
Choose from brick chips, crushed gravel, lava rock, river rock and marble to create pathways, mulch for garden beds, driveways and more. These popular types of landscaping rocks are widely available.
When it comes to landscaping to divert water from the house, gravel is an excellent option. It is vital to note the benefit of rocks around the house for drainage. Ensure the gravel bed does not slope towards the foundation.
Installing a concrete walkway around your house is an excellent way to protect the foundation.
Avoid using mulch and large rocks in your landscape, as they attract snakes and their prey and can create breeding and overwintering habitat. Instead, use smaller, tight-fitting rock such as gravel or river rock. Also avoid landscaping with water gardens and Koi ponds.
Adding things like gravel, rocks, or pavers to your yard can make it less welcoming for rodents. These materials don't provide many hiding places, which helps keep rodents away.
Mulch fades and breaks down over time, so you'll need to replace it every spring. Some Level Green customers replace it twice a year, in spring and fall, to ensure it always looks fresh. Rocks on the other hand, require little maintenance. They may need an occasional washing to keep them looking clean and tidy.
For most purposes, about 2 inches of material will be adequate. If you're using materials that are themselves larger than 2 inches, then the depth will probably be the size of the rocks, that is, you'll just want one layer of 3-8 inch rocks.
Landscaping Fabric
Before laying down mulch or gravel, add protection by using landscaping fabric. This fabric acts as a barrier, preventing weeds from growing while still allowing water to drain through. It's an excellent way to maintain a neat and tidy appearance around your foundation.
Water in the soil around a home puts pressure on the foundation that can cause cracks, leaks, and structural damage.
Coins as Good Luck
Another way to begin a good tradition that's going to be hidden but meaningful is to drop one or two coins into the forms of the foundation before it is poured, or directly on top of the slab during the pour.
To fix or improve the grading, you can add soil next to the foundation and slope away from the house, however, you should have at least four inches of your foundation (concrete, block, or stone) showing above the soil. The soil and vegetation should not be in contact with the siding or any wood.
Grading drainage is one of the most efficient ways of providing drainage around a home's foundation. Grading drainage involves creating a slope around the perimeter of your home that leads water away from its foundation.
Inorganic mulches like pea gravel or rubber mulch do not support the life cycle of pests that require organic material, thus, they might be a better choice in areas prone to infestations.
Stones and rocks, including gravel, are the best materials to put around your foundation. These rocks are not only more appealing, but they are durable, versatile, and the best way to move water away from your home. Water drains most efficiently in gravel so you can prevent pooling.
But, generally, using organic mulch made from wood chips or bark will be the best choice. It's one of the easiest and least expensive ways to ensure the long-term health and fertility of your soil and the health of your trees and shrubs.
Pea gravel is one of the best materials for landscape drainage because its small size allows for outstanding drainage. These rocks are only about ¾ inches in size. Pea gravel is available in a variety of shades, including brown, grey, blue, and red, making it a good choice for a number of different landscapes.
