Negative pitch, also known as negative slope, is a common problem in homes that can have major effects on your property and your enjoyment of it. If you're wondering what negative pitch is and what effects it can have around your home, you've come to the right place. In this post, we will discuss how negative pitch can affect your home, as well as the different ways to fix it.
What is Negative Pitch?
Negative pitch refers to a slope where the ground slopes towards the house rather than away from it. This usually causes rainwater and other runoff to accumulate around the foundation, which can lead to a variety of problems. Negative pitch is typically caused by a poor grading job during construction or the settling of the property over time.
How Does Negative Pitch Affect Your Home?
1. Water Damage
The most significant effect of negative pitch is water damage, and it can cause extensive damage to your home's foundation, walls, and other components. Water can seep into the foundation, leading to the development of mold and mildew, and cause wood to rot, leading to structural damage and decay.
2. Structural Issues
Negative pitch can cause significant structural problems, especially if it is not remedied promptly. The accumulation of water around your home's foundation can cause the soil to expand and contract, leading to foundation cracks, uneven floors, and unstable walls.
3. Poor Drainage
Water accumulation from negative pitch can also create poor drainage in your yard, making it difficult to enjoy outdoor activities. The standing water can create puddles that become breeding grounds for mosquitoes and other insects, resulting in a higher risk of disease transmission.
4. Heaving Floors
Negative pitch can also cause heaving floors, a significant problem in homes with concrete slab foundations. As the soil expands and contracts due to water buildup, it can lift and separate the concrete slab, causing it to become uneven and unstable.
How to Fix Negative Pitch
There are several ways to fix negative pitch, depending on the severity of the problem and the underlying cause.
1. Reslope the Yard
The most common solution to negative pitch is to reslope the yard so that it slopes away from the house. This involves regrading the area around your home's foundation to ensure that water drains away from it. This can be done by using soil or by installing drainage systems.
2. Extend Downspouts
Another affordable solution is extending your downspouts away from the house. Keep the runoff as far from the foundation as possible. The goal is to reroute the water away from your home.
3. French Drains
If the negative pitch problem is more severe, a French drain is an effective solution. This is a system that involves digging a trench around the foundation of your home and installing pipes that channel water away from your foundation. You'll need a professional for this installation and the price can vary.
4. Install a Sump Pump
A sump pump installation is also a great way to deal with water accumulation caused by negative pitch. Water will be lifted out of the sump basin and directed further away from your home. If you decide to install a sump pump, it's a good idea to include a battery backup system.
Conclusion
Negative pitch is a serious problem that can lead to significant water damage, structural issues, and poor drainage in your yard. Luckily, there are several solutions, including resloping the yard, extending downspouts, installing a French drain, and installing a sump pump.
In taking care of negative pitch, there are different ways people can go about it. However, it's best to consider your unique situation and seek the help of a professional if necessary. With these tips, you can help prevent negative pitch and avoid severe damage to your home.
