How Excavation and Grading Can Prevent Flooding

Flooding in your home can cause considerable water damage, especially to your foundations, basement, and lawn. If flooding is a persistent problem in your home, you can contact Nobleton plumbing services if you need excavating and grading for your Nobleton residence. Here are some ways that proper excavation and grading can alleviate any flooding problems you may have.

 

How Excavation and Grading Can Prevent Flooding

 

  • Lot Grading

After enough time has passed, surfaces over your property can settle, causing those areas to be lower than their surroundings. When it rains, this makes it easier for runoff to slope down toward your home, contributing to flooding. Plumbers can excavate your driveways and patios to reach the support underneath and adjust it to make the ground more level. In case of relatively flat areas, excavation can be done where water collects the most.

The usual method is to slope the ground around the house with topsoil to keep water from getting into the foundation wall and flooding the interior. Grading can also be combined with other methods for more effective displacement of runoff.

  1. Exterior Excavation

Plumbers can opt to excavate immediately outside your basement to install new drains to divert water away from the house and foundations. Exterior excavation requires plumbers to make a sloped ditch and install pipes inside the ditch to give water runoff a path down the slope.

These drainage systems also include features like a French drain that can absorb water that seeps through soil and gravel. This can prevent your soil from becoming oversaturated with water, which contributes to runoff. This method can keep water out of your home and avoid flooding altogether.

  • Interior Excavation

Flooding inside your basement can be mitigated with excavation within the house. This entails digging up part of the basement within the walls and installing drains to redirect any water that collects there. The excavation can also include a sump pump to drain water out of the basement when water levels rise too high. The pump can discharge your water outside where it can flow away from your house.

  • Swale Installation

When grading your lot, plumbers can use the dug-up soil to make swales around your property. Swales are wide, gently sloping channels that divert water down and away. Their slope lets them direct water away from the house, while their width allows more water to flow at a time. This makes the runoff flow more slowly so the drains aren’t overwhelmed by the amount of runoff.

  • Downspout Installation

Downspouts deposit runoff toward a street or swale roughly 1.8 metres away from your home. This prevents the flow of water toward the weeping tile around the house’s foundation and overloading it. Grading your lot also comes into play here. Your lot must be sloped properly to let runoff drain away from your home.

  • Rain Garden

You can also have landscapers install a rain garden around your property. A rain garden is a planted depression meant to absorb runoff from impervious areas like roofs and driveways. This allows rainwater runoff to soak into the soil instead of flowing away via storm drains, which can still cause erosion and flooding.
