Yard work: Lot grading
Protection from floods and foundation damage
Direct rainwater and snowmelt away from your foundation
Proper lot grading ensures that the soil around your home slopes away from the foundation at a recommended gradient. Proper lot grading directs rainwater and snowmelt away from your foundation, reducing the risk of basement leaks, foundation damage, and mold growth. This can be combined with other flood protection measures to create a strong defence against flooding.
What to look for
- The ground should be sloping away from the foundation on all sides.
- One way to determine current grading condition of the house is to look for reverse sloping or water pooling around the foundation of the house.
- A contractor willing to do a proper site evaluation who has experience, certification and insurance.
Things to consider
- Confirm the inclusion of any swales, retention areas or French drains when planning lot grade design.
- Check local by laws and conservation authority guidelines.
- How grading will affect other existing waterproofing measures.
- How your grading plan affects the neighbours plot of land.
Average cost
Largely depends on lot size but residential homes average $1,150 to $3,500
