Comprehending the Reasons for Basement Flooding

Before we proceed with the tips for DIY basement waterproofing, it is imperative to grasp the reasons for basement flooding. Basement flooding commonly occurs due to three main factors:

  1. Inadequate Drainage: If the gradient around your house slopes towards your foundation, water can gather and infiltrate your basement.
  2. Sump Pump Malfunction: Sump pumps are responsible for draining the water that collects around your home’s foundation. If the sump pump fails, water can collect and flood your basement.
  3. Cracks in the Foundation: Tiny cracks in your foundation can allow water to seep into your basement, particularly during heavy rainfall.
