  2.  Installing a Sump Pump: A sump pump is an essential part of interior waterproofing. It gathers water from the drainage system and removes it from the basement with a pump. Sump pumps come in a variety of designs, such as submersible and pedestal pumps, and they may be fitted with battery backups for extra security during power outages.
  3. Basement Wall Sealants: Sealants for basement walls can assist stop moisture intrusion by being applied to the inside walls of the basement.

Injection of epoxy or polyurethane resins into the fissures results in the formation of a watertight seal. This technique successfully stops current leaks while also preventing future water ingress.

Membranes and coatings that are waterproof are crucial components of interior and exterior waterproofing techniques. These materials give another layer of defense against water infiltration. Bituminous membranes, rubberized asphalt, and polyethylene sheets are a few common waterproofing membranes. To form a waterproof barrier, various surfaces can be coated with waterproof coatings like elastomeric coatings or cementitious waterproofing solutions.

Landscaping Technique

Landscape design may have a big impact on waterproofing a basement. By properly grading the area surrounding the foundation, water won’t collect close to the basement walls since the earth will slope away from the home. Additionally, employing trees or bushes with deep roots might aid in absorbing extra moisture from the soil.

Window Well Covers

Basement windows are vulnerable to water infiltration, particularly if they are below ground level. By installing window well covers, you can stop snow, ice, and rain from building up in the window wells.
