Interior Basement Water Proofing Systems Designed to Control Water Intrusion

Water can enter a basement through foundation walls, block wall cores, cracks, the wall-floor joint, or groundwater building up beneath the basement floor.

Our interior basement waterproofing systems are designed to collect water and direct it to a sump pump before it enters the usable basement area. We evaluate the foundation, drainage conditions, and points of water entry to determine the appropriate system for your home.

Depending on the property and the conditions, an interior waterproofing system may include:

Drainage System

Interior Basement Waterproofing Drainage System

Water collected from the foundation walls and beneath the basement floor is directed through the interior drainage system to the sump pump and discharged away from the home.

Crawl Space Waterproofing & Encapsulation

Control Ground Moisture and Protect the Space Beneath Your Home

Crawl spaces can allow ground moisture to accumulate beneath a home, contributing to damp conditions, musty odors, and moisture-related problems. Water intrusion may also affect floor framing and support systems over time.

Affordable Basement Waterproofing provides crawl space waterproofing and encapsulation solutions designed to help control moisture and create a cleaner, more controlled environment beneath your home.

EXTERIOR WATERPROOFING

Exterior Excavation & Waterproofing

Address Water Intrusion From the Outside of Your Foundation

In some situations, water enters through the exterior foundation wall, making outside waterproofing an appropriate option. Exterior waterproofing involves exposing the affected foundation wall so its condition can be evaluated and the necessary preparation and waterproofing work can be completed.

Our Exterior Waterproofing Services May Include

  • Excavation along the affected foundation wall
  • Foundation wall cleaning and preparation
  • Parging and surface repair where appropriate
  • Application of suitable foundation sealing or waterproofing materials
  • Installation of exterior drainage components
  • Drain board or protective drainage membrane
  • Backfilling after the work is completed

The appropriate method depends on the foundation construction, the source of water intrusion, site conditions, and the condition of the existing wall.

STRUCTURAL & FOUNDATION REPAIR

Foundation Repair & Structural Solutions

Foundation problems can range from water entering through cracks to visible wall movement or deterioration of structural supports. These conditions should be evaluated to determine whether waterproofing, structural reinforcement, or a combination of repairs is appropriate.

Foundation Crack Repair

Foundation cracks should be evaluated to determine whether the problem is simply water intrusion or whether structural movement is involved. We repair foundation cracks and can provide additional drainage or structural reinforcement when conditions require it.

Complete Crawl Space Encapsulation

A crawl space encapsulation system helps isolate the crawl space from ground moisture and creates a cleaner, more controlled environment beneath the home.

SUMP PUMP INSTALLATION

Sump Pumps & Drainage Systems

Reliable Drainage Starts With the Right Sump Pump System

A sump pump is an important component of many interior basement waterproofing systems. It collects water directed into the sump basin and pumps it away from the foundation through a discharge system.

Affordable Basement Waterproofing provides sump pump installation and replacement, along with drainage components designed to support the needs of your basement.

Available Options May Include

  • Zoeller sump pumps
  • Primary sump pump systems
  • New sump basins and containers
  • Perimeter drainage connections
  • Check valves
  • Underground discharge extensions
  • Battery backup sump pumps
  • Secondary pump systems

The appropriate setup depends on the basement's drainage requirements, the volume of water collected, and the level of backup protection needed.

Billy and crew were incredibly professional, kind and thoughtful. Could not have asked for a better experience! The service was phenomenal, their attitudes made this whole process go from one of the most stressful events of my short home ownership in New Castle Delaware to one that I love. The results are beautiful, true craftsmanship. If you have a leaky basement, call Affordable Basement Waterproofing right now!

I received estimates from 7 different companies. After receiving the estimate from Affordable Basement Waterproofing, the owner came to my house to visualize a foundation crack and a line for the sump pump. Billy (the foreman) not only answered my questions, but also explained the process of what they were doing. Superior service!

New homeowner was worried her basement would flood before she remodeled. ABW did an excellent JOB in waterproofing all the perimeter. And.at the end $600 credit was given due to not needing additional work. I would definitely utilize this company again.

Billy from Affordable was honest and only suggested necessary reinforcement. After coming of a horrible experience dealing with the previous company (JES) during the review and quotation process, I was pleased with Billy and the Affordable team. They didn't try to pressure or scare me. If anything they were politely reassuring and willing to earn my business. On the day of work, they did a timely job despite the challenge of operating in a small crawl space. They were also receptive to a favor and replaced insulation on the water line, which made me tip them well. Now I'm rest assured the foundation of my house is well supported for decades to come.
