ABOUT OUR WORK

Protect Your Home From Basement Water

Affordable Basement Waterproofing provides professional basement waterproofing, crawl space encapsulation, sump pump installation, foundation crack repair and structural repair throughout Maryland, Washington DC and Delaware.

We have specialized in basement waterproofing since 1998, helping homeowners identify where water is entering and installing drainage systems designed to provide a long-term solution.

Find the Entry Point

We inspect walls, cracks, block cores and the wall-floor joint before recommending a system.

Install Lasting Drainage

Water is collected and directed to a sump pump before it can enter the finished basement.

HOW WE WATERPROOF

Basement Waterproofing Done the Right Way

Water entering a basement can come through foundation walls, block cores, cracks, the wall-floor joint or from water building up underneath the basement floor.

Our interior waterproofing systems are designed to collect that water and direct it to a sump pump before it can enter the finished basement area. Depending on the home, our waterproofing system may include:

  • 4-inch perforated PVC drainage pipe
  • Excavated interior drainage trench
  • Washed drainage stone
  • Filter fabric
  • Weep holes drilled into block wall cores
  • Wall drainage and vapor barrier
  • Sump pump and sealed sump basin
  • Exterior sump discharge
  • Antimicrobial treatment when required

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.

Complete Crawl Space Encapsulation

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

Wall Vapor Barrier

Foundation Crack Repair

Foundation Crack Repair

Foundation cracks are evaluated to determine whether the problem is water intrusion or structural movement, then repaired with drainage or reinforcement when needed.

Crawl Space Structural Repair

Crawl Space Structural Repair

Floor framing and support systems can require reinforcement. We install beams, adjustable steel columns, footings and sistered joists when conditions require it.

Sump Pump Installation

Sump Pump Installation

The sump pump is one of the most important parts of an interior waterproofing system. We install Zoeller pumps, sealed basins, check valves and battery backups.
