How Does Interior Basement Waterproofing Work?

At McDowell Drain Services, we use advanced materials and systems to effectively manage water from the inside:

Perimeter Drainage System

A trench is installed along the interior perimeter of the basement floor.
Drain tiles collect water seepage and redirect it to a sump pump system.

High-Performance Sump Pumps

Installed to remove collected water, sump pumps discharge it safely away from your home.
Our sump pumps feature backup systems to ensure operation during power outages.

Waterproof Wall Treatments

Protective membranes and vapor barriers are applied to the interior walls to block moisture and keep the space dry.

Crack Repairs

Foundation cracks are sealed with industrial-grade epoxy or polyurethane injections to stop leaks and prevent further structural damage.

Professional from first contact to job completion. Job was to install a sewer backwater valve but once the floor was opened, it was evident that a sump pump installation was also required. Quickly pivoted to accommodate the additional work scope and still meet the timeline completion. Stuart, the owner is knowledgeable, professional and puts you at ease. Alex the installer did great work and paid attention to details. He was always receptive to any questions or concerns. Would not hesitate to recommend them for your plumbing needs.
