Why Do Basements Leak?

Crawl Space Sump Pumps Built for Lasting Protection

A sump pump is an essential part of any effective crawl space waterproofing system. Installed in a sump pit, it acts as a collection point for water and is your best defense against flooding.

At Accurate Basement Repair, our crawl space sump pump systems are designed to work seamlessly with our other solutions, such as our crawl space encapsulation system. Our professional team tucks a durable 20-mil liner into the sump lid to create an airtight connection. This system is designed to discharge water cleanly out of the basin and up a discharge pipe at the wall, ensuring a tidy, professional finish.

What Does a Wall Membrane Do?

How the System Works: Clean, Efficient, Complete

  • Certified Foundation Specialist installing a channel in crawl space

    Drainage meets collection

    A perimeter drainage channel captures water along crawl space walls and directs it into a central sump pit, starting the removal process long before water ever puddles on the floor.

  • Sump pump lid and discharge line installed in a crawl space

    Watertight connection

    If the sump pump is part of a crawl space encapsulation, the 20‑mil liner tucks into the sump lid, creating a sealed, airtight system designed for long-term control.

  • Crawl space waterproofing discharge NDS drainage emitter in a yard

    Fast, clean water removal

    The pump discharges water through the wall via a discharge pipe, no unsightly hoses, no mess, just clean, out-of-the-way removal.

  • Basement sump pump newly installed

    Stay ready under pressure

    Pumps sit idle most days, but when heavy rain hits, the drainage system activates. Water collects, the pump kicks in, and your foundation stays dry.

  • Battery backup for a sump pump

    Backup for storms

    Power outages happen during worst-case weather, so our Foundation Specialists can include battery backups, giving you continued protection even when the lights go out.
