Protect your basement from flooding with expertly installed sump pump systems. From pit excavation to battery backup configuration, Koppers Waterproofing delivers reliable waterproofing solutions across Northbrook and surrounding Northbrook, IL communities.
Why Koppers Waterproofing
Four reasons homeowners across Northbrook, IL trust us to keep their basements dry, year after year.
We evaluate your water table, pit dimensions, and discharge requirements to recommend the right pump model and horsepower for your specific property conditions.
Correct pit size and placement are critical. Our crews excavate to code, line the pit properly, and ensure optimal pump positioning for maximum drainage efficiency.
Power outages happen during the same storms that cause flooding. We install automatic transfer battery backup pumps so your basement stays protected even when the grid goes down.
A sump pump that hasn't been tested in three years may fail on the one night you need it most. Our maintenance plans include float testing, pit cleaning, and battery capacity checks.
About This Service
A sump pump is the last line of defense between your basement and groundwater. When soil around your foundation becomes saturated during heavy rainfall or snowmelt, hydrostatic pressure builds against basement walls and floors. Without a functioning sump pump system in place, that water migrates inward through cracks, porous concrete, and floor joints. The result is not just standing water but structural damage, mold colonization, ruined possessions, and the kind of costly remediation that a properly installed sump pump could have prevented entirely.
Understanding how a sump pump system operates is the first step to appreciating why professional installation matters. The system begins with the sump pit, a cylindrical basin excavated below the basement floor level, typically 18 to 24 inches in diameter and 24 to 36 inches deep. As groundwater rises around the foundation, it naturally drains into this pit through a gravel bed and perforated liner. Inside the pit sits the pump unit itself, fitted with a float switch mechanism that activates the motor once water reaches a preset level. The pump then forces that water through a discharge pipe that routes it away from the foundation, typically to a storm drain, dry well, or a point in the yard well clear of the home.
Choosing between a submersible and pedestal pump design carries real consequences. Submersible pumps sit fully submerged at the bottom of the pit, making them quieter in operation and better suited for pits that accumulate debris, since the sealed motor is protected from splashing. Pedestal pumps mount the motor on a stand above the waterline, which makes the motor more accessible for inspection but leaves it exposed to humidity and noisier during operation. Most residential installations in Northbrook, IL benefit from submersible models, but the correct choice depends on pit dimensions, average water volume, and budget. Our technicians assess all three before making a recommendation.
Pump sizing is where many DIY installations go wrong. An undersized pump runs continuously during heavy rain events, overheating and burning out prematurely. An oversized pump short-cycles, meaning it activates and shuts off too rapidly, wearing out the float switch and motor contacts. Proper sizing requires calculating the gallons-per-hour flow rate entering the pit during peak conditions, factoring in the vertical lift distance to the discharge outlet and any horizontal run length. We take these measurements on-site and cross-reference them against manufacturer performance curves to select a pump with appropriate horsepower and flow capacity for your specific conditions.
Battery backup systems deserve serious attention for homes in Northbrook and across Northbrook, IL where summer storm activity frequently knocks out power. The most common approach pairs your primary AC-powered submersible pump with a separate DC-powered backup unit that runs off a deep-cycle marine or sealed AGM battery. When utility power fails, an automatic transfer relay switches operation to the backup pump without any action from the homeowner. Battery capacity determines how long the backup system can operate. We evaluate your typical water influx volume and recommend battery ratings accordingly, along with maintenance-free sealed units that eliminate the need to check electrolyte levels.
Water alarms and smart monitoring add another layer of protection. A simple float-activated alarm mounts inside the pit several inches above the normal high-water activation point; if the primary pump fails or is overwhelmed, the alarm signals before water reaches the floor level. Wi-Fi connected monitors can send text alerts directly to your phone, giving you early warning even when you're away from home. We routinely incorporate alarm systems into our installations because early detection prevents the escalation from manageable water intrusion to full-scale basement flooding.
Common failure points that our maintenance programs catch early include clogged intake screens packed with silt and debris, burned-out motors from continuous running during extended rain events, stuck float switches that prevent the pump from activating, corroded discharge check valves that allow water to flow back into the pit after each cycle, and cracked discharge pipes caused by winter freeze-thaw cycles. Each of these failure modes is preventable with annual inspection, cleaning, and component testing. Our maintenance technicians document the condition of every component, test the float switch manually, pour water into the pit to verify activation and cutoff, and inspect the discharge line from pit to exterior termination point.

Customer Reviews
"We had water in our basement every spring for years. Koppers Waterproofing came out, assessed the water table, and installed a properly sized submersible pump with a battery backup system. We went through two serious rain events this past season and stayed completely dry. Worth every penny."
"The battery backup system they installed proved itself last July when we lost power during a thunderstorm. I watched my neighbor across the street get an inch of water in his basement while mine stayed bone dry. Their technician explained everything clearly and the installation was clean and professional."
"Called on a Friday afternoon when our old pump failed. They had a technician at the house within a few hours, diagnosed the motor burnout, and had a new submersible unit fully installed and running before dinner. Fast, honest about pricing, and left the work area cleaner than they found it. Highly recommend."
