This basement was suffering from water intrusion due to blocked drain tile and downspouts that were directing water towards foundation wall and there was mold growth found underneath flooring. To fix the water issues, and ensure all water was collected and disposed of correctly and away from the property, we installed a  TripleSafe Sump Pump  and WaterGuard Drainage system.

The stability of any concrete surface is dependent on the soils beneath it. The weight of concrete and what it supports, combined with natural soil erosion, can lead to sunken and uneven concrete surfaces, like this long concrete front porch in Denmark, WI.  

Sure-Dry Basement Systems provides expert concrete repair solutions using the PolyLevel® system. PolyLevel® is an expanding polyurethane foam that is injected beneath the concrete to fill the gaps caused by soil erosion and raise and stabilize the concrete surface.

If you have sunken concrete surfaces you need repair, call us today or contact us online to get started with a free estimate!

Job Stories From Denmark, WI
Concrete Repair Services in Denmark, WI

When the Denmark homeowner reached out, their goals were clear: eliminate trip hazards, stop water from collecting on the slabs, and avoid the cost and disruption of full replacement. Our inspection confirmed settlement from voids under the concrete and failing joint sealant that allowed water to penetrate and worsen the problem.

We recommended a two-step repair. First, PolyLevel® was injected beneath the affected slabs. The expanding foam filled voids and gently lifted the concrete, restoring proper pitch for drainage. Next, we cleaned and prepared all cracks and control joints, then applied NexusPro® to create a durable, weather-tolerant seal that keeps water out and maintains a clean appearance.

 

The project was completed in hours, and the area was ready for normal use the same day. The homeowner now has level, sealed concrete that looks better, performs correctly, and is built to last through Wisconsin’s weather.

Basement Water Drainage System Installed in Denmark, WI

After inspecting the basement, we confirmed active seepage along several walls and found an undersized sump with no redundancy. We proposed a comprehensive upgrade:

  1. Perimeter capture: We installed WaterGuard® just beneath the slab along the leaking walls. The system was pitched to a new sump location for optimal flow and service access.

  2. Pumping capacity and redundancy: We set a TripleSafe® liner with primary and secondary pumps, airtight lid, check valves, and a battery-backup pump to maintain protection during outages or extreme rainfall.

  3. Freeze protection: On the exterior discharge, we fitted IceGuard® to provide an escape path if the line ever freezes, eliminating the risk of basement backup in winter.

 

We finished with concrete restoration at the trench and thorough testing of both power and backup modes. The homeowner now has a permanently managed drainage path, robust pumping capacity, and winterized discharge—delivering a dry, dependable basement in every season.

Foundation Fixed & Spongy Floors Stabilized in Denmark, WI

When the Denmark homeowner called, the symptoms pointed to crawl space settlement: sagging joists, spongy floors, and misaligned doors. Our inspection confirmed inadequate support posts bearing on soil that had shifted over time. To restore structure without a full rebuild, we recommended SmartJack® adjustable steel columns.

Our crew prepared the crawl space by laying out support locations and installing engineered footings to create a stable base. We set galvanized SmartJack posts beneath the main girders, added a supplemental steel beam where spans required it, and slowly tightened the system to lift the framing back toward its intended elevation. Final adjustments were made with a laser level to ensure consistent support across the floor plane.

The installation immediately stabilized the structure and reduced floor deflection. Because SmartJacks are adjustable, the system can be fine-tuned in the future if conditions change, giving the homeowner confidence that the correction will last.
