Trusted Concrete Repair & Concrete Leveling in Reno, NV

This customer, Ben, called in with concerns of water intrusion in his basement. After we came out to do a no cost, no obligation consultation, we determined that there were cracks in his stem wall allowing ground water to seep in.

To resolve this problem, we supplied a machine and operator to dig out the basement wall in order to install a waterproofing membrane to the south and southwest corners of the structure.  This included scrapping and grinding the concrete after exposed and cleaning the wall in order to apply the primer and membrane. A pipe drain was then installed wrapped in a filter sock, and slopped towards a sump pump that will push water away from the house.

Now, Ben's basement will be dry, free from water, and ready to entertain! 

On this project, our crews went in to do some seismic retrofitting. Seismic retrofitting is the modification of existing structures to make them more resistant to seismic activity, ground motion, or soil failure due to earthquakes. Prior to the introduction of modern seismic codes in the late 1960s, many structures were designed without adequate detailing and reinforcement for seismic protection.

560 Mill Street in Reno is a perfect example. The structure had hollow cell masonry units (CMU) that were too weak to withstand an earthquake. The proposed fix was deep excavation and the installation of a MAT footing, a thick reinforced concrete slab supporting columns or walls and transmitting the loads to the soil and cast in place concrete reinforcement up the wall.

Madole Construction had a better solution. Instead we added high-performance, high capacity drilled deep foundation elements called micropiles to greatly increase load compacity. This required less excavation and therefore, less time. Additionally, we used shotcrete instead of cast in place concrete. Shotcrete is concrete sprayed onto a surface through a hose using compressed air. These changes in execution resulted in a 50% cost savings!

With better understanding of seismic demand on structures and with our recent experiences with large earthquakes near urban centers, the need of seismic retrofitting is well acknowledged. Now, this structure on Mill street will stand strong for many years to come thanks to our dedicated crews.

Madole Construction was consulted by Core Construction and Spanish Springs Construction to develop a shoring system that would allow a new inspection pit to be constructed inside the existing Regional Transportation Commission's Bus maintenance facility.  This job had some unique challenges.  The wall had to be constructed adjacent to and below an existing thirty foot tall Concrete masonry unit (CMU) wall.  Immediately behind the wall was a live 4" natural gas main and a 12" Sanitary sewer line.  To successfully accomplish this job Madole Construction used a variety of soil stabilization techniques including Supportworks Helical Piers, Shotcrete, and Injection Bore Soil Nails.  Madole Constructions Flexible and nimble approach secured the excavation successfully and allowed the general contractors to maintain the construction schedule.

Madole Construction completed at a crawlspace inspection of a home with a chronically wet crawlspace.  Cleanspace Crawlspace encapsulation was installed in summer of 2006. Crawlspace is still in excellent shape after nearly 10 years.

Madole Construction recently finished the lifting and releveling of concrete steps and stairs in North Reno. The soil beneath the steps had settled over time, causing the steps to sink and become unlevel.  Polylevel polyurethane foam was injected in order to raise the steps back into place and relevel them.

This foundation repair on River Flow drive is interesting because of the amount of structural distress the house had experienced due to settling soils.  This particular house was over 7" out of level and had some dramatic looking damage.  Once helical piers were installed the house was releveled and cosmetic repairs to drywall and stucco were rather simple.  This house went from a borderline teardown to a desirable property in a relatively short time.

Madole Construction Co. Inc  Releveled house that was sitting on expansive soils. The house was out of level approximately 3 1/2" from one end to the other.  The solution involved installing 58 287 helical piers to support the foundation. The house was also releveled to bring the house back to as built condition.  The next challenge involved installing a basement under the existing house.  With house supported on helical piers the crawlspace could be excavated and new basement walls installed with shotcrete.

Madole Construction also performed structural repairs at 305 Spokane St in Reno, NV, where the south portion of the building was constructed over an unconsolidated fill of a previous buildings basement. The existing footings and slabs of the basement were sinking, which is where Madole Construction came in! By installing micropiles through the unconsolidated fill and jacking the footings back to their original position, the foundation was able to be saved. The slabs were reveled using polyurethane foam.
