This crawlspace was submerged in water for months. Madole installed two temporary sump pumps to deter the water out of the crawlspace to start the CleanSpace encapsulation. Before picture you can see the mud and rubble created in the crawlspace from the water damage. Our crew dug trenches along with the pumps to dry out the crawlspace in order to put down the CleanSpace material to start the encapsulation. The after picture, you can see the crew successfully laid down the CleanSpace material and was able to dry out the crawlspace. Our CleanSpace encapsulation process for this job includes dehumidifiers to regulate the moisture/humidity in the crawlspace as well as SmartSumps to notify the home owner of any water that may be in the crawlspace one the encapsulation is complete.

Job Stories From Washoe County, NV
305 Spokane St

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.

How to put a basement under an existing house

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.

Jamon Drive Foundation Repair

Madole Construction Co. Inc recently completed repairs to two houses on Jamon Drive in Sparks Nv.  Both houses had structural distress and  caused by expansive clay soils.  There were stuck doors broken sheetrock and a broken truss on one of the houses.  Madole Construciton crews installed helical piers around the exterior, releveled floors and made structural repairs that restored the value of these homes to better than new condition.

Big Rig Jig Burning Man

The 2007 Burning Man Celebration had a unique requirement.  They wanted to display a 25 ton sculpture of two semi-diesel trucks, let 50,000 people look and climb through them and there could be no trace of the sculptures or foundations 30 days after the event was over.  Due to the unique requirements and the remoteness of the Black Rock Desert helical anchors were the ideal solution for this challenge.

Red Hawk Golf Course Sparks,NV

Red hawk golf course needed a elevated cart path to cross a protected wetland area.  Several regulatory agencies were concerned about disturbing the wetland.  Helical piers provided the ideal, rapid no dig solution.

River Flow Drive 89523

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.

Innsbrook Village Apartments Sparks, NV

Innsbrook Village apartments was an interesting project.  The complex consisted of 32 balloon framed two story apartment units with slab on grade foundations.  At the time the apartments were constructed in the 1970's there was a significant gravel pit immediately to the east.  The gravel pit continuously pumped water out of the pit to keep the area accessible to mining.  The Truckee Meadows flood of 1997 completely flooded the pit and destroyed all of the equipment.  At that time the owners determined it would  not be viable to restart a sand and gravel operation, the City of Sparks took ownership and today it is the Sparks Marina one of largest urban lakes in the area.  The consequence of this for Innbrook Village was that water tables in the area rose substantially and the foundations began to experience structural distress.  The owners of the complex explored a range of repair options and strongly considered complete demolition.  All 32 units were repaired using Helical Piers.  The foundations were underpinned and releveled and the units were remodeled.  This was an extensive project lasting over a year but the real success was that the units were able to be repaired for about the same cost as the demolition.

Sinking Concrete Steps Raised with PolyLevel in Reno, NV

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.

Wet Crawlspace in Ridgeview Reno, NV

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.

Unique Shoring Job at RTC Bus Barn Reno, NV 89502

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.

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.

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!
