Denver Basement Waterproofing

Discovering a wet, damp, musty basement or crawl space is a homeowner’s nightmare.  

For many in Denver and the surrounding area, the nightmare is all too real. Thanks to the area’s clay loam soil, homeowners often see water in their basement or crawl space when rain or snowmelt occurs. Water damage and excess moisture aren’t ever a one-time problem. 

The first time you notice the problem won’t be the last. The water leak will continue until you call a reliable waterproofing expert. Installing a permanent waterproofing system can save you money long-term and even help you avoid health problems from mold inhalation.  

The experts at Groundworks have more than 20 years of experience repairing Denver area homes. With more than 1,300 positive reviews, local service awards and a free inspection, there is no reason not to call. Contact Groundworks to schedule a time to meet with our friendly inspectors.

What Causes Basement Waterproofing Problems?

Your Denver home is impacted by the soil and the weather conditions more than you think. It’s the area’s clay loam soil that’s the most problematic. Soil with a high percentage of clay easily absorbs water and expands quickly if the proper drainage system is not installed or has failed at your home. Since Denver receives only 15 to 20 inches of rainfall annually, significantly less than the national average, when rain or snowmelt occurs, the molecules in clay soil are ready to absorb the liquid as quickly as possible.  

This wet soil surrounding your home’s foundation doesn’t drain well and commonly finds the path of least resistance into your home. As a result, you may see or feel water on basement walls, see water damage where the floor and wall meet, or notice a basement leak over the top of the wall. Water can enter due to hydrostatic pressure caused by the heavy clay loam soil or because concrete is porous and absorbs water surrounding the foundation.  

Regardless of the reason, a permanent drainage system must be installed to stop the problem before it becomes more costly by stealing value from your home and putting your family at risk. Mold easily grows in damp, dark areas, and spores travel through the house because of the stack effect.  

Our Patented Basement Waterproofing Solutions

If you’re struggling with a basement waterproofing problem or water in your crawl space, Groundworks has permanent options for a fix it and forget it solution. You can feel confident you’ll receive a custom repair for your unique home. Below are a few solutions your Groundworks inspector may suggest.  

Sump Pump in Basement 3D

Basement Sump Pump 

The most common solution homeowners in Denver think of when dealing with a wet basement is a sump pump. It’s essential your sump pump is properly functioning and built to last. Often the big box store units won’t do. If you can’t trust your sump pump during wet weather, what good is it? 

Groundworks offers the most powerful lineup of sump pumps available. We have answers to clogged sump pumps, failing switches, power failures and provide remote monitoring services. Our sump pumps offer ultimate peace of mind protection regardless of whether you’re at home for a rain event.

Interior Drainage 3D

Interior Drain

Similar to a sump pump, homeowners in Denver may be familiar with a French drain to solve their basement waterproofing needs. Groundworks offers AquaStop BasementGutter™. Similar to a French drain, this patented drainage system is placed inside the home along the perimeter walls, collecting water from both the walls and the floor.  

Water is redirected to a sump pump, where it is pumped out and away from the home. The clog-free interior drain prevents groundwater from pooling and flooding your basement. Protecting your home’s structural integrity, your personal belongings, and your investment.

Basement Dehumidifier  

Although not always needed, a basement dehumidifier is an excellent solution to remove water from the air in your basement. Keeping the humidity levels in your basement or crawl space is essential since mold can grow easily in humid areas, even without standing water.  

After addressing the water issue, a basement dehumidifier may complement your basement waterproofing solution nicely. Not all dehumidifiers are created equal. Groundworks offers an energy-efficient, self-draining unit capable of removing up to 100 pints of water per day and filters up to 280 cubic feet per minute.

I had this company come give me an estimate for raising my back porch cement slabs that had fallen away from my house for years. A very nice guy named Peyton Peeples has been my contact person. He is very knowledgeable in what needed to be done. Every time I contacted him, he was quick to respond to all my concerns and questions.About a month ago, I had the company come and do the work. They were quick and cleaned up wonderfully after done. The guy that came and did the work was named Tyler Moorehead. He walked me through everything his team was going to do and made sure I understood and agreed with him. After the work was done, he went over everything.My porch looks SO much better!! They lifted it, filled in all the cracks, and caulked the whole thing so it looks neat and tidy. I'm not embarrassed anymore to have people see my back porch. THANK YOU!!!

Matt Daily is a wonderful, professional, humerous, warm, easy to communicate with individual. All the positive accolades you can imagine are applicable to Matt. If the Complete Basement Systems install goes as well as Matt's presentation, we will be extremely pleased, and entering an additional review afterward. Had we not entered into a Contract for services, we would still have acquired a new life-long friend in Matt Daily.

I had 2 crawl spaces in my home encapsulated by Complete Basement Systems. Phil Haggerty was the contact person and did a very thorough inspection of both spaces and found an issue we were not expecting. He did not put any pressure on us to use his business and was very good at answering questions, addressing concerns. He returned calls the same day, if I didn't talk to him when I called. HIs crew- 2 gentlemen both named Jose, were very professional and friendly. They covered the entire path from the basement to the garage with plastic to keep everything neat. They showed up on time, worked the whole day and did a great job. I would recommend using CBS.

I called Groundworks to level my driveway and repair the back patio. They came out and gave me a fair quote told me how they would fix the areas. They were on time and completed the job in just a few hours. Happy Homeowner! they did excellent work I was very impressed. After a couple of months to me it just didn't look right. I wanted them to come out and fix it under warranty. I thought it would be a real hassle to get them to fix it to my likening. So, I called them, and they said no problem be out tomorrow to fix the issues. They arrived on time and an hour later they were finished! Happy Customer! You can't go wrong with Ground Works.

Carlos Castillo came out to do my bench marking after my job was completed. He was courteous, thorough, answered all the questions I had, and was just the nicest guy! I signed up for the 5 year bench mark to be done to make sure that the movement of my house is corrected, and would be thrilled if he was assigned to do that for me for the future. I highly recommend Carlos!

Edgar and Isaiah did a fantastic job leveling the columns supporting my front porch and roof. This was after a crew had tried but failed to complete the job several years earlier. They showed up exactly when they said they would, talked to me to make sure they understood exactly what I wanted done, and then got right to work. They let me know when they were ready to start raising the columns so that I could watch the progress and let them know when the porch was at the level I wanted. Even though they were short-handed, they got the job done quickly. I am very happy with the job they did.Brooks Myers

My sump pump went out and I did not realize it until late on a Friday night. 1/3 of my basement had standing water in it. I called and left a message Friday night around 10:30, knowing that they were closed on Saturday. However, first thing Saturday morning, they called me and were able to be out before 9 am. They fixed the problem and even cleaned up the standing water. They recommended ways to dry up the carpet faster. Ryan was very professional and not pushy at all. I really appreciate this business and will use them in the future for all my basement needs.

I am a property manager, and foundation issues on homes are the last thing anyone in my position wants to deal with. Fortunately I worked with Mike Kilduff to get my foundation repair taken care of. Mike was incredibly communicative and made sure to check in with me every step of the way. As the work started on my home, I was also fortunate to add Armando to my project team, as the foreman for the job. He and his crew worked hard and did a great job, they even closed some very big gaps in my brickwork, which is never something that can be guaranteed. I fully intend to use Complete Basement Systems / Groundworks for another property, and will certainly refer them to all of my contacts.
