"Our basement wall had settled over five inches.  They piered the front basement wall and brought it back up to level.  The basement wall was beyond repair.   They cut a section of the back basement wall and demolished the entire back wall and poured me a new basement back wall.  Great job guys!!!

"As a project manager in the construction industry I can tend to be a little overbearing when it comes to hiring contractors to work on my own home. During the discovery/bid process Cody was extremely knowledgeable and helpful with explaining the issue and the options we had to remedy my problem. Their bid came in at a fair value and below what I was as expecting so we signed the contract to move forward with the work. Olshan installed 8 cable lock st piers to lift and stabilize our foundation. Alejandro was in charge of the actual work on our home and he is an absolute rock star. He was extremely knowledgeable and went above and beyond to ensure that the job was performed correctly. His crew was respectful of our home and got in and out as quickly and cleanly as they could. Alejandro answered all texts and phone calls in a reasonable amount of time and always kept me in the loop. Overall, foundation work is tough but Olshan made it look easy. Cody and Alejandro were exceptional throughout the process and I trust if I ever need anything in the future they will be there for me."

"Admittedly, I only had them waterproof my basement 2 weeks ago and we haven't had any especially heavy rain storms since. However, I haven't had any noticeable water issues since. The staff were very friendly, courteous and worked very hard. They were able to complete the work in just one day. Which surprised me, considering that their crew of three guys channeled the whole basement and installed two sump pumps. Their work definitely seems solid, so I wouldn't expect any issues. They did come highly recommended to me by my son, who had them do his basement as well and he hasn't had issues for over 2 years."

Basement Waterproofing FAQs, answered by experts

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Thankfully, you do have a few sump pump backup options in case it fails. One option is a battery-powered backup sump pump. Another option is using a portable backup generator as a power supply for your sump pump. Unlike a battery-powered backup which has limited power, a generator can run around the clock for as long as you need it. 

Or you can opt for a water-powered backup pump, which uses your home’s water supply as a source of power. However, this may not be the best option if you find your house frequently has low water pressure.

Topical sealers adhere to the surface of concrete to create a protective layer. In many cases, this is all you need for concrete that sees light to moderate traffic, such as your basement. Penetrating sealers, on the other hand, bond with the free lime in the top layer of concrete to form calcium silicate, which prevents liquid from passing through. This type of sealer protects the surface from water, oil, and gasoline spills.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
