"We had started to get water coming in from the foundation of our basement. Sean had come to our home to give us our best option and estimate of what work they would end up doing. Overall it seemed like the best choice, and sure enough, it was. We had french indoor drains installed in our basement, along with an updated sump pump with a battery backup incase of power outages. Ever since this was completed, we've had no issues, and our basement is fully dry. It only took a few days to complete, and they did a great overall job!"

"Arid did an amazing job! The sales rep, Mike who came out to give us an estimate was very knowledgeable and explained how the whole process worked. He was very patient answering my three pages of questions! The work they did and the equipment they installed was exactly as promised. I stressed out for so many years about getting French drains because I heard it was so messy and you get dust throughout the whole house. I followed their printed recommendations and there was virtually no dust in the floors above the basement. The Foreman, also named Mike, brought a crew of seven men and ran the job like clockwork. The job was completed in just 5 1/2 hours. They cleaned up every piece of debris and even washed down my driveway! Mike explained how the system works and left me all the manuals. I went with their backup pump and battery system, which they designed, for extra peace of mind. I would recommend Arid to anyone thinking about getting French drains. Thank you Arid!"

"Bob and his crew were great! They installed a sump pump and drain in a part of my basement that had water for the chest time in 25 years. They also checked and repaired all my gutter leaders to make sure any clogs could be easily accessed. I highly recommend them!"

"These guys could not be more terrific! They were able to diagnose a problem that no other waterproofing could. American A-1 was here 5 minutes and they knew exactly what our problem was. We didn’t know it but we have iron oxide in our ground which needs to be maintained yearly. Also our french drain hadn’t been dug out deep enough to begin with so our finished basement got completely ruined. It was a very low point in our life but these guys came in, did the DIRTY job with HEAVY lifting and never complained once. They were efficient, knowledgeable and cleaned up to perfection when they were done. They even paid for a cleaning service to come in as dust had gotten just about everywhere. At another point in time our window wells were filling up with water and we didn’t know why. They came the next morning and figured out a drain pipe had been punctured by our underground sprinkler company. They did the work that day and it’s been perfect ever since. They could not be better at what they do. I’m in awe of how knowledgeable they are and how hard they work! Thank you to everyone at American A-1 for solving our problem, working hard, and allowing us the ability to enjoy our basement again!"

Foundation Drain Installation questions, answered by experts

A sump pump battery backup can typically run for 6 to 24 hours. The factors that affect its runtime include the battery capacity and pump usage. 

When purchasing your backup system, take these factors into consideration to determine which system is best for your home. If you live in an area with frequent and long-lasting power outages, consider a longer-lasting backup battery.

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.

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.

There are a couple of similar alternatives you may consider for a sewage ejector pump, including a grinder pump or a submersible sump pump. Submersible sump pumps protect your home from flooding from outside water, though, rather than handling wastewater from inside. A grinder pump macerates, or shreds, solid waste before pumping it onward to the sewer line.

A sump pump can be added to an existing basement. To do this, you will need to use a jackhammer or sledgehammer to break up the concrete and dig a pit. You will also need to create a hole in your basement wall to run the discharge pipe through.
