"Antonio and his crew were amazing. His crew reconstructed an exterior brick wall of my 250 year old house that had been damaged by car collision. They did a great job preserving the look of this old house, supporting the structure, realigning the old bricks and applying new mortar to the joints. Really impressive work! Thank you Antonio"

"Nelson the owner from Premier Basement came out and assessed my problem quickly. He is very professional, fair pricing, and walked me through a process that I knew nothing about with his vast knowledge and experience. I highly recommend him and his company. It was a great experience amongst so many who try to take advantage of you and price gouge with high pressure sales."

"The Situation:
We moved into a new home and discovered that the prior owner had created a makeshift water solution in the basement. We had been in the house for about 3 months and were getting increasingly anxious about this. The water was overflowing into the basement  and eventually running into the sump pit (which incidentally was sitting directly below our breaker box). The sump was exiting across the basement via a pvc pipe hung from the ceiling at an inverted angle. So a lot of the drainage water would backflow back into the pit , or just sit in the middle of the sagging pipe. 
Since we live on a high water table, this was the first major project I wanted to tackle. I researched and interviewed a few companies and after meeting with Bob (the salesman/engineer) we felt comfortable with American A-1s solution and timetable for the job. During the initial inspection we also discovered a bulge in our basement floor caused by hydrostatic pressure.

The Solution : 
French Drains running the perimeter of the basement and two new sump pits position away from the circuit breaker, but still at the lowest level. One of these pits houses 2 sump pumps. One positioned higher than the other in case the first one burns out. The second pit houses a water powered backup (http://www.basepump.com/Products/Basepump.html) positioned at a higher elevation than the standard pumps. This is in case of a power failure during a storm such as a hurricane. American A-1 recommended a different, less complicated water pump but after researching several online I decided on BasePump. I ended up having my own plumber install it , because of the comfort level I have with him. (RAM Plumbing)

The exit strategy was well though out. The exit is directly above the pits through our foundation wall. From there the PVC water pipe runs underground to a seepage pit underground in our front yard which pitches away from the house. While I would have preferred the water to run into the town storm sewers, there is an ordinance in Ridgewood that prevents this.

After the installation we were a bit concerned because the pumps were running every 5 minutes. However recently this has died down to about once ever 90 minutes. And I assume will decline further as the ground dries out from the winter melt. If not we may need to raise the level of our pumps a couple inches.

Lou the foreman of the job was amazing. He was EXTREMELY respectful of our property and concerns. This is not a trivial undertaking. You are essentially jack hammering cement from  your basement and having it removed. When you are buying these drains for the price of a down payment on a nice car, its great not to have to worry.

The only minor issue we ran into was with the electrical inspection. The American A-1 recommended electrician used switches that were not matched to my current breaker box. The inspector failed us for that. The electrician was back within a couple days to change them out and we passed with flying colors.

Anyway ... our basement has been dry since and with the exception of the pump frequency we have had ZERO problems.
Here are a couple pictures of the work ... the staining you see on the floor is just the new cements still not fully cured yet."

House Leveling questions, answered by experts

Trenching and boring are two distinct methods for installing underground utilities. Trenching involves digging a channel using equipment like an excavator, trencher, backhoe, or shovel. While it is a simpler process, it causes significant disruption to the surface, landscaping, and surrounding ecosystems.

Boring, also known as directional boring, is a less invasive alternative that uses a drill to create a tunnel for utility lines without disturbing the surface. This method is more precise and is ideal for installations that need to go underneath buildings, roads, or bodies of water. Although boring is less disruptive, it is generally more expensive than trenching.

It restores concrete, prevents replacement cost disruptions, reduces trip hazards, and provides stability at a lower cost.

It’s best not to perform mudjacking in the winter unless the ground temperature remains above freezing. Freezing temperatures can cause the slurry to harden too quickly, compromising its strength and longevity. Concrete is also more susceptible to cracking and splitting in cold temperatures, so there’s a higher risk of damaging the slab during the drilling and lifting process in winter.

Pros often use mudjacking or polyurethane foam injection to level a sunken concrete patio. Both methods lift the slab by filling voids beneath it. After properly compacting the soil beneath it to prevent future settling, the concrete may need to be removed and re-poured for severe sinking.

Yes, expanding foam (also known as polyurethane foam) can lift concrete. This approach, called polyjacking, involves injecting the foam rather than concrete slurry to fill voids and raise the concrete slab back into place. It’s often faster and requires smaller drill holes than traditional mudjacking, though it may come at a higher cost. Some contractors also prefer polyjacking over mudjacking for more damaged and delicate slabs.
