"Alpha Foundations did an excellent job on our lanai. In the process of stabilizing the lanai slab, they remedied the cracks and uneven surface caused by a combination of ground settling and improper installation during the initial house construction. They were knowledgeable and professional, explained what they were doing very well, were very detail oriented, and demonstrated great customer service. They exceeded our expectations and we would very much recommend them to others needing similar services."

"Rod & the guys at SealProMax have been incredibly accommodating and helpful throughout the stressful situation which was my leaky basement. Rod came in and was able to describe how their product works, gave a live test sample, then explained that they will use as much solution as necessary to stop all water from entering my basement. After 3 days worth of locating and filling cracks & air pockets with their material, it appears that my basement no longer will see flooding every time it rains. They have been adamant about the quality of their product and have given me the piece of mind knowing that they will return as many times as needed in order to ensure that our problem will not return. Add all of this on top of their warranty and I can happily say that their service has been well worth the money spent. I would recommend Rod & his crew to anyone in need of waterproofing any leaks in their basement who are willing to spend their money on a product & service that cannot be matched."

"Outstanding Concrete Work – Highly Recommended! I recently had my patio renovated with concrete, and I couldn’t be happier with the results! The team was professional, punctual, and extremely detail-oriented. From the initial consultation to the final finishing touches, they demonstrated top-notch craftsmanship and expertise. The quality of the concrete work is exceptional—smooth, durable, and perfectly executed. They also paid great attention to the design, ensuring it complemented my outdoor space beautifully. Not only did they complete the project on time, but they also kept the area clean and organized throughout the process. If you’re looking for reliable and skilled professionals for concrete work, I highly recommend them. They exceeded my expectations in every way, and I will definitely hire them again for future projects!"

"We hired them for the front walkway and driveway - we were very happy with the finished work. These guys were reliable and true to their word. He promised us it would take four days and it did even if he had to work extended hours to get the job done.! They are hard workers and you can tell they are professionals. We strongly recommend them for your concrete work."

"Excellent! The work was complete in 1 day without any mess. The owner even came back a week after to make sure all leaks were fixed and no more water in our basement. The workers were very courteous and prompt. The cost is way less than having the whole wall redone. I’m very happy with the outcome and I highly recommend them! Save yourself money and a mess for the same outcome!"

Masonry questions, answered by experts

Mortar is a mixture of sand and cement that binds materials, such as bricks, stones, and concrete blocks, together. Think of it as the glue that fills in the gaps between bricks and stones, then seals them in place to prevent damage or deterioration. Mortar also helps spread the load across a wall or structure, keeping cracks and shifting at bay.

It’s called cobblestone because it’s made of stones that are “cobbed” together. A cob is a term that refers to rounded lumps. Originally, cobblestone streets were made from pebbles and stones gathered from riverbeds that had been rounded over time by the passage of water. The term has nothing to do with a cobbler, which is the term for someone who makes and fixes shoes.

Yes. Black stains are more than an eyesore. Some black stains can pose health concerns, especially for those with asthma, allergies, or other respiratory conditions. Some stains can also damage the brick’s structural integrity, harming the mortar and resulting in more expensive repairs.

Yes! Hot glue is an excellent—and temporary—way to spread holiday cheer with Christmas lights without damaging your brick exterior.

It is possible, albeit a lot slower, to break up a rock using water. You would do this by freezing and thawing the water. You could create some initial holes or cracks in the rock, then pour water into the cracks or holes and allow them to freeze (so it's best to do this in winter or in colder climates). Since water expands when it freezes, this puts pressure on the inside of the rock and causes it to crack. You could continue to pour more water in and let it freeze to continue to break up the rock.
