"Working with Alpha Foundations was an exceptionally positive experience from start to finish. The project manager, Joshua, came out to look at our cracking concrete patio, diagnosed the issue, and had a cost-effective solution for us. He also provided all the information we needed to get a quick approval from our HOA. The team that did the work, Tory & Blake, were on time, efficient, and highly skilled. Not only did they stabilize the concrete patio using their foam injection process, they spent a lot of time caulking and smoothing all the cracks (literally on their hands & knees) doing a meticulous job. The process worked so well, it actually lifted one section and eliminated a 1" difference in height so no more trip hazard either. This company clearly invests in a high quality product and skilled professionals. We are very glad we found them."

"The company charged $4000 for a pop-up drainage system to prevent flooding in my stand-alone backyard office. When heavy rain came, it was apparent that the system in place was not working, and despite multiple emails, no one responded for six months. When they did, they sent workers out to do the same job that was already done. They also told me that the system in place would not work and should never have been placed and in the end, recommended I hire an irrigation company, stating that they are not an irrigation company and, when asked about a partial refund since the system placed did not work, they refused. In short, I cannot recommend this company. Poor work, poor customer service."

Basement Waterproofing questions, answered by experts

Underfloor insulation alone will not cause moisture and mold, but improper installation can. Although the purpose is to seal any drafts, your subfloor still needs ventilation. If you seal the area too tightly and prevent all airflow, this can cause moisture to get trapped. This moisture eventually leads to mold and—if your floors are wood—rotting.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.
