"Alex responded quickly with an estimate of most of the work. I added the blind and one faucet later. I asked him to supply two or three references and he e-mailed me four. All of the references gave him glowing reports. When he started he immediately showed he knew what he was doing. Everything was done well and came in at the exact price quoted. He cleaned up after the job was done and was very professional throughout the process. I would definitely use him again."

Basement Waterproofing questions, answered by experts

External pressure on the basement wall can cause it to bow inward. Soil, heavy with water saturation, is commonly the main culprit. The soil exerts immense pressure on the wall, causing it to fail, at least partially. This is known as hydrostatic pressure—these situations can occur after rainfall or simply due to regular groundwater presence and may be temporary or more permanent.  

Water damage to concrete is often gradual and can take months, if not years, for a concrete structure to be fully destroyed. The process often starts with cracks on the surface, followed by sinking slabs and eventually crumbling cement. Therefore, it is important to repair minor damages early to prevent the situation from worsening.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

The most flood-resistant materials you can count on in a flood scenario are concrete, closed-cell insulation, foam insulation (also known as expandable foam), pressure-treated wood, marine-grade plywood, and ceramic tile. When a material is flood-resistant, it can withstand direct contact with floodwater for at least 72 hours without being significantly damaged.
