I am a newly started hardscape business owner with over a decade of experience. Looking to provide a great service and experience at the best cost possible. Our specialties are, but are not limited to Walkways, Patios, outdoor living spaces

"After meeting with multiple contractors, East Gate Hardscape was chosen as the contractor of choice for out patio/walkway project. Being budget sensitive i had concerns about the cost and viewed it as being "nice" to have but can we afford it ?? After talking with East Gate and their proposed price, that "nice" to have patio/walkway became reality. As the project ensued I was pleased as the homeowner to see the attention to detail and the care taken to get the job done right - seeing this I knew I made the right choice. We are very pleased with the final product and it didn't break the bank !!! East Gate comes "highly" recommended !!!"

Basement Waterproofing questions, answered by experts

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.

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.  

The only real negative when encapsulating a crawl space is that the cost is high. It can cost several thousands of dollars to do this project. However, it protects your house and those in it by providing an energy-efficient space instead of one that frequently pools moisture and causes damage through mold growth in your home. While less common, another disadvantage could be encapsulation making access to pipes and electrical slightly more complicated in certain crawl spaces.

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.

Overwatering can cause issues like water pooling and drainage problems. To prevent overwatering, monitor your soil levels on a regular basis and change your watering schedule as necessary.
