Four methods the New Jersey General Contractors & Builder Corp employs to prevent flooding in our new construction projects

Here are four methods the New Jersey Green Construction Board (NJGCB) employs to prevent flooding in our new construction projects:

Pour high tensile concrete wall Minimum 4000 PSI:

1. Strength and Durability: High-tensile concrete has a higher compressive strength than regular concrete. This means it can withstand greater loads and is less likely to crack under pressure. In a basement, where there may be soil pressure or water pressure against the walls, using high-strength concrete can help prevent cracks and leaks.
2. Reduced Permeability: High-strength concrete is typically less permeable than standard concrete. This characteristic is valuable in basement waterproofing because it reduces the likelihood of water infiltration through the concrete walls and floors. Less permeability means that water is less likely to seep through the material, keeping the interior space dry.
3. Crack Resistance: High tensile concrete is more resistant to cracking, which is essential for maintaining the integrity of the waterproofing system. Cracks in basement walls or floors can provide a pathway for water to enter. High-strength concrete is less prone to developing these cracks, making it a more reliable choice for waterproofing applications.
4. Structural Integrity: High-strength concrete is often used in load-bearing elements of a building. When used in basement construction, it can contribute to the overall structural integrity of the foundation. This ensures that the basement remains stable and waterproof over time.

Install  French drain:

NJGCB installed 2 French drains, one around the exterior footing of the house and the second installed under the concrete slab. This is a common approach to address water infiltration and drainage issues in basements and crawl spaces. Let’s explore these two types of French drains and their purposes:

1. Exterior French Drain: The exterior French drain is typically installed around the perimeter of the house, near the foundation walls. Purpose Its primary purpose is to redirect surface water, such as rainwater or groundwater, away from the foundation and basement walls. This helps prevent water from infiltrating the basement through the exterior walls.

2. Interior French Drain: The interior French drain is typically installed beneath the concrete slab.  Its primary purpose is to relieve the hydrostatic pressure under the concrete slab and send it to the sump pump. Also to prevent any cracks in the basement slab due to the water pressure

These two types of French drains work in tandem to manage both surface water and potential groundwater infiltration, ensuring that your basement remains dry and free from water damage. The collected water is often directed to a sump pump system, which then pumps it away from the house.

Install tough and dry waterproofing

A “Tough and Dry Waterproofing” system, as described, is designed to provide an additional layer of protection on top of a 4000 PSI concrete wall. This added layer aims to enhance the waterproofing of the basement and prevent any water penetration effectively. Here are the benefits and advantages of such a system:

1. Enhanced Waterproofing: By adding an extra layer to a high-strength concrete wall, you are reinforcing its ability to resist water penetration. This extra layer acts as an added barrier against moisture, making it even more challenging for water to seep through.
2. Minimized Water Intrusion: With the added protection, the risk of water intrusion into the basement is significantly reduced. This is particularly important in areas prone to heavy rainfall, flooding, or high water tables.
3. Reduced Maintenance: A reliable waterproofing system can reduce the need for ongoing maintenance and repairs due to water-related damage. This can save homeowners time and money in the long run.
4. Improved Indoor Air Quality: Preventing water infiltration can help maintain a dry and healthy indoor environment. This contributes to better indoor air quality and reduces the risk of mold and mildew growth.
5. Enhanced Structural Integrity: The added waterproofing layer can help maintain the structural integrity of the basement by preventing water-related deterioration of the concrete.
6. Peace of Mind: Knowing that your basement is well-protected from water intrusion can provide peace of mind for homeowners.

Install storm rain system:

A storm rainwater collection and management system, which connects roof leaders to underground pipes and directs water to storm pipes or seepage tanks, offers several benefits:

1. Effective Stormwater Management: Collecting and directing stormwater from roofs and paved surfaces helps manage excess rainwater effectively. This can prevent flooding and reduce the risk of soil erosion and property damage during heavy rainfall events.
2. Flood Prevention: By channeling stormwater away from the property’s immediate vicinity and into an underground system, this system reduces the risk of flooding in low-lying areas or basements.
