Cement Board Foam Wall Flood Remediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flood remediation methods for structures in flood-prone areas are costly, time-consuming, and emotionally burdensome, as they often require repeated demolition and reconstruction of walls, floors, and ceilings, using materials like drywall and fiberglass insulation that are easily damaged by floodwaters.
Innovation Solution
The use of cement board material combined with foam insulation to create resilient walls that allow water and debris to flow out during floods, while also facilitating airflow for drying, reducing the need for extensive demolition and reconstruction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If drywall and fiberglass insulation are used in wall construction, then the walls are easy to install and cost-effective, but the walls are easily destroyed and damaged by floodwaters requiring repeated demolition and reconstruction
Solution Approach 1:
The patent uses composite materials consisting of cement board combined with foam insulation to create walls that are both durable and flood-resistant. The cement board provides structural integrity and water resistance, while the foam insulation provides thermal insulation and additional protection against flood damage, resolving the contradiction between ease of installation and reliability against flood damage.
Solution Approach 2:
The patent changes the material parameters of the wall construction by replacing traditional drywall with cement board and fiberglass insulation with foam insulation. This parameter change transforms the wall from being vulnerable to flood damage into a resilient structure that can withstand flood events while maintaining insulation properties.
2Ease of manufacture
If traditional drywall walls are used, then initial construction costs are lower, but flood remediation costs and time requirements increase significantly due to repeated demolition and reconstruction
Solution Approach 1:
The patent applies preliminary action by incorporating flood-resistant materials (cement board and foam insulation) into the wall construction from the beginning. This preliminary preparation prevents damage during flood events, eliminating the need for repeated demolition and reconstruction, thereby reducing flood remediation time and costs while maintaining initial construction affordability.
3Reliability
If high powered fans and dehumidifiers are used for drying walls after flooding, then the drying process is effective, but the process is time consuming and financially burdensome
Solution Approach 1:
The patent utilizes the porous structure of cement board to facilitate natural drying processes. The porous nature of the cement board allows moisture to evaporate and air to circulate through the wall material, enabling effective drying without requiring high powered fans and dehumidifiers, thus reducing both time and financial burdens associated with the drying process.
4Reliability
If flood hardy building materials are used as suggested by FEMA, then resistance to moisture is improved, but the materials may still require repeated replacement and the process remains costly and emotionally burdensome
Solution Approach 1:
The patent employs composite materials with cement board and foam insulation that provide superior moisture resistance and structural durability. This composite construction creates a resilient wall system that withstands flood events without requiring repeated replacement, thereby reducing the complexity of reconstruction processes and alleviating the financial and emotional burdens associated with repeated rebuilding.

Function Achieved in This Case
This approach significantly reduces the costs and time associated with flood remediation, minimizes the need for repeated reconstruction, and helps alleviate the emotional and financial burdens on homeowners and businesses.
Implementation Method 1
allow water and debris from a flood event to flow out of the walls
Implementation Method 2
allow airflow to enter the wall to ventilate the inside of the wall

AI summary
An apparatus, structure, and method are disclosed for flood remediation of a residential or commercial structure. The flood remediation apparatus, structure, and method may include forming foam insulation in a certain shape within a wall and using modified cement boards instead of traditional drywall. Forming the foam insulation in a certain shape, such as the shape of a rut or cavity, will provide a channel to allow water from a flood event to flow out and air to flow into the interior of a wall. Using modified cement boards in place of drywall allows airflow to travel to the interior portion of the wall and is a more durable material that can be dried, cleaned, and reattached onto the wall once all interior surfaces that came in contact with flood waters are completely dried. In other embodiments, the cement boards may be left on the wall. In some embodiments, drying behind a cement board wall is facilitated with a portable fan blower adapter.
