NEXGEN MgO Water Resistance

This is important to know - almost 90% of all natural disasters are related to floods.

Whether caused by rain, snow, hurricanes, or broken pipes, water damage is the biggest risk to your home or business.

NEXGEN MgO building products are water resistant and can be used in situations that are going to experience water intrusion and moisture. 


Key Water Resistance Facts

Flood Insurance Claims

The average home insurance claim for water damage is $11,098. The average flood claim payout from the National Flood Insurance Program is $52,000.·

Millions are at Risk

14.6 million U.S. homes are at risk of flooding. On any given day, home water damage emergencies affect 14,000 people.

$20 Billion Annually

One inch of flood water can cause more than $25,000 in damage. Nationwide, household water damage costs up to $20 billion annually.

Case Study Summary


We want to mitigate damage from water intrusion, flooding, and moisture


Use MgO panels and boards in sheathing, floor and roof underlayment, and backer board applications


Homes and Commercial buildings are more resistant to water damage to reduce costs and increase building lifetimes.

What is Water Resistance?

A water resistant material like NEXGEN Mgo board repels the penetration of water to a substantial degree and significantly reduces destruction caused by exposure to liquid.  Water resistance differs from water proof which means impermeability to water no matter the time duration. 

What are the Water Resistance standards?

The ASTM C1185 supplies the standards for Flexural Strength due to water exposure and moisture content. ASTM C1186 supplies the standards for Moisture Movement and  Water Absorption.  ASTM C1396 covers Humidified Deflection. AC376 and ASTM E72 cover Wet Racking Shear. 

What are the best Water Resistance building techniques?

It is not surprising that building residential and commercial structures in such a way that floods do not cause structural damage involves using different types of water resistant materials.  These include concrete, closed cell insulation, bricks, tiles, aluminum, steel, and NEXGEN MgO boards instead of wood, drywall and plywood.
