Project Update: Meyerland Convenience Store

Responding to Hurricane Harvey with Flood Resistant Walls

It has been just over 10 months since Hurricane Harvey hit the Texas Gulf Coast and dumped epic amounts of rain on Houston. Parts of the city saw more than 50 inches of rainfall, with close to one-third of the city flooded.

Building owners have suffered since then, with extensive damage to their struc­tures, inventory, and business because of these flooding events. The archi­tec­tur­al and engi­neer­ing design community has been hard at work looking for and designing solutions to avoid or to mitigate damages caused by this type of disaster.

But not every building or structure can be moved or elevated for flood pro­tec­tion. Con­ve­nience stores and gas stations are next to impos­si­ble to elevate given the con­nec­tion with the vehicles and customers they serve. So how does one remodel a con­ve­nience store so that it’s ade­quate­ly protected and flood-resistant?

Choosing the Best Flood-Resistant Wall Assembly

Designers with Method Archi­tec­ture were con­tract­ed for the remodel and redesign of a con­ve­nience store in Meyerland, TX that sustained flood damage during Hurricane Harvey.

The walls of the store needed replace­ment, after Harvey’s flooding left the structure damaged and con­t­a­m­i­nat­ed with black water. The structure required a more durable and flood-resistant wall assembly, so the owners could reopen for business as quickly as possible and prepare for any future flooding events. The store owner and design team also wanted to keep as much of the existing building as possible to limit cost and waste.

The team at Method reached out to Bautex for assis­tance designing a flood resistant wall assembly using Bautex Block and Bautex Air and Moisture Barrier (Bautex AMB). The concrete structure of the Bautex Wall System is much stronger and more durable than metal or wood framing, and will give the store owner a hurricane- and flood-resistant solution to construction.

Steps to Building a Flood-Resistant Structure

In this build, the con­trac­tor will remove all of the existing metal studs, sheathing, sheetrock, and insu­la­tion from the building, leaving just the struc­tur­al steel frame and the roof system.

Bautex Block is simple to work with and easily mod­i­fi­able, allowing the con­trac­tor to integrate the Bautex wall into the existing steel structure. To begin the Bautex wall instal­la­tion, rebar dowel rein­forc­ing bars will be drilled and set into the existing concrete foun­da­tion to create the con­nec­tion with the Bautex walls.

Once the con­trac­tor has stacked up the Bautex Block and installed the rebar both hor­i­zon­tal­ly and ver­ti­cal­ly, concrete will be poured into the grid wall system. The Bautex Block and struc­tur­al concrete will serve as the basis for the flood resistant wall assembly. In this case, the walls will be built up to 40-inches to stay above the maximum flood elevation, and then tra­di­tion­al light gauge metal framing will be installed to infill the rest of the wall.

Once the Bautex Blocks are stacked and poured, the last step is the appli­ca­tion of the Bautex AMB fluid-applied air and moisture barrier. This creates a con­tin­u­ous water-resistant barrier to keep the walls dry in the event of a flood. This also makes cleaning up and san­i­tiz­ing after a flood incred­i­bly simple.

The con­trac­tor will seal the block to foun­da­tion joints on both the exterior and interior of the wall. The Bautex AMB will then be applied to the entire Bautex wall, interior and exterior as well as top of wall, while also extending down the face of the exterior foun­da­tion and onto the interior floor.

This design allows for quick and easy clean up after another flood. The Bautex AMB protects the structure, insu­la­tion, and enclosure from the toxic flood waters and can simply be washed down after the water recedes. The advan­tages to building flood resistant walls this way include speeding up the time it takes for the building to be reopened and mit­i­gat­ing the health hazards present with typical post-flood wall assemblies.

Rebuilding Texas Flood Zones With Confidence

With new Bautex walls, the remodel of the Meyerland con­ve­nience store will help get this small business back in operation sooner. If Texas sees more flooding this year and the store gets water inside, the clean up procedure will be dras­ti­cal­ly improved.

Thanks to the design team at Method and the Bautex Wall Assembly, the owner will have con­fi­dence that if another flood event happens his business will be protected for years to come.
