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.
