Dolphin Cove Multipurpose Building & Pavilion

Durable and Resilient Construction for Modern Coastal Park Facility

The Opportunity

Isla Blanca Park sits at the very southernmost tip of South Padre Island, Texas less than 10 miles from where the Rio Grande River empties into the Gulf of Mexico. The park is the most popular park destination in Cameron County with over 1 million visitors per year. Isla Blanca is a perennial "Top 10 Texas beach" according to USA Today. The Dolphin Cove multipurpose building and pavilion was designed to host theater art, music, school, and band concerts events to the area. The construction of Dolphin Cove was the first step in a multi-year renovation and expansion program for Isla Blanca Park.

Considering the public use of the building, salt exposure from the ocean, and the ongoing risk of hurricanes, the project team at Gignac Architects focused on balancing durability and resiliency with keeping the project within budget.

Key Design Features

The Bautex Wall System was selected for all of the exterior walls of the building with the exception of the large glass sections at the front. Bautex was also used on several interior walls to provide additional structural capacity for the building. The walls were coated with the Bautex Air and Moisture Barrier and then finished with StuccoMax Exterior Wall Finish and paint.

  • Bautex walls are the primary load bearing system for the building.
  • Two of the interior Bautex walls were designed and built to create moment frames that provide the entire lateral (shear) resistance for the structure.
  • Designed and constructed for highest wind zone (Seaward).
  • Solid monolithic walls without organic materials or wall cavities prevents moisture and mold problems in this hot-humid climate.
  • Abuse-resistant magnesium-oxide cement based stucco finish system for impact resistance and long term durability in hash environment.


Fast Construction
Using the Bautex Wall System accelerated construction by allowing a single contractor to build the structural walls in one mobilization.

Structural Simplicity
Bautex was able to provide all of the structural requirements for the building which simplified both design and construction.

Energy Efficiency
Continuous insulation, thermal mass, and tighter building envelope resulting in long-term energy savings.

Durability & Low Maintenance
Resilient materials that are mold-resistant, low-maintenance, storm-safe and 4-hour fire rated protect this important community asset.



Bautex proved to be the most cost-effective and fastest way to build the Dolphin Cove building considering the harsh coastal environments and the county's desire for a long service life. Specifying Bautex simplified the architectural design and allowed the structural engineer to fully rely on the wall system to achieve the loadings required for the project. Dolphin Cove is the first of several buildings in Isla Blanca Park that are utilizing the Bautex Wall System.
