Construction that endures

Built on experience.
Made for what comes next.

Penna brings nearly seven decades of building experience to concrete systems shaped by the site, the plans, and the realities of construction.

What we build

Concrete expertise, applied with purpose.

01ICF Construction & InstallationWe install insulated concrete form walls, coordinating layout, reinforcing, openings, bracing, and concrete placement as one disciplined scope.
02Insuldeck Concrete Floors & RoofsWe plan and install Insuldeck floor and roof systems, including shoring, reinforcing, penetrations, edges, and concrete placement.
03Concrete FoundationsWe build concrete foundation scopes with close attention to layout, reinforcing, embeds, sequencing, and the structure above.
04Hillside FoundationsWe bring concrete and ICF experience to steep, constrained sites where access, staging, and sequencing are central to execution.

Built for the site

Built Around the Demands of Coastal Living

Penna coordinates structural work around terrain, access, reinforcing, openings, equipment, and jobsite realities.

ICF and concrete can contribute to resilience, but performance depends on the complete engineered assembly, detailing, site, and applicable requirements.

Our story and approach

Common questions

Planning Your Project

ICF uses stay-in-place forms for reinforced concrete walls. Installation includes layout, stacking, reinforcing, bracing, openings, and planned concrete placement.

ICF forms vertical walls. Insuldeck forms reinforced concrete floors and roofs. Each has distinct engineering and installation requirements.

Based in Dana Point, we serve the coastal cities from San Diego to Long Beach, with Altadena as an additional inland service area.

Share the project address, plans, structural and geotechnical documents, desired scope, schedule, and access constraints.

Start with qualified design and geotechnical professionals. Access, excavation, shoring, drainage, staging, and placement logistics matter.
