Precast concrete walls offer a compelling combination of speed, performance, and design versatility.
Unlike tilt-up or cast-in-pace concrete walls, precast wall panels are manufactured off-site in a controlled environment and then transported to the jobsite for installation.
Precast wall panels can be engineered to serve as structural, cladding, or freestanding wall systems. When used for structural or cladding applications, precast walls provide a thermally efficient building envelope that can reduce long-term energy and maintenance costs. Freestanding precast wall panels provide a visually appealing solution for perimeter protection in residential, commercial, and municipal environments.
Precast wall panels offer a range of advantages for project teams seeking efficiency, performance, and durability.
Precast wall panels are produced to the exact specifications of each project, including wall height, width, thickness, and placement of openings. At County Prestress & Precast, we produce insulated wall panels up to 15 feet wide and as tall as 55 feet.
Off-site production means precast panels can be produced in parallel with site prep and foundation work. Once delivered to the site, they are ready for immediate installation, with no need to make modifications to integrate with other building components. This helps to dramatically shorten the overall construction schedule, and can lead to earlier occupancy and a faster ROI for building owners.
Precast walls require less staging space than other concrete wall systems and do not involve on-site formwork or lengthy curing periods. This reduces site congestion, minimizes labor costs, reduces onsite waste, and shortens the overall construction schedule.
Precast wall panels can be engineered to withstand vehicle impact, high winds and windblown debris, fire, and blast loads. In addition to typical design requirements, precast wall panels can incorporate project-specific hardware and specialized connectors.
When working with precast wall panels, designers have a wide range of finish options. Panels can be customized during production with a wide variety of techniques to achieve virtually any aesthetic:
These options can enhance the curb appeal of large-scale buildings and help project teams meet specific branding or contextual requirements without additional exterior finishing work.
Concrete is a versatile building material that can be manufactured off-site or on-site, with each construction method offering different advantages that can help teams overcome project-specific challenges.
Precast panels are often manufactured in climate-controlled facilities, and they are quality-tested before shipment. At County Prestress & Precast, our PCI-certified production facilities are equipped to produce high volumes of quality products with short lead times to accommodate tight construction schedules.
Once delivered, precast wall panels are installed using cranes. Erection of precast panels typically can be done faster and with less labor than other concrete wall systems. Precast walls offer greater flexibility in terms of panel design and surface treatments. Additionally, precast wall panels can be manufactured as insulated wall panels offering an insulated thermal barrier between the inside and outside of the wall elements, which can boost the thermal performance of a building and lead to lower operating costs.
Tilt-up walls are cast on the ground horizontally on the jobsite and lifted into place after curing. This construction method eliminates transportation costs and provides design flexibility, but it requires multiple days for form setup and curing and is highly susceptible to weather delays. Insulation can be added to tilt-up panels, but it adds time and complexity to the curing process, which can lead to further construction delays. It also requires finished foundation work and a large staging area before wall construction can begin. Overall, tilt-up panels require significant on-site production time and complexity which significantly increases the duration of field operations.
With cast-in-place construction, wall elements are poured into formwork at their final location. Like tilt-up construction, site-cast concrete requires multiple days or weeks for form setup and curing. Weather disruptions and extended site disturbance can increase project duration and complexity.
Precast wall panels can be manufactured with a layer of insulation encased in two layers, or wythes, of high-strength concrete. Insulated wall panels offer all the benefits of other precast concrete walls along with enhanced thermal efficiency. The integrated insulation limits thermal bridging and helps maintain consistent indoor temperatures. In large-scale climate-controlled facilities, insulated wall panels can lead to reduced energy consumption.
Mechanical Integration
Openings for windows, pedestrian doors, dock doors, trailer restraints, and mechanical penetrations can be cast directly into the panels during production. This improves alignment with mechanical, electrical, and plumbing systems and reduces on-site modifications.
High Performance Building Envelope
High performance buildings incorporate the maximum level of design, construction, operation and maintenance principles to offer owners a greater return on investment than a conventional building. Insulated precast concrete wall panels are a high performance building envelope solution that offers strong thermal resistance, helping meet energy code requirements and reduce heating and cooling costs. Their low maintenance requirements and unmatched strength and durability also contribute to long-term cost savings.
Occupant Safety & Comfort
Concrete’s inherent fire resistance also enhances life safety and can reduce insurance premiums. Once installed, the panels require no additional fireproofing, drywalling, or insulating to achieve two-hour fire ratings. Building occupants also appreciate the high sound absorption of the panels as well as their ability to improve indoor air quality.
Adaptability for Future Expansion
Facilities that anticipate future growth benefit from the flexibility of precast systems. Panels can remain in serviceable condition for 60 to 100 years, and they can be removed, repositioned, or added to, allowing the structure to evolve with operational needs.
