Use this SimpleSpecs 3-part specification template to specify tilt-up concrete. Site-cast concrete panels that are cast horizontally, either on the building’s floor slab or a separate casting slab, and then lifted into final position.
What is it?
Tilt-up concrete panels are structural concrete members that are precast on-site rather than in an off-site facility. These panels can be poured on the building’s concrete floor slab on grade or on a concrete casting slab prepared specifically for this purpose. Panels may be insulated or non-insulated to suit project conditions. A wide variety of finishes are available depending on the expertise of the fabricator.
Reveals and rustications can be cast into the panels by placing wood strips on the casting surface. If the building’s concrete floor slab is used for the casting surface, and if floor sealers or applied floor finishes are desired, form release agents formulated specifically for this purpose must be used to allow sealers to penetrate and to prevent loss of adhesion of the floor finishes.
Tilt-up concrete is a construction technique that has been gaining popularity in recent years due to its many benefits. It involves casting concrete walls on a horizontal surface and then tilting them up into place using a crane. Once the walls are in place, they are secured to the foundation and to each other to create a solid structure. In this blog post, we will explore the advantages and disadvantages of tilt-up concrete, as well as its applications and construction process.
Speed: Because the walls are cast on a horizontal surface and then tilted up into place, the process can be completed quickly. This can result in significant time savings compared to traditional construction methods.
Cost: The use of precast concrete walls reduces the need for on-site formwork and reduces the amount of time required for construction. This can result in cost savings for the project.
Durability: The walls are made of solid concrete and are reinforced with steel, which makes them resistant to damage from weather, fire, and other hazards. This can result in a longer lifespan for the building.
Energy Efficiency: Tilt-up concrete walls have excellent thermal mass properties. This means they can absorb and store heat, which can help to reduce energy costs for the building’s HVAC system. In addition, tilt-up concrete walls can be insulated to further improve energy efficiency.
Site Requirements: Requires a large, flat site for casting the walls. This can be challenging in areas with limited space or uneven terrain.
Cranes: Requires the use of cranes to lift and tilt the walls into place. This can be costly, and the site must be accessible to large cranes.
Design Limitations: Limited in terms of architectural design. Because the walls are cast on a flat surface, they can only be made in flat panels, which may not allow for complex shapes or curves.
Industrial Buildings: Commonly used for industrial buildings such as warehouses, distribution centers, and manufacturing facilities.
Retail Buildings: Tilt-up concrete is also used for retail buildings such as big-box stores and shopping centers.
Educational Buildings: Tilt-up concrete can be used for educational buildings such as schools and universities.
Site Preparation: The site is prepared by leveling and compacting the ground.
Wall Casting: Concrete panels are cast on a horizontal surface using formwork.
Finishing: Once the concrete has cured, the panels are finished with any desired texture or color.
Lifting: Lifted into place using a crane and tilted into position.
Connection: Connected to each other and to the foundation using bolts or welding.
Roof and Floor Installation: Once the walls are in place, the roof and floors are installed to complete the structure.
