The process begins by reviewing a blueprint and assessing the needs of the customer. The customers’ specifications are drawn and approved before an agreement is drafted. Upon approval of the detailed drawing, an agreement is signed, and a deposit will secure a position on the production schedule.
The approved drawing is divided into sections representing individual precast concrete wall panels and forwarded to the production team. Members of the production team prepare forms for each panel based on the production drawing. The appropriate concrete forms are selected and configured to meet the job specifications. Forms are configured for straight and corner panels, to provide openings for windows and doors, to produce beam pockets and to incorporate brick ledges. Structural components are subsequently added to provide the exceptional strength of the product. Concrete is poured into each form and finished with a textured broom finish. Once a form is poured and finished, adequate time is allotted for the concrete to cure.
The buyer is responsible for preparing the site to specifications listed in the Procedures Manual. The procedures manual is provided by Specialty Precast Company, Inc. and reviewed with each customer to ensure the customer has an understanding of the procedures for site preparation, bracing and backfilling. Final inspection and surface preparation will be done by members of the Specialty Precast Company, Inc’s installation team. With the site prepared, the installation of the precast concrete wall panels can be initiated.
The other component of a precast concrete wall panels foundation system is the installation of the wall panels. The installation processes can be simplified into two steps; preparing the site and erecting the panels. Installation requires the use of a crane and the services of a freight carrier to deliver the panels from the plant to the installation site. The crane lifts the panels from the truck and positions the panels at the installation site as members of the installation team guide each section into position. Panels are sealed with two layers of a butyl rubber material and fastened together using 3/4” bolts. Once the units are secured and checked for precise fit, the exterior is sealed with a polyurethane sealant, and the installation process is complete. The entire installation process is usually accomplished in a few hours rather than a few days.
