Why is precast better than other methods of construction?
Strength and value. Not only will you experience firsthand the tremendous cost savings of precast walls but precast foundations provide a stronger and safer structure that is installed in a fraction of the time required by other methods of construction. Value is realized by the cost savings associated with finishing the foundation into living space.
What makes Specialty Precast Foundations better than other Precast systems?
A monolithic pour and the product design. Our product is manufactured using one pour for a solid concrete panel where others use separate pours for the interior and exterior to accommodate insulation. Another feature is that every panel has a concrete stud on each end. Panels are joined by bolting through the studs to create a solid concrete column every eight to twelve feet. Exterior corners are poured using 45 degree angles to form an eleven inch solid, concrete post in each outside corner.
Why is a crushed limestone base preferred to a solid concrete footer?
In traditional construction, concrete walls are placed on a concrete footer and typically rely on a single exterior drain to manage water. The problem is that the single drain is either not adequate to handle the amount of water or the pipe loses efficiency over the years. The result is that water becomes trapped behind the wall creating hydrostatic pressure. Constant pressure on the exterior subsequently leads to dampness or water leakage inside the foundation. By using a crushed limestone base, hydrostatic pressure is eliminated since water can either dissipate through the stone trench around the perimeter, through the earth or is channeled away from the foundation by the interior and exterior drains. The other issue with concrete footers is the situation where forces from the earth cause the footer to crack which can cause cracks in traditional masonry structures. Isolating the structure with the crushed limestone base buffers the structure from movements in the earth.
How does the price compare to block?
The cost savings of precast walls depends on whether you are comparing the initial cost of precast to block or comparing the completed cost of a finished basement. Initially, the cost of a Precast foundation may be slightly higher than block. On the other hand, a precast foundation is prestudded and saves the additional time and material required to finish a masonry foundation.
What is the R-value?
Our insulated product consists of 8-1/2″ of EPS foam with an R-value exceeding R-30. By adding insulation to the interior, we are able to offer a fully insulated product without compromising the strength of the product.
How long does it take for a foundation to be delivered after the order is placed?
Wait time usually ranges between three and six weeks. Once we receive a signed drawing and agreement along with a 50% deposit, we secure a position in the production schedule. Wait time is dictated by the number of jobs on the production schedule.
What are the customer’s responsibilities?
Before we arrive, the customer is responsible for determining site conditions, excavating the site, installation of the drains, compaction of deep footings and marking the corner pins. After the installation, the customer will pour the concrete floor, brace the structure and backfill. Customer responsibilities are listed in the Procedures Manual and reviewed with a member of Specialty Precast Company, Inc.
What is the warranty?
A 15-year warranty against structural defects and damage is available.
