Insulated precast foundation is manufactured in accordance to the National Standards and recognized Building Codes with 5,000 psi concrete. This eliminates the need for additional waterproofing.
Manufacturers of modular homes in Michigan guarantee that the insulated precast foundation prevents water infiltration and moisture build-up that causes structure destruction. Because of the insulated foundation, modular homes are warmer and drier than conventional houses. Additionally, there is a substantial increase in the value of living inside a modular home built over a precast foundation.
To further understand the waterproofing benefit of insulated precast foundation for the modular homes, let us look at how it is manufactured;
Anatomy of Insulated Precast Foundation for Modular Homes
To enhance strength and durability, insulated precast foundation panels are manufactured with steel-reinforced concrete studs, rigid insulation, a reinforced top and bottom bond (footer) beam, and a 2-inch-thick concrete facing.
The bond beams and concrete facing are cast in one continuous pour. They connect to the studs by encapsulating vertical re- bars and galvanized hooks and pins that protrude from the top, bottom, and back of each stud.
Pressure-treated furring strips are pre- attached to the inner face of each stud to provide a base to accommodate a variety of wall finishes. In addition 1-inch diameter holes are cast into each stud, allowing for the installation of wiring and plumbing.
The top bond beam is perforated with pre-formed 1/2-inch holes approximately every 24 inches to allow the bolting on of pressure-treated sill plates. The precast foundation system is delivered to the jobsite with a built-in footer and is installed on crushed stone sub-footer.
The precast foundation walls of modular homes are pre-insulated with 1-inch DOW Styrofoam, with an R-5 rating. Additional insulation may be added to the 7-1/2-inch-deep wall cavity between the studs to increase the R-value up to R-26. A triple bead of Bostik Chem-Caulk provides a watertight sealant at the panel seams. Set 12 inches from the precast wall, a 4-inch perforated drain pipe assures a drier basement by collecting and channeling excess water away from the foundation.
