Determining what type of foundation to use is based upon the location, building & budget.  Recently in many of our single family residential projects we have been using a precast concrete foundation system called Superior Walls.  It’s very similar to modular homes in that it’s built off-site in a controlled environment, delivered by tractor trailer & then set in place with the use of a crane & set crew.  The walls are then bolted together at the top & bottom of each panel and then sealed at the joints with a one part polyurethane sealant designed specifically for precast concrete products. As you will see, the walls are custom designed for each project & come with cutouts for windows & doors.

Some benefits of using a Superior Walls system:

• DRY: using a special low water/cement ratio concrete that requires no additional dampproofing (See ESRs-1553 & 1662).
• WARM: with full-length insulation built in to increase energy efficiency.  Research indicates that over 33% of the heat loss through the basement occurs at the top 24 inches. That’s why Superior Walls foundations feature a continuous layer of insulation bonded directly to the concrete, resulting in high energy efficiency to help you reduce energy costs. 
• STRONG: 5000+ psi concrete is reinforced with steel rebar and polypropylene fibers for added strength and performance. The wall panels also feature convenient features like built-in accesses for wiring and stud facings for easy drywall installation with screws.  The purpose of any wall footing is to distribute the wall’s load over a sufficiently large area of soil so that the soil bearing capacity is not exceeded. Superior Walls utilizes a crushed stone footing to accomplish this. This properly prepared layer of clean crushed stone transfers the load from our wall system to the soil.  Superior Walls panels are bolted together at the top and the bottom of each panel and a one-part polyurethane sealant is used to seal the panel joints of the foundation system. This one-part polyurethane sealant is specifically manufactured for use with precast concrete products
• SPEED: A typical home foundation can be installed in less than one day. The walls can then be built upon or a modular home may be set on the walls immediately after installation.

Similar to the construction & setting of a modular home – a SW foundation saved the homeowner time & money. SW’s certified trained crew completed this foundation in one day.
