Which type of foundation is stronger? How these two types of foundationslist are distinct from each other? These questions are usually coming from home buyers who seek answers to a stronger foundation that could enhance the durability and energy efficiency of their home.
When it comes to building a home, consideration of what type of foundation to be installed is taken into account. There are two types of foundations, which are the poured wall, and the precast foundation, that could make a home stronger, durable and energy efficient. And to guide you which kind of foundation is best for your modular home, let us consider a look at their comparison.
Poured wall system or the traditional foundation is most popular in America. It is a kind of foundation where efficiency is highly promoted. It is under a drainage system which is applauded for its superior performance. Poured wall is also by manufacturers to complete the basement instantly.
Traditional foundation is typically have a 2 inches concrete face which is poured against the insulated foam, and put between the outer face and 24 inches steel reinforced studs. It has a PSI of 3500 and as mentioned has a solid foundation to 24″ in the center, which do not require a stiffer mixture of cement.
Beneath the poured foundation are crushed rocks that allow balancing of the load to the footing. The crushed rocks below provide an excellent avenue for water drainage from the slab to the exterior tiles. However, build up of pressure is a big risk since the water has to circle around the footing to reach the tiles.
Poured wall costs are slightly higher than the insulated precast concrete. A study observed that labor fee add to the construction cost of poured walls because completion of this foundation is tedious and challenging.
Insulated Precast Foundation
Manufacturers have been included in the run to build a stronger and durable foundation for each home since then. Recently, they have engineered the insulated precast foundation, which they considered as their best answer. Providing proof to their theory, precast foundations have been established to modular homes and the result was amazing.
Precast foundation is completed quickly as it is made in a factory. Because no weather disturbances are holding the precast walls’ building process, it can be accomplished in one to two days depending in its dimension. They are pre- insulated and dries immediately. Even in the factory, precast concrete already has holes for plumbing and electrical system.
Manufacturers ensure superior quality of cement mix because no extra water is added while it is taken in the factory. It has at least 5000 PSI compared to the poured wall. This makes it sturdier.
Pea gravel is employed in precast concrete walls to achieve a superior quality drainage system. It hosts the water to flow to the footing through it. Because of its controlled joints attached to the panels, stress cracks are prevented, and move the water out through the sealant.
Insulated precast foundation cost is lower than the poured walls. This is ascribed to the savings made in the construction and labor costs. One big plus about this foundation is its 15 years limited warranty. This is more convenient than the poured walls as it does not possess one.
