Manufactured Home Service


Advantage Grading & Engineering offers manufactured and modular home site services from civil design and site improvement through occupancy.

Whether building a single manufactured or modular home or a multi-unit development, site preparation, permanent foundation, and professional home setup are absolutely necessary for maintaining the quality construction and durability of your manufactured or modular home.


The Manufactured Housing Institute  states that the failure to properly grade the site for drainage can cause water leaks into the home’s foundation. Unstable ground can also lead to potential home structural problems. Foundations inappropriate for terrain conditions can cause concerns as well.

In its most simplistic definition, a permanent foundation will generally consist of a skirting to keep out vermin and water, footings and piers to support the home from gravity loads (such as snow and live loads), anchorage to resist lateral loads such as high winds or an earthquake and other considerations.
