Do you live in Massachusetts and are considering building a deck? Well, you’ve come to the right place! In this blog, we’ll explore how deep deck footings must be when building in the Bay State. Let’s get started on understanding this important step for a successful home improvement project!
For a deck of footings, how many bags of concrete do I need?
The depth of the footings for a deck in Massachusetts depends on several factors, including the size and loading of your deck, soil conditions and frost depth. The building codes require that you build your deck on frost footings to prevent issues with frost heaving, which can cause the footings to come up out of the ground or cause uneven settlement over time. To determine how deep and how many bags of concrete you need for your deck risers or pier blocks, use this calculation: multiply the overall length and width of your project (in feet) by three then add two. The total number you get is the approximate number of bags needed for your project.
To ensure that your footings are located in a location not subject to frost heave, local building codes generally require that footing footings need to be dug at least twelve inches below existing grade. In addition, other requirements may state that they must reach a minimum depth before reaching undisturbed subgrade soils or even further before they’re fully below any seasonal frosts. If needed, it may be beneficial to have an experienced inspector review the footing depths before pouring concrete.
Is it necessary to have footings for a freestanding deck?
In Massachusetts, it is necessary to have footings for any freestanding deck which is greater than 18 inches in Elevation or 72 square feet or more in area. While the Massachusetts Uniform Statewide Building Code (USBC) does not require footings to be positioned below the frost line depth, the building code requires that they be placed at a minimum depth of 12 inches below grade.
The depth at which deck footings must be set is determined by a number of factors, including soil type and moisture level. The USBC also requires that deck footings meet or exceed their standard loading and bearing requirements. In some cases, deck footings may need to be deeper than 12 inches in order to support the load of the structure above it and provide adequate stability in unstable soil conditions. It is important to consult with a professional engineer or designer to determine the proper footing depth for your specific project and conditions.
For a deck, how many footings do I need?
When constructing a deck in Massachusetts, the footings must extend at least 12 inches below the surface of the ground and be placed in concrete. How many footings you need for your project will depend on the size and weight load of your deck. Generally, posts supporting beam sections should have three to four concrete footings, which should be spaced evenly around the perimeter, while posts that support rail sections should have two or three footings.
To ensure the stability of your deck over time, each footing needs to be no further than six feet apart with some exceptions in certain soil conditions or extra heavy loads. Additionally, all hardware and fasteners need to be corrosion resistant and in accordance with local building codes.
I’m not sure how I’m going to get a post into the ground without using concrete.
Installing deck footings properly is necessary for the long-term stability of the structure. The footings used in Massachusetts must be buried at least 2 feet below the finish grade of your yard (or below the frost line, whichever is deeper). This means that depending on the amount of soil on your property, you may need to dig much deeper than two feet to ensure a secure footing.
In order to avoid pouring concrete footings or using a post base installation device, there is an alternative method for installing deck footings which involves driving steel posts into the ground with a sledgehammer. This option requires posts that are cut off level at both ends and are embedded in 5-gallon buckets filled with concrete and rebar. However, this method doesn’t provide reliable stability and could cause problems later on as your deck becomes exposed to various weather conditions.
It’s best to use concrete footings when building any structure. If you do opt for hiring a professional concrete crew, they can pour stone or cement mix into deep holes prepared in advance, allowing them to pour footings quickly and easily without having to dig too deeply into your yard. Professionals typically include poured-in-place concrete forms during their work which allow for an even distribution of soil around the post, providing greater stability over time.
For safety reasons and to ensure stability, it is highly recommended that you rely on professional contractors when installing deck footings in Massachusetts rather than trying do it yourself or relying on an improper technique like cutting posts off level and placing them into buckets filled with concrete and rebar.
