What Is Below Grade Construction?

February 19, 2023

Below grade in construction is a term that describes a space that is below ground level – typically referred to as a basement.



The term “below grade” is used in real estate to describe any space that is below ground level, such as a basement. The definition of a “below grade” space is also more specific than a “basement.”
It is important to understand what is below grade because it is a crucial part of building design and construction. Below grade structures can include anything from an underground storage area to a tunnel or even a vault, and waterproofing is critical in these areas.

Below-grade construction presents many challenges for architects, contractors and builders. These challenges range from varying site conditions and construction methods to the need for redundancy in below-grade protection. Fortunately, a robust below-grade barrier is an essential component to any building envelope and EPRO’s below-grade waterproofing and contaminant barrier systems offer the best in protection and constructability regardless of site conditions or construction methodology.

Furthermore, in places where the ground freezes, you must build the foundation to be deeper than the seasonal frost line.

Understanding Below Grade Construction

If you are in the construction industry, then you have no doubt heard of the term “below grade construction.” But what exactly does this mean? Below grade construction refers to any type of construction that is below ground level. It often involves building foundations, basements, and other structures that are either partially or completely underground. It’s important to understand the different types of below grade construction in order to ensure a successful project.

Types of Below Grade Construction

The most common type of below grade construction is foundation work. This involves creating a stable base for a structure by pouring concrete footings, installing rebar, and adding waterproofing materials such as tar paper or plastic sheeting. This type of work requires expert knowledge and experience since it must be done correctly in order to guarantee the stability of the structure above it.

Basement construction is another type of below grade construction. This involves excavating the area beneath a structure so that a basement can be created. This can involve digging down several feet and constructing walls, floors, and ceilings for the basement space before backfilling around them. It also requires waterproofing measures such as drainage systems and sump pumps to ensure that water doesn’t enter into the basement space after it has been constructed.

Finally, some projects may involve underground utilities installation such as sewage lines or electrical conduits. These require similarly careful excavation techniques in order to ensure they are properly installed without damaging existing infrastructure or causing safety issues with nearby structures.

Overall, below grade construction can be an important part of any project but it must be done correctly in order to ensure success. Make sure you hire experienced professionals who know how to handle these types of projects safely and effectively so that your project runs smoothly from start to finish! With proper planning and execution, you can make sure your project comes out looking great no matter what type of below grade work needs to be done!
