7 Things To Keep In Mind While Constructing A Basement

Considering adding a basement to your home? You might be taking it to be as simple as installing additional rooms for your home. It doesn’t, though. It might be challenging to build a basement, especially if you’ve never done it before. Hence, the following are some crucial things to keep in mind when constructing your basement to make sure that it’s done correctly and safely so you don’t end up with a wasted room.

Check The Foundation

Before you begin construction on your home’s new basement, check that your home has an adequate foundation. Basements are typically constructed as part of a complete home construction project. This means they are built with support beams and wooden planks, but before starting construction it is important to ensure that your foundation is structurally sound and able to support any additional weight added by a basement addition.

Height Of The Basement

To make sure your basement is fully functional, it’s important to build it at the right height. The basic rule of thumb for a finished basement is that the height should be about 7’6 high so people can move around more comfortably.

Leaks And Water Contamination Issues

Leaks and water contamination are the things that you want to avoid when constructing your basement. Leaks can cause structural damage and water contamination can cause mold. To prevent these issues, install a sump pump and waterproof your basement with an EPDM membrane.

Ventilation System

A proper ventilation system is one of the most important things you should consider when constructing your basement. Inadequate ventilation will cause mold and mildew, which can lead to structural issues as well as lead to bad smells. Installing one or more exhaust fans is also a smart option for these uses.

Emergency Escape Doors Or Areas

If you’re planning on living in your new basement, think about constructing proper emergency escape routes. Generally, your new bottom level should have at least two alternative exits. You should also make sure that each of these emergency exits is marked with large signs and glow-in-the-dark stickers so they can be easily identified during an emergency.

Installation Of Special Sewerage System

When planning and building your new basement, be sure not to overlook your sewer line. To prevent clogging or backups in your home’s main sewage line, you’ll want it to be functioning and properly linked. Moreover, hire a plumber if you need assistance with connecting them or getting them set up.


Whether you’re building a new, or remodeling an existing basement, waterproofing should be at least as much of a priority as insulating. Moisture can wreak havoc on your foundation and the house above it if not dealt with properly. If moisture gets into your basement walls, they will freeze when temperatures drop, leading to cracks and leaks that will only worsen over time.

The Bottom Line

Building a basement is not an easy task and many things can go wrong if you’re not careful. If you keep these things in mind while constructing a basement though, you should be able to avoid most of these pitfalls and have a functional and safe space for your family or guests.
