What is Basement Lowering?

Basement lowering (sometimes called basement underpinning) is the process of removing soil below a crawlspace or concrete slab, excavating the area to create a lower support level, and then adding new concrete footers, walls, and floors to extend the depth or reinforcing an unstable foundation.

This worthwhile home improvement is extensive and may damage your house’s foundation if not done correctly. It requires professional expertise in foundation walls, excavation, footings, and concrete floor replacement. Royal Work Corp. will carefully evaluate the foundation and surrounding area to determine job and building code requirements related to excavation depth, plumbing, electrical re-routing, and concrete work.

Our Professional Basement Lowering Process

All basement-lowering process involves excavating the soil of the original foundation of the house. However, there are two significant ways of excavating the foundation that is commonly used- They are underpinning and benching. Let us take a quick look at each of these processes:

Underpinning a Basement

Underpinning is a basement-lowering process in which the soil under the original foundation of your house is carefully removed. Like most basement-lowering techniques, the main aim of underpinning the basement is to increase its height. To do this, our workers carry out lots of excavation work using either conveyor belts or wheel barrels, depending on the access to the basement. The process is technical and has to be carried out by professionals who will ensure that the underpinning is done in a way that retains the house’s structural integrity while the process is ongoing.


Unlike Underpinning, Benching involves the process of excavating the soil around the original foundation of the house. In this case, workers dig about the place some foot down to the desired depth you want and then add a new concrete bench at an angle or slope to the old foundation of the house. This process does two things- It further reinforces the old foundation of your home with the new sloped concrete cast while also creating an additional room. Benching takes less time to complete and will cost you less money. However, if you want more space in your basement, there are better ways to go, as benching doesn’t create as much space as underpinning.

Process of Basement Lowering

The process of underpinning or basement lowering is done for several reasons: A homeowner may want to convert a crawl space or unfinished basement floor into a livable space, and the size or basement ceiling might be too small. A newly finished basement would require additional support, and the basement lowering process can give you extra space while underpinning can increase your load capacity.

Design Stage

With the initial evaluation complete and your goals established, you can bring in an engineer or an architect to design the new space. These experts will draw plans that detail moving and extending load-bearing walls required with this project. They will submit stamped drawings to the local municipality to obtain the necessary building permits before any work begins.

Basement Lowering Site Preperation

After plans are complete and the permits are issued, the engineers must prepare the site for construction. Furnace connections must be re-routed to move all ductwork and equipment out of the way. The next phase requires technicians to install temporary supports or vertical jacks to hold the home or commercial building in place while the underpinning is being done. Wooden boards or steel beams are used to disburse the structure’s weight and are removed once the project is complete.

Lowering the Basement

There are several methods for completing the lowering process, depending on the project’s purpose. The Traditional Mass method is used for shallow underpinning. In this instance, the soil underneath the foundation isn’t strong enough to support the home, and the weak soil is excavated and replaced with mass concrete.

This procedure provides both strength and a more efficient distribution of weight. The Beam and Base method utilizes the traditional mass base but incorporates concrete beams, and these are constructed underneath the concrete base to spread the load evenly for better support. A third method called Mini-piled underpinning allows the structure to rest on the stable ground 5 to 15 meters below the current footers. Piles are constructed and cased in steel, and the 15 cm to 30 cm piles are driven into pre-drilled holes to rest on more stable ground.

The fourth and more aesthetic purpose of basement underpinning requires removing the existing concrete floor. The soil is excavated in sections filled with concrete, and small gaps are left between the old and new concrete. Non-shrink grout is used to fill the area in each section.

Finishing the Job Right

Regardless of the basement underpinning type, once the process is completed, you can fix the old plumbing problems with new plumbing installed. Our experts will now install a waterproofing system to keep the area dry before adding a waterproofing membrane to prevent water infiltration from the outside.

The exposed foundation walls are then backfilled. It’s now time to waterproof the interior of the basement. An internal weeping tile system is placed around the entire perimeter of the room, below floor level. This drainage pipe will capture groundwater and re-route it to a newly installed sump pump that will safely discharge outside. A layer of gravel covers the entire floor area and will provide a secure base for the new concrete floor.

All the Advantages

Benefits of Basement Lowering

You can choose to carry out the basement lowering process for various reasons. Basement Lowering is a popular home renovation project that many homeowners undertake to increase the value of their homes. But there are many other benefits of the process, including the following:

Great Investment

Although there is a cost, basement underpinning might be essential and worth the investment. Things happen from time to time that cause the foundation to become less stable, and underpinning can help save your home.

Protect Against Flooding

There are many possible causes for this, including the natural deterioration of the foundation as a house age, as well as poor workmanship, damage from other repairs, climate change, soil change, and events such as a flood or an earthquake. You can save your basement against flooding.

Strengthen Foundation

The foundation of a building tends to suffer natural deterioration as the house ages, as well as poor artistry, damage from other repairs, climate change, soil change, and events such as a flood or an earthquake. You can save your basement against flooding.

Reduce Potential Issues

Basement Lowering is structurally safer than adding an addition to the house, which places additional strain on the foundation. These events may cause the foundation to shift, rendering it incapable of adequately supporting the house. With the basement lowering, you can avoid making your home more structurally unstable.

Add Living Space

Underpinning is used to increase the amount of living space on your property. It's increasingly used to obtain extra square footage, particularly in older homes.

Use Your Basement

Many older homes were never designed to utilize the basement for residential purposes. Basements were only used for storage, such as coal storage, oil tanks, or produce chill cellars. Basement lowering makes your basement more than just a storage facility but a cozy living space.

Create More Room

If you need more space but don't want to move, underpinning is an excellent option. Underpinning is a great choice to consider when looking for a way to add the additional room you require, and the potential uses for this extra space are virtually limitless.

Plenty of Options

You can use an underpinning basement for a spare bedroom, office, playroom, entertainment room, or in-law suite. Many homeowners are now using underpinning to build an apartment they can rent out as a secondary source of income.

Boost Value

Basement lowering is the process of excavating the space beneath an existing foundation and adding a new foundation at a lower elevation. Homeowners usually perform this procedure to create additional living space in a home, such as a basement suite. Basement underpinning boosts the value of your home and increases the amount of living space in your home.

All the answers you need to know about basement lowering

Let's Talk
How Much Does it Cost to Lower a Basement in Toronto?
Putting a specific price tag on lowering the basement can be very tricky, and this is because there are a lot of factors that can affect the cost of the process. Some of these factors include the space size, access to the site, soil, and the difficulty of excavation and landscaping. The technique employed is also essential in costing, as benching is less expensive than underpinning. However, on average, lowering the basement could cost between $35 and $70 per square foot.
Can a Basement Floor be Lowered?

The short answer is yes; you can lower your basement floor. However, it would be best if you considered many factors before deciding to lower your basement floor. You want to know the structural integrity of your house and the proximity of the house to your neighbors to avoid undermining their properties and risking damage payment.

How low and spacious you want your basement suite to be will also play a key role when deciding what technique to use. Fortunately, Royal Work Corp. provides free consultation and estimates, so you don't have to make guesses. You can get a professional opinion that would help you make a beneficial choice.

Can you lower a basement without underpinning?
Many assume that underpinning is the only way to lower their base, but this is not true. However, what do you intend to accomplish with basement lowering? There are two significant ways of lowering the basement- underpinning and benching. Underpinning involves installing piers or posts below the foundation footing to strengthen it. This process is more expensive but usually gives your room in your basement. Benching, on the other, involves creating extensions around the original foundation in a way that supports it. The process is cheaper and can be done faster. However, you would have less room with benching than with underpinning.
Is Basement Lowering the Same as Underpinning?
Many people use the terms Underpinning' and 'basement lowering' interchangeably, but they mean different things. Basement lowering refers to the general process of excavating the soil of your house's original apartment to make it structurally better and create more room. Underpinning is just one of two methods of lowering basements. Underpinning deepens the height of the basement and expands it vertically as well; hence many people prefer it to the benching method, which creates less room. This preference has contributed to underpinning being synonymous with basement lowering.
Can you Underpin a Finished Basement?
Sometimes you may need to lower the basement. The process can be done whether the basement is finished or still under construction. This method of basement lowering involves removing the existing basement footings, digging to a lower depth, and then pouring new footings at the new depth. The process has to be carried out in stages so the house doesn't collapse. You can underpin various basement types, whether the basement is under construction or finished. You can also carry out the process in different weather or any time of the year.
Is Benching Cheaper Than Underpinning?
Benching is a technique of lowering bases and holds several advantages to underpinning that can make them an appealing alternative. One of those advantages is cost. Benching doesn't require touching the foundation or original footing of the house, so it is not just less time-consuming, but it is also cheaper than underpinning. However, you should note that benching adds less space to the basement than underpinning. In some cases, benching can even reduce the usable square footage of the basement. Hence, if you want more space, you might be better off using the underpinning technique of basement-lowering.
What is the Difference Between Bench Pinning and Underpinning a Basement?
Bench pinning is another term for benching. Both benching and underpinning are techniques used to lower basements, create more room, and fortify the foundations of older buildings. The significant difference between bench pinning and underpinning is that bench pinning requires less digging, which makes it faster and cheaper to accomplish than underpinning. However, it comes with the disadvantage of reducing space as the basement will now have a new bench inside its inside perimeter.
