Coming up with an average cost for foundation repair work can be quite difficult since there are so many factors that need to be considered. It all depends on the extent of work that needs to be done, as well as the type of foundation, the soil, the repair method used, your location, accessibility and the time and labour involved. For instance, a minor job could cost as little as a few hundred dollars while major repair work may run as high as tens of thousands.

Here in Toronto, we repair all types of foundations.  Some are easy fixes, while others can be quite the engineering challenge.

Costs For Foundation Repairs

Some other foundation repair costs that need to be considered include hiring a structural engineer, obtaining soil reports and building permits, seismic work, slabjacking and pier costs. There could also be a few hidden obstacles in the way such as deep footings, old repairs, and tree roots etc. If you require foundation work on your property due to flooding or faulty plumbing, be sure to contact your insurance company to see what is and what isn’t covered under your policy.

When purchasing a new home, it’s recommended that you hire a home inspector to see if there are any problems that need to be dealt with. If there are, you can simply walk away from the deal. However, if you already own the home and a problem arises you’ll need to repair it. When you come across a foundation issue it’s certainly better to rectify it sooner rather than later so it doesn’t become worse, unsafe and lead to irreparable damage.

In some cases, major repairs which need the use of hydraulic piers may cost an average of $10,000 or more, while minor cracks that only require crack filler may be fixed for an average of $500. However, the average repair often comes somewhere between the two prices. Two of the most common methods for foundation problems involve piering or slabjacking. When piering is used it means supports are placed underground to support and lift the concrete. This means the contractor needs to dig several feet down to make sure the pier is solidified. It’s then placed beneath the foundation and operated with hydraulics as it lifts foundation to where it should be and stabilizes it. Several piers are used and located at different locations under the home’s foundation.

When it comes to slabjacking, a mixture of grout is placed beneath the concrete foundation and it floats the foundation to where it should be. In general, the piering method is usually the most costly since excavation is required and the hydraulic piers have to be installed.

Underpinning or basement lowering, often includes lowering the floor, adding floor drains, a laundry room, insulation, stud wall partitions, waterproofing, reinforcing the foundation, and sometimes a basement walkout and the cost and time it takes will depend on exactly what work is being carried out.

You can dig a basement as deep as you please, but of course, more work is involved the deeper you go. if you’d like to go further than eight feet then the foundation walls may need to be reinforced. But before you get started, drawings and permits need to be taken care of. In general, the structural engineer will take care of these and obtaining permits may take as long as two weeks or even more. The cost of the permits will depend on the job’s linear footage and this will also include the drain and plumbing permits.

It’s also important that you take the time to find a properly-licensed contractor who is specifically insured for underpinning work since this particular job isn’t covered by the company’s general liability insurance. Be sure to view a copy of the insurance certificate and it should be for a minimum of $2 million. It should also include your name and address. When searching for a contractor, you may want to ask for references and to see a portfolio of their previous work.

During the underpinning process, there can sometimes be an unforeseen issue or two along the way, especially with an older house. If this is the case, it will typically add a bit of time to the project. A typical underpinning job will usually take four to six weeks to perform. However, this often doesn’t include the finishing work. Other factors that will influence the length of the job will include the specific conditions of the job and the engineering details.

For example, water lines or meters may need to be moved or installed as well as electrical panels, HVAC systems and basement stairs may need to be rebuilt or extended. Outside waterproofing is usually recommended as it offers better protection and that’s why it costs more than interior waterproofing. A backup sump pump system is also recommended for water removal in case of power failures.

Predicting the exact length of time for a basement underpinning project isn’t something that’s easy to do.

Cracks in foundation Toronto home

If you have a leaky basement you could solve the problem yourself if you’re handy or you may be better off seeking professional help. It will depend on what exactly the problem is and how complex the work is involved in repairing it. Of course, if you’re not able to pinpoint the source of the leaking water that’s probably an indicator that you should call a waterproofing contractor to find the root of the trouble. If you have small cracks in the foundation you may be able to plug them epoxy. But while this may help stop the water from entering the home it doesn’t solve the underlying problem. We have been repairing foundation cracks and water leaks in Toronto for over 30 years, While some things are minor and can be left alone or repaired yourself, other things can be an indicator of major problems and should be investigated.  Below are some situations in which you should probably call a waterproofing contractor.

Chronic Water Around Your Foundation

Water can accumulate around your home by pooling in the soil around its foundation. The soil then expands and can place pressure on foundation footings and walls. In turn, this can result in cracks. You should always make sure the downspouts and gutters are free of debris and in working properly. The soil around the home’s foundation should be properly graded by sloping at a minimum of six inches for each 10 horizontal feet. Many foundations have a drain system installed around the perimeter which is designed to move water below the surface away from the home’s foundation. This drainage system can sometimes get clogged and if t does you’ll need a professional contractor to unblock it.

Cracks in The Foundation

If the home’s foundation is cracked or has tipped, it will need to be reinforced to prevent it from deteriorating even more. The walls may be able to be repaired from the interior with steel braces, wood, wall anchors or carbon-fibre mesh. This will help prevent the foundation from any further shifting. As an alternative, the repair could involve the spreading of epoxy and then and using carbon-fibre mesh to make sure the wall is locked in place. If wall anchors are used they’re comparable to large bolts. Your yard will be excavated and metal plates are installed inside the foundation walls every six to eight feet. These plates use steel rods to connect them and they will help to help straighten and stabilize the wall.

Water Entering The Foundation

If a part of the home’s foundation has been washed out you may want to seek help. Water can get inside a foundation’s perimeter via a drainage issue, a clogged gutter or a broken water pipe. The affected area may be shored up with concrete or by leveling the area. However, you may need to take out a part of the foundation and then re-pour and tie this new section to the old with epoxy and rebar. Since there are numerous reasons your basement may be leaking and need waterproofing you can save a lot of time, energy, and money by calling a professional foundation contractor to find where the problem lies and what the most effective and least-expensive solution will be.

If you’ve called in a professional foundation company it’s a good idea to ask for a written report which lists the specific problem your facing as well as the options which can be used to repair it. You should also ask the contractor for the pros and cons associated with each of the repair methods.

Concrete Block Wall Basement in Toronto

Many homes in Toronto and the surrounding GTA have poured-concrete foundations, but some of them are made of concrete block, which is often referred to as concrete masonry units (CMUs) or cinder blocks. The walls of concrete block foundations sit on a footing which is a concrete-poured pad that is wider than the building’s foundation wall. This helps to distribute the home’s weight load. The foundation’s construction starts with pouring the footing inside a trench which contains metal or wood forms. The footing needs to sit lower than the freeze line and possibly deeper if there’s going to be a full-height basement.


Foundation Footings

The footing’s thickness and width depends on the construction and size of the home as well as the soil’s load-bearing capacity. During the basement excavation, the first row of concrete block is laid on the footing when it has cured to describe the structure’s perimeter. For foundation walls, the typical thickness of the concrete block is eight inches. However, foot-thick blocks are sometimes used for heavier loads and higher walls. More courses of block and mortar are added in a brick-like pattern until the proper height is reached. At this time, any openings and windows are built and the mortar in the wall is given time to  cure.

If there are hollow cores in the block walls they may be filled completely with mortar, but usually the edges of openings and corners of the wall are filled. In addition, extra strength may be added with steel rebar. Once the walls are finished the basement floor is poured with concrete and the ground floor framing is completed. The foundation is now supported at the bottom and top and it’s backfilled and compacted with soil while construction begins above the ground.


Fixing a Leak in a Concrete Block Foundation

Poured-concrete and concrete block foundations both have identical load-bearing strength, but concrete block walls are more susceptible to any type of lateral pressure which can result in seepage problems. This is because water can seep into a basement through concrete block walls via the porous blocks and any cracked mortar joints. It’s recommended that you waterproof a home’s block foundation by installing a waterproofing membrane to the exterior. This method can be done while the building is being constructed or by excavating around it.

The exterior membrane consists of asphalt-modified polyurethane. It’s applied in a thick coating to the exterior of the foundation walls and it created a barrier which helps keep out water. The waterproofing membrane is different than a damp-proofing spray as the spray is a thinner liquid which is sprayed over foundation walls when the home is built to keep condensation out of its interior. The membrane can be improved with exterior drain tile when the water table is high. The drain tile is designed to carry ground water away. In addition, drainage board can be installed on the walls as a method to help protect the exterior membrane by channeling the water downward.

If you don’t have the option of exterior waterproofing, then interior drain tile can help keep a block wall from allowing water through it. This often sees the installation of a vapor barrier on the inside walls which transports any water to the drain tile. This can be kept from view as a finish wall can cover the vapor barrier.

No matter what the reason is for your damp basement, if you have a concrete block foundation that needs to be waterproofed please feel free to contact our team of professional contractors at Nusite. We have over 30 years of experience dealing with concrete block walls in the GTA and will gladly schedule a visit to your home for a free inspection and estimate.


Finished Basement After Digging out Basement

Digging out a basement can be an ideal way to add some room or living space to your home and can often be less expensive than adding room by going upward or outward. The best option can be chosen after considering a few factors such as design, feasibility, function, and the cost.

If you intend on adding a finished basement to your dwelling you’ll also need to consider the stability and safety precautions since they’re different underground when compared to other floors of the home. And you also have to ensure that your basement is fully waterproofed and damp free before finishing your basement.

Starting Basement Dig Out Process - Underpinning

If your home already has a basement with decent ceiling height, then digging it out will be relatively inexpensive compared to starting from scratch. Once you have to start digging down several feet or lift the home to add a basement the cost will generally be comparable to adding a ground-level addition to the home. In general, a basement needs about a seven to eight-foot ceiling along with footing drains and foundation walls. If you currently have a basement with the ceiling height lower than seven feet then a digging will usually need to be done

Concrete and dirt will need to be removed when digging a few feet down and the existing concrete footings will need new ones made below them. In addition, a new concrete slab floor will need to be poured. If the home just has crawl space or the existing foundation isn’t adequate enough, then the house may need to be lifted to pour the slab and foundation walls. You’ll be able to install some form of insulation under a new concrete slab to improve the energy efficiency of the area. The new slab will enable you to place radiant heat tubes in the concrete to help heat the basement. Radiant heat could also be used for the entire home if you choose and it could result in more ceiling height if the old ductwork is removed.

Basement is Dug Out of Toronto Home

An egress, which is basically an emergency exit, should also be created. The local building codes will determine exactly where and how big the egress should be. In many cases, a large window that has a low sill is adequate since people can climb out of it of needed. A door can also be used as an egress which means a new door will need to be installed if the house sits on a sloped lot or a concrete stairwell will need to be dug. The question of connecting to the sewer line also needs to be answered when digging out a basement. If you know how deep the line is you’ll know if the basement can be drained by gravity or if water will need to be pushed upwards with a pump.

Another thing you need to consider is how much light will there be in your basement. If you’re using a window as an egress then the light will be fine in that specific area. But you may prefer adding more windows for additional light and/or a more open feeling in the room as well as glass exterior and/or interior doors. Homes with an existing basement will likely already have exterior or interior stairs for access to it. However, you typically have the option if relocating them if you choose as you may be able to free up some extra space by doing so.

Framing of Basement in Toronto After Being Dug Out

If digging out the basement sounds like the ideal way to add living space to your home, it’s imperative that the area is dry. Some basements have a history of flooding or being wet and damp and this would need to be resolved first. For instance, two inches of rain running off the roof of a 2,000 square-foot house can produce more than 2,000 gallons of water. To help solve flooding in a basement, it’s important there are no cracks in the foundation, the gutters aren’t clogged, and the ground doesn’t slope towards the home.

Finishing a walkout basement in Toronto

There are several solutions to a wet basement such as excavating around the home’s perimeter as well as installing drains along the inside of basement walls.
