Why Filling Concrete Blocks or Core Pour/Core Fill Is So Important For Basement Foundations

Filling concrete block cores or block and fill foundation concrete pouring is a reliable and essential method for ensuring strong foundations due to the filling of your concrete block cores. When properly done, core pour concrete pouring can provide your basement or foundation with structural support that will last for many years.

What Is Core Pour Concrete Pouring?

Core pour concrete pouring is a method of pouring concrete in which the basement and foundation forms are filled at the same time. The concrete, or core, is poured into an encasement that creates an uninterrupted wall around the structure. This method ensures a Structurally Sound basement or foundation, as it eliminates any weak points that could occur from traditional pour methods, where different parts of the form are filled with dry mix concrete at different times.

Core Fill or Core Pour, also known as Masonry Grout, is a Type of Construction Material used to fill the cavities in concrete block or masonry walls. When it comes to basement foundation repair, core fill provides several benefits, including:

Improved structural stability: Core fill helps improve the structural stability of your foundation by filling any voids or gaps in the masonry walls. This helps prevent any further damage to the foundation, such as cracks or bulging.

Enhanced moisture resistance: Core fill is highly resistant to moisture, which makes it an ideal material to use in basements that are prone to leaks. By filling the voids with core fill, you can help prevent water from entering your basement through the foundation walls.

Increased insulation: Core fill provides an additional layer of insulation to your foundation walls. This helps to regulate the temperature inside your home, reducing your energy costs and keeping your home more comfortable.

Reduced noise transmission: Core fill can also help reduce noise transmission between floors. By filling the voids in the masonry walls with core fill, you can help dampen any noise that would normally be transmitted through the walls.

Overall, core fill or core pour can be an effective solution for repairing a leaking basement foundation, as well as improving the overall structural integrity, insulation, and soundproofing of your home. However, it’s important to work with a professional contractor to ensure that the core fill is installed correctly and that the repairs are done properly to prevent any further damage to your foundation. We are pleased to provide our foundation core fill/core pour services in: Cobourg, Port Hope, Campbellford, Kingston, Belleville, Grafton, Colborne, Cramahe, Brighton, Trenton, Quinte West, Peterborough, Kawartha Lakes and surrounding areas.

Filling your Foundation Block Cavity with Concrete


Core Pour serves to strengthen your basement foundation.

Core Pour is a type of structural repair for cement block foundations, also known as cell fill, masonry block fill, mortar pumping or grout pumping.

It is a calculated mixture of cementitious and aggregate material used to fill cinder blocks, used to provide stability to a block wall. This process can be used in new block walls to add strength or can be used during a repair process to strengthen weak or compromised foundation walls.

Core Pour step 2 - holes are filled with concrete

The holes is then carefully filled with concrete.

Core Pour step 3 - AR Fibers are mixed into the concrete

AR Fibers are mixed into the concrete to add strength and extra crack prevention.

Core Pour step 4 - concrete is vibrated through the blocks

Concrete is vibrated through the blocks to improve flow and remove air pockets. 

Core Pour step 5 - holes are patched with Hydraulic Cement

The holes are patched with Hydraulic Cement. The wall can be left as is or parged.

Where basement and foundation

Cracks And Leaks Can Occur

P

Tie rod holes in basement walls are created by the 5/8” rods used to hold the steel forms together during the original foundation pouring of your basement. After the concrete has cured, the rods are disassembled and when they are removed, holes are left that go straight through your foundation.

P

Problems can also occur if window wells were not properly fastened to the wall. During the winter, when the ground freezes and swells, it may eventually push the window well upwards causing the earth to flow underneath the well and into the drain.

Problems can also occur if window wells were not properly fastened to the wall. During the winter, when the ground freezes and swells, it may eventually push the window well upwards causing the earth to flow underneath the well and into the drain.

P
A beam pocket is a recessed space designed to hold the end of an intersecting beam in a concrete wall, a masonry wall, or a column. Beam pockets in exterior structures are often subject to water leakage.
P
Honeycomb is a rough and stony surface that appears on concrete when there are air voids between the course and the aggregate. This happens when insufficient fine material gets into the concrete mixture due to poor mixing or incorrect aggregate grading.
P
Between your sump pump and the discharge line, there’s a valve that opens and closes to let water out of the pump. If the valve isn’t working properly, it will send the water back into your home. This is one of the most common reasons that sump pumps collect standing water.
P
Mortar issues allow leaks to occur in two ways: in the space between the mortar and the brick or through the mortar itself. Bricks too can be the source of the leak, as they’re considered porous.
P

Cracks up to 25mm wide could be a sign of structural damage and should be inspected and repaired by a professional. Very severe – any crack above 25mm in width indicates serious structural damage and will need major repair work, which could include underpinning and rebuilding.

P
Sewer leaks under a basement floor often appear in homes built before the late 1970s. This is due to a characteristic of a material found in older plumbing systems; cast iron.
P
Small to medium-sized cracks in your basement floor are natural and should not worry you. These do not indicate a larger problem. Cracks greater than 1/8 of an inch wide will require sealing with masonry and concrete-specific elastomeric caulking sealant.
P
Drainage issues around a home’s foundation, including poor grading, overflowing gutters, short downspouts, or clogged window wells can all cause water to pool near the foundation.

FREQUENTLY ASKED QUESTIONS

Basement Foundation Leaks & Cracks FAQ

Below you’ll find common foundation issues and how we fix them

PROBLEMS

Are cracks in house foundations common?

Cracks in poured concrete foundations are very common and are a natural result of the foundation settling. The concrete also tends to shrink slightly in the curing process. Most of the time minor cracks don’t present any problems but if the cracks get too large over time, they will allow water to penetrate your basement, and can be indicative of more serious structural problems.

Does every foundation crack leak?
No, but any crack that spans the entirety of your basement wall has the potential to leak. Even minor foundation cracks that don’t presently leak can leak in the future if they get worse. If a crack leaks once, it will certainly leak again in the future.
Are foundation cracks serious?
The good news is that most hairline cracks are not serious and can easily be repaired quickly and easily as long as they are only hairline cracks and don’t run horizontally or diagonally along your house foundation, or if the cracks are larger than 1/8″ or 3.175 millimetres. These are often a sign of structual issues that should be addressed immediately to prevent further damage and increase the total cost of the repairs.
What causes foundation cracks?

More often than not, there is no single factor that causes foundation cracks, but rather a combination of factors:

Movement or Settlement: all foundations settle or move over time as the earth below is compressed, shrinks or shifts. This is normal and the foundation usually settles uniformly as a whole. However if the settlement is uneven, it can cause serious cracks over time.

Soil Expansion: in certain areas, the soil contains more a high concentration of clay (also called absorptive clay) – this type of soil swells much more with moisture, and thus increases its volume significantly, causing enough pressure to cause the foundation to move or even crack.

Extreme Weather: very hot summers and extremely cold winters can cause larger than usual shifts in the ground. The cycles of very dry summers (where the ground shifts away from the foundation) coupled with unusually cold winters (where the ground freezes and expands) can put undue pressure on your house foundation. These repeated cycles of contraction and expansion can lead to cracks in your basement foundation.

Shrinkage During Curing: This happens early in the lifecycle of your home. If pourd concrete foundation dries too quicly, it can lead to small hairline cracks which coupled with the above factors can lead to larger cracks.

What if my basement is finished?
If you have drywall, wallpaper or panelling that you’re not eager to have removed, it’s often possible to have the foundation crack repaired from the outside.

SOLUTIONS

Can concrete foundations be repaired?
Yes they can! But before we start any repair, we have to know what caused the problem in the first place. Our expert estimators use state of the art thermal imaging systems that identify problematic areas that are invisible to the naked eye. We then do the necessary prep work, then proceed with a repair that solves your unique poured concrete foundation problems. If we don’t get to the root of it, the issue may reoccur.
Can concrete foundations be repaired?
We start by evaluating whether the damage is superficial or structural. We further ascertain whether the damage is local or widespread over a larger area. Then we check whether the supporting/reinforcing steel is corroded or damaged in any way. We also put our state of the art thermal imaging system to work to identify areas where heat may be escaping which could further be an indicator of deeper cracks that haven’t reached the surface yet.
Concrete crack injections
We can permanently fix your basement foundation leaks and cracks with low pressure crack injection using epoxy or polyurethane foam material. This method is highly cost effective and can be done quickly and with minimum disruption. First we install injection ports so that the epoxy or polyurethane can make its way into the crack. Then we seal the surface of the exposed crack using an epoxy adhesive. We then fill the crack with polyurethane foam or an epoxy, depending on the type of crack.
Interior waterproof basement wraps
We expose your foundation walls from the inside in order to repair any cracks, holes or other damage before installing a waterproof membrane and drainage system to keep the water, moisture, mold and mildew out of your basement.
Exterior waterproof basement wraps
We expose the foundation of your home from the outside, identify any cracks, holes, or other repairs that may be needed to stop water from leaking into your home. Once the necessary repairs are made, we will install a waterproof outside membrane that will not only protect your foundation, but also dissipate any water and divert it into a drainage system, ensuring your basement stays dry.

The guys from DoneRite have saved an old guy a lot of grief. Their work was fast and very clean, getting into and out of the basement, and keeping my shelves protected.

They were friendly, knowledgable. When on breaks, they helped me understand some of their work.

No more up and down stairs emptying buckets every day, and my sleep is peaceful now.

The DoneRite team was masterful, I highly recommended them!

We bought our home in 2015. It had waterproofing previously, but was limited, we had more work done years ago. The extra work was effective but not covering our whole house. Sadly, more leaks, and more complicated.

I tried to learn enough before they came to do an estimate. They provided a quote covering both outside and inside and explained a technique to connect both wraps I had not heard of when looking up waterproofing.

A window well filled with water, and then leaked, like Niagara Falls, in May.

The crew at DoneRite excavated and repaired a crack within a few days of my call.

You guys are amazing. Thank you!
