Interior foundation waterproofing wraps, also known as waterproof membranes, are a type of waterproofing solution that can provide several benefits for your home, including:

Preventing water intrusion: Interior foundation waterproofing wraps are designed to prevent water from seeping into your basement through the foundation walls. By providing a barrier between the wall and the interior of your home, the waterproofing wrap can help prevent water damage, mold growth, and other issues caused by water intrusion.

Reducing humidity levels Water intrusion can also lead to increased humidity levels in your basement, which can promote mold growth and other moisture-related problems. By preventing water intrusion, interior foundation waterproofing wraps can help reduce humidity levels and improve the overall indoor air quality of your home.

Ease of installation: Interior foundation waterproofing wraps are relatively easy to install compared to other waterproofing solutions, such as exterior excavation. This means that you can have your basement waterproofed quickly and with minimal disruption to your daily routine.

Durability: Interior foundation waterproofing wraps are made from high-quality materials that are designed to withstand the harsh conditions of a basement environment. This means that they can provide long-lasting protection for your home, helping to prevent water intrusion and other moisture-related issues for years to come.

Improved property value A waterproofed basement can increase the value of your home, as it provides an additional layer of protection against water damage and other issues that can impact the structural integrity of your home.

Cost-effective solution: Internal waterproofing with membrane wraps is generally less expensive than external waterproofing methods since it does not require excavation and landscaping work to expose the exterior of the foundation walls.

Minimal disruption Internal waterproofing with membrane wraps is also less disruptive to your home and daily routine. The process can be completed relatively quickly and without the need for heavy equipment, which can be particularly advantageous if you need to continue living in your home during the waterproofing process.

Versatile application Internal waterproofing with membrane wraps can be used in a variety of foundation types, including poured concrete, masonry, and stone. The membrane can also be applied to both finished and unfinished basements.

Overall, interior foundation waterproofing wraps can provide several benefits for homeowners, including preventing water intrusion, reducing humidity levels, ease of installation, durability, and improved property value. If you are experiencing issues with water intrusion or high humidity levels in your basement, interior foundation waterproofing wraps may be an effective solution to consider.

Basement FOUNDATION Interior WATERPROOFING Membranes

What is an Interior Waterproof Basement Foundation Membrane or Wrap?

An interior waterproof basement foundation wrap is a specially designed layer of protection that helps prevent water from entering your basement. The waterproof wrap is installed on the inside walls of your basement, which creates a barrier against water infiltration. This barrier stops moisture from seeping into your walls and prevents mould growth.

The interior waterproof foundation wraps are made with an advanced technology that makes them very durable and resistant to deterioration. They are designed with high quality materials that are able to withstand harsh weather conditions like freezing temperatures and heavy rainfalls. These materials can also be used for many years without showing any signs of wear or tear.

In order to get the best results possible from your interior waterproof basement foundation wrap, it is important not just to install it correctly but also to maintain its quality once it has been installed. In order to do this, you will need to regularly inspect it for signs of wear and tear as well as any damage caused by insects or rodents such as rats or mice who may chew through parts of your foundation if left unchecked over time!

Some Of The Steps In

Waterproofing basement foundation walls from inside

Exposing the footer under the concrete floor
Interior waterproofing wraps begin by exposing the footer under the concrete floor, using a jackhammer on floor for about 12 inches.
Material removed from beside the wall footer
The material, typically gravel but sometimes dirt, (sometimes a second, earlier poured cement floor is found) is removed from beside the wall’s footer.
Trench beside the footer has a big-O weaping tile installed
The trench beside the footer has a big-O weaping tile installed with gravel, on a slight slope across the distance, to allow gravity draining to the sump pump. The remainder of the trench is filled with gravel, allowing water to pass easily to the big-O.
Floor is restored with new concrete over the gravel
The floor is restored with new concrete over the gravel. The new concrete is finished to blend with the existing floor as smoothly as possible.

We may apply an additional finishing on the concrete, depending on the existing floor, to be discussed with customer.

The completed interior wrap permanently seals the area, and redirects water out of the house.

Our waterproofing work is covered by a lifetime warranty, and we strive for high customer satisfaction.

Where basement and foundation

Cracks And Leaks Can Occur


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.


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.

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.
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.
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.
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.

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.

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.
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.
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.


Basement Foundation Leaks & Cracks FAQ

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


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.


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!
