Interior Wet Basement Solutions

There are several solutions that we can implement to ensure that your basement is dry and comfortable again. We modify the solution to suit your needs, and we use the following methods of interior waterproofing as outlined below.

Basement Wall Waterproofing

As the main type of interior solution, basement wall waterproofing delivers waterproof protection that inhibits mold and damp from getting inside your home. Delta membrane lets the water flow away from the walls instead of getting confined in one place. This is in combination with a sump pump and weeping tile drainage, which direct water away from your building to avoid a crisis. The process is further described below:


If damp or hydrostatic pressure has already caused destruction, we can repair any cracks and gaps evident in your foundation walls as well as ceilings. The cracks form the entry points of water. To repair the damages, we utlize hydraulic cement for the bigger cracks and good quality water-tight sealant where smaller gaps are spotted.


If water collects in one place, a simple drainage system is the best solution. Drainage systems drain water away from your building. When combined with basins and sump pumps, the drain directs the water to the water pump, which clears the water. This is normally called water control. We frequently use drainage systems combined with certain preventive measure like basement waterproofing.

A sump pump is an excellent system that gets rid of the excess water in your basement and pumps it outside, away from your property. We install sump pumps as a quick remedy for getting rid of water, or combine with full interior waterproofing services.

Full Interior Waterproofing Systems For Wet Basement

If you need more sophisticated repair to your building foundations plus a long lasting interior waterproofing solution that will ensure the full protection of your basement against damp, then the wet basement systems are the solution. We personalize the work to suit your home. This is a detailed overview of the procedure:

The Process

Step 1:

The floor around the edges that require waterproofing will be broken, and the concrete cleared. This enables us to dig on the interior. We ensure that the trench is not very deep, but allows us to cater for the weeping tiles.

Step 2:

We then drill holes in the walls. This allows the trapped water to safely drain away.

Step 3:

If there are cracks and gaps in your basement walls, they are repaired. In some instances, this only needs a water tight sealant. If you are repairing bigger cracks, we utilized hydraulic cement to help restore the walls and make sure no water can go through.


Step 4:

We apply a delta drainage membrane to the walls. This inhibits any damp, mold, or water from reaching inside your home and lets the water channel through the weeping tile drainage and to the sump pump systems.

Step 5:

Installation of weeping tiles is done. These are very good quality piping that will divert the flow of water away from your home.

Step 6:

The weeping tiles are constructed to lead to a sump basin, and a sump pump is installed. Once the system is active, the water will be directed to the pump, and then let to flow outside of your building and deposited elsewhere in a secure place.

Step 7:

We cover up the weeping tile with gravel to ensure maximum drainage.

Step 8:

We then pour concrete into the trench to an even level with the rest of the basement. We ensure that the area we worked on is thoroughly cleaned up and tidy, ready for use once again.


No matter what the source of your water troubles are, it’s important to properly diagnose the issue so that you can make the necessary fixes.

Weeping Tile | Sump Pumps | Backflow Valves

Weeping tile systems and sump pumps are parts of a drainage system designed to move excess groundwater away from your home. Older weeping tile systems should be examined for breakage or blockage and even replaced for maximum effectiveness. A mainline back-flow valve is highly recommended for new basement renovations as a preventative measure to keep your basement free of flooding and sewer back-ups.

Window Wells

If moisture is entering your home through a basement window you may need a drain installed in your window well so the water can’t pool.

When searching for a Basement Waterproofing Contractor it is always a good idea to understand what materials will be used to repair a leaking foundation crack in your cement wall. The industry standard is either Epoxy or Polyurethane expanding foam. What’s the difference? Let’s find out

Epoxy Foundation Crack Repair

Epoxy Foundation Repair is more well known out of the two options, but not always the best solution. Epoxy has a very thin texture, very close to water. The benefit of this it does very well in Hairline Foundation Crack Repair, due to having a low viscosity it is able to penetrate the crack very well and once it hardens it becomes harder than concrete. The disadvantages of Epoxy is more product is needed to fix a wider crack, and due to long cure times there is potential for the epoxy to drain out of the back side of the wall. Under certain circumstances, an Epoxy Foundation Crack Injection is a great way to structurally fix Foundation Cracks.

Polyurethane Foundation Crack Repairs

Do you have a Leaking Foundation Crack? If so, Polyurethane will become your best friend. For one, it reacts with water expanding and filling the Foundation Crack with in minutes. The set time for Polyurethane foam can be within minutes, which means the leak will be plugged and set by the time we leave your home.

Due to the expanding nature of Polyurethane it is preferred for larger cracks, which makes it more cost effective for both the Waterproofing contractor, and in return the customer.

We understand there can be a lot of choices when deciding how to fix a basement wall crack, and what material to use given the circumstances. Always talk to a local Waterproofing Contractor to find the right solution to your Leaking Foundation Crack.
