Exterior Waterproofing


Hydrostatic pressure can result in the structural damage of your home and can cause the entry of water into your property. Gaps and cracks in your walls and windows can also be entry points. Water affects different homes in different ways, depending on the environment and the foundations state.

PWS Waterproofing offers free consultation in which we will be able to evaluate your home’s condition and recommend the various solutions that are available. If we see that exterior waterproofing is the key solution for you, then we provide a full waterproofing service that will ensure the protection of the walls of your foundation including many other options that can restore your home to a dry, warm and comfortable state.


Exterior waterproofing procedure

The main exterior waterproofing solution that we provide is a waterproof jacket that is intended for your foundation. With the use of highly waterproof materials, we add extra layers of protection which will inhibit any water from getting into the exterior walls of your home. This is a permanent solution that will also maintain the structural integrity.

The procedure of exterior waterproofing involves the following:


The Process

Step 1:

We dig the area around your house all the way to the weeping tile pipe. The depth varies according to how elevated the building is, usually between 4 and 8 feet.

Step 2:

Next, we power blast and clean the wall. This exposes the brickwork or concrete that makes up your exterior wall. We then check for any structural cracks or gaps.

Step 3:

After the cracks are identified and the walls are exposed, we do the essential repairs to your foundations. Any defected areas are carved out and hydraulic cement is applied to any fissures. This expands and offers protection and restoration of your walls.

Step 4:

Next, aqua bloc is applied. This is a distinctive material that provides structural stability and is not so permeable. The stone is designed precisely to block the flow of water and adds a very effective layer of waterproofing to your house.

Step 5:

One layer of aqua bloc is usually not enough. We apply the yellow jacket which will firmly hold the material in place, and then another layer of aqua bloc is applied. This ensures dual protection such that no water ever reaches your exterior walls.

Step 6:

A membrane is applied as the final waterproof protection layer, and a complementary drainage system is installed. This ensures groundwater is directed away from your house thus reducing hydrostatic pressure, which ensures long term protection. This material relieves the pressure off the waterproof materials beneath and ensures the durability of the work. The drainage and membrane are then covered with a thick layer of gravel to make best use of the drainage.

Step 7:

The area is filled back to its original state and your garden is finally restored. Once we are done, you will never experience a damp problem ever again!

Other common exterior leak problems and solutions

For ultimate protection, your home may require additional services depending on the source of the leak or damp. Together with the provision of full waterproofing for the exterior walls of your foundations, at PWS we also use drainage systems and other procedures to ensure water does not come into your home in the first place. Some of the additional waterproofing services we provide include:


WINDOW WELLS

Water can collect in pools around basement windows and can seep through windowsills. In this case, PWS Waterproofing can install a new window well or modify it, which makes sure that rainwater falls beneath the windowsill and is then carried away from your house. Vertical weeping tiles can also be installed so as to waterproof the area that is exposed, and provide drainage and gravel so that your windows do not leak in the future.


FRENCH DRAINS

When water pushes against your house, structural problems and extra pressure may result, and when it collects in your yard, erosion results and your home will be in a mess. Having proper outdoor drainage systems is a very effective solution that makes sure ground and surface water is controlled and never left to gather in your compound or house. French drains are highly effective. These are drain pipe systems, which are modeled into your home. They are predominantly effective in homes that are surrounded by slopes thus accumulating more water.


GUTTERING SYSTEMS

Sometimes applying simple solutions can yield big results in your home. A broken guttering system that slopes and makes water pool in a certain area is very unattractive. Faulty gutters could sometimes be the source of dampness. At times, the solution is replacing your gutters or simply unblocking them. PWS Waterproofing can work to ensure your guttering systems are at their best and that water is kept away from your home.

Whenever you have issues of basement leaks, you want to make sure you get the best solutions. While there may various way to deal with the problem, exterior waterproofing solutions can go a long way in preventing water from entering your basement.

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.


Foundation Crack Repair

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.
