When it comes to wet basements, the root of the problem is typically located outside of the home.
So when it’s time to waterproof your basement, it is important to look outside of your basement walls. Exterior waterproofing is usually a much larger task; and it is a good idea for you to consult professionals when thinking about the methods of the exterior waterproofing. Excavation of the soil surrounding the foundation of your home is required. And as you can imagine, this can be intensive process.
When discussing exterior waterproofing methods it is also very important to mention the roof draining systems and downspouts.
When they are properly installed, they direct rainwater away from the foundation of your home. However if not properly installed or even maintained; these systems may have the opposite effect. Clogged downspouts or gutters that drain to close to your foundation will drop water along the base of your home. So, make sure that you maintain your downspouts so they can be clean and free of debris in order to work properly. Make sure that you have appropriate downspouts, so they can direct water as far away as possible from your home.
External waterproofing starts with the excavation of the perimeter of the foundation of your house.
Moreover, excavating all around the house to the full depth of the foundation walls; and then installing a waterproof membrane with termination strip running down to weeping tile. The membrane will provide simple pathway for water to flow down to a weeping tile at the bottom of your foundation. From there, water will flow away from your foundation into sump pump pit or storm drainage.
The final goal is a dry internal environment in your basement. Walls in direct contact with earth can be subjected to hydro-static water pressure. You have to effectively deal with this to stop water entering your home. Complete external waterproofing system with an Delta MS membrane is the best alternative.
In turn to further protect your basement from water entrance, it is preferable for you to install a French drain also. French drain is laid around the perimeter of the basement at a slab level; and can redirect surface water away from your property.
Basically, you have a trench around the perimeter; which contains a perforated pipe that is covered with gravel or crushed stone. When water hits the external surface, it will run down the membrane and then pass through the gravel. From here is then carefully removed to a soak away, sump chamber or main drain.
The Sump Pump System and also a Dual Pump System is designed for removing ground water from Delta MS membrane systems. Systems must include a check valve and also a battery-backup in case of power outrage.
Changes to floor, ceilings or walls.
Many of us take the structural elements of our homes for granted. In no doubt, we can clean them, but just how often do we actually look at them? And even if we do, we may not really observe the slow changes.
Noticeable Mold or Stains
Mold and stains is another possible sign of water damage. Stains frequently develop if there is a slow, steady leak.Mold can appear if areas are consistently damp; and can cause respiratory problems after expanded exposure.
Mold will not grow without the presence of moisture.
So, unless you have a high natural relative humidity in the house, you can presume there is a plumbing leak or water seeping in from outdoors somewhere.
Fungus growing bacteria or even mushrooms growing in your basement
A leaky basement can dock surprising amounts of bacteria increase and no anti-bacterial cleaner will be capable to clear it. Floorboards and also damp wall boards are most perfect place for these microorganisms to develop. These bacteria may cause chronic irritation issues, eye, nose and throat for people suffering from allergies.
The most familiar cause of mushrooms growing in the basement is the presence of excess moisture. Moisture will cause wood and other particle to decompose, creating the ideal environment for the mushrooms to expand.
Musty odors are another one of the familiar signs you could have water damage. The smell is very similar to wet newspaper or cardboard; and is typically strongest around the area where the water is present.
Outdated Pipes and Plumbing Fixtures
Most pipes are not visible, so we may often take them for granted. Therefore, many will last a lifetime of the home, but connections, faucets, and valves are likely to wear out over time.
Cracks may be vertical, horizontal, diagonal or stair-stepped. Harsh pressure or structural damage is apparent by widening cracks.
Cracks in the walls of your basement are a indicator that the foundation under your home is beginning to fall apart. This is causing many headaches for a homeowner like: ceiling and wall collapse, bowing walls, more cracks, sagging ceilings and more.
Usually they are caused by hydro-static pressure. Walls come out to be bowed inward.
If you are a home-buyer, real estate home examination will tell whether your future home has efflorescence.
Wet basement, particularly, are the ideal environment for efflorescence to grow.
Efflorescence is a crystalline dump of salts frequently seen on the surface of brick, concrete or natural stone surfaces. It can occur when water leaves salt deposits and is present on or even in the masonry surface.
Areas on walls where the paint is starting to peel are a headache-inducing view for homeowners.
Water seeping through walls may lead to peeling paint along the basement walls.
In fact, now and then a foundation wall just leaks. For instance, a poured concrete foundation wall can have porous spots in the concrete caused during construction; the concrete is not carefully mixed or by lacking vibration of the poured wall to remove trapped air. These porous spots will, over time, let water seep into the basement.
A common source of seepage in a masonry wall is a crack or weakening of mortar joints between masonry units. Mortar joints may crack because of slight foundation movement and worsen due to repeated movement or a defective installation. The typical wall will have hundreds of running feet of mortar joints; this means an enormous area of possible seepage problems.
Concrete block is especially vulnerable because water that seeps in through the outer side of the block can collect in the cavities and seep through the porous inner side.
In addition, foundation wall of any construction can have water seep over the top edge of the wall. Mainly if the lawn outside is sloping toward the house or if other bordering structures are build inappropriately.
For that reason, the cure for all of these problems is the same; installing an exterior waterproofing membrane to form a resistant water barrier on the outside of the foundation.
When installing an exterior waterproofing membrane the first step is to start digging. The foundation may be as deep as eight feet in a full basement.
The excavation should also be numerous feet wide to allow space for technicians to work. When the excavation is done, the setting up begins by cleaning the soil and loose mortar or concrete from the wall.
When the wall is out in the open, cleaned and dried, we do a careful exam to locate holes and cracks.
1. We chisel the crack with a hammer and masonry chisel to enlarge the base of the crack; and also to remove any loose material from the old concrete. The secret to fixing wide concrete cracks is to undercut the sides of the crack to give it a reversed “V” shape. This will help the restore material to “key” into the crack. Also will create a mechanical tie in addition to the chemical tie between the concrete and the patch material.
2. Then we eliminate all debris from the crack with power wash or with a metal brush.
3. Next we fill the crack up with hydraulic cement to restore the structural integrity of the wall and to avoid any further water infiltration.
4. Even the surface with the trowel.
5. Let the compound harden as directed.
6. The next step in the procedure is to apply a coat of Aqua Bloc® liquid membrane. It is best for poured and block foundation walls; and is the most cost effective and efficient technique of external waterproofing. Aqua Bloc® is rubberized asphalt hydro resistant material. We are applying it with a trowel to every inch of the foundation. It bridges holes and cracks for superior protection against the water access.
7. Next, we cover and reinforce the liquid membrane with a Yellow Jacket Mesh Fabric.
It protects and strengthens the applicable water-resistant membrane by sticking into the coating substance. The mesh is completely set into the Aqua Bloc® to hold it in place and to seal cracks and gap.
8. At last, we install the water barrier – the Delta MS Membrane.
The DELTA®-MS membrane is extruded and vacuum formed from high density polyethylene (HDPE) a durable, tough and non-toxic material. The membrane is amazingly resistant to water and water vapor, acids and other agents. The membrane installation is toward the wall to provide an air space which will allow any water to drain away from the foundation directly to the weeping tile. Molding strips along the top of the membrane help attach it to the wall and provide a firm seal.
9. Next, we are installing Weeping tile in order to provide a place for the water to flow. Modern technologies have created more efficient and stronger materials for weeping tile. We install a perforated plastic mode that is covered with a filter sock for preventing debris and sand from clogging the tile. For better protection and improved drainage, we are placing gravel around the tile. Around 10 inches of gravel is installed to increase the life expectation of the system.
10. Finally, the last step in the exterior basement waterproofing process is back-filling without damaging gas lines and underground utilities.
