Irene was gracious enough to flood our basement. We dont have a sump pump or anything similar. So we need to get that taken care of. I have had 3 companies come out to look at what we have. All prices are in the same ballpark. Either way it is going to get done, but i wanted to see if any of you have been through this. I don't mean to hijack this thread but I'm curious about the efficiency of french drains also.
In my area neighbor's saw their basements flooded several times in the past 5 years from severe storms, when they said they hadn't seen water there at all for the 25 years they had been in the house before then. Seems like the environment has changed.
We are planning on renovating our basement. We have not had water in the basement but I'm realizing that's not necessarily a guarantee for the future. We do get water in the garage, which is below the first floor of the house. Besides a french drain, what other preventions could be put in place?
Thank you. If the surrounding streets and yards are under a foot or more of water, I don't think interior weepers are going to be of much help. You'll fill up the sump and pump it where??
To the outside yard? To the overwhelmed city storm or combined sewers? If you have a continuing basement water problem, the solution is to stop the water before it breaches your walls. That means a membrane and exterior weepers. And even then you'll face the same problem if your whole neighbourhood is under standing water. And it's way too late to waterproof under the basement slab.
So you won't stop water from a rising water table. Sometimes Mother Nature doesn't take "No! Still sold on interior weepers--and those salesmen are convincing, I know--I don't see that it makes much difference where they put in their weepers.
As long as there's lots of gravel under the concrete to channel the water to the weepers. Some builders pour the concrete floor slab right on the native soil.
You'll find out when they start breaking it up. Its just these big rains that kill us. Plastic bubble membranes, invented in Europe by Cosella, work two ways. They keep water from reaching the foundation; and if it does, they allow it to flow freely down the wall to the weepers. Finally, you can bring your home or other structure up to current standards and above. This involves excavating around the perimeter of the building down to the footings. Weepers are usually recommended, followed by a couple feet of free draining gravel, sometimes followed by more free draining material, fabric and a clay cap.
These are the most common approaches. But there are others too, including insulation, penetrating sealers on the inside, or the old reliable layers of saturated cloth and fibrated asphalt. All these approaches involve other details as well. The best time to consider waterproofing is before construction starts, as none of the above retrofits address the basement floor or underside of the slab. It ruined the pad of our rug in one part of the basement, but we were on top of it during the hurricane.
However after the rain stoppoed we were in the basement with the shop vac for 12 hrs sucking up the water. I was curious about this as well. I live in NJ and had the same question. Did you find a good company that would install the french drain without tearing up the walls? I've got mold resistant sheetrock up so I would rather keep the walls there.

The Benefits of a Retaining Wall June 22, Spring Basement Leaks March 8, Installing French Drains in a Basement Having water in your basement can lead to a number of problems, which can be costly to fix, as well as pose risks to your health. Where is a French drain located? A French drain is a popular basement waterproofing solution that involves laying either perforated pipe or flexible corrugated pipe in a shallow trench along with gravel. Both are very effective solutions for a wet basement.
Instead, they take water under and around your home and channel it away from the foundation before it has a chance to find its way inside. Depending on how you plan to use your basement, the trench with the perforated pipe might be covered with concrete, a grate, or not at all. Installing a French drain in an existing house is a major construction project.
French drains relieve hydrostatic pressure against your foundation wall or floor by making sure the soil under and around your foundation never gets over-saturated with water. In other words, water getting into your basement is just part of the problem. If this goes on long enough, the walls will start to bow inward and may even crack. Hydrostatic pressure can even force water through a basement wall or floor. Because basements are below grade i. Today, almost all new homes are built with a drain tile system.
A French drain installed either inside, under your basement floor, or outside, buried along the foundation footer, prevents hydrostatic pressure from building up by making sure the soil never gets saturated. All excess water is channeled away from the foundation, either via gravity or by using a sump pump.
Note that a French drain is not the same as a channel drain. Channel drains are above ground drainage systems. An electric sump pump takes the water in the collection pit and pumps it to the surface, away from the foundation. There are two types of sump pumps: submersible and pedestal. Submersible sump pumps go into the collection pit under the basement floor. Once the water in the pit reaches a certain level, the pump kicks in and gets rid of it.
The smaller the collection pit, the more frequently the pump has to work. Pedestal sump pumps sit on a pole above the collection pit and have a float like a toilet tank. When the water in the pit rises, so does the float. When the float rises to a certain point, the pump kicks in and directs the water to the surface.
The cost to install a French drain in the basement of an existing home depends on various factors, including your geographical location, the size of the drain, and whether you DIY not recommended or hire a contractor. The only way to know the cost of installing a basement French drain system is to contact a professional foundation repair contractor for an inspection and estimate.
