Basement Waterproofing Using French Drain
French drains prevent water from flooding on your basement floors. When it is rainy and wet outside, the soil around your foundation is saturated with water. Since water weighs more, it pushes against the walls of your basement and if the water is too much, it can even move up your basement slab. This is where affordable roof restorations are vital in helping you keep your basement safe from all the rainwater.
A damp-proofing membrane that usually consists of asphalt coating is used to hold this water back. However, a small gap or crack on the membrane can allow a lot of water in making the basement flood.
However, instead of risking major leakage and fighting hydrostatic pressure, when your house is being built, you can have footing of the French drain installed externally. It releases the pressure as well as drain the water away from your house. In case an exterior French drain fails, it causes the affected basements to flood.
When your exterior drain fails, either you can install a new drain by digging up or you can install an interior French drain. Installing a new drain requires digging around your home perimeter affecting the utilities, landscaping, and walkways. This disruption of your normal routine is very significant.
To avoid all this, consider installing an interior French drain. It requires less time to install and causes less disruption. Interior French drain also cost less and you do not have to worry about future clogging
Where to install a French drain.
You can have French drains installed in any location around the foundation. An exterior French drain is installed on the outside edge of a footing while interior French drains are installed on the inside edge of the footing. Both internal and external are prone to clogging, however, for long-lasting and effective water control, keep French drain out of the mud zone and along the footing edge.
How to install a French drain
First, we will have your stuff moved and covered with plastic, then lay tarps on the floor. A deep channel is then dug and pitched. For walls constructed using cinder block, we tap through the lowest course of the block and then we install weep holes for draining the water in the walls. An HDPE pipe is installed in the trench for taking water to a sump sea.
We then install a 300 gallon/ hour submersible pump covered with a polyethylene liner to discharge water. Normally, for a basement whose perimeter is 124 feet and below, only one sump pump is used. For basements whose perimeter range from 125-249, a two-sump pump is installed.
Next, we install a poly drain wallboard on the perimeter bottom as well as over the whole basement trench. The drainage pipe and the wallboard are then covered with gravel and the basement floor is cemented back to its level.
Lastly, we clean up, remove all the plastic covers, and leave your basement in a better state with no problems of flooding in the future.
We install only quality and patented drainage system at the clear water zone. Our innovative designs combined with the location will give you the best protection against the intrusion of water.
