DESIGN, EXCAVATION FOR, AND INSTALLATION OF A COMPLETE DRAINAGE SYSTEM
|
| This project was for the design, excavation, and installation of a drainage system for a new development in South Burlington. The development was a group of condominiums that were installed within the last five years. It consisted of two buildings, three units in one building, and two units in the building directly across and facing the first one. We were contacted by the association president about a problem with water in two of three basements on the three unit building side. We met with the association president on site, and inspected the property, the basements, and the surrounding drainage systems in the area. We came to the conclusion that a footing drain had not been installed when the buildings were built. We discussed a few options with the association at an association meeting. They agreed that they wanted to permanently solve this problem. We designed, excavated, and installed a drainage system for their lot. The system consisted of a footing drain which wrapped around three sides of each building, a storm drain catch basin, a culvert system, and an eave drain downspout system. Here are some pictures from this project. |
We carefully removed all patios, trees, and other landscape features in the area of excavation. We stored these materials out of the way for future replacement.
|
We excavated the foundation wall down to the footing to install the footing drain. The soil was stepped to create a safer trench.
|
The footing drain consists of 1" clean crushed stone, 4" Solid Sewer and Drain Pipe, and Geo Textile Filter Fabric. Here the stone has been installed, the pipe has been fit, covered with stone, and now the stone bed is being covered with Geo Textile Filter Fabric.
|
The foundation wall is being excavated for the installation of more footing drain. At the end of this foundation wall, and footing drain a pre cast concrete storm drain catch basin will be installed to catch the excess water, a culvert system will be installed and outlet the storm drain catch basin into a nearby storm water drainage ditch.
|
We removed the decks from the second building, and placed them off to the side for future replacement.
|
We began excavating and installing the footing drain.
|
Excavating, and installing stone with the exavator as we go. The guys in the trench place the stone as required, fit the pipe, and cover the pipe with stone. They then cover the stone bed, with Geo Textile Filter fabric, and back fill with sand.
|
This is the last wall of building number two. We are now excavating over to where the catch basin will be installed because both sides of the footing drain system outlets into the storm drain catch basin.
|
This is where the catch basin will be installed.

This is the excavation for the installation of the catch basin.

|
We then have to excavate and install a culvert system to outlet the water from the catch basin.

This is another view of excavating for the installation of a culvert system.
|
Here we are back filling the culverts that have already been installed.
|
This picture is being taken from where the culvert has already been installed and back filled over. The lower level is where the next culvert will be installed.
|
This is the last culvert being installed. It outlets into a municipal storm drain.
|
This is final grade after the footing drain, storm drain catch basin, and easement ditch.
|
Here we are installing pipes to outlet the gutter downspouts into the catch basin, to eliminate as much excess ground water as possible. Also known as an eave drain downspout system.
|
This is the trench for the eave drain downspout system along the back wall of the three unit building.
|
 An eave drain downspout system was also installed around the two unit building.
|
Both sides outlet into the storm drain catch basin.
|
Gravel was installed around the storm drain catch basin to prepare the area for future.
|
The patios on the three unit building started to be replaced.
|
 Installation of asphalt. The decks were reinstalled on the two unit building.
|
This is a picture of the back of the three unit building. After the patios were installed and other landscape features replanted, the area was seeded and mulched.
|
This is a picture of the back of the three unit building after the grass has grown, and the mulch has been picked up.

This is the back of the two unit building after the grass has grown, and the mulch as been picked up.
