Drain Tile Systems
One of the greatest challenges most homeowners’ face regards yard drainage. This is more so in low-lying areas where storms are common. Despite yard drainage being an exterior issue, the internal impact it has on your property is even more urgent.
During a storm, lateral or hydrostatic pressure caused by underground and surface water will push through foundation walls. Water will eventually compromise your foundation which leads to basement and crawl space moisture issues.
When the integrity of a foundation is compromised the walls can either bulge or bow which greatly jeopardizes your home’s strength. Other problems associated with such drainage problems include basement flooding, toxic black mold growth, poor indoor air quality (IAQ), among others.
Drain Tile Systems as the Ideal Drainage Solution
There are many waterproofing solutions available but the drain tile systems win the award for versatility among them all. This system also known as a weeping tile can either be installed on the interior perimeter of your home’s foundation or along the external walls as the foundation is being built.
The ingenuity of this drainage solution lays in its capability to draw both surface and ground water through its perforated side. It is in the simplest definition a PVC pipe with weeping holes on one side which drains collected water into a sump pump or away from your home’s foundation through a storm pipe.
The main types of drain tiles include:
Internal Drain Tile
These drain tile systems are ideal in a home which is already complete. It is best where you want to take advantage of the versatile nature of this waterproofing solution. The process entails:
- Laying the system within the slab edge or above the concrete slab in an existing home.
- A portion of the basement floor is removed and a trench is dug to allow placement of the PVC pipe.
- Placing of the perforated pipe and covering up with washed gravel to allow water to seep through.
- Finishing of the concrete floor to its original state.
Exterior Drain Tile
These are placed during construction and entail:
- Mapping the location of the drain.
- Excavation of the area around the foundation wall down to the footers.
- Laying of the PVC perforated pipe a day after the footer has been poured considering the gradient away from the walls.
- Covering with washed gravel or other materials that will allow flow of water from the soil into the drain.
- Covering of the trench with backfill.
While the drain tile systems might sound easy to install, it is important to remember that specialized tools and skills are required. A professional contractor will also assess the gradient in order to install a fully efficient system to protect your foundation.
