Why opt for French drain systems?
French drain systems are advanced drainage systems that help in averting mold, water damage, and flooding. It is the best system to help you solve the foundation damages. There are two major types of french drain systems — exterior and interior.
Exterior French Drains
These are usually installed on the outer lines of the foundation. It comprises a flexible perforated drain pipe located at the bottom of the foundation footing. Then the gravel is used around the pipe for the filtration of sediments and dirt.
When the water accumulates near the foundation walls, it gets into the pipe and naturally flows towards the house. Therefore, the place needs to have a steep incline so that the drainage water flows away. Having a sufficient outlet is vital to make the best use of exterior french drains.
Exterior French Drain installation is more challenging as it calls for replacing porches, landscaping, decks, and sidewalk. Its maintenance is also a concern due to the excavation in the exteriors. There are chances of clogging of pipes in this system. Since there is a gradual buildup of soil on top of it, clogging is imperative.
Interior French Drains
The next option for the basement waterproofing is the interior French drains system. It also includes a perforated pipe but the installation is near the perimeter around the basement floor. Like the exterior drains, gravel and sediments are necessary to surround the pipe. It then collects water through the basement wall-floor joint and the removal through the foundation pump.
Interior French drain installation is not as labor-intensive as that of exterior ones. Its maintenance is more manageable, and even the pipes are quite accessible. The pipe can get clogged as it buries deep under several feet of dirt. They also stay protected from variations in soil conditions inside the drainage system. But the installation can go on all year round.
Why opt for Surface drains?
When installing the surface drain system, the water collects till the concrete slab and even underneath the beam and pier foundation. If the foundation is sloped towards the house, the surface drain is probably a must.
They are a series of underground pipes that remove the water from basins. Square basins of around 9 to 12 inches are formed for the drainage water to be collected.
Through the pipes, this water is directed to desired outlets. Surface drains are the best when it comes to houses with improperly graded foundations. They also facilitate the capture of rainwater if placed properly.
It is also a viable option for foundation repair. You can further consult with your contractor to make the best choices.
