Thank you engineer. Well explained and very accurate. I am impressed, most of the videos I watched regarding this trench system --> how to dig, measure, to know what materials to put in and so on, just a lot of misguides and also made misunderstood.

Downspouts should never be tied into a French drain, or perimeter drain system. During substantial rains they can overwhelm the system - and downspouts are an entry point for debris (shingle asphalt, leaves, and such) into the system which can increase the chance of clogging.

Most people cover downspout entry points with a wire grille.
@Bellislawns6 жыл бұрын
theoverengineer doesn’t stop the fact you can overwhelm the system from gutter downspouts. And a wire grill will stop leaves, but not the main reason for concern...shingle asphalt!

How would you install a 2 pipe system on just a repair of one side of the perimeter? I'm currently doing mine. If this was a complete perimeter drain job I would do 2 pipe system all the way around. But in this case it's just a relay of one side of my house. Any advice would be great! Thanks. Technically by code mymunicipality will treat this as a repair so do not have to adapt 2 pipe system. But if I'm doing the whole thing in the future what should I do?
@l.a.l.a4949 Жыл бұрын
If that is the case, that is why we have a "cleanout" and so we can clean once in a while and also the gutter should come with the "filter" protector and prevent all the debris from getting in there.

This is the only proper way to do a french drain around a home. If the company bidding the job is doing a shallow drain and not going down to the footer and waterproofing the outside of the foundation, you're getting ripped off. It'll be more expensive having a company dig down all the way to the footer, but it will completely mitigate the issue of water entering the basement walls and save you costly in the future.

My parents live in my detach garage and have a piece of concrete along outside of garage (like a small side walk) with a negative slope so when it rains water goes towards garage and water has been getting inside. I was thinking about doing a french drain system with corrugated pipe, fabric and gravel. I was wondering if it be enough if I just dig about 6 to 8 " deep to lay corrugated pipe in just to catch water and deter it down to street? I don't think I will need to dig that much since is not a basement is just a garage? Great video by the way.

Well explained. Question 1, where should that drainage evacuate to??? Please?? Question 2, Is it possible to add vertical pipe in a few places, or at corners to do Power Flush now and then?? Thanks!

Answer 1: to a deeper (lower elevation) pipe or sump Answer 2: absolutely do, it might be part of building code requirements already

You gotta wrap the rock and pipe in together in a sort of "burrito wrap" using non-woven double punched geo fabric. You put the fabric in first. Then the pipe. Then the round rock. Then wrap it all together. Otherwise in just 3-4 years the majority of the rock will integrate into the wall of the trench.

Will the dirt just clog the fabric and not allowing the water to get to the pipe?
@ryanglaser53368 ай бұрын
@@michaelpiecuch7313 seepage maybe depends if your dirt is clay or organic material on top of the wrapped drain. River rock is more likely to migrate, hence the name. You want jagged rock, for draifield - it just happens to be cheaper also like video said. In Soth Florida subtropics we use limestone to bed sewer lines and drains, it's also readily they mine it at local quarrys

im putting pond liner against footing wall and on ground 8" out for pipe to sit on hoping this eliminates any water getting on to footing at all what do you guys think???
@theoverengineer4 жыл бұрын
Water can also seep in at the inside of the footing where the floor slab meets the footing or foundation wall. If the subgrade drains groundwater well and there is no cross-slope damming groundwater movement, it should work ...
@dustbat4 ай бұрын
It would seem that would guide water from wall to being trapped behind liner. Could the liner cause it self to float and lift the drain pipe? How did it work out for you?🦇

Just use a 6" drain pipe. In general a 6" pipe will have about 180gpm capacity at 1% slope. 4" (as seen in this video) has about 80gpm at 1% slope.

@@Bellislawns - I agree 6" pipe is awesome at 180 gpm capacity, but two 4" has 160 gpm capacity and if your DIY and can't easily find 6" pipe, then two pipes is the way to go and practically as good, especially considering that DIY will end up costing so much less compared to hiring a good professional company that takes pride in their work.

do you put the drain rock in the trench before the drain pipe or on top of the pipe
@theoverengineer7 жыл бұрын
Building Codes typically require that say 6 or 3 inches (or whatever actual number) of drain rock (of whatever size, always made by crushing, so it has sharp edges and does not clog up easily with silt, not rounded river rock) SURROUND the drain pipe evenly, so that means rocks under, besides and on top. Definitely not burying the pipe under all the drain rock. As ground water rises from the bottom, it fills the space between soil particles, then as it rises fills space between drain rock where it can flow faster, then it reaches the drain pipe where it can flow even faster. Put lots of drain rock under the drain pipe. Covering the top of the drain pipe with drain rock has a much lesser importance.

Right. Pipe should not be level, has to slope 1 or 2% to city sewer line or ditch or something. Really difficult in flat places like Holland.

@@theoverengineer My footer is level. How would I create the slope? My house is 30x30, so, to slope from NE corner to SW corner I would need six inches (30ft + 30ft)... but the footer is only six inches... am I thinking wrong?
@theoverengineer4 жыл бұрын
yeaaahhhh .... not reeeaaalllyyy ..... The highest point will be just below the NE underside of footing, the lowest will be at SW at least 7.25 inches below that: 60 feet = 720 inches, which either times 2% = 14.5 inches of drop or times 1% = 7.25 inches of drop from NE and SW, but the lowest point at SW still has to be higher than sewer inlet elevation, if pumps are not considered.

@@theoverengineer okay. That would put SE corner of drainage below the footer by 1-1/4 inches. I have read that drainage should not be below footer due to possible wash-out under the footer.
