Great video. You mention concrete overlay a few times (ie 4:49 - 5:54). I don't see the concrete over anything. Isn't the concrete 'under' the pavers and under the geotextile? Or are you indicating the overlay means over the base?

Yeah, concrete overlay refers to concrete being the base and the pavers are overlayed on top.

I am building a raised paver patio with a 3' high retaining wall and 40x10 permeable paver patio on top. I initially planned to use woven (SRW SS5) all throughout because i have a mix of sandy and clay soils and thought that would be best for stability. After excavation I saw that the base of the retaining wall had most of the clay and the soil higher was much more sandy. After that experience and watching your video I decided to use the woven under the wall to help stabilize the soil that has more clay content. I am already planning to use biaxial geogrid to stabilize patio area so I will use non woven behind the wall drainage aggregate and in the patio area since drainage is more important there. The geogrid will help to tie the patio and wall together.

Great content, if using loose base such as 57 gravel with no fines under a paver patio and you used woven fabric what would happen to all of the water? Would the polymeric sand keep the water from pooling underneath the patio?

[@iamahardscaper]

Yes, to an extent. Woven will still allow water through but it impedes the passage of water. If you have a sandy subsoil, it will flow through it and into your subsoil. If you have a clay soil, it’s recommended that you collect the water and move it out of the system

We have hard compacted but thin topsoil layer on top of rock here in Texas. I'm planning to cover side yard with washed granite gravel with a walkway of scpaed out 2'x4' limestone paver slabs. WIll compact 3/4" yellow limestone road base prior to adding the finish gravel layer. Should I be laying non-woven landscape fabric under the road base or between the road base and the washed granite gravel? The ground is quite hard and difficult to dig or level, therefore I was going to rely on a thick, compacted and leveled layer of road base to create a stable and flat subbase since I can't really excavate and level the raw ground effectively. Therefore, I wasn't sure if the landscape fabric should lie directly on the raw ground or on the leveled road base. Thanks!!

If you are removing the topsoil and installing the road base on top of rock, I would just have geotextile separating the granite. If you still have topsoil, I would also add it to the base. hope that helps

Under a storage shed you want to stop moisture from coming up through the concrete slab and aren’t concerned with drainage; I.e. it’s a vapor barrier like a house with a slab on grade condition. The classic is visqueen plastic but there are more durable and newer vapor bassists that stand up to the rough conditions of a construction site. Also, pour the concrete over the vapor barrier over the base gravel. PERMINATOR® underslab vapor barrier is a new generation of polyolefin-based resin/chemical technology. PERMINATOR provides the vapor barrier industry with a highly effective, economical choice for helping to reduce the penetration of moisture and water vapor through the slab into the structure, thereby helping to reduce fungus, mildew, and mold growth. PERMINATOR also helps reduce radon gas from entering the structure. New resin technology allows dramatically greater puncture resistance while maintaining one of the lowest perm ratings in the market.

[@elbuggo]

@@zanepaxton7452 You may be answering a question that hasn't been asked. If you throw 10" of gravel over 10" of mud, you get 20" of mud. I think this is what he will prevent, and not the moisture to stop moisture from coming up through the concrete slab. Radon is an ridiculously hyped problem. I don't think they can name 1 person who has felt a problem with that. The problem is allegedly demonstrated in dubious computer models only.

[@zanepaxton7452]

@@elbuggo you bring up an interesting point when the soil is muddy or if the water table is at the surface. The main purpose of gravel under a building slab is as a capillary break to help keep the bulk of water away from the slab. I live near the Oregon coast in California and it rains 75” a year so the soil is very saturated 7 months of the year so I’m facing the same issue. I’m about to expand a workshop. Under a building slab the base rock also increases the structural capacity of the soil which is desirable. So… from top to bottom this seems reasonable: A reinforced concrete slab over A quality vapor barrier over Base rock/angular gravel over Geotextile fabric over Compacted native soil In that design we don’t want moisture to come up into the structure so the vapor barrier is valid. Then we don’t want to trap moisture in the base rock/angular gravel. So providing a geotextile under the angular crushed rock that drains well is important so the moisture can drain out and not be trapped as well as not mix with any mud below. Probably a woven fabric for structural strength similar to a driveway. Having said all that, best practice is to have positive drainage away from a structure all around at least 5’. In my more extreme climate I’m planning on installing a French drain around my garage to drain away the ground water to keep the slab dry. When it rains here the water table is at the ground level and higher (ponding). I’m also planning on a higher perimeter concrete curb because there’s a lot of rain splash that typically rots away the plywood siding that is popular because it’s cheap.

[@danielfinerty8086]

For a patio adjoining the side of a garage and a concrete driveway slab, it sound like nonwoven geo fabric would be best plus or without geo grid for additional support. But any thoughts on whether to place some woven geo fabric near the base of the garage and the slab to prevent erosion from seepage through the nonwoven and ensure water is pushed away from those two structures? Also thinking about woven at the outside edges to ensure that any water that runs off will not undercut the patio. Any thoughts appreciated.

[@iamahardscaper]

Sorry I can’t quite picture this. Both fabrics will separate material that you don’t want mixing. Woven will not be great for drainage so if you need drainage go with nonwoven. If you need added stability add in the box axial

Thank you so much

[@iamahardscaper]

Pea Gravel patios are not too popular in this area. I wouldn't think it would need more than just fabric and the depth you want to go with the pea gravel. Base is to ensure there is drainage and to prevent heaving. If your patio is gravel, you are not worried about that especially since it is just pea gravel that is easily moved whenever you step into it. I would think it would definitely be trouble to maintain if you have a lot of vegetation around as it will be home to weeds and insects over time.

It is tough to say without seeing the site. If you are not having water troubles in your basement from this issue, I may opt for the nonwoven. But if the erosion is really bad, you may want to go for the woven to redirect the water. You could fill in the eroded areas with a 3/4” angular crushed stone or larger crushed stone without fines as these will lock up better to prevent further erosion especially if it won’t be seen, then fabric, then your river rock.

The correct 'geotextile' is for purposedly used for road construction made from pp/pet high strength multifilament yarn with or without mono yarn.

You are right, there are actually 3 different woven geotextiles. Multi, mono, and slit, at least that relate to the Hardscape industry.

Removing the material with the grass attached is almost as difficult, but that's what I did. The newer woven material does not seem to have this felt sub-surface, but I'm reluctant to use it. The non-woven material I just looked at is not felt-like at all - it's pressed together & thin but seems strong. My neighbor says B-grass grew roots under her non-woven material, but has not penetrated it ... yet.

We use a 3/4” crushed stone for our base with a 1” bedding layer of 1/4” crushed stone. Base depth depends on the project. Minimum of 6-8” for patios and retaining walls. Minimum 12” for driveways.

[@domilion2008]

@@iamahardscaper can the 1/4 crushed stone aka 1/4 minus (down), be used instead of sand?

[@iamahardscaper]

No, there is no use for 1/4" minus or stone dust or limestone screenings.

Great video! Question: I have about a 30'x6' walkway on the side of my house where we've had some leaking into the foundation. I'm planning to put a french drain in at the fence line away from the house sloping to the backyard. Question is to slope the 5-6 feet away from the foundation and into the french drain, should I use woven geotextile to help push that water away from the house into the drain? It's just river rock and soil right now so the water tends to just sink in and find it's way to the foundation so I'm thinking using the less permeable fabric tied up tight to my foundation and slope down would be the best move but let me know if that doesn't make sense. Thanks very much!!

[@iamahardscaper]

Yeah that would be a good use of the woven geotextile. Just do not use it around the French Drain.

[@pkehoe88]

@@iamahardscaper Thanks so much!

[@paulfromcda8440]

Use MiraDRAIN against the foundation. Check out youtube videos on it...there are plenty.

[@LuminairPrime]

TLDR: non-woven is for drains. It separates the soil types and extends the life of the gravel. Thicker fabric is for when the thinner stuff would rip during install. Lap the fabric over itself so it stays together. And for what it's worth, when I dug up an old drain, the fabric (and spikes) had shifted all over the place, so when I installed it back, I used a bead of polyurethane sealant (Quad Max) to fasten the fabric laps together.

Which one is best for raised bed vegetable planters?

[@iamahardscaper]

Likely going to want non woven

[@mitchellkasdin1899]

So to clarify with having spoken to a manufacturer, the non-woven is geo textile has good flow through rates. I recall a 92% permeability property, but since the fabric is on the ground the rate of absorption into the soil is a determining factor. The ground will absorb at a given rate, although you have a permeable substrate. Therefore, pouring a drink through the material onto the ground is not how the material necessarily works. There are also different weights or thickness for the non woven geo textile, depending on the application. Soil types, slope or pitch would increase or decrease the flow-through of liquids, water, fruit juice, etc. I’ve also used fabric staples and punctured the woven geo textile throughout when doing xeriscape over large areas. The woven geo textile is much less money then non woven.

[@iamahardscaper]

All of this is true. This was just a demonstration to show the difference between the two. It would take a lot more to show the difference between the two considering multiple factors like varying soil types that will be beneath either of them and what the flow through rate would be then. Maybe one day… but for now we have this video and our in-depth article.

[@mitchellkasdin1899]

@@iamahardscaper true. Also with the woven you can put a cut mark or a hole and then cover it with some non woven geo textile. Also another trick if the area is sloped you can have the seam facing the pitch to collect water under the material in the gap. I use the woven for a weed barrier when laying down decorative rock so the hydraulics of the wet soil doesn’t burry the gravel or rock.

Where is the best place to order the biaxial geogrid and non-woven geotextile? Looks like Homedepot and Lowes do not carry it.

[@StephanieHernandez-bg4tn]

I’m not sure what to do after watching the video. I had non woven geotextile in my backyard. The dirt was compacted and we put rocks on top of the non woven geotextile. Now that it’s been raining, we’ve noticed there’s been weeds growing through it. Any recommendation why that is? Should we have used the woven option?

[@iamahardscaper]

no, it wont stop weed growth from the top down, only the bottom up for the most part and depending on the weight of the fabric. You'll always get weed growth anywhere those seeds can get to.

[@Overthetop242]

I want to lay down fabric under a gravel driveway area to prevent weed growth from the subsoil. It seems that woven is best...water is not an issue in either direction (groundwater coming up, or surface water drainage). Will the woven prevent weed penetration?

[@iamahardscaper]

It is important to note that it is not necessarily for weed growth. Weed growth comes from top down and not from the bottom up. Woven for added reinforcement and separation. Non woven for drainage and separation.

[@Overthetop242]

@@iamahardscaper Yes it is true that NEW weed seeds will come from above and need attention, but the roots will be shallow and in the undesirable growing medium of crushed stone. But in the original soil that will be under the new crushed stone driveway there will be many many noxious weed seeds from the eras. Most of those will still want to sprout, and some will make it through the crushed stone (they will have deep roots and hard to eradicate) and some will not make it. The question is... will the ones that will make it through the crushed stone be more deterred by the woven or the unwoven fabric. Thanks a lot for your lightning quick reply. I appreciate it. Great channel.

[@iamahardscaper]

Interesting. Either will be fine, but woven has higher tensile strength.

[@ATappin]

I am doing a gravel courtyard area. I have the dirt all compacted, but it is a super wet area in the winter time with the rain (pacific northwest) which I've mitigated by adding french drains and a sump pit in the middle. We are wanting to do a pea gravel top layer. Should I put the geotextile followed by a base layer of gravel and then the top few inches be pea gravel? Or should I reinforce the dirt layer more by compacting some crushed asphalt or concrete first then do the fabric? Or is the Geogrid recommended?

[@iamahardscaper]

I don’t think that requires that much prep to be honest. That’s not a popular thing here, but I’d assume digging down a bit maybe compacting, adding geotextile and then your pea gravel right on top. It’s not like you’re going to see any movement on the surface since it is just gravel.

[@Alvink2015]

Please help, I have a 24” area around my concrete patio that was sinking because it had 8 inches of play sand underneath it with no retaining wall around it , I removed the entire area and all of the sand and built concrete forms 4 inches deep and 3 1/half inches wide all the way around, I used 3/4” angular cut lime stone over the subgrade, which was a clay dirt mixture and compacted it with a plate compactor over 100 times and now that I’m at the point of screeding the 1” of 1/4”clean angular cut limestone before setting the pavers back I realized I forgot to lay down the woven geotextile fabric underneath the 3/4” limestone base 🤦🏻 What do you recommend I do at this point ? What’s so frustrating is that I originally had the fabric layed down over the subgrade but I took it out to to compact some stone into the dirt and clay mixture so that it would be more water permeable and not like a solid sheet that water won’t let water in but I forgot to put the fabric back down when I put the rest of the stone in. Any advice will help at this point, thank you.

I have never met a concrete contractor that uses geotextile to be honest. But the only way to get it in there would be to start again

@@iamahardscaper The area I’m talking about where the geotextile fabric wasn’t laid has pavers going on it not concrete, I built concrete forms around the outer perimeter of where that pavers will be placed so they don’t fall back. Basically, my question is there anything to do it extend the life of the pavers and keep them from sinking now that that geotextile fabric is not underneath the base

[@felixyusupov7299]

I assume you would use non-woven instead of a woven geotextile fabric for a dry creek drainage application. Please confirm.

[@iamahardscaper]

If you want the water to drain through and you are only looking for separation.

[@scottkain7474]

So if I am putting essentially a french drain behind my 6x6 timber retaining wall, then I want to use the non-woven to maximize drainage to keep static pressure minimal and keep the wall from pushing out/over? Because I dont need reinforcement in that case?

[@iamahardscaper]

I don’t know engineering for timber retaining walls. But I would assume you would want that drain at the base of the wall much like in a segmental retaining wall installation because a French drain is more so meant for surface water.

So if I'm trying to get water away from a house that has pitch going towards it instead of away, i would install woven on the bottom and non woven on the top under the landscape stone, with drainage pipe between. Correct?

If your yard is sloped towards the house I would recommend a retaining wall to help flatten the yard. Then you could address any other water problems with a French drain as you described there and you wouldn’t need woven.
