If you are working in professional gardening, landscaping, agricultural drainage, separation under decorative gravel or stabilization of farm roads, PP non-woven geotextile is the economical option in the family: same needle-punched structure as PET but with polypropylene as the base material—lighter, more manageable, and more resistant to typical fertilizer alkalis and basic soils—. This guide explains how to choose the correct grammage between 100, 200, and 400 g/m² (all in black) according to the application, and how to properly lay, overlap, and cover it.
As with PET non-woven, PP non-woven geotextile is NOT a structural component—its function is to filter, separate, and absorb small puncture efforts, not to provide tensile reinforcement—. If your project requires reinforcement (roads with medium traffic, landscaping with loads, structural weed barrier, low walls), the correct choice is PP woven geotextile or geogrids, not this product. For hydraulic works with structural auditing and a declared lifespan in decades, consider the PET version for its lower creep under continuous load.
Product Specifications
The polypropylene non-woven geotextile is offered in three grammages in black, presented in rolls 5.95 m wide by 100 m long. The following table summarizes the full technical specifications of the three available variants:
| Specification | 100 g/m² | 200 g/m² | 400 g/m² |
|---|---|---|---|
| SKU | 534623 | 623451 | 654237 |

The steps are common to all three variants. The main difference between grammages is puncture resistance and durability under loads: 100 g/m² for aesthetic-functional use without vehicular traffic, 200 g/m² for light traffic (garden carts, rototiller), 400 g/m² for effective geomembrane protection or separation layer under angular aggregate.
The sister guides for PET non-woven geotextile, PET woven geotextile, and PP woven geotextile cover the other three variants of the family and help confirm if the non-woven PP choice is correct for your case.
Step-by-step instructions for use
The following procedure covers the complete installation cycle of PP non-woven geotextile in gardening, drainage, and light construction. The instructions apply to all three grammage variants, with specific notes where the technique differs.
Selecting the correct grammage
Before ordering the material, confirm that the chosen grammage corresponds to the application. 100 g/m² is suitable for residential landscaping, mineral mulching, separation under decorative gravel with foot traffic, and residential filter trenches without equipment passage. 200 g/m² is standard for farm roads, unpaved residential driveways, agricultural drainage with cart traffic, and separation under fine aggregate. 400 g/m² is reserved for geomembrane protection in agricultural reservoirs, separation under coarse angular aggregate, and professional landscaping works with occasional concentrated loads.
Surface preparation
Clear the surface of roots, existing vegetation, and sharp stones that could tear the geotextile. For landscaping with decorative gravel, remove the entire topsoil layer and level it—an uneven bed leaves "pockets" where the geotextile sags and the gravel accumulates irregularly—. For drainage trenches, excavate to the project depth with a drainage slope (1-2%). For reservoir geomembrane protection, remove sharp stones from the supporting soil. The quality of bed preparation is directly proportional to the expected performance of the system.
Unrolling
Unroll manually—the 5.95 m wide roll allows even a single person to handle 100 and 200 g/m² grammages; for 400 g/m², it is advisable to work with two people—. Keep the fabric free of folds and wrinkles. For trenches, lay it in a "U" shape covering the bottom, walls, and leaving 50 cm of excess on each side to wrap the aggregate. For horizontal separation in landscaping, lay it flat on the leveled surface. If working in windy conditions, temporarily secure it with metal garden staples every 1-2 meters to prevent the roll from curling up.
Overlapping at joints
When joining two rolls, overlap by a minimum of 30 cm. In landscaping with decorative gravel where the overlap might be visible if disturbed, use 40-50 cm to ensure the system maintains continuity even if the wind moves the geotextile before covering. For French drains, the ends of the roll should be laid over the bottom of the trench, not cut flush. For reservoir geomembrane protection, increase the overlap to 50 cm without exception.
In landscaping with decorative gravel, 100 g/m² PP non-woven geotextile can be visible at the edges and, although functional, looks aesthetically poor compared to a professional finish. The landscaper's technique is to bury the geotextile edges 5-10 cm below the final gravel level: dig a small perimeter trench, fold the geotextile down, and cover with gravel. This gives the finished garden the appearance of "gravel without geotextile" while retaining all the separation function. For premium residences, the landscaper's extra time is worth it.
Covering with the top layer
Cover the geotextile with the intended material without unnecessary delay. Exposure to Caribbean sun degrades PP faster than PET; ideally, cover it on the same day of installation and at most within the next 3-5 days. For landscaping with decorative gravel, dump the gravel evenly and gently rake to level it without puncturing the geotextile with the rake. For French drains, fill with clean drainage aggregate and fold the excess to close the wrapper. For geomembrane protection, install the membrane over the geotextile with due care for the specific system.
Do not install PP non-woven geotextile in areas with heavy vehicle traffic or concentrated loads (trucks, construction machinery, large static loads). Non-woven PP has low puncture resistance under concentrated loads — even 400 g/m² can tear under the point weight of a tractor wheel on loose aggregate. For vehicle traffic areas, use PP biaxial geogrid or PP woven geotextile, not this product.
Non-woven PP or non-woven PET for your application?
The two products share a function but have different properties. PET performs better in terms of long-term creep (audited hydraulic works, dams, road separation under serious paved roads). PP is more economical and more resistant to typical fertilizer alkalis and basic soils. Ask the assistant with your scenario, and we will guide you to the choice that combines function and cost consistent with your project.
Complementary Products
To complement PP non-woven geotextile in gardening, agricultural drainage, and light construction, the following products cover the most common adjacent needs:
The non-woven PET geotextile is the premium version of the same functional principle, indicated when low long-term creep is a factor (audited hydraulic works, dams, road separation under serious paved roads). The PP woven geotextile is the choice when the project needs tensile reinforcement in addition to separation: farm roads with heavier traffic, structural weed control, low walls. Metal garden staples are the natural tool for securing geotextile in gardening during spreading and before covering with gravel. The PP biaxial geogrid is combined with non-woven geotextile in a double-layer system for soft subgrades with vehicular traffic.
Maintenance and Care
PP non-woven geotextile buried under a layer of gravel or soil requires no maintenance during its useful life. Where periodic inspection is advisable is in gardening with decorative gravel: over time, gravel can shift due to wind, heavy rain, or foot traffic, exposing the edges of the geotextile. If this occurs, redistribute the gravel or, if the exposed area is large, lift the gravel in that area, adjust the geotextile, and re-cover.
For storage prior to installation, keep rolls horizontal on flat pallets, covered against direct sunlight. PP is more sensitive to UV than PET; a roll exposed to the Caribbean sun for several months loses strength and becomes brittle. Inspect each roll before bringing it to the job site to identify creases, cuts, or edge damage. For small quantities (partial rolls) kept in stock between jobs, retain the original packaging for UV protection.
Frequently Asked Questions (FAQ)
Which grammage should I choose among 100, 200, and 400 g/m²?
The criterion is the severity of the environment in your specific application. 100 g/m² covers residential gardening without vehicular traffic, mineral mulching, and separation under decorative gravel. 200 g/m² is the standard for farm roads with light traffic, unpaved residential driveways, and agricultural drainage with occasional vehicle passage. 400 g/m² is reserved for geomembrane protection in agricultural reservoirs, light civil works, and separation under coarse angular aggregate. If you are between two options due to reasonable doubts, increase the grammage: the extra cost is usually less than that of reinstalling the system when the lower option failed.
PP or PET for my application?
PP is more economical, lighter (more manually manageable), more resistant to typical fertilizer alkalis and basic soils, and ideal for agro-industry and gardening. PET has better long-term creep behavior, a critical condition in audited hydraulic works, dams, and road separation under paved roads with structural auditing. For residential gardening, landscaping, agricultural drainage, and light construction, PP is the correct choice. For hydraulic works with a declared lifespan in decades, PET justifies the extra cost.
How many rolls do I need for my project?
A 5.95 × 100 m roll is equivalent to 595 nominal m². To calculate the actual number, subtract for overlap: with a standard 30 cm overlap, efficiency is 90-92%. For a surface area of 500 m², calculate one roll (with 50-60 m² leftover for adjustments). For French drainage with complete aggregate wrapping, consumption is approximately double the basic trench perimeter per linear meter. In gardening with irregular shapes, reserve an additional 10-15% for cuts and adjustments — leftover geotextile in gardening almost always finds secondary uses (additional beds, large planters, patches), so having too much is less costly than running out and having to order an extra roll for 50 m².
