Most people don’t realize geotextile does this.

Watch the water.

Instead of going straight through the fabric, the non-woven geotextile actually pulls the water sideways through the fibers.

That’s capillary wicking inside the fabric.

Engineering materials often do a lot more than people think.

This video shows it in real time.
Watch the truck tires.

𝗙𝗶𝗿𝘀𝘁 𝘀𝗲𝗰𝘁𝗶𝗼𝗻: Aggregate placed over geogrid.
The truck advances and the aggregate barely moves.

Now the wheels begin exposing the weak subgrade below.
That’s exactly what a proof roll is designed to reveal.
But here’s the important part.

When subgrade fails a proof roll, the old solutions were:

• Over-excavate
• Import new fill
• Disc and dry the soil
• Bring in more equipment

All of which slow the project down.

Today there’s a faster approach.

Run a quick DCP test to measure the subgrade strength.
Use that data to calculate the required aggregate thickness.
Then install geogrid + the designed aggregate section.

The geogrid stabilizes the aggregate layer and distributes loads so the section can bridge weaker soils and move forward with construction.

No major excavation.
No waiting for soil to dry.
No extra equipment cycles.

Sometimes the fastest solution is simply designing the section correctly.

They are lifting a 3' x 7' piece of asphalt, this is not possible with a standard asphalt mix. This asphalt has fibers added to it. It makes asphalt last up to 50% longer. NO more potholes?

Great explanation on why this mesh will make his driveway last longer.

Our driveway installation features Tensar InterAx Geogrids to reinforce, stabilize and filter Pinhoti’s entrance.

What do geogrids actually do on a muddy jobsite?
🧩 Lock aggregate together so your base acts like a stronger, stiffer layer
🚚 Reduce rock and truckloads to reach target thickness
⏱️ Help crews recover faster after rain
🛣️ Resist ruts and deformation for smoother construction

Where they shine: 🚧 roads & streets • 🅿️ parking lots • 🦺 crane/working platforms • 🏭 industrial yards

Pro tips:
📐 Use proper overlaps and keep the grid taut
🔒 Start with a controlled “shaping” lift, then build to thickness
📏 Consistent compaction = consistent performance

Aramid fiber (Kevlar that used in bullet proof vest) is added to the Asphalt mix making it stronger. This project is a series of projects that is incorporating aramid fibers. Our pavements in Iowa take a beating due to the many freeze thaw cycles that incur. These fibers will help the asphalt and extend the life of that pavement.

"Mud got your backhoe down? 😩 That's where geogrid comes in! Think of it like snowshoes for heavy equipment – spreading the load and preventing sinkage. ❄️➡️💪 (See pics for proof!) "

Why is Water Seeping Through the Pavement in the Middle of Winter? 🤔💦

Yesterday was weird, right? One day it’s freezing cold (0-26°F), and the next, it’s nearly 50°F! Last night, even though it was still above freezing, I noticed something strange—water was seeping up through the saw cuts and cracks in our concrete pavement.

At first, I thought, “Where is this water even coming from?!” But after looking into it, it turns out this isn’t just a random fluke—it’s actually a common issue when temps swing wildly in winter. If you’ve seen something like this in your driveway, sidewalk, or parking lot, here’s what’s happening:

1️⃣ Melting Frost & Hydrostatic Pressure
When the top layer of the ground thaws but the deeper soil is still frozen, melted water has nowhere to drain. Instead of soaking down like normal, it gets trapped and builds up pressure, forcing its way up through the easiest escape routes—like the cracks and saw cuts in pavement.

2️⃣ The "Perched Water Table" Effect
Since frozen ground is basically a waterproof layer, water can get stuck just beneath the pavement. As more snow or ice melts, it adds to this trapped water, eventually pushing it upward through small openings in the concrete.

3️⃣ Capillary Action & Poor Drainage
Concrete can absorb and transport water through tiny pores and cracks. If there’s a lot of moisture underneath, it can creep up through the pavement, especially if the drainage isn’t great.

🚨 So what does this mean for the pavement long-term? 🚨

If this happens once or twice, no big deal. But if it keeps repeating throughout the winter, we could see some serious damage, like:
✅ Cracking and spalling – Water seeps in, then expands when it refreezes, breaking apart the concrete over time.
✅ Subgrade erosion – The soil underneath weakens, causing the pavement to sink or become uneven.
✅ Joint deterioration – Small cracks become big cracks, leading to potholes and rough surfaces.
✅ Frost heaving – Water freezes into ice lenses beneath the pavement, pushing it up and creating bumps.
✅ Potholes – The dreaded pothole problem gets worse when water keeps getting into weak spots and breaking them apart under traffic.

💡 How to Prevent This? 💡

Seal cracks & joints – Stop water from getting in before it becomes a problem.
Improve drainage – Make sure water can flow away instead of getting trapped under the pavement.
Use air-entrained concrete – It helps prevent freeze-thaw damage by allowing space for expanding ice.
Regular maintenance – Small repairs now = fewer big issues later!
So if you see water creeping up through pavement during these mid-winter warm-ups, now you know what’s happening! 🌡️💦 Have you noticed this before? Drop a comment if you’ve seen it in your driveway, parking lot, or around town! 👇
