10 ft of double-walled steel pipe followed by high-strength concrete. Our deepest pier, built for the worst DFW soil conditions. ~100% deeper than the ST1. Free lifetime transferable warranty.
The ST10 is Stratum’s deepest pier system, built for the most difficult soil conditions in Dallas-Fort Worth. It starts with 10 ft of double-walled steel pipe (2 7/8″ outer, 2 3/8″ inner diameter), then transitions to 11,980 PSI concrete cylinders pressed to refusal. That much steel blows past every shallow obstacle and reaches soil that lighter systems can’t touch. The ST10 averages ~100% deeper than the ST1, giving it the most friction and the strongest hold of any system we offer. It comes with a free lifetime transferable warranty.
Some DFW homes sit on soil so deep and unstable that 1 or 3 ft of steel won’t cut it. The ground shifts too far down, the clay is too thick, or the house is too heavy. That’s what the ST10 is for.
It leads with 10 ft of double-walled steel pipe, which drives past everything, hard layers, fill material, deep clay, before the concrete even begins. Once the steel is in, 11,980 PSI concrete cylinders take over and get pressed to refusal against the full weight of the structure.
The result is a pier that goes ~100% deeper than the ST1 on average. All that extra depth means significantly more soil contact, more friction, and the strongest hold we can put under a home. It’s the system we use when the job demands it.
Same day installation for most homes. Here’s the full process at each pier location.
We dig down at each pier location along the foundation footing and set a steel bracket beneath the beam. The bracket is the platform everything gets pressed from.
10 ft of double-walled steel pipe (2 7/8″ outer, 2 3/8″ inner diameter) is hydraulically pressed into the ground. This is the most steel of any system we offer. It pushes through hard layers, deep clay, old fill, and anything else between the surface and stable soil.
Once the steel is in, 11,980 PSI concrete cylinders (6″ diameter, 1 ft each) take over. They’re pressed one at a time against the full weight of the structure until the ground won’t compress any further.
A 9,860 PSI cap block goes on top. Then Schedule #3 rebar drops down the center of the entire column, tying all the steel and concrete together into one solid pier from top to bottom.
Hydraulic jacks press through the bracket to raise the foundation back toward its original elevation. Once we hit the target, the bracket is locked off for permanent support.
Every hole is backfilled and compacted. We clean up the same day. Your free lifetime transferable warranty starts immediately.
The ST1 has 1 ft of steel. The ST3 has 3 ft. The ST10 has 10. Here’s why that kind of depth matters.
10 ft of double-walled steel doesn’t slow down for hard layers, old construction fill, or rocky patches. Where the ST1 and ST3 might meet resistance, the ST10 keeps going. It reaches soil that lighter piers simply can’t get to.
Double the depth of the ST1 means the pier is bearing on soil far below the moisture swings that cause foundation problems. Down there, the clay is more stable and less affected by drought and rain cycles.
More depth means more surface area pressed against the soil. The ST10 has the most soil contact of any system we offer, which gives it the most friction and the strongest resistance to movement over time.
The steel pipe is double-walled (2 7/8″ outer, 2 3/8″ inner diameter), not single-wall. That makes it significantly stiffer and harder to bend or buckle during driving, even at 10 ft of depth.
Most homes don’t need this much pier. But when they do, nothing else will work.
If your home has major settling, large cracks through brick or drywall, visibly uneven floors, or doors and windows that are way out of square, you likely need the depth only the ST10 can reach.
Two-story homes, homes with stone or brick veneer, and larger structures put a lot of weight on the foundation. The ST10’s deep bearing point handles that load without compromise.
Some areas of DFW have unusually deep expansive clay, thick fill layers, or soil that’s unstable further down than normal. The ST10 powers through all of it to reach solid ground.
If your home has had foundation work before and the problems came back, the original piers may not have gone deep enough. The ST10 goes deeper than anything most companies offer.
Most homes are fine with the ST1 or ST3. We’ll tell you which one during your free inspection. We never recommend the ST10 unless the soil and the house actually call for it.
Not every home needs the ST10. Here are the other two options.
Starts with 1 ft of steel, then all concrete. Built to replace the industry standard pier with nearly 2x stronger concrete. The right call when soil conditions are standard and budget matters.
Starts with 3 ft of steel, then switches to concrete. Punches through shallow hard spots and goes ~50% deeper than the ST1. The sweet spot for most DFW homes that need more than concrete alone.
