Built to replace the industry standard pier. Nearly 2x stronger concrete that goes 3 ft deeper on average, with a free lifetime transferable warranty.
The ST1 is Stratum Foundation Repair’s concrete pressed pier system, built to replace the industry standard pier. It starts with 1 ft of steel pipe at the top, then transitions to 11,980 PSI concrete cylinders, which is nearly twice the strength most companies use. That stronger concrete is why the ST1 goes an average of 3 ft deeper than conventional piers. Each one is pressed against the full weight of the structure until the ground won’t take any more, then reinforced with Schedule #3 rebar down the center. It’s the most affordable of Stratum’s three pier systems and comes with a free lifetime transferable warranty.
Most foundation repair companies use generic concrete cylinders rated around 5,000–6,000 PSI. We built the ST1 to beat that standard.
Our concrete is rated at 11,980 PSI, nearly twice the strength of what most companies use. That extra strength lets the ST1 push deeper into North Texas clay before the ground pushes back, averaging 3 ft deeper than a standard pier.
The pier starts with 1 ft of steel pipe at the top, which connects to the foundation bracket. From there it transitions to concrete cylinders, pressed one at a time against the full weight of your home until the soil won’t compress any further. Then Schedule #3 rebar goes down the center of the whole column to tie it all together.
Every ST1 goes in the same way. Here’s what happens at each pier location.
We dig down at each pier location along your foundation’s footing and position a steel bracket beneath the beam. This bracket is the platform the pier gets pressed from.
A 1 ft steel pipe goes in first. It connects the bracket to the concrete column and gives the pier a solid starting point.
11,980 PSI concrete cylinders (6″ diameter, 1 ft long each) are hydraulically pressed one at a time against the full weight of the structure. We keep going until the pier hits refusal, the point where the ground won’t compress any further and the pier is locked into load-bearing soil.
A 9,860 PSI finishing cap block goes on top. Then Schedule #3 rebar is dropped down the center of the entire stack, which ties all the cylinders together into one solid column.
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.
Each excavation is backfilled and compacted. The work area is cleaned up the same day. Your free lifetime transferable warranty goes into effect immediately.
Most companies in DFW still use generic pressed piers. Here’s how the ST1 compares.
| Feature | Industry Standard | Stratum ST1 |
|---|---|---|
| Concrete Strength | ~5,000–6,000 PSI | 11,980 PSI |
| Average Depth | Industry baseline | 3 ft deeper on average |
| Steel Starter Section | ✗ None | ✓ 1 ft steel pipe |
| Center Rebar | ✗ Varies by company | ✓ Schedule #3 rebar |
| Finishing Cap | Standard concrete | 9,860 PSI cap block |
| Cylinder Specs | Generic 6″ cylinders | 6″ × 12″ engineered cylinders |
| Warranty | Varies (often limited) | ✓ Free lifetime transferable |
Need to go deeper? Check out the ST3 and ST10 for homes where concrete alone can’t reach stable ground.
It’s our most affordable pier and handles the majority of DFW foundation repairs.
If you’re seeing cracked drywall, sticking doors, or minor settling and the soil conditions are typical for the area, the ST1 will get the job done.
You get the same lifetime warranty as our other systems at a lower price point. If you don’t need the extra steel depth of the ST3 or ST10, the ST1 saves you money without cutting corners.
In most North Texas neighborhoods, the clay soil lets concrete piers reach stable ground. And because the ST1’s concrete is nearly 2x stronger, it pushes 3 ft deeper than standard piers before the ground stops it.
For a single-story slab-on-grade home with normal soil conditions, the ST1 has more than enough depth and strength to hold.
Every free inspection includes a full assessment and system recommendation. We’ll tell you which pier your home actually needs and why. No pressure.
If the ST1 can’t reach stable ground, we have two systems with more steel that go deeper.
Starts with 3 ft of steel, then switches to concrete cylinders pressed to refusal. The extra steel punches through shallow hard spots that would stop a concrete-only pier.
Starts with 10 ft of double-walled steel pipe, then finishes with concrete cylinders. This is the system for bad soil, heavy homes, and multi-story structures.
Get a free inspection with no obligation. We’ll check your foundation, tell you which system it needs, and explain everything before you decide.
