A factual side-by-side comparison, and the most closely matched one we publish. EXACT Technology runs five product families, including real match-cure and real active cure control. Sensytec brings two sensor tiers on one platform: SensyRoc II for field crews, SensyCast for plants. Here is where each one fits.
| Capability | Sensytec SensyRoc II | Sensytec SensyCast | EXACT Technology |
|---|---|---|---|
| Built for | Field crews, GCs, jobsite pours | Precast plants, mass pours, multi-pour producers | Producers buying sensing, match-cure, and cure control from one supplier |
| Signals measured | Temperature + electrical resistivity | Temperature + electrical resistivity | Published measurements: temperature, relative humidity, ambient conditions |
| Electrical resistivity in place | Yes, measured in place | Yes, second independent strength signal | Not listed in their published product line |
| Embedded hardware after the pour | Recovered, reusable body, replaceable probes | Recovered, reusable logger | Cast-in-place logger is sacrificial. EXACT: “Sacrificial sensor is installed in formwork (generally on rebar) and covered in concrete” |
| Battery | Non-rechargeable, 1 year | Rechargeable, 3 years | Cast-in-place logger is sacrificial, consumed by the pour |
| Getting data off the sensor | Bluetooth LE to a free iOS/Android app, standard BLE range at the pour | ~1 mile (1.6 km) line of sight, LoRa sub-GHz to a gateway, keeps transmitting after burial | LoRa listed at >800 m line of sight to a Relay, LTE ~1 km line of sight to a tower. xMonitor carries LoRa + LTE Cat M1 with BLE data reclaim; the embedded logger is LoRa-only and needs a Relay |
| Match-cure system | SensyCure, holds companion cylinders within an average of 0.79°F of the bed | Yes (xMatch) | |
| Active cure control (steam / electric) | No. Sensytec monitors and match-cures, it does not drive the cure cycle | Yes (xControl / ControlPro) | |
| Plant certification QC workflows | SensyHub QC: PCI MNL-116/117, NPCA QCM-001, state DOT plant certification, batch and break logs, NCRs, audit exports | xTrack production and QC tracking. EXACT markets: “Generate DOT- and spec-ready reports with a click.” | |
| ASTM C1074 maturity | Yes | Yes | In-place strength reported as estimates derived from maturity modeling |
| AASHTO T-358 / ASTM C1876 | Yes (resistivity) | Yes (resistivity) | Not listed in their published product line |
| Headquarters | Houston, Texas, USA. Made in USA | Toronto, Ontario, Canada | |
EXACT is the broadest stack we compare ourselves against, so the honest list of Sensytec advantages here is short and specific. These are the four.
The maturity method derives strength from one input, temperature history, so everything rests on the calibration holding. SensyCast measures electrical resistivity in the same device, per ASTM C1876 and AASHTO T-358. That is an independent second reading that flags calibration drift, a mix that changed, or an admixture behaving differently than expected, and at later ages it tracks with chloride-ion penetration resistance as a durability indicator. EXACT's published sensor measurements are temperature, relative humidity, and ambient conditions, with in-place strength presented as estimates derived from maturity modeling. We could not find electrical resistivity, or any published durability, corrosion, or chloride-ingress sensing, in their product line.
EXACT's cast-in-place logger is designed to stay in the element. Their own wording: “Sacrificial sensor is installed in formwork (generally on rebar) and covered in concrete”, so the logger itself is consumed by the pour. Both Sensytec sensors are recovered and reused instead: SensyRoc II as a reusable body with replaceable probes on a one-year battery, SensyCast as a reusable IP67 logger on a three-year rechargeable battery. A plant pouring beds every week feels that arithmetic every week.
Both companies do QC software, and EXACT's xTrack covers production and QC tracking. The distinction is what the workflow is built around. The SensyHub QC Module ships checklist modes for PCI MNL-116, MNL-117, NPCA QCM-001, and state DOT plant certification, with batch logs, break logs, NCRs, sticker workflow, and audit-ready exports. EXACT markets reporting output, in their words “Generate DOT- and spec-ready reports with a click.” That is report formatting, which is a different thing from a certification-program workflow, and we did not find PCI MNL-116, MNL-117, or NPCA QCM-001 workflows in their published product line. For general contractors the same module does the jobsite version: strength reports and submittals generated from the pour data rather than assembled in a spreadsheet.
Sensytec is headquartered in Houston, Texas and manufactures in the USA. EXACT is headquartered in Toronto, Ontario, Canada. On federally-funded work with Buy America provisions, US manufacture can simplify procurement. Separately, SensyRoc II and SensyCast both report into SensyHub, so a GC can start with a phone on one jobsite and a producer can add plant beds and a gateway later without changing vendors or losing history.
Match-cure is not the dividing line on this page. EXACT sells xMatch, it is a real match-curing product, and it is prominent in their line. What we publish is our own number and the test behind it: SensyCure holds companion cylinders within an average of 0.79°F of the bed, and our controlled two-day trial shows the cost of getting this wrong: a legacy system over-cured cylinders by up to 27°F. We do not publish a head-to-head accuracy comparison against EXACT, because the two systems are not measured under the same conditions and a number that is not apples-to-apples is worse than no number. Ask both vendors how their figure was measured.
EXACT is the strongest competitor on this list for stack breadth, and there are jobs where they are the better buy:
A concrete technology company headquartered in Toronto, Ontario, Canada, founded in 2017 by Jordan Korenzvit and Stacia Van Zetten. Their published line runs to five product families: xMonitor for sensing, xMatch for match-curing, xControl for cure control, xTrack for production and QC tracking, and the EXACT Portal cloud software. It is the broadest stack of any company we compare ourselves against.
Both, at different ends of the job. SensyRoc II is the field tier: Bluetooth LE, a free iOS and Android app, a reusable body with replaceable probes, one-year battery. SensyCast is the plant tier: temperature plus electrical resistivity, roughly a mile of LoRa sub-GHz range to a gateway, three-year rechargeable battery, IP67, still transmitting after burial. They report into the same platform, so starting on a phone does not mean changing vendors when the work grows.
Yes. xMatch is a real match-curing product, and xControl adds active cure control, which Sensytec does not offer at all. Match-cure is not the dividing line on this comparison. What we publish is our own figure, SensyCure holding companion cylinders within an average of 0.79°F of the bed, verified in our own controlled two-day trial. We do not publish a head-to-head accuracy comparison, because the two systems are not measured under the same conditions.
We could not find electrical resistivity in EXACT's published product line, and no published durability, corrosion, or chloride-ingress sensing either. Their published sensor measurements are temperature, relative humidity, and ambient conditions, with in-place strength presented as estimates derived from maturity modeling. SensyCast measures electrical resistivity in place alongside temperature, per ASTM C1876 and AASHTO T-358.
Their cast-in-place logger is sacrificial. EXACT describes it as “Sacrificial sensor is installed in formwork (generally on rebar) and covered in concrete”, so the logger itself is consumed by the pour. Both Sensytec sensors come back instead: SensyRoc II as a reusable body with replaceable probes, SensyCast as a reusable IP67 logger.
EXACT lists LoRa at more than 800 m line of sight to a Relay and LTE at about 1 km line of sight to a tower. Their xMonitor carries both LoRa (915 MHz in North America, 868 MHz in Europe) and LTE Cat M1, with Bluetooth for offline data reclaim and GPS on newer units, while the embedded logger is LoRa-only and requires a Relay to reach the cloud. SensyCast uses LoRa sub-GHz radio to reach a gateway from roughly a mile, line of sight, and keeps transmitting after burial. SensyRoc II is Bluetooth LE, for crews standing at the pour.
EXACT markets reporting output, in their words “Generate DOT- and spec-ready reports with a click.” That is report formatting rather than a DOT certification, and it is worth reading every vendor's wording in this category carefully, including ours. Where Sensytec goes further is the plant side: the SensyHub QC Module ships workflows for PCI MNL-116, MNL-117, NPCA QCM-001, and state DOT plant certification. Sensytec also manufactures in Houston, Texas, which can simplify Buy America procurement.
It depends on your cure strategy, and we would rather you decide that up front. If you want automated steam or electric cure acceleration, EXACT's xControl does something Sensytec does not. If you want a second independent strength signal, sensors you recover instead of bury, and PCI and NPCA certification workflows built into the QC software, that is Sensytec. Precast and prestressed production is our core market, from bed monitoring through match-cure to transfer strength and detensioning.
Tell us how you pour and cure, and we will tell you which tier fits: SensyRoc II on a phone, or SensyCast with electrical resistivity and a mile of range. If active cure control is your requirement, we will say so.
