Regina's Heated Floor Underlayment, Poured Around the Tubing
Radiant heat lives or dies by the concrete encasing it. Regina Concrete pours heated underlayment around hydronic PEX or electric mat systems so warmth reaches the finished surface evenly. Free written estimate on every job.
Where Heated Floor Underlayment Makes or Breaks the System
Radiant heat is a simple idea: warm the floor, let the floor warm the room. The concrete underlayment is the part that determines whether that idea holds up in practice. Voids around the tubing create dead zones where heat stalls. Low-density spots produce uneven surface temperatures. A slab that isn't flat enough for the finish above adds another layer of problems before the room is even usable.
Regina Concrete pours the underlayment so the mix flows completely around every loop of tubing, hydronic PEX or electric mat, with no air pockets and no soft spots. The result is a dense, flat slab that conducts heat uniformly to whatever finish sits on top. We use products rated for thermal cycling so the concrete doesn't develop stress cracks as the system heats and cools through a Saskatchewan winter. Check our Ardex self-leveling systems and Mapei self-leveling products for the mix options we draw from.
The finish layer goes on after the underlayment cures: polished concrete floors for a hard, low-maintenance surface, or stained concrete floors for colour. Tile and plank bond directly to the underlayment as well. The heat path is underlayment to finish to room, and it works because each layer is built to spec.

How Heated Floor Underlayment Gets Poured in Regina
On-site layout review
Before anything goes down, we walk the room with you and your heating contractor. Loop spacing, manifold position, insulation board placement and the target finished elevation all get confirmed so the pour is planned around the actual system, not a guess.
Tubing secured and pressure-tested
The heating contractor fastens PEX or electric mat to the substrate. Every loop is brought to operating pressure and held there. Any leak shows up now, before concrete covers it permanently. We don't pour until the pressure test passes.
Underlayment poured and screeded
The self-leveling mix goes in around the tubing, flowing into every gap and settling to the finished elevation. The result is a dense, void-free encasement with a flat top surface ready for whatever finish the room calls for.
Cure, retest, hand off
The underlayment cures to full strength on schedule. The tubing is pressure-tested a second time to confirm the pour didn't stress any joints. Once both checks pass, the surface is handed off for the finish installation above.

Choosing a Polished, Epoxy, or Micro-Topping Finish Over Radiant Heat
Once the heated underlayment reaches full cure, the surface is ready for the finish layer. The choice comes down to how the room is used and what look the homeowner wants. Polished concrete is the most common pairing in Regina basements and main-floor additions: the dense, ground surface conducts heat efficiently and needs nothing more than occasional damp-mopping to stay clean. See the polished concrete floors page for grit levels and sheen options.
Rooms where a thinner build-up matters, bathrooms, mudrooms, additions with tight door-clearance tolerances, often go with micro-topping over concrete. The overlay adds only a few millimetres and still takes the heat from below without issue. For homeowners who want colour worked into the surface, stained concrete floors apply directly to the cured underlayment. Tile and plank set on top with standard adhesive. If the existing substrate under the radiant system needs levelling first, self-leveling concrete underlayment handles that prep step before the tubing goes in.
Heated Floor Underlayment, Questions Regina Homeowners Ask
System types, finish compatibility, response time, cracking risk, and how the heating contractor fits in.
Yes, both. Hydronic systems run heated water through PEX tubing fastened to the substrate; electric systems use mats or cables. Either gets encased in the underlayment the same way, with the heating contractor handling the source side.
Faster with thinner underlayment, slower with deeper concrete above. The trade-off is heat capacity, deeper concrete stays warm longer between cycles. We pick the underlayment thickness to balance response and retention for your use.
All of ours: polished, micro-topping, stained, plus tile and plank installed by a flooring contractor. The underlayment is engineered to take any finish above.
Not when it is engineered for the thermal cycling and the loops are properly insulated. We use products designed for heated-floor encasement and detail any expansion joints so the underlayment moves where it should.
We pour the underlayment and coordinate with the heating contractor who handles the tubing, manifold and boiler or panel side. The handoff is sequenced so the tubing is pressure-tested before and after the pour.

What Regina Homeowners Say About Their Heated Floors
Hydronic heated floor underlayment under polished concrete in the basement. Even heat top to bottom and the polish brings out a warm glow that feels great in winter.

★★★★★
Electric mat under micro-topping in the bathroom. Underlayment encased the mat perfectly, no cold patches, the floor is exactly the temperature we set.

★★★★★
They coordinated with our HVAC contractor on the pressure tests before and after the pour. Caught no issues but we knew the install was clean before the finish went on.

Emerald Park
★★★★★
The polished concrete over the heated underlayment is the best floor in the house. Warm in February, cool in July, and the polish is dead easy to keep up.
