Warm floors start with the concrete. We pour the slab that encases your hydronic or electric radiant tubing, creating an even heat distribution layer under polished concrete, micro-topping, tile or plank. The underlayment bonds to the substrate and finishes flat, ready for whatever surface you choose. Free written estimate included.
How Radiant Concrete Underlayment Shapes Floor Performance
Radiant heating systems depend on the concrete around the tubing to transfer warmth evenly to the surface above. When the slab has voids, soft spots or inconsistent density, heat radiates unevenly, creating cold zones and hot spots. The underlayment is the critical layer that makes the system work as designed.
We pour a self-leveling concrete underlayment that fully encases the radiant tubing with zero voids, bonds securely to the substrate below, and settles to a flat, dense, finish-ready surface. Whether your system uses hydronic loops (water through PEX) or electric mats, the encasement process is identical. The heating contractor manages the tubing and source; we manage the concrete.
Once cured, the underlayment accepts any finish: polished concrete for a hard, bright surface, micro-topping for a thin overlay, stained concrete for colour, or tile and plank installed by a flooring specialist. The heat flows through the underlayment to the finish, warming the room from the floor up.

Installation sequence
How Radiant Floor Concrete Gets Installed in Pittsburgh
Coordinate tubing layout
We work with you and your heating contractor to confirm the tubing path, loop spacing, manifold location, and the full coverage area for the underlayment pour.
Secure and pressure-test tubing
The tubing is fastened to the substrate or insulation board and pressurized to operating specs before the concrete goes in, catching any defects before encasement.
Pour self-leveling underlayment
Self-leveling concrete is placed around the tubing to the finished elevation, fully encasing every loop with no voids, then settling to a flat, dense, finish-ready surface.
Cure, test, and finish prep
The underlayment cures on schedule, the tubing is pressure-tested again to confirm no damage during the pour, and the surface is prepped for the finish layer above.
Finish options
Polished, Micro-Topping, Tile, All Work Over Radiant Concrete
The underlayment is engineered to support any finish that suits your space. Polished concrete over radiant underlayment is a popular choice in Pittsburgh basements and kitchens, delivering a hard, low-maintenance surface that feels warm underfoot in winter.
Micro-topping creates a thin, seamless finish layer; stained concrete adds warmth and colour. Tile and plank flooring lay directly on the underlayment as well. For uneven substrates, pair with self-leveling prep first to bring the slab into tolerance.
Hydronic vs electric, finish options, response time and coordination in Pittsburgh.
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 Pittsburgh 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.

★★★★★
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.
