Case of the Day – Heated Slab-on-Grade Ramp Reconstruction in Montreal

Introduction

In Quebec, exterior concrete ramps face harsh conditions — freeze-thaw cycles, water infiltration, and de-icing salts.

Over time, these factors lead to cracking and deterioration.

For this project in Montreal, Florcon was commissioned to fully rebuild a slab-on-grade ramp with an integrated hydronic heating system, ensuring safety, comfort, and long-term durability during winter.

Project Scope

The project involved:

• Full demolition of the deteriorated concrete ramp;
• Subgrade preparation and drainage improvement;
• Installation of rigid insulation to reduce heat loss;
• Integration of an in-slab hydronic heating system;
• Pouring of a new reinforced concrete slab with a non-slip finish.

Execution Steps

1️⃣ Demolition and Preparation

The old ramp was completely removed, exposing a solid base.

The subgrade was compacted and leveled to ensure proper drainage.

2️⃣ Insulation and Reinforcement

Rigid insulation was installed under the new slab to reduce thermal loss and maximize heating efficiency.

Steel reinforcement was added to ensure long-term structural strength.

3️⃣ In-Slab Heating System

A hydronic heating system (hot water circulation) was embedded directly in the concrete slab.

This allows the ramp to remain completely snow-free and safe throughout the winter, without the use of salt or manual snow removal.

4️⃣ Concrete Pour and Finishing

Concrete was poured around the heating pipes and finished with a non-slip surface texture.

The mix was designed for freeze-thaw durability and resistance to de-icing products.
