WHAT IS THE BEST MATERIAL TO RAISE CONCRETE WITH?
- The choice of the best material to raise concrete, also known as concrete leveling or slabjacking, depends on various factors, including the specific project requirements and the desired characteristics. Two common materials used for this purpose are:
- Polyurethane Foam: Polyurethane foam injection has become popular for concrete leveling in recent years due to its advantages:
- Lightweight: Polyurethane foam is lightweight, reducing the load on the underlying soil.
- Fast Cure: It cures quickly, allowing for a rapid repair process.
- Controlled Expansion: The foam expands to fill voids and can be precisely controlled to lift and level the concrete slab.
- Water Resistance: It is resistant to water and won't erode or wash out over time.
- Minimal Disruption: The equipment used for polyurethane foam injection is less invasive, causing minimal disruption to the surrounding area.
Cement Grout: Cement-based grout is a traditional method for concrete leveling. It offers stability and durability but has some limitations:
Rigid: Cement grout is rigid and may not accommodate future soil settlement or movement.
Heavy: It can add significant weight to the void, potentially compressing the underlying soil.
Slower Cure: Cement grout generally takes longer to cure than polyurethane foam.
The choice between these materials depends on the specific circumstances of your project, such as the size of the void, the desired speed of repair, and budget considerations. Consulting with our professional technicians is essential to determine the best material for your concrete raising needs. We can assess the situation and recommend the most suitable method and material to achieve a stable and long-lasting repair.
