Everything To Know About Using SPF For Concrete Slab Lifting
Concrete is one of the most durable buildings and pavement tools available for any property. It has great pounds-per-inch carrying capability, allowing vehicles and heavy foot traffic to traverse roads for decades. Plus, it does not cave into moisture thanks to its protective paint.
However, its seamless and leak-less design makes it difficult to remove without causing structural damage to other areas. A single crack can destroy an entire concrete slab. Luckily, spray polyurethane foam (SPF) jacking is one of the best tools for lifting up concrete slabs without breakage.
The Tools Most Service Providers Use
Every specialist knows their tools. Ener-Spray’s specialist SPF applicators use only the latest technologies in rendering their concrete slab lifting work. They can achieve massive results while ensuring their employees’ safety and proper equipment usages in the field.
Most teams use top-tier equipment in the field, such as these :
- Mechanical Purge Guns: These do not guarantee material crossovers, which is a common problem among most air purge guns
- A Hammer Drill
- 6mm Polyester Sheets to prevent SPF concrete staining
The Steps to Lifting Concrete Slabs
Use the hammer drill to dig holes inside the concrete. It’s essential to use high-quality hammer drills to ensure consistency and clean drills. It’s crucial to remember that concrete can have a broken structural composition with improper drilling techniques.
Trained SPF applicators have full knowledge of using drills to serve as injection entry points. While they’re not engineers, their training under certified structural engineers and SPF applicators guarantee they can provide the best results for any project.
All SPF applicators use high-quality SPF injectors that dig straight into each concrete hole, filling its underside with enough closed-cell SPF. The liquid will seep through a significant area, allowing it to push with great strength once it dries and cures after 48 hours or beyond.
A complete upwards push of a wide concrete area allows it to lift without any structural damages. This method is more effective than breaking a concrete panel and using a piece of powerful mechanical equipment to lift the slab.
Once the SPF dries, applicators will use levelers to measure any differences in slab-to-ground height. Some projects might require more SPF applications than others to fulfill their goal.
Mortar Mix Patch Up
Quick-set mortar mixes do an excellent job of patching up holes at each injection site. Doing this is handy, especially if you’re dealing with possible rains or excessive moisture on the roads typical in residential areas. Patching up the ground with mortar guarantees your SPF physical protection against moisture, debris, and other contaminants in your work area.
It’s essential to work with professional SPF applicators for any slab-building work you may need.
