Resin injection underpinning is a modern and efficient method to address various foundation problems. When your building’s foundation soils have deteriorated or the bearing capacity has reduced due to various factors, it can lead to problems like house subsidence, sloping floors, cracking in walls, jammed doors, concrete slab repairs, structural issues, and even concrete cancer.

Resin injection underpinning involves injecting a polyurethane resin into the ground beneath the building foundation. The resin expands and hardens, filling holes and voids, improving the soil’s strength and stability, and lifting the concrete slabs back to their original position. This method is also known as slab jacking or concrete lifting.

Resin injection underpinning is a sophisticated process that involves the use of a two-part polyurethane resin. Here’s how it works, step-by-step: 

1. Assessment: The first step involves thoroughly assessing your property with experienced professionals. R+R will identify the areas with foundation issues and determine the best locations for resin injection. We’ll examine signs of structural distress, such as wall cracks, uneven floors, or doors and windows that stick. This is particularly important in the case of unlevel buildings.
2. Preparation: Once the problem areas are identified, our team prepares for the crack injection process. This involves drilling small holes into the concrete slab at strategic locations. These holes serve as the access points for the resin injection.
3. Injection: We’ll prepare the two-part polyurethane resin. The two components of the resin are stored separately until the time of injection to prevent premature reaction. At the time of injection, the two parts are mixed, and we inject the resulting mixture into the ground through the drilled holes. This is known as a concrete crack injection.
4. Expansion and hardening: Upon contact with the soil, the resin undergoes a chemical reaction that causes it to expand. This expansion fills any voids in the soil, displaces loose soil, and compacts the surrounding area. The resin then hardens, providing a solid, stable base that increases the soil’s bearing capacity. This process can be part of ground improvement strategies.
5. Lifting and stabilising: As the resin expands, it exerts an upward force on the concrete slab above it. This force lifts any sinking or settling slabs back to their original level, effectively rectifying problems like uneven floors. The hardened resin stabilises the soil, preventing further movement and ensuring the long-term stability of your property’s foundation repairs.
6. Finishing: After the resin has fully hardened and we’ve made all necessary adjustments, we’ll patch the drilled holes and clean the site, leaving minimal evidence of the work done. This process is part of our comprehensive concrete repair services.
7. Structural repair: Resin injection is a commonly used method for structural repair, especially in cases of cracked concrete or subsidence damage.
8. Void filling: Resin injection effectively fills voids within concrete structures, improving their stability.
9. Leak repairs: Resin injection can be used for leak sealing and water leak repairs in basements, walls, and floors.
10. Protective coatings: Resin injections can enhance protective coatings on concrete structures, preventing further damage.
11. Chemical underpinning: Resin injection is a type of chemical underpinning used to stabilise and reinforce foundations.

Resin injection underpinning is a highly effective method for addressing various foundation problems. It offers a fast, minimally invasive, and long-lasting residential solution to subsidence, uneven floors, and concrete cracks.
