Void filling

Void filling is a geotechnical technique used to fill voids or empty spaces within a structure. Void filling is typically used in masonry or concrete structures. The process is similar to slab lifting.

It starts by drilling holes in the concrete structure. Afterwards, a specialty resin is injected directly into the structure. GEORESIN is designed specifically for filling cavities in concrete walls and similar structures.

GEORESIN is an expanding foam that generates heat when installed. As a result, it’s essential to perform void fills in a layered approach to ensure that the heat dissipates safely. By applying the expanding foam, you can eliminate any movement in the structure while providing extra support.

Our specialty resins for void filling in concrete structures offer many advantages

Lightweight: GEORESIN is an expandable foam and therefore significantly lighter than traditional filler materials, reducing the overall weight of the structure. This can be particularly beneficial in areas with soft or weak soils, where the weight of traditional filler materials like sand or mud can cause settlement and other structural problems.

Faster installation: GEORESIN can be applied quickly and easily, reducing installation time and labor costs.

Improved stability: An expandable void filling foam provides excellent support and stability to the surrounding concrete, helping to prevent cracking and other structural issues.

Reduced material waste: An expandable foam can be applied with utmost precision to fill voids of any size and shape, reducing material waste and eliminating the need for additional filler materials.

Water resistance: GEORESIN is highly water resistant, which helps prevent moisture-related damage to the surrounding concrete while improving the overall durability of the structure.

Using an expanding void filling foam offers many advantages, especially compared to more traditional methods used for filling voids in concrete structures such as sectional repair and mud-jacking.
