PU Injection Resins
WEBAC® 1610
- Classic Line
Significant cracks appeared in the vaulted ceiling above the nave of St. Vitus Church in Erling / Andechs. Initial restoration attempts using cement grouting did not yield the desired results. Nor did the use of horizontal anchors to close the cracks result in sufficient stabilization.

The sustainable solution was ultimately achieved by injecting material from above, above the vaulted ceiling. WEBAC 1610 was used for this purpose—a PU injection resin with high-tensile strength properties that are tailored to the compressive and bending tensile strengths of the masonry. This allowed the cracks to be sealed structurally while simultaneously stabilizing the exterior walls.
Through targeted crack grouting, the historic vaulted ceiling was permanently secured and the structural integrity of the church was effectively stabilized.
PU Injection Resins
WEBAC 1610 is a high-strength PU injection resin whose compressive and bending tensile strength is specifically designed for structural bonding in masonry. When mixed with water, it foams slightly; however, under dry conditions, it cures without foaming into a compact, waterproof material. It is suitable for sealing, solidification, and structural bonding of building components, as well as for filling cavities/voids, and is specifically designed for use in masonry.
