ASTM D8109-17 PDF Download

The ASTM D8109-17 standard provides guidance on the selection and installation of chemical grout to seal leaks in concrete walls, floors, and ceilings. The standard focuses on the injection of through-wall cracks but can also be adapted for other voids contributing to water intrusion through concrete elements, such as cold joints, control joints, and penetrations.

It is important for all parties involved in the repair process to have a clear understanding of the limitations and iterative nature of the repair. The injection of chemical grout does not address the source of the leak but rather obstructs the infiltration of water at a specific location. It is common for water to subsequently appear at a different location that was previously dry. Therefore, periodic monitoring of the repairs is necessary, and additional repair installations may be required.

The standard is applicable to below-grade walls and slabs, but it does not specifically address the installation of grout in dynamic cracks or joints found in above-grade elements. Cracks in below-grade walls may also indicate structural distress, so a thorough assessment of the overall conditions and context should be conducted before implementing non-structural repairs.

The standard does not cover repairs intended to provide a seal against air leakage or air infiltration. Additionally, project-specific or environmental conditions may warrant the evaluation of curtain grouting as an alternative to crack injection.

While the standard does not address particulate grouts or epoxy as injection materials, it references other ASTM standards (F2304, F2414, and F2454) that provide general information on chemical grouting materials and methods used in sealing components of sewer systems, which may be of interest to those involved in waterproofing repair of building elements.
