To effectively repair exterior cracks in a building, follow these steps:

• Excavate down to the footing and clean the surface to prepare the work area.
• Drill injection cavities into the wall to access affected areas.
• Install high-pressure injection ports on the wall to control the flow of repair material.
• Systematically pump polyurethane resin into the cavities to fill the cracks and reinforce the structure.
• Apply Resisto brand elastomeric membrane to the repaired surface to ensure a waterproof barrier.
• Install Delta-MS brand dimpled membrane to promote drainage and moisture protection.
• Backfill the hole with appropriate material and compact the soil thoroughly to stabilize the repaired area.
