Step 1
Drain the spring box. If the damaged spring box was originally constructed with a drain pipe and valve, you will have no difficulty draining the water and repairing it. If the box does not have a drain pipe or if the leaks are below the water level of the drain pipe, you must siphon the water out. In this case, drop one end of the garden hose to the bottom of the spring box and put the other end outside the box below the foundation of the box. Manually suck water through the hose until it begins to siphon itself. If the volume of water is too great for the water hose to siphon the water out, you will have to use a water pump.
Step 2
Mix an appropriate amount of water and concrete in the bucket. Trowel the concrete onto the spring box's cracks and damaged areas on both the inside and outside of the box.
Step 3
Attend to the spring box while the concrete is curing if you had to siphon the water out. If the hose clogs or stops siphoning, or if the pump stops working, there is a chance the spring water could damage your work. Concrete usually sufficiently cures in five or six hours.
