The problem

What we found

Cracks at the base of grain bins were allowing water to enter the silo, causing grain rot and financial loss. Previous attempts using surface sealants and even spray foam coatings failed to stop water migration through the concrete, so intrusion continued.

The solution

How we repaired it

We removed the failed spray foam and thoroughly cleaned the cracks. We then drilled injection ports and performed pressure grouting using a water-activated polyurethane grout. By pre-wetting the crack, we encouraged the grout to chase water through the crack path, creating a sealed, waterproofed crack from within the concrete rather than a superficial coating.

The result

What changed

Water intrusion was addressed using an engineered pressure grouting method appropriate for active conditions. The sealed cracks helped protect stored grain and restore reliable performance of the silo.

Have a similar problem?

Let us test what is underneath.

We inspect the site and measure the soil before recommending a repair.
