Grain Silo Repairs - Sussex As you can see we lucked into a good week of weather to repair these grain silos. Access and egress from inside the silos was safe and made the project less of challenge. The drying floors sat up about 500mm from the concrete floor and had to removed. The wooden supports were also removed to make the job a lot more doable Once all the floor was removed, the damage was very visible. The internal wall floor corner had rotted out and was letting rainwater and vermin in from the outside. After sandblasting the corrugated tin wall and concrete floor, we applied our fibreglass lining system. This ensured the grain in these silos was never going to get wet again and also protected the stock from vermin.
