Application Situation

A crane's base was seeing the heads of the bolts holding it down beginning to break off.

Application Method

First, 48 new holes were drilled to install newly fabricated bolts. Then the skid was positioned over the concrete base, secured and aligned with 4 metal bars in 4 points around the perimeter of the skid, and positioned on top of the concrete base. Belzona 4111 and Belzona 4151 were then mixed and injected into each of the holes. Anchor bolts were inserted, and excess of product was used to fill the annular space under the equipment.

Belzona Facts

A traditional approach to problems like this one would require at least 45 days to demolish the base of the crane and reconstruct it again. Whereas the Belzona solution came at half the cost of the traditional method and promised to return the crane back to service in 7 days. The customer was very impressed with the application and one year later reported that the bases were in perfect condition.
