Case Studies
Top Hat repair solves a difficult excavation problem
Drain Alert was asked to investigate a damaged 100mm private connection into a 225mm public - an excavation to 2m deep was considered impractical. The agreed solution was a Top hat repair resulting in a smooth transition and strengthening of the inherent defect. Partner, E R Technical Services, is currently promoting this technique as one of their proactive new products.
