Micropiles is often utilized in Just about any subsurface soil or rock given that they are often inserted using drilling products and coupled with numerous grouting treatments to form the bearing component.
Keller can combine our micropile technological innovation with a number of of our other floor modification techniques to fulfill unique or advanced project needs Value-properly and competently. Lines of micropiles spanned by wood lagging might be best where by excavation partitions are demanded in low headroom and various confined areas.
