ANTI-HEAVING

Heave is the upward movement of a structure due to water pressure and underlying soils that expand or swell. The major reason for this is a high groundwater level and/or freezing soil. Heave can occur in Tunnels, Tunnel ramps, Underpasses or basements of buildings. The common approach is to work with raft foundations were the weight is higher than the uplift forces. In buildings with basements, a dewatering system is often used to reduce uplift forces. The groundwater management has to be in placed when the above structure cannot create enough weight to withstand the heave. Both approaches are often more costly and/or time consuming than using Ischebeck Titan Micropiles to take care of these forces.

ANTI-HEAVING IN TUNNEL & TUNNEL RAMPS

Ischebeck TITAN Hollow Bars used on a ramp in Dubai for an under-pass.  Instead of using 3 ft rock foundation, they used a 1 ft concrete slab.

ANTI-HEAVING IN BASEMENTS

Ischebeck TITAN Hollow Bars are commonly used as tension piles to secure excavation pits against heaving.

DRILLING THROUGH WATER

Underwater drilling is a really useful technique to drill through water bodies. The piles are placed before pumping out the water to speed up construction and to limit the time of pumping water out of the pit.

DRILLING THROUGH SOIL

If you are building a structure such as basement, tunnel or tunnel ramp close to a body of water or close to area with high ground water level, it is necessary to drill the piles first  before the excavation to limit the use of pumps. Pumping water may cause other buildings to have unexpected settlements.
