DEALING WITH A HIGH WATER TABLE

DEALING WITH A HIGH WATER TABLE

There are varying soil types in Christchurch and with the low lying geographical nature of many areas of this city you don’t have to dig down far to reach water. This presents a challenge when digging down to excavate around foundations and you discover the water table. Areas such as South Brighton, Merivale, Parklands and Shirley are prone to this. Factors such as high tide and extended periods of rain can affect how much water is in the ground at any point in time.

At SmartLift we have developed methods and procedures to allow us to still get our jacking pads installed and successfully level homes. It involves pumping water into trucks, using water blasters and giant vacuum pumps to extract liquid soil but concrete can still be poured and the chemical nature of it allows it to harden and cure.

Some home owners use this opportunity to raise their foundations another 100- 200 mm and get it above any flood threat that might exist or as a precautionary procedure. This is a perfect time to consider this as an option. Your concerns can be discussed with us when we make our site visit and we can have our engineers look over your floor levels and geotech report and offer you advice on the best way to proceed.

Regardless of how messy the actual job is, we still take pride in leaving your property in a neat, clean and tidy state – it’s almost like we weren’t there. Your builder or project manager will have no trouble finishing off the repair work when we leave. Even in challenging conditions we can successfully level most homes within 15 working days.
