How fast can you mobilize to a job?
Lead-times are based on project specifications and location. Please call or email us with the details and we will let you know a schedule date. Expedited lead-times may also be available!
Is drilling through rock a problem and are there additional costs?
Drilling through solid rock is actually preferred! United Drilling has specialized equipment that allows us to drill quickly and efficiently through all natural ground conditions.
Access is a big concern; will your inside rig be able to obtain entry to the elevator hoistway?
Our InsideAir™ drill rig can fit through a standard 30” doorway. It was designed to go “anywhere a wheel-chair can go”. Read more about how it can accomplish this on our Inside Drilling Article.
The site is concerned about a high water table; what can be done?
United Drilling defines a high water table, in terms of hydraulic elevators, as when the static water level is above the pit floor. In this scenario we would highly recommend installing a steel water-tight liner at the time of drilling. United Drilling guarantees water will not come up from the inside of the steel liner. The water-proofer onsite will guarantee the water does not come up the outside of the steel liner. Please read our Steel Liner Installation Article for further information.
Do you install a casing to the full depth of the hole?
United Drilling utilizes ¼” wall steel casing to drill; this casing will extend the entire depth of the hole OR until solid rock is encountered. Should job specifications require the hole to be cased full depth a steel liner may be purchased.
Will you install a bottom on the steel casing when you drill?
United Drilling drills by driving steel casing into the ground; the spoils (dirt) are then removed from the inside of the casing. For this reason we cannot install a bottom on the drill casing or we will not be able to advance it into the earth. If you need a bottom on the casing a steel liner must be purchased.
Will you make noise?
Yes. We will make noise. The rig we are using and ground formations we encounter will dictate the decibel level. Inside drilling is the rig typically questioned when noise is a concern. The loudest the rig has been recorded is 128dB; this intense volume occurs when the drill casing is being driven into the ground. Duration of this volume typically ranges from 15-45 minutes in increments throughout the day; the number of expected increments is based on the depth of the hole.
Are you sure you can drill at this location?
United Drilling has never been unable to complete a project. We give you a firm price to drill the hole and, unless we hit something unnatural, the drilling price will not change. If you would like to see a map of hole(s) we drilled close by, just send us an address and we will send you a link. You may be surprised we drilled right next door…
I am replacing a hydraulic elevator cylinder; any suggestions?
United Drilling has worked on over 4,000 modernization projects. While every project is unique you should have the confidence that the crew completing the work has the knowledge and resource to combat any issue that may arise. Please review our ‘Hydraulic Cylinder Replacement’ article to help you in preparing. If you are already under-going a replacement and have run into issues contact us to discuss a solution.
Will you be able to access the drilling site with your truck rig?
Please note our truck rig is roughly the size of a concrete truck and is equipped with rubber tires, not tracks. Please refer to our truck schematic for dimensions as the truck requires a 35’ by 12’ level area as well as 55’ of overhead clearance.
