Orders can be placed via telephone, fax, email, or other mail delivery services. Before processing each order a customer service specialist will review all requirements for accuracy and completeness. You will be contacted if additional information is required. If you have previously obtained a quotation please reference the quote number in your order. If you are purchasing items that you have purchased from Geotech before, please reference the previous Geotech sales order or invoice number. Pre-qualified buyers may purchase on open account, otherwise we accept Mastercard, Visa, or cash.
