PROBLEM TO BE SOLVED: To provide grouting equipment and a grouting method, which enable a proper injected amount of soil improvement material to be injected into ground by employing a simple constitution without use of an expensive member. SOLUTION: Characteristically, this grouting equipment 10 includes: an injection section 5; a storage section 2; a pumping means 3; a detection section 6; a distribution section 4 which distributes the soil improvement material between the injection section 5 and the storage section 2 so that the injection ratio of the amount of soil improvement material, flowing to the side of the injection section 5, to the total amount of soil improvement material pumped by the pumping means 3 can be changed within the predetermined range of the ratio; and a control section 7 which includes an injection ratio increasing section 71 outputting a control signal for increasing the injection ratio to the distribution section 4 when a flow rate is a predetermined amount or below and a pressure is a predetermined one or below, an injection ratio decreasing section 72 outputting a control signal for decreasing the injection ratio to the distribution section 4 when the flow rate exceeds the predetermined amount or the pressure exceeds the predetermined one, and an injection ratio maintaining step outputting a control signal for maintaining the injection ratio, when the flow rate is equal to the predetermined amount and the pressure is the predetermined one or below.
