We present a full set of numerical tools to extract Galaxy Cluster pressureprofiles from the joint analysis of Planck and South Pole Telescope (SPT)observations. Pressure profiles are powerful tracers of the thermodynamicproperties and the internal structure of the clusters. Tracing the pressureover the cosmic times allows to constraints the evolution of the clusterstructure and the contribution of astrophysical phenomena. SPT and Planck arecomplementary to constrain the cluster structure at various spatial scales. TheSPT cluster catalogue counts 677 cluster candidates up to redshift 1.7, it is anearly mass limited sample, an ideal benchmark to test cluster evolution. Wedeveloped a pipeline to first separate the cluster signal from the backgroundand foreground components and then jointly fit a parametric profile model on acombination of Planck and SPT data. We validate our algorithm on a sub-sampleof six clusters, common to the SPT and the CHEX-MATE catalogues, comparing theresults with the profiles obtained from X-ray observations with XMM-Newton.
