The 100+ year old VCP septic line in the Winooski Block building began to fail, and we were called in to assess the cause of the problems and find the most cost-effective solution. We excavated for and replaced the existing lines in three of the unit’s basements. On the exterior, we excavated down to where the building main meets the city main, replaced the line under the foundation and joined it to the city main. We also installed cleanouts. We then hand-dug 12-15″ out of the entirety of the final basement to gain headroom, installed a vapor barrier, and poured a concrete slab.
