Delete vacuuming exposes subslab sewers

Sometimes, a base water underneath a ground-installed slab may have depressions or other functional disruptions that require the sewer to be exposed. Repairs carried out from above the slab are expensive and difficult, but there is an affordable alternative that does not disrupt the use of the property: we suck the tunnels underneath the slab through a hole dug under the plinth, enabling the replacement and repair of the sewers from below. If necessary, the subslab gravel can be blown back under the slab.
