Excavation contractor in Rialto, CA
Rialto has thousands of homes built in the 1950s, 60s and 70s on lots that are deeper than anything built today. Verdemont Excavation refers Rialto requests to a licensed contractor who sees the same three jobs over and over here: an ADU pad in the back of a long yard, a sewer lateral that has finally given out, and a pool dig or pool fill in.
Laterals from that era are often clay or Orangeburg, and by now many have roots, offsets or collapsed sections. Replacing one by open trench usually runs $4,500 to $12,000. If you are adding an ADU anyway, it is often worth replacing the main lateral at the same time so both units drain through new pipe.
Rialto also has commercial and industrial site work on the land around the former Rialto Municipal Airport and along the freeway corridors. Small commercial pads, utility trenches and parking lot grading for local businesses are part of what the contractors we refer take on, alongside homeowner work.

Fill in the pool the right way the first time
Pool fill ins are common in Rialto as older pools reach the end of their life. If there is any chance you will build an ADU or a room addition where the pool sits, pay for full removal with engineered backfill and compaction reports. A partial fill in is cheaper, but that ground is hard to build on later.
Rialto questions
How much does pool removal cost in Rialto?
A partial fill in, where the shell is broken up and buried, runs $7,000 to $14,000. Full removal with engineered backfill runs $14,000 to $30,000 and leaves ground you can build on. Rialto requires a permit for either.
Should I replace my sewer lateral before adding an ADU?
If the line is original clay or Orangeburg, usually yes. A camera inspection shows its condition, and replacing it while the yard is already open for the ADU saves a second dig.
Do you handle commercial site work in Rialto?
The contractors we refer take small commercial pads, utility trenches and parking lot grading. Large warehouse projects go to bid through general contractors and are outside what we handle.
What does an ADU pad cost in a Rialto backyard?
Typically $4,000 to $9,000 for the pad and footings on flat ground. Long yards with gate access are easy; tight side yards add hours.
