Base preparation
Excavation, compaction in lifts and the correct base depth for the use and soil.
Hardscaping • Livermore, California
Hardscaping in Livermore & the Tri-Valley
Patios, walkways, entries and outdoor living space built on properly prepared base — the part that decides whether it stays flat.
Paver and stone work fails from below. Insufficient base depth, poor compaction and no plan for water are why patios settle, joints open and edges wander within a few years.
We excavate to the depth the assembly needs, compact in lifts, set drainage and edge restraint, and then lay the pattern with consistent joints and clean transitions into the house, planting and grade changes.
What the work includes
Handled properly, in the right order.
Drainage
Slope and drain placement planned so surfaces shed water away from structures.
Layout and pattern
Pattern set out from the house lines so cuts land in sensible places and joints stay tight.
Walls and structures
Retaining walls, seat walls, steps and outdoor kitchen framing built to hold their line.

Our process
From vision to completion.
The same four stages on every project, so you always know where things stand.
- 01
Consultation
We walk the space, listen to how you use it and define scope, priorities and realistic budget ranges before anything is promised.
- 02
Planning
Selections, sequencing, materials and schedule are documented so expectations are aligned before the first day of work.
- 03
Construction
Clean, protected job sites and coordinated trades. Progress is communicated and quality is checked as the work advances.
- 04
Final Walkthrough
We review the finished work together, address every detail on the list and hand over a project that is genuinely complete.
Questions
Straight answers.
Why do paver patios sink over time?
Almost always inadequate base depth or compaction, or water with nowhere to go. Both are preparation decisions made before any paver is placed.
Do you build retaining walls?
Yes. Height, soil and drainage determine the wall type, and taller walls may require engineering and a permit, which we handle.
Can you build an outdoor kitchen or fire feature?
Yes, including the framing, veneer, gas and electrical coordination those features need.
How does hardscaping tie into the rest of the yard?
We set grades and transitions for hardscape and planting together, so the patio, walkways and beds meet cleanly instead of being reworked later.
