Unilock Construction in Los Altos Hills, CA | Iron Beam Contractors
We’re an independent hardscape crew that installs, repairs, and rebuilds Unilock paving systems across the hillside properties of Los Altos Hills. We’re not authorized or sponsored by Unilock – we earn the work on installation quality and site-specific engineering. The one thing that sets our Unilock work apart in Los Altos Hills is that we treat every paver field and retaining wall as an engineered structure on difficult terrain, not a flat-lot installation. Call (833) 756-5936 for a free estimate on your project.
Why Los Altos Hills Residents Choose Us for Unilock Service
Nolan Driscoll grew up learning what happens when you build on clay and grade without understanding how water moves through soil. He brought that hands-on structural background to Iron Beam Contractors, and it drives how we handle Los Altos Hills General Contractor Unilock work: one contractor, every phase, specified for longevity. We know the Unilock profiles – Brussels Block, Beacon Hill Flagstone, Brussels Dimensional Stone – and we know what goes underneath them, because the base and drainage matter more than the brand name on the block.
When we open up a failed paver driveway or a leaning retaining wall in Los Altos Hills, we don’t guess. We check the base depth, the geogrid placement, the drainage aggregate, and the grade. Most problems we find start below the paver, not on its surface. That’s why homeowners who have had one bad paver installation call us the second time around.

Common Unilock Construction Problems We Solve in Los Altos Hills
- Edge sloughing and rutting on steep private-access driveways. Los Altos Hills driveways often double as access roads with serious grades. When an Unilock Brussels Block driveway apron was set on a base too thin for truck loading and slope, the edges break down and wheels carve ruts. We rebuild with a thicker graded aggregate base and proper edge restraints so the field holds its line.
- Efflorescence and joint-sand washout after the first heavy rain. Wet winters saturate hillside lots here, and uphill runoff drains across paver fields. A poorly sloped patio or driveway loses its polymeric joint sand in one season, leaving gaps the weeds love and a white mineral haze on the block face. We re-slope where possible, re-sand, and seal where it makes sense.
- Retaining-wall block shifting or bulging. Brussels Dimensional Stone courses built without geogrid and drainage aggregate behind the wall will push out on saturated Los Altos Hills clay. We see this same failure pattern across the 94022 hills every spring. The fix is a rebuild, not a face patch.
- Paver settlement and lippage over expansive clay. The clay under Los Altos Hills shrinks in dry summers and heaves after winter saturation. That movement reads as rocking units and uneven joints across an Unilock patio or walkway. A proper base with the right aggregate depth absorbs most of that movement before it reaches the surface.
- Driveway aprons that no longer handle the grade. On steep Los Altos Hills approaches, a standard residential paver base fails years early under vehicle load and braking force. We routinely rebuild these aprons with a stronger structural base and better edge confinement.
Unilock Service in Los Altos Hills: What Local Conditions Mean for Your Equipment
Here’s the checkable fact that shapes every Unilock job we do in Los Altos Hills: the town’s zoning enforces large minimum lot sizes and strict hillside/slope limits, which means a retaining wall here is a permitted and engineered structure, not a decorative border. Drive around the wooded lots off private lanes in the 94022 hills and you’ll see Unilock repair in Los Altos style Brussels Dimensional Stone walls holding back serious grade. Over a certain height and slope, Los Altos Hills requires engineering and drainage design before a single block goes down. That’s a completely different job from the low garden walls common in flat neighboring towns. If the structure makes sense on paper, it’ll hold in the field. If it doesn’t make sense on paper, we fix it before we touch a beam – or a block.
Unilock Models & Products We Service in Los Altos Hills
We install and rebuild Unilock Brussels Block for driveways and patios, Beacon Hill Flagstone for irregular flagstone-look surfaces, Brussels Dimensional Stone for retaining walls, and Copthorne or Town Hall profiles for traditional driveway aprons. When extending or replacing part of an existing field, we use genuine Unilock units and matching edge restraints so the new work blends with the old. On the base side, we use quality graded aggregate and polymeric joint sand – the underside is what actually determines how long the top looks right. For Los Altos Hills projects, we keep standard profiles on hand or order quickly from nearby supplier yards, which shortens turnaround on Mountain View Unilock service rebuilds.

FAQs – Unilock Construction in Los Altos Hills
No. Los Altos Hills enforces hillside/slope limits, and a retaining wall over a certain height or on a steep grade must have engineering and drainage design before permitting. We’ll tell you if your project crosses that line and coordinate the engineering. Call (833) 756-5936 and we’ll walk the site to check.
The base under your Unilock driveway was likely set too thin for the grade and the vehicle load on that section. Steep Los Altos Hills approaches put braking and acceleration force through the pavers into the base, and a residential-depth base fails early under that stress. The fix is rebuilding that section with a deeper structural aggregate base and stronger edge restraints.
The clay expands and contracts through the seasons, which can cause paver settlement and lippage if the base wasn’t built to absorb the movement. Proper base depth and drainage aggregate underneath the Unilock field is what prevents most of that surface movement. Call (833) 756-5936 for a site assessment and quote.
Yes. We use genuine Unilock units and matching edge restraints when extending or repairing an existing field, so the color and profile blend with what you already have. If the original line has shifted or weather-aged, we’ll pull samples and get you the closest current match.
In Los Altos Hills, a paver driveway typically runs $7,000 – $18,000. Steep grades, long private-access runs, and difficult truck access push that number toward the higher end. Call (833) 756-5936 for a free estimate – we’ll give you a written line-item quote before anything starts.
