Concrete and Masonry in Sunland-Tujunga, CA

Most of what we pour and lay up here falls into two groups. Poured work covers driveways, walkways, patio slabs, steps and pool decks. Mortared work covers block walls, brick, stone veneer, seat walls, pilasters and retaining walls. On a typical foothill property both show up together, since a slab behind the house usually needs a wall or a set of steps to meet the grade above it. We scope the base, the steel, the drainage and the finish before anything gets ordered.

Decomposed granite that came down from the San Gabriels drains very fast, which helps under paving because water does not sit and soften the subgrade. The catch is that it stays loose and gravelly until it is compacted properly, and it hides rock. We excavate to depth, pull out what will not compact, then build and compact base in lifts rather than dumping it in one pass. Where we hit rock that will not break cleanly, we work the slab edge or the footing around it instead of fighting it.

Yes, and steps are one of the most common requests on the steeper properties up here. The work is in the layout more than the pour. We measure total rise, divide it into risers that stay consistent from bottom to top, and set the treads so the walk stays comfortable rather than turning into a scramble. Each flight gets a compacted base with steel tied through it, and on a real slope we tie the flight into a wall or a footing so the run is not resting on fill.

Because the wall is holding back a hillside, not just edging a planter. Above a certain height the City requires a design stamped by an engineer, and that design sets the footing size, the vertical rebar schedule, which cells get grouted solid, and how the wall carries the load behind it. On the steep lots common here that math matters. A wall built by eye on this ground will lean, then crack, then fail, usually after a wet winter when the soil behind it is fully loaded.

Sunland-Tujunga is part of the City of Los Angeles, so plan check and inspection go through Los Angeles Building and Safety rather than a county office. Freestanding block walls and retaining walls above the height threshold require a permit, and retaining walls require an engineered design with it. Inspections generally land at the footing stage and again before the wall is closed up, which means the schedule has to leave room for them. We handle that process and build to what the approved plans show.

No. The apron, meaning the section between the curb or sidewalk and your property line, sits in the public right of way, so it is handled separately from the slab on your own land. That portion is City property and carries its own requirements for how it gets poured and finished. On the older foothill streets around here, curb and gutter conditions vary block to block, so we look at what is actually in front of the house before deciding how the apron ties in.

Thickness follows what will drive on it. A residential driveway carrying cars and the occasional delivery truck gets poured heavier than a garden walkway, and it gets steel on chairs rather than mesh dropped onto the dirt. On a steep approach we also watch the transition at the street and at the garage, since a driveway that changes angle too abruptly will scrape bumpers no matter how well it was poured. Base compaction under that slab does as much work as the concrete above it.

Rebar or welded wire mesh, and the important part is where it sits. Steel lying on the subgrade does nothing at all. It has to be lifted on chairs so it ends up inside the slab where the tension is. We size and space the steel to the use of the slab, tie it, and set expansion material where the pour meets a foundation, a wall or an existing slab so the two are not locked together. Dowels go in where a new pour has to move with an old one.

Concrete shrinks as it cures and it will relieve that stress somewhere. Control joints give it a planned place to crack, cut deep enough and spaced to the slab, so the break follows a straight tooled line instead of wandering across the middle of the patio. Random cracking usually traces back to no joints at all, joints cut too shallow or too far apart, base that was never compacted, or a slab that dried out too fast. Curing it properly matters as much as the mix does.

Broom finish is the workhorse: textured, slip resistant, easy to repair, and it stays in the background. Exposed aggregate reads more natural and suits the foothill setting, since the stone in it echoes the rock already in the ground here. Stamped concrete gives you a pattern at slab cost and takes color well. Integral color goes through the whole pour instead of sitting on the surface, so a chip does not flash gray. Sealers deepen the color and add protection, though they need renewing over time.

It starts below grade with a footing sized to the wall and to the soil, with vertical rebar set into it at the spacing the plans call for. Block goes up over that steel, horizontal bar is laid into the courses where it belongs, and the cells containing rebar are filled solid with grout so the wall behaves as one reinforced unit instead of a stack of block. Once it has cured we can leave it plain, stucco it, or face it with stone veneer or brick.

Water pressure is what pushes walls over, so the back of the wall gets built to let water escape. Gravel backfill goes against the stem, a perforated drain pipe sits at the base of that gravel and is carried out to daylight, and weep holes give any remaining water a route through the face. On these foothill lots the runoff coming down the slope during a storm is serious, so we also plan where that water goes once it leaves the pipe rather than dumping it at a neighbor.

It does. This is a wildland interface area, and the zone closest to the structure is exactly where you want the least fuel. Concrete, block and stone do not burn, so a walkway, a patio slab or a low wall ringing the building gives you defensible space that also happens to be usable outdoor area. We often lay out paving and seat walls to hold that clear band tight around the house, then push planting beyond it. That is a decision worth making early rather than retrofitting later.

Yes. Seat walls are usually block cores with a cap and a face, and they double as low retaining at a small grade change, which is useful on the terraced yards up here. Pilasters give an entry or a driveway gate something substantial to land on and need their own footing and steel. Stone veneer can go over new block or over sound existing walls once we check the substrate. The trick is matching stone to the house and to the surrounding foothill rock rather than picking from a chart.

A pool deck is a slab people walk on barefoot and wet, so the finish gets chosen for grip first. It also has to shed water away from the pool rather than back into it, which means slope and joint layout are planned around the coping and the deck drains before anything is formed. We keep the deck isolated from the pool shell so the two can move independently. On a sloped lot we also follow where the runoff coming off that deck finally ends up.

They solve the same problem in different ways. Poured concrete and mortared masonry are monolithic, so they hold a grade change, span a base well and can carry steel. Dry laid pavers sit on compacted base and sand, flex a little, drain through the joints, and can be lifted and reset. On a steep or terraced foothill lot, poured work usually wins wherever structure and grade are involved, while paving is a good answer on the flatter areas. Plenty of yards here end up with both.

One licensed contractor, start to finish. Daniels Landscaping stays accountable for the work. The people who dig and form the footing are the same people who set the steel, run the pour, cut the joints, lay the block and finish the veneer. That matters most on this kind of work, because concrete and masonry are unforgiving once they set, and quality comes from a crew knowing what the last step was and what the next one needs. You see the same faces on your property every day the job runs.

Call Daniels Landscaping at (818) 443-9300 and we will come out to the property. During the visit we walk the grade, look at the soil and any rock showing at the surface, check where water runs in a storm, and talk through what you want poured or built. You receive a free written estimate spelling out scope, base, reinforcement, drainage and finish, so you can compare it honestly against anything else in hand. We are licensed in California under license number 1138709.
