Concrete and Masonry in Tarzana, answered
The questions we hear most from Tarzana homeowners.
A concrete and masonry project covers the poured and mortared work around a home. On the flatwork side that means driveways, walkways, patio slabs, front steps, pool decks, and equipment pads. On the masonry side it means concrete block walls, seat walls, pilasters, brick or stone veneer, and engineered retaining walls. In Tarzana the mix depends on where you sit. North of Ventura Boulevard the work leans toward flat slabs and driveways, while the sloped lots to the south usually need retaining walls and terraces. We scope the whole yard before we pour anything.
Yes. South of Ventura Boulevard the ground climbs toward Mulholland, and those hillside lots are where retaining walls earn their keep. A masonry retaining wall holds because of how it is built, not because of its face. We pour a wide footing below grade, set vertical rebar into it, stack reinforced block over that steel, and then fill the cells solid with grout. Behind the wall we place gravel backfill, a perforated drain pipe, and weep holes so water never builds pressure against the back. On a real slope the footing carries serious load, so the design has to match the soil and the height.
That is one of the best things you can do with a hillside lot. A yard that falls away toward Mulholland is hard to use as one long slope. By building a series of retaining walls at different heights, we cut the grade into flat terraces, level pads you can actually stand on, plant, or furnish. One terrace might hold a patio, another a lawn or a garden. Each wall holds the soil above it and drains the water behind it. The result turns a steep, wasted slope into usable outdoor rooms that step down the hill in stages.
Drainage is what keeps a retaining wall standing, so we build it into the wall from the start. Wet soil is heavy, and if water collects behind a wall it pushes with enormous force. To relieve that, we backfill the space behind the wall with clean gravel rather than dirt, then run a perforated drain pipe along the base so collected water has somewhere to go. Weep holes through the face let any remaining water escape to the front. On the Tarzana hillsides south of the boulevard, where runoff moves downhill fast, this drainage layer matters as much as the steel and grout.
Yes, and north of Ventura Boulevard that flat tract work is the bread and butter. A driveway, a front walkway, a patio slab, or a pool deck all follow the same fundamentals. We grade and compact the subgrade, set a base, place reinforcement on chairs so the steel sits inside the slab, then pour concrete at the right thickness for the use. A pool deck gets a slip resistant finish and a slope that carries water away from the coping. A driveway gets a thicker slab because it carries vehicles. Get the base and the reinforcement right, and the surface lasts for decades.
Most of the work on a good slab happens before any concrete arrives. We start by stripping soft or organic soil and grading the subgrade so it drains. Then we compact it, because loose ground settles and settling cracks concrete. On top of that goes a base course of crushed rock, also compacted. Reinforcement comes next, either rebar or welded wire mesh, held up on chairs so the steel ends up in the middle of the slab where it does its job. Only then do we pour, at a thickness matched to the load. Skip any of these steps and the slab fails early.
Concrete cracks because it shrinks as it cures and moves as the ground and temperature change. That is the nature of the material, so the goal is not to prevent cracks entirely but to control where they happen. We cut or tool control joints into the slab at planned spacing, which creates weak lines where the concrete is meant to crack out of sight and in a straight line. Proper curing, keeping the slab damp as it gains strength, reduces the shrinkage that drives early cracking. Correct thickness, a compacted base, and reinforcement all work together to keep any cracks tight and cosmetic rather than structural.
There is a wide range, and the finish sets the whole look. A broom finish is the classic, a light texture swept across the surface for traction and a clean, simple appearance. Exposed aggregate washes away the top layer to reveal the stone inside for a natural, pebbled surface. Stamped concrete presses patterns into the wet slab to mimic stone, brick, or plank. Integral color mixes pigment through the whole batch, while stains add color to a cured slab. A sealer protects any of these and can deepen the color. We help you match the finish to the house and to how the surface will be used.
Yes, all three, and they often tie together on the same property. Walkways connect the drive, the door, and the yard, poured or set at a comfortable width and slope. Steps handle the change in grade between levels, built with consistent rise and run so they feel safe underfoot. View terraces are a favorite on the south side of Tarzana, where a flat pad held by a retaining wall gives you a place to sit and take in the hills toward Mulholland. We lay all of it out together so the paths, the steps, and the terraces flow as one connected design.
Yes. Concrete block walls are a core part of masonry work, used for property walls, garden walls, planter walls, and low seat walls around a patio. A block wall is not just stacked units. We pour a footing, set vertical rebar, lay the block, and grout the reinforced cells solid so the wall acts as one strong unit. Horizontal steel ties the courses together. Once the structure is sound, we can leave the block clean, stucco it, or face it with stone or brick veneer. Seat walls and pilasters at an entry or a driveway are built the same careful way.
Absolutely. Veneer is the finish layer that gives a wall its character. Natural stone, manufactured stone, or brick is set with mortar over a solid, properly built structure, whether that is a new block wall or the face of a retaining wall. The wall behind does the structural work, and the veneer carries the look. Manufactured stone offers a lighter, more consistent option, while natural stone brings depth and variation. On the view lots south of the boulevard, a refined stone veneer on a terrace wall reads as a real, permanent part of the home rather than an add on.
The difference is how the surface is held together. Hardscaping with pavers is a dry laid system, units set on a bed of sand and compacted gravel with no mortar, so the pieces can flex and can be lifted individually. Concrete and masonry is bonded work. A poured slab is one continuous piece of concrete, and a masonry wall is block or brick locked together with mortar and grout. Both have their place. Pavers suit a patio you might want to adjust later, while poured concrete and mortared walls give you a single, monolithic structure. We build both and help you choose.
On a steep lot the footing is the part you never see and the part that matters most. A retaining wall on a hillside is holding back tons of soil, and all of that load runs down through the wall into its footing and the ground below. So the footing has to be wide enough and deep enough to spread that load without settling or sliding. On the slopes south of Ventura Boulevard, the footing size, the depth below grade, and the rebar all follow the height of the wall and the soil it sits in. This is why a real hillside wall is engineered rather than guessed.
Often, yes, and it depends on the specifics. Retaining walls above a certain height, or walls that carry a surcharge such as a slope or a structure above them, need engineering and a building permit. Given the grades south of Ventura Boulevard, many hillside walls in Tarzana fall into that category. Driveways can involve a permit too, especially the apron where the drive meets the street, because that portion sits in the public right of way. We walk you through what your project requires and handle the process so the work is done correctly and to code. We do not cut corners on permits.
On a view lot, the finishes should sit quietly and let the view lead. Many south side homes in Tarzana want a refined look, so we lean toward materials that feel natural and permanent. A terrace might get an exposed aggregate or a subtle stamped finish underfoot, with the retaining wall faced in a warm stone veneer that ties to the hillside. Integral color keeps concrete soft rather than stark white, and the right sealer holds that tone. We coordinate the flatwork, the wall veneer, and the planting so the terrace frames the view toward Mulholland instead of competing with it.
Concrete sets quickly but gains strength over time, so there is a difference between walking on it and loading it. As a general guide, you can usually walk on a new slab after a day or two. Wait about a week before rolling anything heavy across it, and give a driveway a good deal longer, commonly around a month, before parking vehicles on it. Those windows let the concrete cure and build the strength it needs. We keep the slab damp during the early curing period, because slow, moist curing is what produces a hard, durable surface. We will give you clear timelines for your specific pour.
Every part of your project is built by one licensed contractor. One licensed contractor stays accountable for the work. The same people who dig the footing, tie the steel, set the block, and finish the concrete are Daniels Landscaping employees, from the first day on site to the last. That is how we hold a consistent standard across the flatwork and the masonry, keep the schedule in our own hands, and stand behind the result. When you hire us, you get our crew, not a rotating cast of outside hands. It also means one point of accountability for the whole job.
Getting started is simple. Call us at (818) 443-9300 and we will set up a time to come out, look at your lot, and talk through what you want to build, whether that is a driveway on the flats or a terraced hillside south of the boulevard. We look at the grade, the soil, the drainage, and the finishes, then put together a free written estimate that lays out the scope and the cost in plain terms.
