Lakewood Retaining Wall Contractors

Take the whole grade change in one bite, or split it into two. That choice drives everything else about the job.

Every wall conversation starts with one number: how much elevation you're holding back. Everything after that is arithmetic and honesty. Take six feet of grade in a single wall and you have a real structure, with a wide footing, serious steel, and drainage that has to work the first time. Take the same six feet in two shorter steps and you have two simpler walls plus a planted bench between them, along with a different set of headaches.

Neither answer wins automatically. On the sloped side of town, out toward Green Mountain and through Solterra, we build both, occasionally on one property. What we won't do is pick before we know what sits above the wall, what sits below it, and where water shows up during a hard storm.

One bite or two, and why the math isn't linear

Soil pressure doesn't grow evenly with height. Double the retained height and the force trying to tip a wall over climbs far more than double, which is why a three-foot wall is a weekend and a seven-foot wall is a structure with an engineer's name on it. Footings get wider. Steel gets heavier. The consequences of a plugged drain get much less forgiving.

Terracing splits that problem into two smaller ones, and it can be the cheaper, calmer answer. But only if the walls sit far enough apart to act independently. Put the upper wall too close and its weight, plus the soil it holds, presses down on the ground right behind the lower one. Now you've built a single tall wall with a decorative gap in the middle, and the bottom half is carrying a load nobody designed it for. Real terracing needs horizontal room. If the yard can't give that up, the honest answer is one engineered wall.

One tall wall against a terraced pair

Same grade change, two ways to take it. Here's the honest trade.
ConsiderationSingle tall wallTwo shorter terraces
EngineeringNeeded, and the design gets specific to your soilOften lighter, as long as the walls are genuinely separated
FootprintCompact. The wall takes a narrow strip of yardWide. You give up horizontal room to gain the split
ExcavationDeeper and taller, with more shoring during the buildShallower cuts, easier machine access on a slope
DrainageOne system that has to be right, no second chancesTwo systems, and the upper must not dump on the lower
What you get to useFlat ground above and below, nothing in betweenA usable planted bench between the two levels
Failure behaviorBigger consequences, slower warning signsTrouble shows in the lower wall first, and earlier

The point where a wall stops being landscaping

Short garden walls holding a foot of soil are edging. They can lean, and the worst outcome is a Saturday spent rebuilding them. Somewhere above that, a wall turns into a structure people stand on top of, park behind, and build near, and failure stops being cosmetic. That's the wall we want an engineer designing, with a footing sized to the soil under it and steel sized to the pressure behind it.

Lakewood adds a wrinkle worth knowing. Along the foothill edges a wall can sometimes be founded on rock, which is excellent for bearing and complicates drainage, since water traveling on top of that rock has to be caught and routed somewhere. Down in the flats near Belmar and Bear Creek it reverses: bearing takes more thought, water is easier to move, and frost depth drives the bottom of the footing. Same wall height, two different designs.

What we measure before recommending either one

  • Total grade change, top of slope to bottom, not the height you pictured
  • What lives above the wall now and what might live there in five years
  • Distance to the property line and to anything nearby with a footing
  • Where uphill water arrives during a real storm, not where the plan says
  • What the soil is, and whether rock shows up at a useful depth
  • How equipment reaches the work, since access moves price more than height
Got a slope you can't use and no idea which way to solve it?

We'll walk it, take the grade, and tell you straight whether it's one wall, two, or a regrade you don't need us for. (303) 569-4046.

The season that suits wall work, and the one that fights it

Late spring through fall is the working window, with a caveat. A hillside that just absorbed a month of snowmelt won't hold a clean excavation face, so early spring digs run slower and riskier than the calendar suggests. Give the ground a few dry weeks and the same cut behaves itself.

Fall is our favorite for walls. Cool weather treats curing concrete well, soil is usually at a moisture content that compacts, and there's time to place backfill and finish grade before the ground stiffens. Winter footings go in with warm mix water, accelerators, and blankets, and we won't place on frozen bearing. The step we refuse to rush in any month is the gravel and the drain behind the wall. That's what holds your wall up, and nobody goes back for it later.

Total grade change, from the top of the slope to where the ground levels out below. Homeowners usually describe the wall they pictured, which tends to be shorter than what the yard actually needs. Once we have the real number, we look at how much horizontal room is available. Those two figures together decide whether terracing is even on the table.

Far enough that the upper wall isn't loading the ground behind the lower one. There's no single number, since it depends on the heights and the soil, and it's the sort of thing an engineer calculates rather than a contractor eyeballs. Rough guide: if the bench between them is too narrow to walk and plant comfortably, it's too narrow structurally.

Either the backfill is still consolidating, or water is carrying fines out through the drainage and leaving voids behind. A dip along the top of a wall is worth chasing now. It means water is moving back there in a way nobody planned, and the process taking away that soil will eventually take away the support the wall is counting on.

It still gets a footing, but founding on competent rock shifts things in your favor: bearing stops being the limit and frost depth matters less. What gets harder is water. Rock doesn't absorb any, so everything arriving from uphill runs along the surface of it and straight to the back of your wall. Drainage has to be built for that.

Sometimes, and it's closer than people expect. You save on steel, footing width, and the engineering a tall wall demands. You spend more on length, because two walls mean two footings, two drain systems, and two rounds of gravel backfill. Terracing wins most clearly when the single-wall version would have crossed into heavily engineered territory.

Plant it, yes, and that's half the reason to terrace. Irrigate it carefully. Every gallon you put on that bench goes into the soil directly behind the lower wall, the exact place you paid to keep dry. Drip lines set back from the edge, no spray heads aimed downhill, and a bench graded to shed water rather than pond it.

It's a fair question on steeper ground, and it's a different failure than a wall tipping over. A slope can slide beneath and around a perfectly built wall when the failure surface runs deeper than the footing. That's a geotechnical evaluation rather than a guess, and on tall walls cut into significant slope we want that answer before anybody prices concrete.
