Lakewood Footings & Piers

The truck is the least interesting thing that happens all morning. The holes are the job.

The truck is the least interesting part of a footing pour. It arrives, it turns, it discharges, and when the morning went right that's forty boring minutes. What decides whether your deck, porch, detached garage, or shop still sits level in fifteen years happened before the chute ever swung out, down in holes nobody will look at again.

We drill and pour bearing all over Lakewood, and the ground hands us a different morning depending on which part of town we're standing in. Applewood gives us one thing, the rise toward Green Mountain gives us another, and the low ground around Bear Creek gives us water. Here's how the day actually runs, hole by hole, including everything that can stop it.

First light, and an argument with the bottom of every hole

Layout goes down the afternoon before, so the morning starts with drilling. Then the part crews earn their money on: cleaning. Every hole gets the loose spoil pulled out of the bottom, because a pier bearing on four inches of its own cuttings is a pier bearing on nothing. Standing water gets pumped. Sidewalls get checked for sloughing. Depth gets measured against two requirements people constantly confuse.

Frost sets a minimum depth. Load sets the width, or in a drilled pier, the diameter and the side friction the shaft develops. Different questions, different answers, and satisfying one doesn't satisfy the other. A wide, shallow pad under a porch post carries the weight beautifully and still gets shoved upward by soil freezing underneath it. Our engineer sizes both. The crew's job is confirming the hole matches what got drawn.

What we find at the bottom of a hole, and what it does to the morning

Every one of these has stopped a pour for us. None of them is a reason to keep going anyway.
What's in the holeWhy it stops the pourWhat happens next
Water standing in the bottomConcrete placed into water washes cement out of the mixPump it, let it recover, and re-check before anything goes in
Soft, spongy material underfootThe bearing number on the plan assumed firm groundDig deeper to something solid, or the engineer resizes it
A sidewall crumbling into the shaftLoose soil falling in ends up under the concreteCase the hole, or open it up and step back to stable material

A frozen crust in the top of the excavationFrozen ground thaws later and leaves the footing hangingStrip the frozen material out before a single yard is placed
Old buried concrete or a big rootNeither one is bearing material and both hide voidsBreak it out, chase it to clean soil, then reassess depth

Steel, cover, and the ten minutes before the chute swings

Cages get tied on the ground and dropped in, then held so they sit centered instead of leaning against dirt. That gap matters more than most people expect. Steel needs concrete completely around it, so it stays dry and does its job for the life of the structure. Bar pressed against a soil wall is bar with a rust clock running on it.

Then the small things that are miserable to fix later. Dowels for whatever ties in above. Sleeves for conduit somebody will want next year. Anchor hardware set to the layout rather than eyeballed while the concrete stiffens. Elevation marks so the tops come out at one height across a row of piers, because posts cut to different lengths read crooked from the yard forever.

Deck, porch, shop, barn, or an addition that needs bearing under it?

We'll walk the site, tell you how deep we expect to go, and put it in writing before anybody rents a machine. (303) 569-4046.

Digging weather in this town, month by month

Late spring through fall is the easy stretch, and even then the afternoon is a factor. A storm that fills six open holes turns a clean morning into a pumping exercise, so we drill and pour the same day whenever we can. Open holes collect water, collapse edges, and become a hazard around a house with kids and dogs in it.

Winter work happens, it just costs attention. Frost in the upper ground is slow to auger and has to come out entirely, warm mix water and blankets protect the concrete while it sets, and nobody places on frozen bearing. Rock is its own season on the west side of town, indifferent to the calendar. If you want a deck usable by Memorial Day, get the holes in during a February or March window and let the concrete take its time while your builder orders material.

Because a hole starts going bad the moment it's open. Sidewalls dry and crumble, soil at the bottom relaxes, and one rainstorm turns solid bearing into slop that has to be cleaned back out. Same-day placement means the material we inspected is the material the concrete lands on. When a schedule forces a gap, we cover the holes and re-inspect every one before we pour.

Cover is the layer of concrete between reinforcing steel and the outside world. It keeps moisture and soil chemistry away from the bar, which is the only thing stopping it from rusting, swelling, and cracking the concrete apart from the inside. Roughly three inches against earth is what we aim for. A cage leaning on a dirt wall has zero cover right where it matters.

For footings and piers, much less than for flatwork. There's no finished surface to ruin, and the top of a footing gets buried anyway. What we watch is water sheeting into the excavation and washing along the fresh edge before it sets, or filling a form and floating the anchor hardware out of position. We tent tops and check hardware once the weather clears.

Almost always a void in the sidewall or a soft pocket that opened up as concrete pushed against it. Sandy fill and old backfill do it regularly. It isn't a defect, it's the ground telling you it had a gap. We note where it happened, because a hole that ate an extra half yard is worth mentioning to the engineer before we load the structure above it.

On permitted work, an inspector looks at open holes and steel before any concrete is placed, and our own crew lead walks every hole first so nothing gets flagged that we could have caught. Standing water, frozen material, a bottom that isn't clean, or a cage without cover will all stop the pour. So will a rock ledge under half a footing.

Usually that's good news, but it depends on what kind of rock. Competent bedrock is excellent bearing and we may not need to go deeper. Loose weathered rubble looks like rock and isn't. The other question is whether every support on that structure can reach the same material, because half the footings on rock and half on soil is worse than all of them on soil.

Framing crews commonly start within a few days on residential work, and heavier loads wait longer. Concrete keeps gaining strength for weeks, reaching design strength at about 28 days. What matters more than the calendar is what's going on top. A deck frame is one thing. Setting steel or masonry on green concrete is a conversation with the engineer first.
