Concrete & Stamped Concrete in Clark County, WA

All concrete cracks — it shrinks as it cures. The job of a good installer is to control where it happens by placing joints correctly so the cracks land in the tooled lines instead of across the open field. Base preparation is the other half; slabs on soft or uncompacted ground crack regardless of joints.

Foot traffic after about 24 to 48 hours depending on weather. Furniture after a week. Keep vehicles off a new driveway slab for a month. Concrete keeps gaining strength for weeks after it looks finished.

Roughly every two to three years in our climate. Our wet winters and summer UV are both hard on sealer, and a maintained seal is what keeps the color from washing out.

A compacted aggregate base over prepared subgrade, and on soft or poorly draining ground a geotextile separation layer as well. Concrete is strong in compression and weak in tension, so it does not bridge soft spots — it cracks over them. Almost every badly cracked slab we are asked to replace failed underneath, not in the mix.

They are tooled or sawn lines that deliberately weaken the slab in a straight line so the inevitable shrinkage crack happens there instead of wandering across the middle. Spacing and depth are what make them work. A slab with joints placed too far apart or cut too shallow will crack wherever it likes.

A compressible separation where the new slab meets the house, an existing patio, a step or a post. It lets the two move independently, because they will. Pour a patio hard against a foundation with no isolation and the slab either cracks along that edge or transmits movement into something you care about more.

Reinforcement does not stop concrete cracking — it holds the crack tight and stops the two sides going their separate ways. Whether a residential slab needs mesh, rebar or fibre depends on thickness, loading and what is underneath. It is not a substitute for a properly compacted base, and it is often sold as though it were.

Rain is manageable with planning; a hard freeze during the first days of curing is not, because concrete that freezes before it gains strength is permanently weakened. We will pour through most of the wet season and stand down for a cold snap. If a pour needs to move, we tell you rather than gamble with your slab.

It is walkable in a day or so and takes vehicle traffic considerably later, but full strength develops over roughly a month. Curing is a chemical reaction, not drying out, which is why keeping a fresh slab from losing moisture too fast matters more than most people expect.

Fresh concrete impressed with a texture and colour to imitate stone, slate or timber. It looks good and it is a continuous surface, but it is still one rigid slab, and the colour is a surface treatment that wears in traffic and fades in sun. In our climate it also needs resealing on a cycle to keep looking right.

It can be, particularly once it has been sealed, and that is worth thinking about seriously on anything with a slope or near a step. A grit additive in the sealer helps considerably. On a shaded, north-facing surface that stays damp for seven months, texture matters more than pattern.

Patching concrete is honest work but it will always show. Concrete cures to a colour that depends on the mix, the weather that week and years of weathering, so a new patch beside an old slab is visible. Where appearance matters, replacing a whole bay between joints usually looks far better than a repair.

An overlay is possible on a sound slab, but if the existing concrete is cracked or moving, the new surface will crack in the same places within a couple of years — it simply telegraphs through. Where the old slab has failed because of what is under it, the fix is removal and a proper base.

Concrete gives a smooth continuous surface and takes vehicle loads well; pavers flex with seasonal ground movement, can be lifted for utility access and are repairable unit by unit. On ground that moves through our wet and dry cycle, pavers are more forgiving. On a stable, well-drained site, either works.

It depends entirely on use — a patio that carries people is a different specification from a driveway carrying vehicles or an RV. Thickness, base depth and reinforcement get decided together, not separately. We size it for what will actually be on it, including the vehicle you have not bought yet if you tell us about it.

Yes — a definite, consistent fall away from the house, enough to shed water without being noticeable underfoot. A dead-flat slab holds water in every slight hollow, and in a climate this wet that means algae, staining and a slick surface all winter.

Preparation is most of the calendar and the pour is often a single morning. Demolition and removal of an old slab, excavation, base and forming typically run several days, then the pour, then curing time before you can use it. The finishing window on pour day is short and weather-dependent, which is why we do not stack two pours in a day.

Efflorescence — soluble salts carried to the surface as moisture moves out of the slab, then left behind when it evaporates. It is cosmetic, extremely common in wet climates, and usually weathers off over the first year or two. It is a sign of moisture movement, not of a bad pour.
