Centennial RV and Trailer Pads

Homeowners picture pour day as the whole job. It is the loud part, and it is the part the neighbors watch. But by the time the first truck backs down the side yard, the outcome is already mostly determined, because a pad that holds a loaded rig for twenty years is decided by grade stakes and a plate compactor, not by how fast the finishers move.

We build these across Centennial wherever a lot has room. Piney Creek and Foxridge have side yards deep enough to swing a trailer into, and Walnut Hills properties often have the width to run a pad alongside the existing drive. What follows is what actually happens on your property, day by day, so nothing on the schedule catches you sideways.

The two days before any concrete arrives

Day one is layout and dirt. We stake the footprint off the real dimensions of your rig plus room to open the door and walk around the tongue, then strip the topsoil and haul it off. Topsoil is organic, organic material compresses, and no slab survives being built on it. Then we cut to grade, which on a pad like this means going deeper than people expect, since we are stacking six inches of concrete over a base section that has to carry axle loads without dishing.

Day two is base, forms, and steel. Aggregate goes down in lifts with compaction between each one. Forms get set to a pitch, never dead level, so water leaves instead of sitting where the tires do. Then the steel: number four rebar tied on a grid, sitting on chairs so it ends up in the middle third of the slab rather than lying on the dirt doing nothing. That is what a suspiciously low bid leaves out. Steel on the ground is decoration.

Pour morning, in the order it happens

• Access route protected with plywood where a truck crosses lawn or an existing drive
• First truck discharges at the far end, so we work toward the exit and never strand ourselves
• Concrete placed, raked to depth, and screeded flat between the forms
• Bull float pass while the surface is open, then a wait, since floating early traps water in the top layer
• Edges tooled and the apron transition brought level with the existing drive
• Broom finish drawn across the direction of travel for tire grip
• Control joints saw cut the same day, before the slab picks its own crack lines
• Curing compound on, forms left in place, site cleaned before the crew leaves

Weather runs the clock on a pour this size

A pad big enough for a motorhome is a lot of open surface, and open surface is where our weather does its damage. In July the sun at this altitude plus a dry wind pulls moisture out of the top faster than the slab can bleed it back, and you get a crusted skin over soft concrete. So summer pours start at first light and we keep an evaporation retarder and hoses close.

Afternoon storms are the other half. Rain on concrete that has finished and begun to set is a nuisance we cover with plastic. Rain during finishing is destructive, since it works water into the paste and leaves a surface that dusts and flakes from then on. When the forecast turns ugly we start early, keep sheeting on hand, and push the date if the morning radar is bad enough. You want us making that call.

Cold changes the recipe rather than the plan. We warm the water at the plant, run an accelerator with no chloride in it, and blanket the slab until it has strength. Frozen subgrade is the hard stop, every time.

Four places the pad can go

The pours that go sideways are the ones where nobody walked the route first. We show up with concrete on the way and find a gate two inches narrower than the buggy.What the crew sees on site
