Local Asphalt Paving in Excelsior Springs, MO
On this topography, drainage is plumbing — inlets, leads, and outfalls. Crowning the middle of a lot achieves nothing.
Tarmasters paves commercial lots and driveways across Excelsior Springs, Missouri. The city sits on hills over Haig-Wabash series silty clay, so lots need collected, piped drainage rather than a crown — and an overexcavated granular base beneath. Insured, bonded, working the metro since 2014.
In flat towns, a parking lot's drainage is a shape: you crown the middle and the water finds the edges. Excelsior Springs does not work that way. The ground here is hills and creek corridors, and a commercial lot on it is a small piece of a much larger water system — receiving flow from above and having to deliver it somewhere specific below.
That makes drainage here closer to plumbing than to grading. Inlets in the right places, at the right level. Leads that are actually clear. An outfall that can take what the hill sends it. A lot can be perfectly graded and still fail because a lead pipe silted up three winters ago and nobody opened a lid to look.
We work the whole city from Lee's Summit — the Historic Downtown District, the retail and medical corridors along MO-69, and residential drives across the older streets. Insured and bonded, and clear about whether your surface needs repair, resurfacing, or a drainage correction before either is worth doing.
What Tarmasters does in Excelsior Springs
Commercial paving, repair, and driveways have dedicated pages for this city. Open the others for detail.
Commercial Asphalt Paving
Retail, hospitality, and medical lots built with the collection system designed first and the surface laid to serve it.
Go to Commercial Asphalt Paving →Asphalt Repair
Full-depth repair where run-off has been taking base material out along the same line for years.
Go to Asphalt Repair →Driveway Paving
Sloped drives on the older streets, where where the water goes matters more than how thick the mat is.
Go to Driveway Paving →Overlays & Resurfacing
A new wearing course on the 1970s–90s retail sprawl that is at the end of its original surface life.
Go to Overlays & Resurfacing →Crack Sealing
With about 42 freeze-thaw cycles a year here, closing cracks before winter is the highest-value job on the list.
Go to Crack Sealing →Sealcoating
Surface protection on sound pavement — worth doing once the drainage is actually working.
Go to Sealcoating →Line Striping
Layout and accessible routes, which on this topography usually need a grade check first.
Go to Line Striping →Asphalt Milling
Cutting a surface back so a corrected fall can be built in without raising the lot past its kerbs.
Go to Asphalt Milling →The parts of a lot's drainage, and how each one fails
Six components between the rain landing on your lot and the water leaving your property. If a quote for a sloped site here does not mention several of them, it is pricing asphalt rather than solving the problem.
| Component | What it does | How it fails | What that costs you |
|---|---|---|---|
| Cross-slope and crown | Moves water off the surface to somewhere it can be collected | Built flat, or crowned into a wall on a sloped site — the water has nowhere to go | Ponding, stripping, and a saturated base |
| Valley gutter | Carries collected water across a lot without a kerb interrupting the drive path | Silts up, or is laid too flat to keep water moving along it | A permanently wet strip through the middle of the lot |
| Kerb and gutter | Contains the flow at the edge and delivers it to an inlet | Cracked or settled sections let water behind the kerb and under the pavement | Edge failure — the most expensive part of a lot to rebuild |
| Catch basin or area drain | Takes surface water into the piped system | Set too high, or the ring around it settles so water runs past rather than in | The lot drains to a point that no longer accepts water |
| Lead pipe | Carries water from the basin to wherever it is going | Blocked with silt and debris; nobody inspects it until a lot floods | The whole system stops working while looking entirely fine from the surface |
| The outfall | Discharges into the storm system or a creek corridor | Erodes at the discharge point, or is undersized for the flow the hill delivers | Damage downstream, and sometimes a problem that is no longer yours alone |
Flood risk in this city is moderate along the creek corridors that run through the centre, so where a lot discharges matters beyond the property line. That is worth checking with the city before a system is altered.
Why the base matters in Excelsior Springs
- —
The clay moves twice a year
Clay County's plastic clay shrinks in summer drought and swells with fall rains, generating vertical movement that cracks pavement from below. Every Excelsior Springs project requires overexcavation and a minimum 8" granular base to isolate the wearing surface from subgrade movement.
- —
The winter is harder here than south of the river
Clay County logs 42 freeze-thaw cycles annually. Combined with the moisture retention of the local clay, this cycling is the primary driver of pothole formation and crack propagation on every commercial surface in the city.
- —
The traffic concentrates at the turns
Regional traffic on MO-69 plus resort and healthcare visitors mean heavy turning and braking in the retail corridor. Entrances and turning points wear long before the parking does, so we build them heavier.
- —
Two very different ages of pavement
The downtown core has assets from the early twentieth century, with sloping ground that makes accessible routes genuinely difficult. The peripheral retail from the 1970s to 90s is at the end of its original surface life. Those are different budgets and different conversations.

Working in Excelsior Springs
Tarmasters is a Kansas City–owned paving contractor and the asphalt division of Ford Concrete and Paving, working the metro since 2014. The concrete side is directly relevant here: kerb, gutter, valley gutters, and basin surrounds are concrete work, and on a hillside lot they are not accessories — they are the drainage system.
Work runs under City of Excelsior Springs building codes. On the historic properties the constraints are fixed grades and accessible routes; on the corridors they are stormwater and access. Insured and bonded — measured estimate, fixed price, firm sequence, and a straight answer about what your surface needs.
Excelsior Springs paving questions
Why is crowning the lot not enough here?
Because a crown only moves water a few metres. Unlike flat-terrain cities to the south, Excelsior Springs' commercial lots are built on grades that funnel stormwater toward buildings and lot low points. Positive drainage design here means precision grading, curb placement, and catch basin integration — not just crowning the lot center. On a hillside property the water arriving from above is at least as much of a problem as the rain landing on your own surface, and it has to be intercepted, carried, and discharged. That is a system, not a slope.
How do we know if our catch basin is actually working?
Watch it in a real storm rather than guessing. Water running past a basin instead of into it usually means the casting is sitting high relative to the surface around it, or the ring of pavement at its edge has settled and formed a lip. Both are fixable and neither is expensive — but a basin that has silted up in its lead pipe will look perfect and still do nothing.
How aggressive is Haig-Wabash series silty clay under a lot here?
Aggressive enough that we overexcavate. Clay County plastic clay shrinks in summer drought and swells with autumn rain, and that vertical movement cracks pavement from below. Every project here wants a minimum eight-inch granular base to isolate the wearing surface from what the ground is doing beneath it.
Is the downtown different from the retail corridors?
Very. The historic core has pavement and walkways going back to the early twentieth century, with sloping topography that makes accessible routes genuinely difficult and concrete that has taken decades of de-icing. The peripheral retail along the highways is 1970s to 90s and is at the end of its original surface life — a straightforward, if large, resurfacing question.
Do you work around the hotel and hospital properties?
Yes, phased. Those properties cannot close, so the lot is divided into sections and the sequence runs one section at a time with access routes held open. The paving stage needs its section completely clear for about a day, and we schedule that against your calendar before anything is booked.
