Absolute Precision
Asphalt Paving
From full-depth tear-outs to high-density overlays. We build unbreakable roads, parking lots, and municipal infrastructure designed to withstand extreme Texas heat and heavy industrial traffic.
Paving Capabilities
Our San Antonio paving division operates with military precision. We deploy company-owned machinery and elite crews to execute heavy infrastructure projects without compromise.
Full Sub-Base Tear-Outs
We don't pave over failure. If your subgrade is compromised by extreme San Antonio soil shifting, our heavy machinery crews completely excavate the site. We treat the raw earth before laying a single ton of rock.
High-Density Overlays
For existing infrastructure with a sound base but surface-level oxidation, we provide precision milling and high-density hot mix overlays. Engineered to extend the lifespan of commercial parking lots and municipal roads.
New Road Construction
From undeveloped dirt to striped, finished asphalt. We handle the entire lifecycle: clearing, grading, base stabilization with Permabase, and top-tier hot mix application.
Structural Pothole Repair
Temporary patches fail. We saw-cut the perimeter, remove the damaged asphalt and base, treat the cavity with PHPM-50, and install a structural hot-mix patch that outlasts the surrounding pavement.
The Crownwood Protocol
Excellence is not an accident. It is the result of strict adherence to our rigorous, internally developed paving methodology designed specifically to defeat South Texas soil and climate conditions.
Site Preparation & Excavation
We analyze the subgrade composition and determine the required excavation depth. Using heavy machinery, we remove failing asphalt, organic topsoil, and moisture-compromised base material down to solid, undisturbed earth.
Subgrade Stabilization (Permabase)
San Antonio's expansive clay soils destroy untreated pavement. We inject our proprietary Permabase chemical stabilizer deep into the subgrade, fundamentally altering the soil's molecular structure to prevent swelling, shrinking, and extreme moisture absorption.
Base Rock Installation & Grading
We import and install TxDOT Type A, Grade 1 or 2 crushed limestone base. Using laser-guided grading GPS technology, we establish perfect pitch and slope to ensure 100% positive water drainage away from the structure.
Hot Mix Application & Compaction
High-density hot mix asphalt, specifically engineered for extreme Texas thermal loads, is laid via tracked pavers. Vibratory steel-wheel and pneumatic tire rollers compact the mat to terminal density, achieving an impenetrable, monolithic surface.
Comprehensive Asphalt Solutions
Crownwood Chemicals offers a full spectrum of asphalt paving services designed for the unique geological and climatic challenges of South Texas. From massive commercial tear-outs to precision milling, our in-house crews execute with zero compromise.
Commercial Parking Lot Paving
Crownwood Chemicals engineers high-volume commercial parking lots designed to withstand continuous heavy industrial traffic and extreme San Antonio heat. We handle everything from subgrade stabilization using our proprietary Permabase technology to the final layer of high-density TxDOT specification hot mix asphalt. A failing parking lot is a liability; we construct assets that last decades.
Asphalt Milling & Resurfacing
When the base is solid but the surface has oxidized and cracked due to intense UV exposure and thermal expansion, a full tear-out isn't always necessary. Our precision milling equipment removes the damaged top layer, allowing us to install a high-strength asphalt overlay. This restores structural integrity, drainage, and aesthetic appeal at a fraction of the cost of total reconstruction.
Structural Pothole Repair & Crack Sealing
Water intrusion is the number one cause of asphalt failure in Texas. We don't perform temporary 'throw-and-go' patches. Our structural repair protocol involves saw-cutting the perimeter, removing the compromised asphalt and wet base material, treating the cavity with PHPM-50 for absolute zero moisture permeability, and installing a dense-graded hot mix patch. We then hot-pour rubberized crack sealant to prevent future water ingress.
New Road & Driveway Installation
From private ranches to complex municipal roadways, our new asphalt installation services guarantee a flawless finish and an unbreakable foundation. We manage the entire lifecycle: land clearing, precision grading, base rock installation, and final asphalt placement. Our use of laser-guided GPS equipment ensures perfect slopes for optimal water runoff.
Paving Questions
01.How long does commercial asphalt last in San Antonio?
A properly engineered commercial parking lot in San Antonio should last 15 to 20 years. However, survival depends entirely on the subgrade. Because South Texas soil has high clay content that swells when wet and shrinks during droughts, stabilization is mandatory. Without our Permabase treatment, untreated lots often fail within 3-5 years due to base shifting.
02.Do I need a complete tear-out, or can you just do an overlay?
We never pave over failure. If your existing asphalt exhibits deep 'alligator' cracking or severe rutting, the base underneath is compromised, requiring a full-depth tear-out and stabilization. If the surface is simply oxidized (graying) with minor surface cracks, a precision milling and high-density overlay will restore the pavement.
03.How soon can we drive on a new asphalt installation?
We recommend keeping heavy traffic off new hot mix asphalt for at least 24 to 48 hours to allow the oils to cure and the surface to stiffen. Standard vehicle traffic is generally acceptable within 24 hours, but heavy 18-wheeler traffic should be diverted if possible for the first few days, especially during extreme summer heat.
04.Why should we choose Crownwood Chemicals for paving?
We are an engineering-first construction firm. Most paving companies focus only on the surface layer. We manufacture the chemical soil stabilizers (Permabase, PHPM-50) that secure the foundation. By combining our proprietary materials with an elite, in-house heavy machinery crew, we build infrastructure that outright defies Texas weather.
Notice on Substandard Paving
Many San Antonio contractors offer "cheap" overlays on failing subgrades. This is a predatory practice that guarantees structural collapse within 24 months. Crownwood Chemicals requires a site engineering assessment prior to any top-coat application. We build assets, not liabilities.
Serving San Antonio & Bexar County
Our equipment yard and chemical manufacturing facilities are strategically located to dispatch elite paving crews rapidly across the San Antonio metropolitan area. We understand the specific geotechnical demands of building on Edwards Plateau limestone and the surrounding expansive clay belts.
