FAQs

Water is the primary cause of damage to asphalt surfaces. Areas with persistent standing water can lead to the deterioration of both the asphalt and its underlying base. Over time, water exposure weakens the asphalt mixture, reducing its overall strength and durability.

While the terms are often used interchangeably, "asphalt" and "blacktop" refer to the same basic material: a mixture of crushed stone and bitumen, which is a petroleum-based binding agent. Blacktop is typically considered a specific type of asphalt, often used for driveways and smaller projects. The term "asphalt" can encompass a wider range of mixtures and is commonly used in reference to larger-scale applications such as roads.

Excessive water exposure is detrimental to asphalt driveways and sidewalks. Water can infiltrate the surface, eroding the gravel and sand base. This process can lead to warping and distortion of the upper asphalt layers, resulting in crack formation. To prevent this issue, it's crucial to ensure proper drainage and avoid water pooling on asphalt surfaces.

The typical lifespan of asphalt surfaces ranges from 15 to 25 years, depending on various factors such as usage, maintenance, and environmental conditions.

The cost of sealcoating varies based on factors such as driveway size and the type of sealant chosen. Asphalt sealcoating products generally range from $0.06 to $0.38 per square foot. The total project cost can be as low as $150 for smaller areas, while larger projects may reach up to $2,000.

The durability of sealcoating depends on several factors, including climate conditions, traffic volume, and the quality of application. When properly applied, a sealcoat typically lasts between 2 to 5 years before requiring reapplication.

Sealcoating is generally considered a cost-effective preventative maintenance measure for asphalt surfaces. It significantly extends the lifespan of driveways and parking lots, provides protection against damage, and enhances aesthetic appeal. The expense of sealcoating is considerably less than the cost of repairing or replacing damaged asphalt.

The cost of installing a 40x60 concrete slab (4 inches thick) for buildings typically ranges from $9,600 to $19,200. The price per square foot for a 4-inch slab usually falls between $4 and $8, including materials and labor, with variations based on location.

The appropriate thickness of a concrete slab is determined by its intended use. While a minimum thickness of 4 inches is generally recommended, 6 inches or more is often preferred for applications such as driveways, patios with heavy features, or slab-on-grade foundations to ensure adequate strength and durability.
