Concrete Driveways Suited for Newton’s Hillside Homes

Evaluating the Property and Slopes

The first step of a hillside project is the site evaluation. This primary evaluation will dictate the overall method of construction to ensure the site has the desired level of stability and will last for a long time. Contractors have to evaluate the slope of the property, the type of soil present, and the current drainage pattern of the area to identify any potential problems.

Analyzing Soil and Stabilizing the Subgrade

Due to extreme variations in soil stability in Newton, particularly in areas where there are large elevation differences, before placing concrete, the contractor needs to stabilize the subgrade to avoid slippage and settlement, two major causes of early concrete cracking. For these reasons, we frequently use soil stabilization and/or intense compaction methods to produce a solid foundation for the concrete pavement. Neglecting this groundwork jeopardizes the whole structure, causing substantial repair costs later.

Importance of Transition Points

Sloped driveways need to include carefully engineered transition points so that they can safely allow vehicles to come up the driveway and also provide a safe route during icy conditions. A transition point from one grade to another can severely damage low-clearance vehicles or create hazardous driving conditions. An experienced concrete contractor develops a gentle, smooth transition from the street to the garage apron, with consideration of the optimal angle of repose. By developing a smooth transition with the correct angle of repose, the contractor develops a safe and comfortable experience for the driver throughout the year, regardless of the grade of the driveway.

Customized Concrete Formulations for Durability

Ordinary concrete formulations fail quickly due to increased rate of erosion and freeze/thaw stresses associated with sloping applications. Because of this reason, customized, high-performance formulations are a required element in all applications.

Strengthened and Reinforced High-Strength Concrete

Because of the intense gravitational forces acting upon the site as well as shifting earth, hillside driveways require a stronger-than-average compressive strength. Due to this reason, we formulate our mixes with a higher cement content and a lower water/cement ratio, creating a dense and stronger finished product. Additionally, the incorporation of integrated steel rebar or wire mesh reinforcement is required, which distributes the loads and minimizes the likelihood of structural cracking occurring along the slope.

Winter Resistance Air-Entrained Concrete

Newton’s harsh winters result in numerous freeze/thaw cycles that rapidly deteriorate ordinary concrete. We use air-entrained concrete that incorporates tiny air bubbles that provide room for water to expand while it freezes. As a result of this unique feature, the concrete provides improved resistance to scaling and surface deterioration caused by ice, moisture, and de-icing chemicals. This is an extremely important component in the maintenance of the durability of the surface over the long term.

Incorporation of Advanced Water Management Methods

Water management is the single most important factor in determining the life expectancy of a hillside concrete installation. Without effective water management, excess water can cause erosion of the surrounding environment and compromise the base of the driveway.

Channel Drains and Trench Grates

In order to prevent water from traveling down the length of the pavement, effective drainage elements must be strategically incorporated into the design. Channel drains and trench grates are commonly used at the bottom of the driveway and at strategic transition points to effectively collect water and direct it into a suitable stormwater management system.

Crown and Contour Design

As stated previously, the design of the topography of the concrete driveway is important in controlling water flow off the pavement rather than allowing it to travel down the hill. We design the driveway with a slight crown or other contours to promote lateral water flow to the integrated curb and gutter systems. By incorporating a crown or contour into the design, we develop a system that does not allow water to accumulate on the surface of the driveway, thereby eliminating potential slip hazards and long-term erosion.

Texture of the Surface for Safety and Traction

The steeper grades found in many Newton hillside driveways demand some form of texture to enhance traction for tires and footwear, especially when the driveway is covered in rain, leaves, or snow.

Broom Finish and Exposed Aggregate Finish

Although a smooth troweled finish may appear attractive, it is lacking in traction characteristics. In addition to providing a better surface for traction, we highly recommend high-traction finishes, such as a heavy broom finish or an exposed aggregate finish, to optimize skid resistance. The textures developed through these finishes create friction between the tires/shoes and the driveway that enhances the safety profile of the driveway. This enhanced safety is especially important during inclement weather in areas around Newton Center.

Compliance with Local Regulations

Hillside construction typically requires compliance with local regulations, including zoning, erosion control, and stormwater management, which vary significantly among villages in Newton. Through our extensive knowledge of these specific regulations, we assure each of our projects complies with local regulations, thereby reducing potential delays and fines. Further, this knowledge expedites the approval process, enabling us to begin work on your hillside concrete project immediately and with great efficiency.

When constructing complex structural and aesthetic projects, such as hillside driveways typical of many Newton residential properties, the selection of superior materials and detailed design is imperative. To successfully install a high-performance concrete driveway, you need to possess technical expertise, a comprehensive knowledge of hydrologic control, and a commitment to delivering superior quality products.
