The Advantages of Core Drilling for Survey Monument Installation

While jack hammering is a commonly used method for breaking through solid surfaces, core drilling offers several advantages over this technique, especially when it comes to survey monument installation. Here are some reasons why core drilling is considered superior to jack hammering:

1. Reduced Surface Damage: Core drilling causes minimal surface damage compared to jack hammering. Jack hammering involves forcefully breaking apart the surface, which often results in chipping, cracking, or shattering of the surrounding material. This can be particularly problematic when working in areas with delicate surfaces, such as decorative concrete, asphalt, or tiled surfaces. Core drilling, with its precise drilling action, minimizes surface disruption and preserves the integrity of the surrounding area.

2. Longevity and Durability: Core drilling exerts less stress on the surrounding pavement. The drilling process is vibration-free, minimizing the risk of further damage to the pavement and adjacent structures. In contrast, jack hammering generates significant vibrations and impacts that can propagate through the pavement, potentially causing cracks or shifting in the surrounding area. A core drilled hole, with its precise fit and reduced surface damage, contributes to the longevity and durability of the pavement. The tight seal created by the core drilled hole helps to protect the underlying layers from moisture penetration, preventing premature deterioration. Additionally, the minimal surface damage from core drilling reduces the likelihood of developing potholes or other pavement defects in the vicinity of the survey monument.

3. Speed and Efficiency: Core drilling is a faster and more efficient process compared to jack hammering. The specialized drilling equipment used in core drilling allows for swift and accurate hole creation. This results in reduced labor time and costs, enabling crews to complete installations more quickly, especially in larger projects or time-sensitive situations. Jack hammering, on the other hand, can be labor-intensive, time-consuming, and often requires multiple passes to achieve the desired hole size.

Core drilling offers significant advantages when it comes to survey monument installation. The precise and accurate placement, minimal surface damage, efficiency, versatility, and longevity make it an optimal choice for surveyors and construction professionals. By utilizing core drilling techniques, survey monuments can be installed quickly, securely, and with minimal disruption to the surrounding environment.
