Drilling & Blasting Questions answered
-
Drilling and blasting are two separate steps that work together to safely remove solid rock.
Drilling involves creating a precise pattern of holes in the rock. The size, depth, spacing, and location of these holes are carefully planned based on the project and rock conditions.
Blasting is the controlled use of explosives placed within those drilled holes to fracture the rock into manageable pieces. Rather than one large explosion, blasting is a carefully timed sequence designed to break rock efficiently while minimizing vibration and other impacts.
-
Blasting is often the safest and most efficient way to remove solid bedrock for foundations, roads, utilities, and other construction projects. Proper blast design helps achieve the required rock fragmentation while minimizing impacts beyond the work area.
-
Yes. Professional blasting is carefully planned before any work begins. Each project is designed to safely break rock while minimizing vibration, noise, and other impacts on the surrounding area. Safety is our highest priority, and every blast is carried out using industry best practices.
-
It’s common to feel vibrations during a blast, but feeling vibration does not necessarily mean damage has occurred. Professional blast designs are meant to control vibration and protect nearby structures. Every project is carefully planned based on site conditions to help minimize impacts.
-
Blasting vibration is created when energy from a blast travels through the ground. The primary purpose of a blast is to break solid rock, but a small amount of energy naturally travels beyond the blast area as ground vibration and air pressure. A well-designed blast focus as much energy as possible into breaking the rock, helping to minimize the amount of energy that travels into the surrounding ground.
-
People are naturally very sensitive to vibration. It’s possible to notice or feel a blast even when the vibration is well below levels associated with structural damage. Feeling a blast is a normal part of the blasting process and doesn’t necessarily indicate a problem.
-
Every successful blast starts with careful planning. Before any drilling or blasting begins, we evaluate the site to understand the rock conditions, project requirements, nearby structures, and access to the work area.
Once the site has been assessed, we develop a blast plan that determines the drilling pattern, hole depths, timing sequence, and other project-specific details. We also establish appropriate safety measures and secure the blast area before work begins. Thorough preparation helps ensure the blast is completely safely, efficiently, and with minimal impact on the surrounding area.
-
Permit requirements vary depending on the project and location. We’ll help you determine what permits or approvals are required and guide you through the process if necessary.
-
We work with engineers who use specialized monitoring equipment that measures both ground vibration and air overpressure during blasting. These measurements help verify that blasting is performed within established guideline limits.
-
Flyrock is the term used to describe rock fragments that travel beyond the intended blast area. While it is a recognized risk in blasting, professional blasting contractors use detailed planning and strict safety procedures to manage and prevent it.
At Coastal Rock Removal, flyrock prevention begins long before the blast. Every project is carefully assessed to determine the appropriate drilling pattern, hole depth, burden, spacing, and explosive load. Blast mats are used whenever conditions require additional containment, and exclusion zones are established to keep people and equipment at a safe distance. Our commitment to careful planning, industry best practices, and strict safety protocols helps ensure every blast is carried out safely and efficiently,
-
Weather can influence how sound from a blast travels. Certain atmospheric conditions may make a blast seem louder than it normally would. When practical, weather conditions are considered during project planning.
-
When appropriate, nearby residents and property owners are notified in advance of scheduled blasting activities.
-
Every project is different. Smaller residential jobs may be completed in a single day, while larger commercial or quarry projects can take longer. During your estimate, we’ll provide a timeline based on your specific project.
-
Safety is our priority. Before blasting begins, the work area is secured, equipment is checked, and all required safety procedures are followed. The blast itself only lasts a short time, after which the site is inspected before work resumes.
-
We provide drilling and blasting for a wide range of projects, including:
Residential foundations and basements
New home construction
Commercial developments
Road construction
Trenching for utility installations
Quarry operations
Site preparation and land development
No matter the size of the project, we work with contractors, developers, municipalities, and homeowners.
-
Yes. Drilling and blasting can often be performed year-round, provided weather and site conditions allow for safe operations.
-
We proudly serve all of Nova Scotia and New Brunswick.
-
If your project involves solid bedrock that can’t be removed efficiently with standard excavation equipment, drilling and blasting may be the most practical solution. We can assess your site and recommend the safest and most cost-effective approach.
-
The cost depends on several factors, including:
The amount and size of rock
site accessibility
project size
drilling requirements
Because every project is unique, we provide free, no-obligation estimates.
