Land Grading

What is Land Grading and Why is it Important?

Land grading is the leveling of land by either spreading out dirt or adding in more dirt to create an even surface – it is also one of the most important components of a construction project.

Once the land is cleared, this intrinsic step must take place as it helps prevent possible future damage caused by water drainage issues and erosion. It is important to remember, as well, that even if your property is already built, we can still work to ensure these issues don’t occur.

Solving Drainage Issues

Most times when construction is taking place, the ground is not a level surface throughout. Therefore, the land must be graded correctly in order to ensure that water will be channelled away from the building or structure – after all, you wouldn’t want your basement flooding, would you?

A proper team, like the proficient group at Osborne Construction, will ensure that the area is properly marked out and that proper drainage channels are created. This ensures that in the future when heavy rainfall occurs, the water will flow away from your structure, as opposed to pooling within or around it.

TYPES OF DRAINAGE PATTERNS

Split Drainage Diagram

Most drainage types can be recognized by two different patterns; ‘Rear to Front Drainage’ and what’s known as ‘Split Drainage.’ For split drainage builds, the front of the property is drained to the municipal road in front of the property whereas the rear of the lot is drained towards the rear of the property.  A portion of the rear drainage will naturally enter onto neighboring properties that use rear to front drainage.  Please note that rear to front drainage lots will handle larger volumes of water due to flows from neighboring lots.

Apron Swales:

Typically 3 to 5 meters from the back wall of the house on the lot. This swale runs parallel to the back wall of the house across the width of the property and connects to the side yard swales to direct water to the road.

 

Sheet Drainage:

All lot surfaces are designed and constructed to water in a particular direction away from the house which in known as the slope or grade.  Sheet drainage allows for rainwater to flow to a lower elevation with the ground absorbing some of the rainwater as it flows.  This is also know as infiltration.

Connected Swales Example

Connected Swales:

For urban subdivisions the lot sheet drainage is mostly directed to swales on the common property line.  A swale is a “V” shaped channel in the ground that connects the sheet drainage flows and efficiently directs water to an appropriate outlet, whether that be a public road or other infrastructures.

Eavestroughs and Downspouts:

Rainwater and melted snow falling onto the roof of a home is collected by eavestroughs and directed to the ground directed by downspouts.  Downspouts may be connected into the storm sewer or may drain directly onto the property.  If downspouts are not connected to the storm sewer, they should run into an extension pipe and/or splash pad to keep water moving away from home.

Solving Erosion Issues

If interior flooding wasn’t bad enough, improper grading can also lead to erosion of the land that is surrounding your building, and also the land your building is built on. Steep slopes, and even small bumps in the land, can lead to an unstable foundation that eventually erodes due to various environmental factors such as excess water or wind.

Osborne Construction assures you that our team properly compacts the surface area in order to limit the risk of erosion.

After having three previous contractors guess what is causing a leak through my garage wall, Mark determined in 10 min.... where and how the leak was occurring. By simply placing a small twig in a hole at the base of the front wall, he was able to demonstrate very quickly the primary entry point of rainwater. Because of his expertise, the work was completed at 1/4 the cost of other estimates and on time. Steve (Waterloo)read more

Marc and I installed a large geothermal system in the fall of 2019. The hard, hard clay made it take longer than either... of us expected, which led to some scheduling conflicts. Marc handled this well and got everything finished with only a small delay. He was well prepared, worked long hours and at times went above and beyond to ensure a professional result. I would happily recommend Marc to anyone looking for light-duty excavation services.read more

Client Testimonials

"Mark and his team did a great job on our new landscaping project. They dug out and prepared new flower beds for planting, prepared sidewalks for flagstones, and helped with drainage issues on the driveway. Their expertise and attention to detail are just what we needed so we could do the next steps of the project ourselves. I would highly recommend this business for any exterior work!"

Osborne construction did an excavation, fill, and concrete job on over 5500sqft of driveway and patio space around my home. He finished on schedule, and left the job site clean and ready for the next phase. They're easy to communicate with, and are very knowledgeable. I would highly recommend them. !
