Holland Landing Helical Pile Installation for Decks and Additions

Foundations Suited to Holland Landing’s Established Streets

Holland Landing Village is mostly older homes on lots with mature trees and finished yards, which makes a wide excavation the last thing anyone wants for a deck or an addition. We bring a compact helical pile rig in through the side yard instead, install the piles, and leave the lawn mostly as it was.

Properties nearer the Holland River can carry different drainage conditions than the rest of the village, so we walk each site before pricing it rather than assuming one plan fits every address.

Sand, Silt, and River-Adjacent Ground

Holland Landing sits on a mix of sandy soil and finer material like silt and clay, and that mix does not stay consistent from the village core out to the rural edges. Land closer to the Holland River tends to hold more moisture, which changes how a shallow footing would perform there compared to higher, drier ground along the Yonge Street corridor.

Why That Matters for Pile Depth

We do not apply one depth to every Holland Landing property. Each pile is driven and torque-checked until it reaches soil capable of carrying the structure, whether that is a village lot or a rural property with a longer driveway.

Permits and Engineering for Holland Landing

Holland Landing is part of the Town of East Gwillimbury, so its building permits and review process go through the same department.

Project Item What drives it Holland Landing details
Building Permit Structure type, floor area, and scope of work.

New builds, additions, garages, and most decks require an approved permit through East Gwillimbury. Check the Town’s building permit requirements before you plan the project.

Deck Exemption Height above grade and roof coverage.

An uncovered wooden deck under 600 millimetres above grade, clear of any required exit, is exempt from a permit under East Gwillimbury’s guidance. Taller or covered decks need one.

Site Access Driveway width, gates, and distance to the work area.

Compact equipment lets us reach many Holland Landing lots that a larger excavator could not, village or rural.

Working with Trevor and his team has been a seamless and stress free experience. They aligned with our vision and transformed our space quickly and efficiently. We are new to the technology of helical piles and were unsure of what they are capable of. Trevor was thorough and confident with his explanation; the effectiveness and ease of installation sold us! We are excited to enjoy our new sunroom addition and deck for years to come without worry of foundation or footing issues.

While planning a deck build for a friend, I reviewed the planning and steps needed for the 6 nessesary concrete piers and flared bottoms. It was going to be a big job. A friend recommended DiamondTech and after getting the quote, it was a no brainer to move forward with helical piles. Great communication from Chelsea, and very accurate and professional install team. Could not be happier.

In the beginning phases of a project we were working on we noticed the supporting posts of the upper deck had become rotten and unstable during excavation. Our client was concerned about delays this may cause to our project. I reached out to the team at DiamondTech Piles and connected them with our client. Our client had a quick and detailed conversation, received a quote and a timeline to deal with the urgent matter. The crew at DiamondTech were punctual, courteous and accommodating while they worked along side our crew. Communications with us and our client was clear and accurate. I would highly recommend DiamondTech if you are looking for solutions for your upcoming projects

Excellent. Professional. Right on time. Right on the money. Helical piles are the best option and these guys are the right choice. Many thanks for the excellent work! I had to add a note about the customer service! Our project started and all of a sudden we realized the saddles that receive the beams were not the 8 inch we needed.....cue panic! . I reached out to the team and the search was on! And in less than 1 hours the replacement parts were delivered. It was unbelievable to witness the commitment to customer service. Especially from the mother ship! ( you know who i mean). This team means it! And we grateful that our brain gap was was remedied!

Trevor and his team from Diamond Tech Piles installed the helical piles for our deck and did an excellent job. They were professional, efficient, and clearly knew their work. The process involved some digging and machinery, but they took great care to minimize any impact and left the property in much better condition than we expected. We’re very happy with the results and would absolutely recommend Diamond Tech Piles to anyone needing helical pile installation.

Very positive experience. Trevor was very responsive and polite - a real delight to work with. With his team, they drove helical piles around our existing pool for our new deck. We definitely ran into obstacles with rocks, buried cement, roots and the cement pool collar, however, they found great solutions. I have absolutely no hesitation with recommending Diamond Tech Piles - they are great!

Trevor and Zee installed 4 SP3 helical piles for us today for a gazebo. Saved our backs versus digging concrete piers, and gave us the peace of mind with the torque reports. It was great dealing with Trevor throughout the process, especially as a first time helical pile user who had a lot of questions. Highly recommend!

The crew installed very large helical piles for us to build our cottage on. The owner Trevor was very responsive and got the job done by organizing a barg, to bring their equipment to our remote location. It was a great experience all around.

Trevor and his guys were awesome. Originally planned helical pile installation for late April, but when deck contractor schedule changed, they went above and beyond to get job done weeks sooner to assist. Thank you for your accommodation, very much appreciated!!

The soil there can hold more moisture than higher ground in the village, which is one of the things we check on site before setting a depth.

Yes, our rigs are sized for narrow side yards and gated properties, which covers most of the older village lots.
