Installing a deck on screw foundations

The installation process to build the foundations for your deck is fast and relatively easy, depending on site conditions. Whether you’re building a deck on uneven ground, grass, or a slope, our ground screws for decking ensure a solid foundation without the hassle of traditional concrete piers or deck base blocks. Our installers are vastly experienced in dealing with any obstacles or unforeseen issues that may arise.

Contact us to review your decking plans

Get in touch and tell us your plans, dimensions and desired features (e.g. hot tub area), so we can discuss what we need from you and what you get from us. We will review your decking plans and communicate with you regularly to gather all the details we need. You will get our full support.

Decking layout design

We gather all the information we need, cost your project, and produce a layout for the foundations. The more information you can supply us with the easier the calculations and screw selection will be. Installing a deck on grass or other ground needs to be precise.

Inspection, testing, and preparation

We do an inspection of the ground, load test if required and prepare for the layout of the screws. Installing a deck has to be precise, and we not need to make sure not only the top surface is suitable, but we also check for underground pipes, wiring and other obstacles, which we will navigate.

Laying out the foundation plan for your deck

We carefully mark out the ground, align the spots, and measure out the length, width and heights to ensure that your decking foundations will be perfectly level. We may have to pre drill the ground for pilot holes to make installing the screws easier.

Installing ground screws for decking with a subframe

We quickly and accurately install the foundations, according to the layout, and if we are contracted to build a deck base we will then attach it to the screws. Our installers are highly experienced and use the latest ground screw machines and installation equipment.

Completing your brand-new deck

The final touches get added by whoever is completing your new decking; that’s you if taking on a self install diy project. You can be rest assured though that your ground screws for decking will last for many years, and you will enjoy many fun times outside on it.
