Bison Level.Up System Adjustable Deck Pedestal Kit
The Bison Level.Up system is a 12-pack pedestal set designed to attach to wood joists and replace digging concrete footers. It enables building a ground level deck up to 8 ft by 10 ft over concrete or compact soil using 2×6 pressure treated lumber. Each pedestal supports up to 750 lbs, offering sturdy substructure support for moderate decks. Best for homeowners seeking a fast, footer-free solution for low-profile decks close to grade. Caution: ensure soil and joist layout meet load needs and local codes.
24 Pack Adjustable Deck Support Pedestal Kit (MCCKLE)
These adjustable pedestals are crafted from durable polypropylene and feature a screw ring for height settings from 1-3/16″ to 2-3/8″. They promote level decking on uneven ground, enhance drainage, and create space underneath for ventilation or storage. Each pedestal is engineered to support over 1000 lbs with reinforced threads to stabilize deck panels. Best for larger flat or gently sloped spaces where you want a robust, ventilated underdeck area. Limitation: ensure the footprint works with your joist spacing and deck size.
33″ Decking Waterproof Wood Composite Platform
This 33-inch decking module uses anti-slip composite surfaces with low maintenance needs. Height adjustability ranges from 20 cm to 26 cm, and the modular interlocking design lets you assemble a square deck area that adapts to patios, gardens, or campsites. Best for quick, modular ground-level decks that require a stable, weather-resistant surface. Caution: module size may require multiple units to cover larger areas.
50 Pack Deck Block, Adjustable Deck Support
These plastic deck blocks are adjustable from 18 mm to 30 mm with a screw ring, offering versatile leveling for sheds, decks, or pathways. The blocks feature a vented design to prevent water buildup and support substructures made of wood, WPC, or metal. Best for large-scale projects requiring many leveling points and open space beneath the deck. Limitation: check compatibility with your joist layout and ensure adequate ventilation under the deck.
Deckit 12-Pack Adjustable Pedestals
Deckit pedestals are UV-resistant and designed for 2×4 and 2×6 joists. They offer stable leveling from 1.18″ to 2.36″ and support up to 1000 lbs per pedestal. Best for patios, sheds, and low decks needing precise leveling without heavy digging. Use caution to verify height range matches your terrain and that the system integrates with your joist spacing.
Buying Guide
What to consider when choosing ground level deck kits
- Load requirements: match pedestal or block capacity to your deck size, joist spacing, and anticipated furniture. Higher capacity provides stability for larger setups.
- Soil and substructure: consider whether you’ll place over compact soil, concrete, or uneven ground. Some systems emphasize drainage and ventilation under the deck.
- Height range: ensure adjustable height covers the ground profile and desired deck height above grade. Narrow ranges may require extra components.
- Materials and durability: look for UV-resistant, weatherproof plastics or corrosion-resistant polymers that resist freeze-thaw cycles.
- Modularity and expandability: modular panels or pedestals allow future expansion or reconfiguration without replacing the entire system.
- Installation footprint: measure footprint area to determine how many pedestals or blocks are needed for even support across the deck.
How to plan your deck layout
- Mark joist locations and confirm footing sites before assembly. Use a level and string line to ensure a truly flat deck surface.
- Pair pedestals with compatible joists (2×4 or 2×6) and consider under-deck ventilation if you plan storage or water drainage.
- Factor future additions or changes, such as adding more sections or extending the deck area, into your initial pedestal count.
Installation tips
- Follow product-specific height adjustments in small increments to avoid over-tightening or misalignment.
- Check for level after each pedestal adjustment to prevent deck wobble or uneven gaps between boards.
- Test load on a small area before completing the entire deck to ensure stability and alignment.
Maintenance considerations
- Periodically inspect pedestals and blocks for signs of cracking or deformation, especially in freeze-thaw climates.
- Keep drainage paths clear to prevent water pooling under the deck surface.
- Clean surfaces with water and a mild detergent to remove dirt and debris that may impact sliding or leveling performance.
FAQ
- Q: Do ground level deck kits require professional installation? A: Many kits are designed for DIY use, but confirm your local building codes and homeowner association rules before starting.
- Q: Can these systems support outdoor furniture and grills? A: Yes, when the load rating matches the deck size and spacing; avoid overloading any single pedestal.
- Q: Are these kits suitable for all terrains? A: They work best on compact soil, concrete, or evenly graded subgrades; uneven rock or deep slopes may require site prep.
- Q: Do I need a moisture barrier under these systems? A: It depends on the subsoil and climate; some setups benefit from breathable underfoot materials to improve drainage.
- Q: Can I reuse pedestals if I relocate the deck? A: Many pedestal systems are reusable, but verify with the manufacturer’s guidance for relocation.
- Q: How do I choose the right height range? A: Measure the current ground level, desired deck height, and consider future under-deck storage or ventilation needs.
