Engineered to support 4,000+ lbs. Our reinforced hot tub pads provide the perfect level foundation for your backyard oasis.
A filled 6-person hot tub weighs 4,000-5,000 lbs that's the weight of a small car! Your foundation must be engineered to handle this load safely.
A concrete pad is the only foundation that provides the strength, stability, and longevity your hot tub investment deserves.
Our 6-inch reinforced pads support 4,000+ lbs without cracking or settling. Engineered for hot tubs weighing 80-125 lbs per square foot when filled.
Laser-leveled to within 1/4 inch. Hot tubs require a level surface for proper operation, even water lines, and to maintain your warranty.
Slight slope around the perimeter directs splash water and rain away from your home. Prevents pooling and ice formation in winter.
Air-entrained concrete handles Canadian winters without spalling or cracking. Your pad stays smooth and solid year after year.
Properly installed concrete pads last decades with zero maintenance. Far outlasts your hot tub and any alternative foundation.
Most hot tub manufacturers require a concrete or equivalent foundation for warranty coverage. Protect your investment properly.

Add 12-24 inches to each accessible side for safe entry/exit. Consider electrical access (most tubs need 220V), gas line routing for heaters, and access panels for service. We can coordinate with electricians if needed.
We assess drainage, access, proximity to electrical, and soil conditions. We verify your hot tub dimensions and recommend optimal pad size.
We excavate 12-14 inches deep for proper gravel base and 6-inch concrete thickness. All soft spots are addressed.
6+ inches of crusher run gravel is installed and machine-compacted in lifts for maximum stability and drainage.
Wire mesh or rebar grid on chairs, positioned in the center of the slab for maximum load distribution.
32MPa air-entrained concrete, vibrated to eliminate voids. Laser-leveled for perfectly flat surface.
Full 28-day cure recommended before hot tub placement. We coordinate timing with your tub delivery.
