Best Gym Flooring for Uneven Concrete Garage Floors
Don't let a bumpy floor ruin your heavy lifts.
2/7/2025•Editorial Team
Most UK garages weren't built for precision lifting; they were built for cars. Rough, sloping, or pitted concrete can make a squat rack unstable or cause deadlifts to roll. Here is how to level the playing field.
The Problem: Pits and Slopes
If you just throw down thin foam tiles on bumpy concrete, they will separate and slide. For a safe gym, you need a sub-floor that bridges the gaps.
Solution: 17mm+ Horse Stall Mats
Thin gym tiles follow the contour of the floor. Heavy-duty 17mm or 20mm rubber 'stable mats' are rigid enough to bridge small pits and bumps. They are heavy (20kg+ each) so they don't slide around even on a slope.
For Severe Slopes: The Platform
If your floor has a severe drainage slope (common in new builds), do not shim the rack legs as this creates pressure points. Build a level plywood lifting platform. The wood absorbs the angle, giving you a flat surface for the rack to sit on.
