How do you make a sloped concrete ramp?
To create the slope of the ramp, build the sides of the form with pieces of plywood cut at an angle along the top. The key to shaping the concrete into a slope is to use a stiff mixture; if the concrete is too wet, it will slump down to the bottom of the ramp, seeking its own level.
How do you stop rising damp on a concrete slab?
Rising moisture occurs when ambient temperatures rise, which draws moisture up from the ground and through the concrete. One way to avoid this is by placing a Damp Proof Membrane (DPM) between the concrete and the ground. This will prevent wet spots from forming.
How do you seal a shed to concrete?
Once you’ve poured your concrete slab and your garden shed is up, use a silicone sealant like Brick & Concrete Silicone or any other silicone sealant that you prefer, to seal around the inside base of your shed to further improve its water resistance.
Does a shed base need a damp proof membrane?

Can you pour concrete on top of concrete?
