Do you need gravel under concrete?
Whether you pour concrete for a walkway or patio, a strong gravel base is required to prevent the concrete from cracking and shifting. Gravel is especially important in clay soil because it doesn’t drain well, which results in water pooling under the concrete slab and slowly eroding the soil as it finally drains.
What do you use for curved concrete forms?
Masonite siding has often been an option for forming curves — it’s stiff, yet bendable. Landscape edging material made out of metal is what some contractors use because it’s easy to find. “Kerfs” or grooves in two-by-fours allow the wood to bend, or rip thinner plywood to the desired height.
Is it OK if it rains after pouring concrete?
Heavy rain can cause problems to freshly poured concrete as it can wash out some of the cement from the mix. This can weaken the surface of the concrete, making it a softer consistency and decreasing the strength of the concrete.
