What else can I help you with?
Can you pour concrete over existing rock?
Concrete need a uniform and compacted base, so as long as that rock is uniform and compacted, you should be fine.
Should you pour a concrete sidewalk without crushed stone?
Pouring a concrete sidewalk without a layer of crushed stone is not recommended. Crushed stone provides essential drainage, helps prevent moisture buildup, and creates a stable base that reduces the risk of cracking or settling over time. Without it, the concrete may be more susceptible to damage from water and temperature fluctuations. For best results, always include a proper base layer of crushed stone.
How do you use concrete bonding agents?
Concrete bonding agents are used to enhance the adhesion between new and existing concrete surfaces. To use them, clean the surface of the existing concrete to remove any dirt, dust, or loose particles, then apply the bonding agent according to the manufacturer's instructions, typically using a brush or roller. Once the bonding agent is dry, you can pour or apply the new concrete mix over it, ensuring a strong bond between the layers. Always follow the specific guidelines provided on the product for the best results.
What the best way to seal concrete?
It all depends on what the concrete is used for. If it's a footing or foundation that's in direct contact with, and buried by, surrounding earth, you can use heavy duty (6 mil) poly sheeting, or glop asphalt/tar all over it. If you're talking a sidewalk, driveway, stairs, or some such visible surface with foot or vehicle traffic, you want to use a penetrating sealer---concrete sealer, or Thompson's Water Seal.
Can you lay vinyl flooring over old vinyl flooring on concrete?
If you cant get the existing flooring up, or if lifting it would cause more damage to the substrate then its worth, then yes i would suggest doing this and it is common practice.
Why is it easier to push a crate over a smooth concrete sidewalk than over grass?
There's less friction over a smooth concrete sidewalk
When pouring concrete sidewalk do you use gravel?
Yes, using gravel is recommended when pouring a concrete sidewalk. Gravel serves as a stable base, providing drainage and preventing moisture buildup that can lead to cracking. It also helps to distribute the weight of the concrete evenly and minimizes settling over time, ensuring a longer-lasting sidewalk.
What causes big cracks in the sidewalk?
Big cracks in the sidewalk can be caused by a variety of factors, such as tree roots pushing up underneath the concrete, soil erosion beneath the sidewalk, or the natural settling of the ground over time. Changes in temperature, especially freeze-thaw cycles, can also contribute to cracking by expanding and contracting the concrete.
Why is it easier to push a crate over smooth concrete sidewalks than over grass?
It is easier to push a crate over smooth concrete sidewalks than over grass because grass offers more resistance due to its uneven and soft surface. The smooth concrete surface reduces friction and allows for smoother movement of the crate.
Can pavers be installed over concrete surfaces?
Yes, pavers can be installed over concrete surfaces by using a sand bed or mortar to secure them in place. This can provide a new look and improve the durability of the existing concrete.
Can you pour concrete over existing rock?
Concrete need a uniform and compacted base, so as long as that rock is uniform and compacted, you should be fine.
Over time how might the grass growing up through a crack in a sidewalk affect the sidewalk Use the terms and ldquophysical weathering and rdquo and and ldquochemical weathering and rdquo in your answe?
The grass growing through a crack in a sidewalk can contribute to physical weathering by exerting pressure on the concrete as the roots expand, potentially widening the crack. Additionally, the roots can facilitate chemical weathering as they release organic acids that can weaken the sidewalk's structure over time. Ultimately, this combination of physical and chemical weathering can lead to further deterioration of the sidewalk.
Can you install ceramic tile over stained concrete and if so what is the preparation for the existing concrete?
Bead blast or score the concrete first anything from a wire brush to a floor sander might work...be VERY CAREFUL with the dust though

Can the police tow your car in your driveway if it is blocking the sidewalk?
Yes, blocking the sidewalk is illegal and if it is over the sidewalk it is not legally parked in your driveway.
What would expect to happen to a sidewalk over the course of years when rainwater continues to soak in to concrete and freeze?
If water is allowed to get into a concrete sidewalk and not allowed to drain and it freezes, the expansion of the water/ice as it crystallizes causes the concrete to crack. If more water settles in the crack and freezes, the crack gets bigger. Each year the increase in the size of the crack is greater because a greater amount of water can fit in the crack, and a greater amount of water has a greater amount of expansion when it freezes.
What happens when you put cheese on a sidewalk?
If you leave the cheese on the sidewalk over 7 days it will turn white.
