What equipment is used to compact pavers into the bedding sand?

1. Hand trowel

2. Plate compactor

3. Power screed

4. Vibrating plate

The correct answer is: Plate compactor

The use of a plate compactor is essential when installing pavers as it ensures that the pavers are set securely into the bedding sand, creating a stable and level surface. This equipment operates by using a vibrating mechanism that compresses the material beneath, increasing its density and minimizing the potential for settling or shifting over time. Proper compaction is crucial for the longevity and aesthetic stability of the paving installation, helping to prevent issues such as uneven surfaces and shifting pavers due to weather or traffic. While the other equipment mentioned serves various purposes in landscaping and construction, they do not provide the same level of effectiveness in compacting pavers specifically. A hand trowel is more suited for tasks like mixing or leveling small amounts of material, not for compaction. A power screed is typically used to level or smooth out concrete or screed materials rather than to compact pavers. A vibrating plate may seem similar in function but is not the specific term for the compactor that is standard in paver installation; hence "plate compactor" is the appropriate terminology. Therefore, choosing the plate compactor aligns perfectly with the requirements of compacting pavers into the bedding sand effectively.
