Question 1

How many pavers do I need?

Accepted Answer

Divide total patio area by the coverage area of one paver and add 5-10% for cuts and waste.

Question 2

How thick should the base be?

Accepted Answer

Commonly 4-6 inches of compacted gravel plus 1 inch of sand; adjust for soil and climate.

Question 3

Do I need edge restraints?

Accepted Answer

Yes—edge restraint keeps pavers locked and prevents spreading.

Question 4

How do I estimate material cost?

Accepted Answer

Multiply quantities (pavers, gravel, sand, edging) by unit prices and add delivery or equipment rental if applicable.

Question 5

Should I slope the patio?

Accepted Answer

Yes—about 1/4 inch per foot away from structures for drainage.
