Finishing touches
Edge restraint along every open side keeps the pavers from spreading. After compacting the pavers, sweep polymeric or joint sand into the gaps.
Slope and drainage
Patios should slope away from the house about 1/8 to 1/4 inch per foot so water does not pool against the foundation. Build the slope into the compacted base so the sand bed and pavers stay a consistent thickness.
Measuring the patio
Measure the patio in feet and multiply for square feet. For L-shapes or curves, split the area into rectangles and circles and add them. Mark the outline with paint or string first so your numbers match the real layout.
Ordering materials
Pavers often come by the pallet, and a pallet’s coverage is printed on the product sheet. Order base and sand at the same time to save delivery fees. Keep a few extra pavers from the same batch for future repairs, since color can vary between batches.
