What this means for concrete work
Population growth of more than 14% in five years means new homes and new driveways, patios and walkways. New-build owners often upgrade a basic builder driveway or add a patio. See concrete patios and concrete driveways.
Sandy soil can drain well, but sand can also shift if it is not properly compacted. Neither soil type removes the need for a compacted granular base, good drainage and an exterior-grade mix. The soil on your lot may differ from the regional description, so ask your contractor how they will test or assess the ground.
Much of the municipality is rural, so lots are often larger and driveways longer. Longer driveways cost more per project, and a long run raises questions about drainage, culverts and joint spacing. See the cost guide.
