What affects your interlock price in Ottawa
- Paver brand and style – premium Techo-Bloc, Permacon and Unilock lines cost more than standard concrete pavers.
- Base depth – a proper 10-12 inch frost-proof base costs more up front but prevents heaving in Ottawa winters.
- Removal of the old surface – tearing out existing asphalt, concrete or interlock is quoted separately.
- Drainage and grading – re-sloping away from the foundation or adding drainage raises the total.
- Site access and size – tight urban lots and small jobs cost more per square foot; larger driveways cost less per square foot.
- Custom work – borders, curves, inlays, steps and lighting prep add to the price.
