Depending on the type of driveway and how it has been constructed will determine which repair is needed.
Segmental paving repair
If the driveway has been constructed with the correct preparation as we have stated previously, the process is to simply uplift the pavers, re level the sand bedding and replace the pavers. 2 people can do 20-50m2 of this in one day.
If the incorrect base method has been used, an example of this is laying pavers directly onto crusher dust. These pavers need to be uplifted, the top base layer needs to removed and replaced so the pavers can be rebedded into soft material for a level finish without paver movement. 2 people can do 20-50m2 of this in 3 days.
The repair cost is 3 times higher if the base materials are not done as indicated. Driveway paving with the incorrect preparation will have a shorter lifespan, which means you will need to repair more often.
A benefit of segmental paving with correct preparation is that it allows maintenance that allows affordable repairs to small areas.
Rigid paving repair
Paving on a reinforced concrete slab fixed by mortar or glue and grouted. This requires an uplift of the paver out of the mortar bedding, generally using a small jack hammer. Clean off the grout and relay the existing paver or new paver into a mortar bed and re –grout.
If below the concrete slab needs to be accessed a section of this can be cut out and replaced without any concern of colour mismatch to the concrete as the existing or new pavers will go over the top.
Concrete driveway repair
If there are areas of your concrete driveway that need to be replaced, you cut out the damaged area, place in expansion joints, and replace the concrete. Concrete colour changes in time and you can never match the colour of concrete unless its poured at the same time. This includes plain grey, stamped and stenciled concrete.
Regular driveway maintenance can avoid the need of repair in the longer term, ultimately saving you money.
