Settlement and Utility Repairs
Settlement is often caused by inadequate soil or base compaction. Other factors can be water in the base
or soil, too thick a layer of bedding sand, or washed out bedding and joint sand. Loose or inadequate edge
restraints will cause pavers to move apart. Pavers in uneven areas can be removed, the settlement
adjusted, and the units reinstated with no wasted paving materials or unsightly patches. If the base or soil
has settled and is stable, remove the pavers and bedding sand, place and compact additional base
material to the correct level, then add bedding sand. Bedding sand alone shouldn’t be applied to adjust
the level of the surface if its thickness exceeds 11/2 in. (40 mm). Concrete pavers can be removed for
access to underground utilities, and reinstated after repairs. When utility repairs are complete, fill the
trench with base material and compact it. Remove about 18 in. (0.5 m) of pavers on either side of the
opening, level the bedding sand and replenish as necessary. Reinstate the pavers, compact, fill the joints
with sand and compact the surface again, filling joints as needed. ICPI Tech Spec 6— Reinstatement of
Interlocking Concrete Pavements, provides step-by-step guidelines on removal and replacement of
concrete pavers.
Removing Oil Stains
Concrete pavers on driveways stained by oil leaking from
cars aren’t damaged by petroleum products, but the stains
can be difficult to remove. Stains should be treated as soon
as possible since the longer they remain on the surface, the
deeper they penetrate and the harder they are to remove.
Wipe excess oil from the surface as soon as possible and
apply liquid detergent. Allow it to soak for several minutes.
Then wash the pavers with hot water. Several treatments
may be necessary for particularly stubborn stains. Cleaners
specially made for removing oil stains from concrete pavers
are recommended since they yield good results. In some
cases, it may be simpler to replace the stained pavers with
new ones. Removing oil and many other stains are
discussed in ICPI Tech Spec 5—Cleaning and Sealing Interlocking Concrete Pavement. Cleaning and sealing
concrete pavers early in their life can make removing stains easier since sealers prevent stains from
soaking into the surface. However, the sealers may need to be reapplied from time to time due to wear
and weather. Concrete pavers should be cleaned prior to applying a sealer to obtain the best
performance and appearance. Your paver source can provide information on cleaners and sealers
specifically made for concrete pavers.
