Colpatch is a storage grade macadam that is ideal for instant,
high quality repairs to bituminous or concrete surfaces.
Colpatch can be used for carriageway repairs, patching,
reinstatements and temporary surfacing.
Colpatch provides an immediate solution to potholes in roads,
drives, car parks and many other surfaces.
Colpatch is formulated from penetration grade bitumen,
proprietary Macfix additive supplied by Macismo Asphalt &
Innovations and selected aggregates.
Why use Colpatch?
Safe and Easy to use. Colpatch has a long storage life, up to
two years. Colpatch is cold applied and safe to handle. No mixing
- Patches potholes in bituminous surfaces
- Reinstates trenches in trafficked surfaces
- Easy and quick to use
Colpatch is available in 20kg plastic buckets and 25kg sealed
bags. It can also be supplied pre-packed on pallets, in 1 tonne
bulk bags or in bulk open loads.Workability can be ensured even in
cold weather by simply manipulating the Colpatch.
Ensure that the surface to be repaired is clean and free from
loose material, oil, grease and standing water.
To achieve a long lasting repair it is recommended that the base
surface is primed with Colas Leotak. Vertical edges of the area to
be repaired should be formed as far as possible and then treated
with a Colas Bitukold edge sealant prior to forming joints. For
small potholes, Bitukold may be used over the surface area of the
hole as a tack coat. However a quick repair can be performed
without any cutting out, tackcoats or edge sealants.
Apply sufficient Colpatch to over-fill the area to be
reinstated, ensuring that all corners are filled by gently needing
the material with a shovel to evenly spread it across the full
Compact the material to the surrounding level using a hand
tamper or compactor/roller. For large areas and deep sections, use
a vibrating plate or roller slightly wetting the drum with water.
If under-filling has taken place, simply add more product and
compact to level.
It is recommended that deep patches should be built up in
15-40mm compacted layers as this will result in better compaction
Once compacted the Colpatch is ready to be trafficked.
Colpatch remains flexible for some time after application.
Because the material will take up the contours of potholes
naturally and form an immediate repair, it is ideal for irregularly
Curing is brought about by both air drying and compaction. The
rate of cure is dependent upon temperature and the weight and
volume of traffic. However, under normal traffic conditions,
Colpatch will not depress, track or pick up during the curing
Spread Rate Guide
The table shows the approximate rate of spread of various
compacted thicknesses of Colpatch. Please note that the covering
capacity of Colpatch may be affected by such factors as the density
and grading of the aggregates, condition of the substrate and final
state of compaction. On more irregular substrates, heavier rates of
spread are to be expected.
