This site is under consruction
for overlaying of damaged concrete and asphalt driveways, pavements, etc.
Installing of overlay topping layers solve restoration of driveways and provide a wide variety of finishes. As it known, all they have one basic requirement: The slab beneath must be structurally sound with a bondable surface. In most cases it requires removal of old concrete driveway slab with its cables, drainage pipes and water mitigation systems.
Technology of PATCHCRETE application does not require replacement of old concrete. Preliminary spray of KALMATRON® KF-G provides regeneration of aged concrete with bondable surface. Overlay by PATHCRETE with thickness beginning from 5/16” or 8 mm results in following benefits:
Courtyard concrete damaged by winters blistering and deicing treatments by the salts and sand.
PATCHCRETE pumping with slump of 3 1/2" or 9 (cm) with pumpability up to 45' or 15 (m).
PATCHCRETE placement by 3/4" or 18 (mm) on damaged concrete by the screed with vibrating.
PATCHCRETE textured to be
protected from shear wearing.
Overlay by PATCHCRETE stamped by
pebble rock technique after 5 years.
At left and at right are shown concrete's and PATCHCRETE's surfaces with and without shrinkage cracks respectively.
The chart between them is about differences in drying shrinkage between HP concrete with SILICA FUME and KALMATRON® based PATCHCRETE.
Almost 2 times difference results in zero shrinkage cracks on PATCHCRETE surface.
Core specimens of PATCHCRETE at left shows excellence of concrete structure compaction. As a result, corrosion resistance of HPC and
PATCHCRETE to 15% SULPHURIC ACID differs by 22% which prolongs concrete durability by 2 times.
PATCHCRETE cost is about 3 times less than the cost of High Performance Concrete with SILICA FUME.

We supply PATCHCRETE mix design and admixtures KALMATRON® KF-A or Krete100® and KALMATRON® KF-G by 50 LB plastic bags for preparation on a job site by mixing with water. Application is simple requiring general knowledge of concrete placement jobs. PATCHCRETE is liquid impermeable and corrosion resistant with wide range of applicability for overlay of the swimming pools, ponds, oil wells, septic tanks, etc.
