HIGH STRENGTH PILE CAP CEMENTITIOUS LEVELING GROUT
A single component, ready to use, which requires simple addition of water to produce a non-shrink, flowable and consistent grout repair material for filling voids and pile cap re-profiling. ESPOCEM PC is composed of high resistance hydraulic binder, graded high quality selected aggregates, and special additives, which control shrinkage and reduce water demand.
ESPOCEM PC is supplied in 25kg bags.
If kept the in a dry covered place and into the original well closed packaging, the product will have a shelf life of 12 months.

The boundary of the repair area should be cut using a concrete saw to provide a neat edge to the damaged area with no feather edging. The area to be repaired may then be broken out up to the prepared boundary. The substrate should be perfectly cleaned, free from dust, inconsistent parts, traces from stripping oils, efflorescence, rust, etc.
Repairs using ESPOCEM PC should be applied in layers up to 25 mm in depth. ESPOCEM PC may be applied for greater depths depending on the design of the structure being repaired.
All reinforcement, which shows signs of corrosion must be fully exposed to an adequate depth behind the bar in order to allow ease of access for the fluid repair compound. The steel bars should be grit blasted to bright metal. Immediately after the cleaning of steel bars is completed, coat the bars with BETOFER or EPOZINC as a protection layer to prevent further corrosion. After application of the protective materials, allow the coated steel to dry before commencing with the repair application.
Use proper formwork to be able to cast the flowable mix. The formwork should be rigid and tight to the substrate to prevent movement and grout loss. It is advisable to use silicon sealant around the edges of formwork to prevent grout loss. To ensure that water is not absorbed from the repair material by the formwork, the interior faces of the formwork should be coated with DISARMANTE release agent. Normally, it will only be necessary to saturate the surface with clean water in order to prevent possible backwater at the moment of application
To prepare the grout, pour into container about 3.5 Liters of water then slowly add the content of the bag of 25 Kg. of ESPOCEM PC and mix till obtaining a homogeneous product using a slow speed electric drill attached with proper paddle to obtain the full benefit of the fluidity provided.
Apply ESPOCEM PC immediately after mixing. Grout should be poured only from one side of the formwork to eliminate the entrapment of air. This can be achieved by pouring the grout across the shortest distance.
Any exposed areas not covered by formwork must be cured using a proprietary curing compound, such as BETOCURE, or covered with clean wet Hessian cloth and kept moist until grout surface is ready to be finished. Once the formwork is removed, the total repaired area should be cured by the same process.
All used tools should be cleaned with water. Cured material should be removed mechanically.
For application during days of high temperature (+35⁰C or above) the following instructions should be followed:
ESPOCEM PC is a cement-based product is a cementbased product. During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.
In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly. If ingested, obtain medical attention immediately. Do not induce vomiting.
