NON SHRINK CEMENTITIOUS GROUT FOR ANCHORING & FILLING
ESPOCEM is a blend of cement, silica sand, selected aggregate and chemical additives. When the product is mixed with water it becomes self-leveling nonshrinking and very fluid mortar, with high initial and final mechanical strength. The mix is flowable which makes it easier to apply in irregular spaces.
ESPOCEM has excellent characteristics of adhesion to the substrate, impermeability and flowable consistency. It is featured by thermal expansion coefficient similar to high quality concrete.
ESPOCEM is supplied in 25kg bags.
12.7 liters per 25kg bag.
Keep the product in dry and sheltered place into original well closed packaging. In these conditions, product shelf life will be 12 months from production date.

To prepare the mortar, pour into a cement mixer or into a container about 3.5 liters of clean water (according to required consistency) for every 25kg bag of ESPOCEM.
Mix for 5 minutes using mixer or drill machine fitted with suitable paddle till obtaining a homogeneous mixture, free from lumps.
The mixed 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.
Maintain a constant hydrostatic hand, preferably of at least 15 cm on the side where the grout has been poured, allow 10 cm clearance between the side of the form and the base plate of the machine.
Do not add extra water to the mix more than what specified. If the mix starts to harden, do not use the mix and prepare a new one.
ESPOCEM can be placed in thicknesses up to 25 cm.
The repair area shall be cured in accordance with good concrete curing practice and protected from drying winds. Curing shall be done with non-degradable curing compound BETOCURE AR. Alternately; a wet Hessian cloth covered with polyethylene sheet can also be employed.
ESPOCEM should be removed from tools and equipment and mixers with clean water immediately after use. Cured material should be removed mechanically.
The surface must be solid, compact, clean, free from dust, cement laitance, curing compound, oils, grease, etc. All loose parts of concrete should be removed. A coarse surface profile with the aggregate exposed is preferred.
Saturate the support with water several hours prior to grouting. Concrete surface should be only damped, with no free water prior to grouting in order to avoid possible water absorption at the moment of casting.
Base plate must be clean and free from oil, grease, rust, etc.
Formwork should be constructed to be leak proof as ESPOCEM is a free flowing grout. It should also include outlets for the pre-soaking water.
ESPOCEM is a cement-based 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.
