SikaGrout®-285

CEMENT-BASE FLUID EXPANDING MORTAR, WITH HIGH MECHANICAL RESISTANCE

One component cement base mortar with high mechanical resistance. It is supplied ready to use, only by adding water.

Sikagrout® -285 has the following properties:
▪ Easy mixing and placing in cast.
▪ Good flow characteristics and pourable with Self-lev-elling.
▪ Free from chlorides and metallic particles. It does not oxide in contact with humidity, it protects metallic parts against corrosion, due to its basic PH
▪ Slightly expanding.
▪ High mechanical resistances and quick resistances development.
▪ Excellent concrete, mortar or steel adhesion. It provides a monolithic joining and impact and vibra-tion resistance.
▪ Waterproofing: water and oils resistant.
▪ It is neither toxic, nor corrosive.

Usage

Sikagrout® -285 is indicated for all of uses that need high initial or final high mechanical resistances:
▪ Bearing plates, machine foundations and anchors.
▪ Metallic elements (reinforcements, etc.), concrete posts and pre-cast construction columns.
▪ Cavities, gaps and recesses into the concrete mass filling.
Note: Do not use for surfaces levelling.

Application steps

MIXING

Pour the water in the recommended proportion into a suitable mixing container. While stirring slowly, add the powder to the water. Mix with low speed (< 500 rpm) hand drill mixer to avoid entraining too much air. Mix thoroughly at least for 3 minutes until homogenous with no lumps. Mix only full bags for best results.

APPLICATION

Stand the grout for ~2-3 minutes; stir with a trowel and then pour into the prepared openings. For more information on pouring techniques refer to Sika Method Statement

CURING TREATMENT

Protect the fresh material from premature drying using an appropriate curing method e.g. curing compound, moist geotextile membrane etc.

CLEANING OF EQUIPMENT

Clean all tools and application equipment with water immediately after use.
