Description
CONCRESIVE 2200, is a non-slumping epoxy bedding compound and adhesive. It is a two pack, fine aggregate filled, fast curing mateiral, ideal for a variety of bedding, gap filling and concrete repair applications.
CONCRESIVE 2200 is a stiff but easily workable compound that can be applied by either trowel, spatula or knife. It cures to give high mechanical properties typical of epoxy compounds. It is resistant to oils, greases, petroleum, salts, many acids and alkalis and most commonly met corrosive media. It does not shrink on curing, and is designed to be used when cured from below freezing point to 60°C. Its impact resistance, and mechanical strength is greater than that of concrete.
Primary uses
For surface repairs of fine cracks and spalls. For gap filling, grouting, bedding fixtures etc. For repairs to arrisses without the use of form work. Wherever a thixotropic epoxy mortar is required.
Typical applications
- Bedding bridge beams or steel bridge bearings.
- Repairng surface defects or to honeycombing concrete in horizontal, vertical or overhead situations.
- Fixing slip bricks to concrete.
- Securing bolts into walls.
- Dowel bars anchoring.
- As a gap filling adhesive.
- Filling bolt pockets.
- Bedding tiles.
- Repairing concrete posts in-situ.
- Fixing of surface ports for crack injection.

Chemical resistance
CONCRESIVE 2200 has excellent resistance to the following: most aqueous systems, sewage, urine, fresh water, sea water, diluted and concentrated alkalis, diluted acids, sulphur gases, mineral, vegetable and animal oils and fats, ammonia and formaldehyde.
Application procedure
Preparation:
All loose particles, laitance, dust and grease etc., must be removed prior to applicaiton of CONCRESIVE 2200.
Mixing:
The 3kg pack has been designed to be readily mixed by trowel. Where more than one pack is to be mixed at a time, a Mixal portable mixer (HD5 model) is suitable.
Application:
Knife or trowel CONCRESIVE 2200 to the required level using the minimum of solvent on the trowel to aid workability. The surface may be finished smooth by use of a paint brush dipped in CLEANING SOLVENT NO. 2. Where a very deep recess is to be filled, it may be necessary to build up in layers. Repairs may be camouflaged if required by covering surface with cement powder before full cure is affected.
Working temperature:
CONCRESIVE 2200 will cure at temperatures as low as 0°C, although at low temperatures cure is retarded.
Coverage
3kg is sufficient to cover 1.1m² at 1.5mm thickness.
Equipment care
Clean with CLEANING SOLVENT NO. 2 immediately after use.
Safety precautions
As with all chemical products, care should be taken during use and storage to avoid contact with eyes, mouth, skin and foodstuffs (which can also be tainted with vapour until product is fully cured or dried). Treat splashes to eyes and skin immediately. If accidentally ingested, seek immediate medical attention. Keep away from children and animals. Reseal containers after use. For further information refer to the material safety data sheet.
Storage
Store under cover out of direct sunlight and protect from extremes of temperature. In tropical climates the product must be stored in an air conditioned environment. Failure to comply with the recommended storage conditions may result in premature deterioration of the product or packaging. For specific storage advice consult BASF's Technical Services Department.
