What are non-shrink grouts?
Grouts are something that are commonly used by the construction industry for the purpose of filling up the gap between tiles or concrete elements. Non-shrink grouts are hydraulic cement grouts which when used stay the same size as the volume of the mixture poured, or higher than the original volume. They are used to fill up the differences between the two structures, as they are thinner, and they get poured into the gaps easily and effortlessly. Below are some of the most common uses of cementitious non-shrink grouts:
- Structural column base plates
- Pump and machinery bases
- Anchor Bolts
- Dowels
- Bearing pads
- Keyway joints
For best use, construction chemical manufacturing companies in UAE suggest to preparing the surfaces receiving a non shrink grout. Surfaces must be clear of any foreign substances such as grease, oil, paint, and dust. It is best to clean surfaces thoroughly and ensure that the existing concrete or stabilizer is stable and sound.
Purpose of using non-shrink grouts
Non-shrink grout is a high strength, structural grout that can be used in many grouting purposes such as:
- Grouting under baseplates, columns and equipment not subjected to heavy impact or vibratory loads.
- Grout jacking of concrete slabs
- Grouting of anchor bolts
- Underpinning of structures
- Grouting holes or cracks in concrete
- Void backfilling in tunnels
- Grouting of post-tensioned structural sections
- Underpinning and brickwork repairs
- Patching holes in masonry surfaces
Non shrink grouts from Corrotech
CORROGROUT HS – Corrogrout HS is a premixed & bagged blend of cement, aggregates & special polymers. This non shrink grout is commonly used for grouting heavy duty applications such as machine base plates, column bases, and crane rails but it can also be used as an anchoring grout around threaded or high yield bolts for balustrades, fences and barriers.
CORROGROUT GP – Same with the Corrogrout HS, Corrogrout GP is also a premixed & bagged blend of cement, aggregates & special polymers. Its general uses include column bases, tie bolt holes and joints between precast elements, but it can also be used as an anchoring grout around threaded or high yield bolts for balustrades, fences and barriers.
From simple void filling to precision engineering applications Corrotech have a vast range of non-shrink grout to meet every situation. For more information, visit their website at https://www.mctuae.com/.
